Dendritic Cells Revisited.

Dendritic cells (DCs) possess the ability to integrate information about their environment and communicate it to other leukocytes, shaping adaptive and innate immunity. Over the years, a variety of cell types have been called DCs on the basis of phenotypic and functional attributes. Here, we refocus attention on conventional DCs (cDCs), a discrete cell lineage by ontogenetic and gene expression criteria that best corresponds to the cells originally described in the 1970s. We summarize current knowledge of mouse and human cDC subsets and describe their hematopoietic development and their phenotypic and functional attributes. We hope that our effort to review the basic features of cDC biology and distinguish cDCs from related cell types brings to the fore the remarkable properties of this cell type while shedding some light on the seemingly inordinate complexity of the DC field.

Distinct ontogenetic lineages dictate cDC2 heterogeneity.

Conventional dendritic cells (cDCs) include functionally and phenotypically diverse populations, such as cDC1s and cDC2s. The latter population has been variously subdivided into Notch-dependent cDC2s, KLF4-dependent cDC2s, T-bet+ cDC2As and T-bet- cDC2Bs, but it is unclear how all these subtypes are interrelated and to what degree they represent cell states or cell subsets. All cDCs are derived from bone marrow progenitors called pre-cDCs, which circulate through the blood to colonize peripheral tissues. Here, we identified distinct mouse pre-cDC2 subsets biased to give rise to cDC2As or cDC2Bs. We showed that a Siglec-H+ pre-cDC2A population in the bone marrow preferentially gave rise to Siglec-H- CD8α+ pre-cDC2As in tissues, which differentiated into T-bet+ cDC2As. In contrast, a Siglec-H- fraction of pre-cDCs in the bone marrow and periphery mostly generated T-bet- cDC2Bs, a lineage marked by the expression of LysM. Our results showed that cDC2A versus cDC2B fate specification starts in the bone marrow and suggest that cDC2 subsets are ontogenetically determined lineages, rather than cell states imposed by the peripheral tissue environment.

The phospho-docking protein 14-3-3 regulates microtubule-associated proteins in oocytes including the chromosomal passenger Borealin.

Global regulation of spindle-associated proteins is crucial in oocytes due to the absence of centrosomes and their very large cytoplasmic volume, but little is known about how this is achieved beyond involvement of the Ran-importin pathway. We previously uncovered a novel regulatory mechanism in Drosophila oocytes, in which the phospho-docking protein 14-3-3 suppresses microtubule binding of Kinesin-14/Ncd away from chromosomes. Here we report systematic identification of microtubule-associated proteins regulated by 14-3-3 from Drosophila oocytes. Proteins from ovary extract were co-sedimented with microtubules in the presence or absence of a 14-3-3 inhibitor. Through quantitative mass-spectrometry, we identified proteins or complexes whose ability to bind microtubules is suppressed by 14-3-3, including the chromosomal passenger complex (CPC), the centralspindlin complex and Kinesin-14/Ncd. We showed that 14-3-3 binds to the disordered region of Borealin, and this binding is regulated differentially by two phosphorylations on Borealin. Mutations at these two phospho-sites compromised normal Borealin localisation and centromere bi-orientation in oocytes, showing that phospho-regulation of 14-3-3 binding is important for Borealin localisation and function.

Neutrophil immune profile guides spinal cord regeneration in zebrafish.

Spinal cord injury triggers a strong innate inflammatory response in both non-regenerative mammals and regenerative zebrafish. Neutrophils are the first immune population to be recruited to the injury site. Yet, their role in the repair process, particularly in a regenerative context, remains largely unknown. Here, we show that, following rapid recruitment to the injured spinal cord, neutrophils mostly reverse migrate throughout the zebrafish body. In addition, promoting neutrophil inflammation resolution by inhibiting Cxcr4 boosts cellular and functional regeneration. Neutrophil-specific RNA-seq analysis reveals an enhanced activation state that correlates with a transient increase in tnf-α expression in macrophage/microglia populations. Conversely, blocking neutrophil recruitment through Cxcr1/2 inhibition diminishes the presence of macrophage/microglia at the injury site and impairs spinal cord regeneration. Altogether, these findings provide new insights into the role of neutrophils in spinal cord regeneration, emphasizing the significant impact of their immune profile on the outcome of the repair process.

The recombinant L-lysine α-oxidase from the fungus Trichoderma harzianum promotes apoptosis and necrosis of leukemia CD34 + hematopoietic cells.

BACKGROUND: In hematologic cancers, including leukemia, cells depend on amino acids for rapid growth. Anti-metabolites that prevent their synthesis or promote their degradation are considered potential cancer treatment agents. Amino acid deprivation triggers proliferation inhibition, autophagy, and programmed cell death. L-lysine, an essential amino acid, is required for tumor growth and has been investigated for its potential as a target for cancer treatment. L-lysine α-oxidase, a flavoenzyme that degrades L-lysine, has been studied for its ability to induce apoptosis and prevent cancer cell proliferation. In this study, we describe the use of L-lysine α-oxidase (LO) from the filamentous fungus Trichoderma harzianum for cancer treatment. RESULTS: The study identified and characterized a novel LO from T. harzianum and demonstrated that the recombinant protein (rLO) has potent and selective cytotoxic effects on leukemic cells by triggering the apoptotic cascade through mitochondrial dysfunction. CONCLUSIONS: The results support future translational studies using the recombinant LO as a potential drug for the treatment of leukemia.

Analysis of the hikikomori phenomenon - an international infodemiology study of Twitter data in Portuguese.

BACKGROUND: Hikikomori refers to the extreme isolation of individuals in their own homes, lasting at least six months. In recent years social isolation has become an important clinical, social, and public health problem, with increased awareness of hikikomori around the globe. Portuguese is one of the six most spoken languages in the world, but no studies have analysed the content regarding this phenomenon expressed in Portuguese. OBJECTIVE: To explore the hikikomori phenomenon on Twitter in Portuguese, utilising a mixed-methods approach encompassing content analysis, emotional analysis, and correlation analysis. METHODS: A mixed methods analysis of all publicly available tweets in the Portuguese language using a specific keyword (hikikomori) between 1st January 2008 and 19th October 2022. The content analysis involved categorising tweets based on tone, content, and user types, while correlation analysis was used to investigate user engagement and geographical distribution. Statistical analysis and artificial intelligence were employed to classify and interpret the tweet data. RESULTS: Among the total of 13,915 tweets generated, in terms of tone 10,731 were classified as "negative", and 3184 as "positive". Regarding content, "curiosities" was the most posted, as well as the most retweeted and liked topic. Worldwide, most of the hikikomori related tweets in Portuguese were posted in Europe, while "individuals with hikikomori" were the users most active posting. Regarding emotion analysis, the majority of tweets were "neutral". CONCLUSIONS: These findings show the global prevalence of the discourse on hikikomori phenomenon among Portuguese speakers. It also indicates an increase in the number of tweets on this topic in certain continents over the years. These findings can contribute to developing specific interventions, support networks, and awareness-raising campaigns for affected individuals.

Exploring CDKN1A Upregulation Mechanisms: Insights into Cell Cycle Arrest Induced by NC2603 Curcumin Analog in MCF-7 Breast Cancer Cells.

Breast cancer stands out as one of the most prevalent malignancies worldwide, necessitating a nuanced understanding of its molecular underpinnings for effective treatment. Hormone receptors in breast cancer cells substantially influence treatment strategies, dictating therapeutic approaches in clinical settings, serving as a guide for drug development, and aiming to enhance treatment specificity and efficacy. Natural compounds, such as curcumin, offer a diverse array of chemical structures with promising therapeutic potential. Despite curcumin's benefits, challenges like poor solubility and rapid metabolism have spurred the exploration of analogs. Here, we evaluated the efficacy of the curcumin analog NC2603 to induce cell cycle arrest in MCF-7 breast cancer cells and explored its molecular mechanisms. Our findings reveal potent inhibition of cell viability (IC50 = 5.6 µM) and greater specificity than doxorubicin toward MCF-7 vs. non-cancer HaCaT cells. Transcriptome analysis identified 12,055 modulated genes, most notably upregulation of GADD45A and downregulation of ESR1, implicating CDKN1A-mediated regulation of proliferation and cell cycle genes. We hypothesize that the curcumin analog by inducing GADD45A expression and repressing ESR1, triggers the expression of CDKN1A, which in turn downregulates the expression of many important genes of proliferation and the cell cycle. These insights advance our understanding of curcumin analogs' therapeutic potential, highlighting not just their role in treatment, but also the molecular pathways involved in their activity toward breast cancer cells.

Cytotoxic activity of l-lysine alpha-oxidase against leukemia cells.

Cancer cells exhibit higher proliferation rates than normal cells, and as a consequence, a higher nutritional demand for metabolites such as amino acids. Such cells demonstrate high expression of amino acid transporters and are significantly dependent on the external uptake of amino acids. Moreover, some types of cancer cells exhibit oncogenic mutations that render them auxotrophic to certain amino acids. This metabolic difference between tumor and normal cells has been explored for developing anticancer drugs. Enzymes capable of depleting certain amino acids in the bloodstream can be employed to inhibit the proliferation of cancer cells and promote cell death. Certain microbial enzymes, such as l-asparaginase and l-amino acid oxidases, have been studied for this purpose. In this paper, we discuss the role of l-asparaginase, the only enzyme currently used as a chemotherapeutic agent. We also review the studies on a new potential antineoplastic agent, l-lysine α-oxidase, an enzyme of l-amino acid oxidase family.

Investigating time-dependent COVID-19 pandemic mental health data: Challenges and opportunities of using panel data analysis.

Mariana Pinto da Costa and Robert Stewart provide commentary on a large prospective panel survey of mental health during the pandemic and consider the implications of such data science initiatives.

The role of the pharmacist in the hospital discharge of cancer patients: an integrative review.

INTRODUCTION: Patients with cancer need care from a multidisciplinary team due to the complexity of the clinical picture and proposed treatment. Hospital discharge is a critical step, because pharmacotherapy changes may occur during hospitalization, leading to potential medication-related problems at home. OBJECTIVE: To identify publications which describe the activities performed by the pharmacist at the hospital discharge of patients with cancer. METHOD: This is an integrative systematic literature review. A search was carried out in the MEDLINE databases, via Pubmed, Embase, and Virtual Health Library, using the following descriptors: "Patient Discharge", "Pharmacists", "Neoplasms." Studies that reported activities performed by the pharmacist at the hospital discharge of patients with cancer were included. RESULTS: Five hundred and two studies were identified, of which seven met the eligibility criteria. Most were conducted in the United States (n = 3), and the rest in Belgium, Brazil, Canada, and Italy. Among the services provided by the pharmacist at discharge, medication reconciliation was the most widely described. Other activities such as counseling, education, identification, and resolution of drug-related problems were also carried out. CONCLUSION: In the scenario of hospital discharge of patients with cancer, the participation of pharmacists is still to be seen as of significance in regards to publications. Despite this, the results suggest that the actions of this professional contribute to patient orientation and the safe use of prescription drugs for use at home.

The role of family doctors in the management of domestic violence cases - a qualitative study in Portugal.

BACKGROUND: Domestic violence leads to multiple health problems in victims and their families. Family doctors are in a particularly privileged position to detect, follow up, refer and report cases of domestic violence. However, little is known about the perception of these physicians regarding their role in managing domestic violence cases. METHODS: We conducted semi-structured interviews with family doctors from all regional health administrations of continental Portugal. Interviews were audio recorded, transcribed, and analysed using thematic analysis. RESULTS: Fifty-four family doctors participated in this study (n = 39 women, n = 15 men). The themes and subthemes that emerged from the data analysis translated doctors' broad responsibilities when approaching victims and aggressors. These included: "Implement preventive measures", "Empower the victim leading them to recognize the violent situation", "Detect domestic violence cases", "Treat health problems related to violence", "Provide emotional support", "Refer victims to specialized services", "Register the episode on the victims and/or aggressor clinical records", "Incentivize the victim to report", "Report the case to the authorities", "Intervene with the aggressor", "Protect other individuals" and "Follow up the patient and the process". CONCLUSIONS: The results of this study provide an overview of the current practical approaches being adopted by physicians and may provide a base for developing new interventions to support physicians to manage cases of domestic violence.

Clinical Communication Within Hospital Pharmacy Practice: Exploring Pharmaceutical Oncological Consultations.

This exploratory study aimed to identify communication trends typical of pharmacists' clinical communication in the context of hospital consultations. A cross-sectional design was used to investigate the pharmacist-patient exchange, applying the Roter Interaction Analysis System (RIAS). Communication variables and RIAS composites were assessed, including therapeutic information complexity, estimated through the ad-hoc score CTICS (Cancer Therapy Information Complexity Score). The study comprised 13 consultations of cancer patients with one female pharmacist, of which 6 included a patient family member, lasting on average 22.74 minutes and presenting repeated or overlapping consultation phases. The pharmacist's talk dominance reached 53.49%, slightly higher in dyadic consultations (U = 6.0, p = .032), and with an overall predominance of closed-ended questioning (W = 81.0, p = .013). Patients' questioning on biomedical issues was higher in dyadic consultations. The level of the pharmacist's rapport-building with the relative was higher when the patient's age was ≥80 years. Several strong correlations, both positive and negative, were found between composites, including between patient positive rapport-building and relative lifestyle/psychosocial information giving (Rho = -0.971, p = .001). Pharmaceutical consultations seem to be lengthier than other hospital practitioners' interviews, indicating a lack of  clear organization and flow, thus challenging their efficiency regarding therapy management. Still, several positive communication features were found regarding the pharmaceutical care of older cancer patients. Further studies are needed, involving larger samples and other hospital consultation settings.

Understanding Public Perceptions and Discussions on Opioids Through Twitter: Cross-Sectional Infodemiology Study.

BACKGROUND: Opioids are used for the treatment of refractory pain, but their inappropriate use has detrimental consequences for health. Understanding the current experiences and perceptions of patients in a spontaneous and colloquial environment regarding the key drugs involved in the opioid crisis is of utmost significance. OBJECTIVE: The study aims to analyze Twitter content related to opioids, with objectives including characterizing users participating in these conversations, identifying prevalent topics and gauging public perception, assessing opinions on drug efficacy and tolerability, and detecting discussions related to drug dispensing, prescription, or acquisition. METHODS: In this cross-sectional study, we gathered public tweets concerning major opioids posted in English or Spanish between January 1, 2019, and December 31, 2020. A total of 256,218 tweets were collected. Approximately 27% (69,222/256,218) were excluded. Subsequently, 7000 tweets were subjected to manual analysis based on a codebook developed by the researchers. The remaining databases underwent analysis using machine learning classifiers. In the codebook, the type of user was the initial classification domain. We differentiated between patients, family members and friends, health care professionals, and institutions. Next, a distinction was made between medical and nonmedical content. If it was medical in nature, we classified it according to whether it referred to the drug's efficacy or adverse effects. In nonmedical content tweets, we analyzed whether the content referred to management issues (eg, pharmacy dispensation, medical appointment prescriptions, commercial advertisements, or legal aspects) or the trivialization of the drug. RESULTS: Among the entire array of scrutinized pharmaceuticals, fentanyl emerged as the predominant subject, featuring in 27% (39,997/148,335 posts) of the tweets. Concerning user categorization, roughly 70% (101,259/148,335) were classified as patients. Nevertheless, tweets posted by health care professionals obtained the highest number of retweets (37/16,956, 0.2% of their posts received over 100 retweets). We found statistically significant differences in the distribution concerning efficacy and side effects among distinct drug categories (P<.001). Nearly 60% (84,401/148,335) of the posts were devoted to nonmedical subjects. Within this category, legal facets and recreational use surfaced as the most prevalent themes, while in the medical discourse, efficacy constituted the most frequent topic, with over 90% (45,621/48,777) of instances characterizing it as poor or null. The opioid with the greatest proportion of tweets concerning legal considerations was fentanyl. Furthermore, fentanyl was the drug most frequently offered for sale on Twitter, while methadone generated the most tweets about pharmacy delivery. CONCLUSIONS: The opioid crisis is present on social media, where tweets discuss legal and recreational use. Opioid users are the most active participants, prioritizing medication efficacy over side effects. Surprisingly, health care professionals generate the most engagement, indicating their positive reception. Authorities must monitor web-based opioid discussions to detect illicit acquisitions and recreational use.

Cerebral venous thrombosis following an immunoglobulin-E mediated anaphylactic reaction.

BACKGROUND: Prothrombotic and pro-inflammatory states are known cerebral venous thrombosis risk factors. To date, two cases of venous thrombotic events after immunoglobulin-E mediated anaphylaxis have been reported. Herein, we describe the first case of cerebral venous thrombosis in close temporal relation with an immunoglobulin-E mediated anaphylactic event. CASE DESCRIPTION: A 51-year-old female presented with headache, language, and mental disturbance lasting for two days. Two days before the onset, she had undergone a provocative test with deflazacort to study an allergy history; after the test she developed a severe anaphylactic reaction. There were no other comorbidities, and in addition to contraceptive pill, she did not take other medications. On admission the patient was drowsy, with anomic aphasia, inattention and memory impairment. Magnetic Resonance Imaging depicted a left caudate and lenticulo-capsulo-thalamic venous infarct and thrombosis in the deep venous system. The patient was treated with anticoagulation and showed progressive improvement. Neoplastic and pro-thrombotic diseases were excluded. CONCLUSION: The close temporal association between the anaphylactic reaction and cerebral venous thrombosis suggests that anaphylactic reaction could have been a cerebral venous thrombosis precipitating factor. Immunoglobulin-E have been suggested to have prothrombotic activity by stimulating the release of platelet activation factor, thromboxane A2 and serotonin. This case adds on to the available information on possible cerebral venous thrombosis associated conditions.

A rare cause of severe esophagitis in an immunocompetent patient - double complication with an endoscopic resolution.

A 75-year-old male, without relevant medical history and negative HIV1/2 serology, presented at the emergency department with mixed shock (septic - from pleuroparenchymal origin - and hypovolemic due to upper gastrointestinal bleeding [UGIB]). Thoracoabdominal CT scan showed an esophagopleural fistula (EPF), with a large right pleural effusion (lately known to be compatible with exudate - Light's criteria) and right pneumothorax, without active bleeding. The upper gastrointestinal endoscopy (UGIE) showed a severe esophagitis and, in distal oesophagus, an ulcer with an orifice in the center. Biopsies of the edges of the ulcer were performed. Anatomopathological (AP) studies were negative for viral agents but tissue molecular studies (polymerase chain reaction [PCR]) identified cytomegalovirus (CMV) DNA. Despite no immunosuppression condition was identified, CMV severe esophagitis complicated by EPF with right-side empyema and UGIB was diagnosed. An oesophageal fully covered metal stent (FCMS), with anti-migration system, was left in place during 5-weeks and ganciclovir therapy (5mg/kg/day) was maintained for 21-days. Clinical-analytical, radiological and endoscopic improvement was noticed. No recurrence in the following year of follow-up.

Global research trends of studies related to mouthguards and dental injuries in sports activities: a bibliometric analysis.

Mouthguards (MGs) are essential devices for the protection of sports-related orofacial injuries. Mapping of the literature on this subject may help to guide future studies; therefore, this review aimed to characterize the research trends of studies related to MGs and dental injuries in sports activities through bibliometric analysis of in vivo studies concerning the frequency of MG use; knowledge, awareness, perception, and/or attitude about MGs; and adaptation (fit) of MGs in the mouth and/or prevention of traumatic dental injuries (TDIs). A literature search was performed in 6 databases for studies published up to April 2022. Text mining and analysis software was used to extract and evaluate data related to the study author, country, keywords, journal of publication, and year. Additionally, data related to the type of study, outcome, study population, age group, evaluation method, type of MG, sport classification, and sport category were extracted and analyzed. Of 6140 records identified, 222 were included in the analysis. Most of the articles came from the United States (n = 39; 17.5%) and dentistry journals (n = 145; 65.3%). The journal Dental Traumatology (n = 60; 27.0%) presented the highest number of publications. Most studies were observational (n = 195; 87.8%) and evaluated the frequency of MG use (n = 163; 44.4%). Studies were carried out in athletes (n = 181; 82.6%) and adults (n = 169; 49.1%) using questionnaires or interviews for assessment (n = 206; 84.1%). Only 89 (40.1%) studies evaluated the type of MG, mostly involving contact sports. Custom-made MGs were most commonly studied. More studies involving coaches, dentists, and child and teenaged athletes are warranted to help prevent sportsrelated TDIs in young teeth, mainly through interventional studies on the perceptions of and knowledge about MGs among these populations.

An interleukin 6-based genetic risk score strengthened with interleukin 10 polymorphisms associated with long-term kidney allograft outcomes.

Of all kidney transplants, half are still lost in the first decade after transplantation. Here, using genetics, we probed whether interleukin 6 (IL-6) could be a target in kidney transplantation to improve graft survival. Additionally, we investigated if a genetic risk score (GRS) based on IL6 and IL10 variants could improve prognostication of graft loss. In a prospective cohort study, DNA of 1271 donor-recipient kidney transplant pairs was analyzed for the presence of IL6, IL6R, IL10, IL10RA, and IL10RB variants. These polymorphisms and their GRS were then associated with 15-year death-censored allograft survival. The C|C-genotype of the IL6 polymorphism in donor kidneys and the combined C|C-genotype in donor-recipient pairs were both associated with a reduced risk of graft loss (p = .043 and p = .042, respectively). Additionally, the GRS based on IL6, IL6R, IL10, IL10RA, and IL10RB variants was independently associated with the risk of graft loss (HR 1.53, 95%-CI [1.32-1.84]; p < .001). Notably, the GRS improved risk stratification and prediction of graft loss beyond the level of contemporary clinical markers. Our findings reveal the merits of a polygenic IL-6-based risk score strengthened with IL-10- polymorphisms for the prognostication and risk stratification of late graft failure in kidney transplantation.

Psychiatric training in perinatal mental health across Europe.

Perinatal mental illness is associated with considerable maternal and infant morbidity and mortality. However, there are currently no specific guidelines on the standards and structure of postgraduate perinatal psychiatric training in Europe. We describe the characteristics of available and desired specialist perinatal psychiatry training from the perspective of European psychiatrists in training. An online survey was conducted among 34 national psychiatric trainee association representatives of the European Federation of Psychiatric Trainees (EFPT). Participants from the countries in which perinatal psychiatry training was available were invited to participate in in-depth follow-up interviews. Six countries out of 34 (18%) reported that specialist training in perinatal mental health was available (Finland, France, Germany, Ireland, Malta, and the UK). The nature of available training varied in duration, the supervision and assessment model employed, and the training scheme context. Of the 28 countries where specialist perinatal psychiatry training was unavailable, the majority of national representatives (22 countries, 76%) wanted specialist perinatal psychiatry training to be included in their national training curricula. There is a gap between the expected skills and the available training for psychiatrists to meet the mental healthcare needs of women in the perinatal period. Given the prevalence and impact of perinatal mental illness and the expressed desires of trainees themselves for specialist training, this finding should prompt urgent action.

Low appendicular skeletal muscle mass index is associated with the anthropometric variables of post-menopausal women.

BACKGROUND: Skeletal muscle mass is a central component of body composition and its decline is enhanced during aging. We verified the association between the appendicular skeletal muscle mass index (ASMI) with the anthropometric variables, biochemical variables, and lifestyle of postmenopausal women. METHODS: Cross-sectional observational study conducted with postmenopausal women. Sociodemographic, clinical, lifestyle, physical activity level, biochemical, and anthropometric markers were collected. Body composition was assessed by dual-energy densitometry. Multivariate logistic regression analysis was applied. RESULTS: One hundred fourteen women aged in average 66.0 ± 5.8 years were evaluated. There was a significant association between ASMI and age (p = 0.004), body mass (p < 0.001), body mass index (BMI) (p < 0.001), adductor pollicis muscle thickness (APMT) (p < 0.001), plasma calcium levels (p = 0.003), calf circumference (CC), and waist circumference (WC) (p < 0.001 for both). Adjusted regression analyses revealed the influence of BMI, CC, and APMT in the 1st tertile of ASMI (p < 0.05), BMI and CC in the 2rd tertile of ASMI. CONCLUSIONS: ASMI was associated with BMI and muscle mass reserve indicators such as CC and DAPMT. In clinical practice, this indicates that simple, low-cost measures with good applicability can be used to predict and track the risk of depletion of skeletal muscle mass and consequent sarcopenia.

Impact of maternal physical exercise on inflammatory and hypothalamic-pituitary-adrenal axis markers in the brain and lungs of prenatally stressed neonatal mice.

This study aimed to evaluate the effects of maternal exercise on alterations induced by prenatal stress in markers of the inflammatory process and the hypothalamic-pituitary-adrenal axis in the brain and lungs of neonatal mice. Female Balb/c mice were divided into three groups: control, prenatal restraint stress, prenatal restraint stress and physical exercise before and during the gestational period. On day 0 (PND0) and 10 (PND10), mice were euthanized for brain and lung analyses. The gene expression of GR, MR, IL-6, IL-10, and TNF in the brain and lungs and the protein expression of MMP-2 in the lungs were analyzed. Maternal exercise reduced IL-6 and IL-10 gene expression in the brain of PND0 mice. Prenatal stress and maternal exercise decreased GR, MR, IL-6, and TNF gene expression in the lungs of PND0 mice. In the hippocampus of PND10 females, exercise inhibited the effects of prenatal stress on the expression of MR, IL-6, and IL-10. In the lungs of PND10 females, exercise prevented the decrease in GR expression caused by prenatal stress. In the hippocampus and lungs of PND10 males, prenatal stress decreased GR gene expression. Our findings confirm the effects induced by prenatal stress and demonstrate that physical exercise before and during the gestational period may have a protective role on inflammatory changes.
