RESUMEN

BACKGROUND: Carotid plaque (CP) formation is an important consequence of atherosclerosis and leads to significant complications. Levels of neuropeptide Y (NPY), which is a sympathetic neurotransmitter, are elevated in cardiovascular diseases. It also has important roles in inflammatory conditions. This study aimed to explore the relationship between serum NPY and CP and to study further the influence of NPY and inflammatory factors on CP. METHODS: This cross-sectional study was conducted among 300 adults who underwent a health examination at the Second Affiliated Hospital of Fujian Medical University in Fujian Province, of whom 177 were finally enrolled. The participants were divided into the CP (n = 120) and non-CP (NCP) or control (n = 57) groups according to the results of carotid artery color Doppler ultrasound. The CP group was further classified into stable plaque (SP, n = 80) and vulnerable plaque (VP, n = 40) groups based on plaque characteristics. Serum NPY and pro-inflammatory cytokine tumor necrosis factor-α (TNF-α) levels were examined. Univariate and correlation analyses were used to evaluate the correlation between serum NPY levels, pro-inflammatory cytokines, and the CP phenotype. RESULTS: The serum NPY and TNF-α levels of patients in the CP group were significantly higher than those in individuals from the NCP group [ (177.30 ± 43.29) pg.mL- 1 vs. (121.53 ± 40.16)pg.mL- 1, P < 0.001; (41.94 ± 14.19) pg.mL- 1 vs.(33.54 ± 13.37)pg.mL- 1, P = 0.003]. The serum NPY levels of the patients in the VP group were significantly higher than those in patients from the SP group [(191.67 ± 39.87)ng.L- 1 vs.(170.12 ± 43.37)ng.L- 1, P = 0.01, P < 0.05]. Serum TNF-α and NPY levels were positively correlated among patients from the CP group (r = 0.184, P = 0.044). The binary logistic regression analysis showed that serum NPY and TNF-α were independent influencing factors of CP [(OR = 1.029, P < 0.001);(OR = 1.030, P = 0.023)]. The area under the ROC curve of NPY predicting the CP showed statistical significance at a value of 0.819. CONCLUSION: Together, elevated serum NPY levels seem to be associated with the occurrence of coronary atherosclerosis in Chinese adults.

RESUMEN

This study was to investigate three agents possible protective effect against DM-induced cardiovascular dysfunction in spontaneously hypertensive rats (SHR). Control group was fed normal diet, DM group was injected with STZ/NA and fed high fat diet (HFD), and treatment groups were given STZ/NA, fed HFD, and then oral gavaged with eugenosedin-A (Eu-A), glibenclamide (Gli), or pioglitazone (Pio) 5 mg/kg/per day for 4-week, respectively. Eu-A, Gli, and Pio clearly ameliorated the changes of body weight, cardiac weight, and the biochemical parameters, cardiovascular disorders and inflammation. Like Gli and Pio, Eu-A may be effectively to control DM and the cardiovascular dysfunction.

RESUMEN

In past researches, we had been proved the action mechanism of pre-germinated brown rice (PGBR) to treat metabolic syndrome and diabetes mellitus. This study was to investigate the protective effect of PGBR in high fructose and high fat-induced non-alcoholic fatty liver disease (NAFLD) in rodents. WKY rats were divided into: Control group was fed normal drinking water and diet; FLD group was fed 10% high-fructose-water (HFW) and high-fat-diet (HFD); PGBR group was given HFW, and HFD mixed PGBR. After four weeks, the body, hepatic and cardiac weight gains of FLD group had significant increases than that of Control group. The enhanced blood pressure and heart rate, hypertriglyceridemia, hyperuricemia, and higher liver function index (GPT levels) were observed; meanwhile, the IL-6 and TNF-α levels of serum, and TG level of liver were also elevated in FLD group. The related protein expressions of lipid synthesis, inflammation, cardiac fibrosis, and hypertrophy were deteriorated by HFW/HFD. However, in treatment group, PGBR decreased all above influenced parameters, additionally GOT; and related protein expressions. PGBR treated HFW/HFD-induced NAFLD and cardiac complications might be via improving lipid homeostasis, and inhibiting inflammation. Together, PGBR could be used as a healthy food for controlling NAFLD and its' cardiac dysfunction.

RESUMEN

The aim of this study is to discuss the non-catechin flavonoids (NCF) from Camellia sinensis (L.) O. Kuntze seed improving TNF-α impaired insulin stimulated glucose uptake and insulin signaling. Flavonoids had anti-metabolic syndrome and anti-inflammatory properties. It had widely been known for biological activity of catechins in tea, but very few research reports discussed the biological activity of non-catechin flavonoids in tea seed. We used HepG2 cell to treat with 5 µM insulin or with 5 µM insulin + 30 ng/ml TNF-α. Detecting the glucose concentration of medium, insulin decreased the glucose levels of medium meant that insulin promoted glucose uptake into cells, but TNF-α inhibited the glucose uptake effect of insulin. Furthermore, insulin increased the protein expressions of IR, IRS-1, IRS-2, PI3K-α, Akt/PKB, GLUT-2, AMPK, GCK, pyruvate kinase, and PPAR-γ. TNF-α activated p65 and MAPKs (p38, JNK1/2 and ERK1/2), iNOS and COX-2 which worsened the insulin signaling expressions of IR, IRS-1, IRS-2, PI3K-α, Akt/PKB, GLUT-2, AMPK, GCK, pyruvate kinase, and PPAR-γ. We added NCF (500, 1000, 2000 ppm) to cell with insulin and TNF-α. Not only glucose levels of medium were lowered, and the protein expressions of insulin signaling were increased, but p38, JNK1/2, iNOS and COX-2 were also reduced. NCF could ameliorate TNF-α induced insulin resistance through inhibiting p38, JNK1/2, iNOS and COX-2, and suggested that it might be used in the future to help control insulin resistance. This finding is the first report to present the discovery.

RESUMEN

BACKGROUND: Intermittent hypoxia (IH), a typical character of obstructive sleep apnea (OSA), is related to atherogenesis. However, the role of IH on atherosclerosis (AS) progression and the mechanisms involved remains poorly understood. METHODS: In the present study, high-fat fed ApoE-/- mice were treated with recombinant shRNA-TLR4 lentivirus and exposed to IH. Atherosclerotic lesions on the en face aorta and cross-sections of aortic root were examined by Oil-Red O staining. The content of lipids and collagen of aortic root plaques were detected by Oil-Red O staining and Sirius red staining, respectively. The TLR4, NF-κB p65, α-SMA and MOMA-2 expression in aorta and IL-6 and TNF-α expression in the mice serum were also detected. RESULTS: Compared with the Sham group, the IH treated group further increased atherosclerotic plaque loads and plaque vulnerability in the aortic sinus. Along with increased TLR4 expression, enhanced NF-κB activation, inflammatory activity and aggravated dyslipidemia were observed in the IH treated group. TLR4 interference partly inhibited IH-mediated AS progression with decreased inflammation and improved cholesterol levels. Similarly, in endothelial cells, hypoxia/reoxygenation exposure has been shown to promote TLR4 expression and activation of proinflammatory TLR4/NF-κB signaling, while TLR4 interference inhibited these effects. CONCLUSIONS: We found that the IH accelerated growth and vulnerability of atherosclerotic plaque, which probably acted by triggering the activation of proinflammatory TLR4/NF-κB signaling. These findings may suggest that IH is a risk factor for vulnerable plaque and provide a new insight into the treatment of OSA-induced AS progression.

RESUMEN

The symptoms of adult Attention Deficit/Hyperactivity Disorder (ADHD) generally include impaired concentration; an insensitivity to social cues, being hard to get along with, and being internally restlessness. It is not surprising that these problems are likely to affect the performance of college students with ADHD. The study aims to examine whether ADHD symptoms are associated with handedness in college students in Taiwan. A total of 505 male and 645 female participants completed Annett's handedness questionnaire and the Traditional Chinese College ADHD Response Evaluation Student Response Inventory (C-CARE-SRI). Handedness was scored both categorically, mixed vs. not-mixed, and continuously, using the Hand Preference Index. The Inattention score was significantly higher for students who were mixed-handed than for those who were not, after social pressure against using the left hand to write had been adjusted for. However, the differences in Hyperactivity and Impulsivity scores were nonsignificant. In addition, the correlations between all three ADHD and Hand Preference Index factor-scores were nonsignificant. To sum up, mixed-handedness is associated with a higher Inattention score. The potential underlying mechanism relating to ADHD Inattention is discussed.

RESUMEN

To investigate using pre-germinated brown rice (PGBR) to treat metabolic syndrome, we fed one group of mice standard-regular-diet (SRD) for 20 weeks and another group of mice high-fat-diet (HFD) for 16 weeks. We subdivided them into HFD group and HFD + PGBR group whose dietary carbohydrate was replaced with PGBR for 4 weeks. The HFD group gained more weight, had higher blood pressure, heart rate, blood glucose and lipids, liver levels of TG, feces TG and bile acid, lower adipose levels of adipocytokine, lower skeletal muscle IR, IRS-1, IRS-2, PI3 K, Akt/PKB, GLUT-1, GLUT-4, GCK and PPAR-γ; higher liver SREBP-1, SCD-1, FAS, HMGCR, LDLR, CYP7α1 and PPAR-α, and higher adipose SREBP-1, SCD-1, FAS, and lower adipose PPAR-α and adiponectin. The HFD + PGBR group had clearly improved blood pressure, biochemical parameters and above proteins expressions. PGBR successful treatment of metabolic syndrome was achieved through improvements in glucose and lipid synthesis and metabolism.

RESUMEN

OBJECTIVES: This study was designed to establish a murine model of lupus with atherosclerosis, and to investigate the expression of Toll-like receptors (TLRs) in the aorta and kidney. METHODS: The 9-week-old female ApoE-/- and C57BL/6 mice were randomly divided into a ApoE-/- pristane treated group (group A), ApoE-/- control group (group B), C57BL/6 pristane treated group (group C) and C57BL/6 control group (group D). Each mouse was given either a single intraperitoneal injection of 0.5 ml pristane or saline. RESULTS: We observed that group A mice specifically had poor spirit, less activity, obvious hair loss, splenomegalia and renomegaly. Levels of ANA, anti-ds-DNA and anti-Sm antibodies were significantly higher than those in other groups. The group A and B mice generally displayed intimal hyperplasia and atherosclerosis mottling in the lumen of the aorta. The kidney tissues from group A, B and C mice showed increased expression levels of TLR2, TLR4, TLR7 and TLR9 proteins in comparison to group D. However, Group A mice did not show any significant difference in TLR2 and TLR4 protein expression levels when compared to group B and C, but displayed higher TLR7 expression than group B and higher TLR9 expression than group B and C mice. In contrast, the group A and B mice apparently expressed TLR2 and TLR4. CONCLUSIONS: We concluded that pristane treated apoE-/- mice exhibited lupus-like phenotype and developed atherosclerosis. The pristane treatment also induced abnormally high expression of TLR2 and TLR4 in the aorta and TLR2, TLR4, TLR7 and TLR9 in the kidney of apoE-/- mice.

RESUMEN

Pre-germinated brown rice (PGBR) can ameliorate hyperlipidemia, but the action mechanism is not clear. We focus the mechanisms of PGBR prevented hyperlipidemia. Six-week-old mice were divided into: standard-regular diet (SRD), high-fat diet (HFD) and HFD with PGBR (HFD + PGBR) groups for 16 weeks. The HFD group has higher concentrations of TG, TC, HDL and Non-HDL in the blood, and a higher atherosclerosis index (AI). The TG levels in the liver, and TG, bile acid levels in the feces were enhanced; and the total adipocytokines level in adipose tissue was reduced. The HFD group had higher protein expressions of SREBP-1, SCD-1, FAS, LDLR, and CYP7α1 in the liver. Moreover, the greater expressions of SREBP-1, SCD-1, FAS and the less expressions of PPAR-α and adiponectin were in adipose tissue. In the HFD + PGBR group, the PGBR regulated the levels of TG, TC, HDL, Non-HDL, AI and adipocytokines. PGBR increased more cholesterol and bile acid exhaust in feces. The SREBP-1, SCD-1, FAS, HMGCR, LDLR, CYP7α1 and PPAR-α proteins in the liver; and the SREBP-1, SCD-1, FAS, PPAR-α and adiponectin proteins in adipose tissue were reversed by PGBR. Taken together, PGBR can improve lipid synthesis and metabolism, and we suggest PGBR is a recommendable food for controlling hyperlipidemia.

RESUMEN

This study investigated the effect and mechanism of pre-germinated brown rice (PGBR) prevented hyperglycemia in C57BL/6J mice fed high-fat-diet (HFD). Normal six-week-old mice were randomly divided into three groups. Group 1 was fed standard-regular-diet (SRD) and group 2 was fed HFD for 16 weeks. In group 3, the mice were fed a HFD with its carbohydrate replaced with PGBR for 16 weeks. Comparing the SRD and HFD groups, we found the HFD group had higher blood pressure, higher concentrations of blood glucose and HbA1c. The HFD group had less protein expression of insulin receptor (IR), insulin receptor substrate-1 (IRS-1), phosphatidylinositol-3-kinase (PI3K), glucose transporter-4 (GLUT-4) and glucokinase (GCK) and greater expression of glucogen synthase kinase (GSK) in skeletal muscle. The HFD group also had less expression of IR, serine/threonine kinase PI3K-linked protein kinase B (Akt/PKB), AMP-activated protein kinase (AMPK), GCK and peroxisome proliferator-activated receptor γ (PPARγ) in liver. In the HFD + PGBR group, the PGBR could reverse the disorders of blood pressure, blood glucose, HbA1c and increase insulin concentration. PGBR increased the IR, IRS-1, PI3K, Akt, GLUT-1 and GLUT-4 proteins, and ameliorated AMPK, GCK, GSK and PPARγ proteins. Together, PGBR prevented HFD-induced hyperglycemia through improving insulin levels, insulin receptor, glucose transporters and enhancing glucose metabolism.

RESUMEN

BACKGROUND: Apolipoprotein E-knockout (ApoE(-/-)) mice is a classic model of atherosclerosis. We have found that ApoE(-/-) mice showed splenomegaly, higher titers of serum anti-nuclear antibody (ANA) and anti-dsDNA antibody compared with C57B6/L (B6) mice. However, whether ApoE(-/-) mice show autoimmune injury remains unclear. METHODS AND RESULTS: Six females and six males in each group, ApoE(-/)(-), Fas(-/-) and B6 mice, were used in this study. The titers of serum ANA, anti-dsDNA antibody and creatinine and urine protein were measured by ELISA after 4 months of high-fat diet. The spleen weight and the glomerular area were determined. The expressions of IgG, C3 and macrophage in kidney and atherosclerotic plaque were detected by immunostaining followed by morphometric analysis. Similar to the characteristics of Fas(-/-) mice, a model of systemic lupus erythematosus (SLE), ApoE(-/-) mice, especially female, displayed significant increases of spleen weight and glomerular area when compared to B6 mice. Also, elevated titers of serum ANA, anti-dsDNA antibody and creatinine and urine protein. Moreover, the expressions of IgG, C3 and macrophage in glomeruli and aortic plaques were found in ApoE(-/-) mice. In addition, the IgG and C3 expressions in glomeruli and plaques significantly increased (or a trend of increase) in female ApoE(-/-) mice compared with males. CONCLUSIONS: Apolipoprotein E-knockout mice on high-fat diet show autoimmune injury on kidney and aorta.

RESUMEN

In this study the effects of low-dose aspirin (5 mg/kg) on adhesion molecule and chemokine expression in a hyperlipidemic rat model. Six-week-old Sprague-Dawley (SD) rats were assigned to two control groups receiving either a regular diet or high-fat diet (HFD) and a treatment group fed HFD with 5 mg/kg aspirin for a 10-week period. Compared with the regular diet control group, the HFD control group had higher body weight, lower levels of high-density lipoprotein, higher concentrations of insulin, triglyceride, total cholesterol, and low-density lipoprotein, but no differences in blood glucose and glycated hemoglobin. The prothrombin time (PT) and activated partial thromboplastin time (aPTT) were clearly shortened in the HFD group. That group also had increased expression of intercellular adhesion molecule-1 (ICAM-1), ICAM-2, ICAM-3, vascular cell adhesion molecule (VCAM), platelet endothelial cell adhesion molecule (PECAM) and P-selectin in platelets and vascular adhesion protein-1 in lymphocyte and in aorta increased expressions of ICAM-1, ICAM-2, ICAM-3, VCAM, PECAM, E-selectin, monocyte chemoattractant protein-1 (MCP-1) and CCR2. The HFD rats also had increased PKCα, IκB kinase α (IKKα), p65, mitogen-activated protein kinases (MAPKs) (p38, c-Jun N-terminal kinases 1, extracellular signal-regulated kinase 1/2), and their phosphorylated forms. Low-dose aspirin improved HFD-induced hyperinsulinemia and hyperlipidemia, recovered PT and aPTT, inhibited upregulation of adhesion molecules and chemokines and reduced expression of PKCα, IKKα, p65, and MAPKs. Low-dose aspirin ameliorates HFD-induced hyperlipidemia and hyperinsulinemia, and prevents HFD-induced expression of adhesion molecules and chemokine formation.

RESUMEN

BACKGROUND: Previous reports have suggested that coronary computed tomography angiography (CCTA)-based radiomics analysis is a potentially helpful tool for assessing vulnerable plaques. We aimed to investigate whether coronary radiomic analysis of CCTA images could identify vulnerable plaques in patients with stable angina pectoris. METHODS: This retrospective study included patients initially diagnosed with stable angina pectoris. Patients were randomly divided into either the training or test dataset at an 8 : 2 ratio. Radiomics features were extracted from CCTA images. Radiomics models for predicting vulnerable plaques were developed using the support vector machine (SVM) algorithm. The model performance was assessed using the area under the curve (AUC); the accuracy, sensitivity, and specificity were calculated to compare the diagnostic performance using the two cohorts. RESULTS: A total of 158 patients were included in the analysis. The SVM radiomics model performed well in predicting vulnerable plaques, with AUC values of 0.977 and 0.875 for the training and test cohorts, respectively. With optimal cutoff values, the radiomics model showed accuracies of 0.91 and 0.882 in the training and test cohorts, respectively. CONCLUSION: Although further larger population studies are necessary, this novel CCTA radiomics model may identify vulnerable plaques in patients with stable angina pectoris.

RESUMEN

To investigate the pathologic mechanisms of toll-like receptor 4 (TLR4) in lung injury and atherosclerosis, ApoE⁻/⁻ or wild-type mice were intraperitoneally administered saline, lipopolysaccharides (LPS), or LPS plus TAK-242 (TLR4 inhibitor), respectively, twice a week for 4 weeks. Serum autoantibody of antinuclear antibody (ANA), anti-double-stranded DNA (anti-dsDNA), and cytokines of interferon-gamma (IFN-γ), tumor necrosis factor (TNF-α ), and interleukin-1 (IL-1ß) were assessed by ELISA. Hematoxylin and eosin (HE) and Perl's stains for lung pathomorphology as well as HE staining for atherosclerosis were employed. TLR4 in macrophages was detected by double immunofluorescent staining. While protein expressions of TLR4, nuclear factor-kappa B p65 (NF-κB p65), and B cell activating factor belonging to the TNF family (BAFF) were examined by immunohistochemistry. We found that serum autoantibody (ANA and anti-dsDNA), cytokines (IFN-γ, TNF-α, IL-1ß), lung inflammation, and intima-media thickness in brachiocephalic artery were obviously increased after LPS challenge in both genotypes, but to a lesser extent in wild-type strains. And those alterations were alleviated by coadministration of LPS and TAK-242. Mechanistically, upregulation of TLR4, NF-κb, and BAFF was involved. We concluded that TLR4/NF-κb/BAFF in macrophages might be a possible common autoimmune pathway that caused lung injury and atherosclerosis. TLR4 signal will be a therapeutic target in atherosclerosis and immune-mediated lung injury.

RESUMEN

Apolipoprotein E-knockout (ApoE(-/-)) mice, atherosclerosis-prone mice, show an autoimmune response, but the pathogenesis is not fully understood. We investigated the pathogenesis in female and male ApoE(-/-) mice. The spleens of all ApoE(-/-) and C57BL/6 (B6) mice were weighed. The serum IgG level and titers of anti-nuclear antibody (ANA) and anti-double-stranded DNA (anti-dsDNA) antibody were assayed by ELISA. Apoptosis of spleen tissue was evaluated by TUNEL. TLR4 level in spleen tissue was tested by immunohistochemistry and Western blot analysis. Levels of MyD88, p38, phosphorylated p38 (pp38), interferon regulatory factor 3 (IRF3) and Bcl-2-associated X protein (Bax) in spleen tissue were detected by Western blot analysis. We also survey the changes of serum autoantibodies, spleen weight, splenocyte apoptosis and the expressions of TLR4, MyD88, pp38, IRF3 and Bax in spleen tissue in male ApoE(-/-) mice after 4weeks of lipopolysaccharide (LPS), Toll-like receptor 4 ligand, administration. ApoE(-/-) mice showed splenomegaly and significantly increased serum level of IgG and titers of ANA and anti-dsDNA antibody as compared with B6 mice. Splenocyte apoptosis and the expression of TLR4, MyD88, pp38, IRF3 and Bax in spleen tissue were significantly lower in ApoE(-/-) than B6 mice. The expression of TLR4, MyD88, IRF3, pp38, and Bax differed by sex in ApoE(-/-) spleen tissue. The down-regulation of TLR4 signal molecules induced by LPS led to decreased expression of Bax and increased serum titers of ANA and anti-dsDNA antibody. Therefore, the TLR4 signal pathway may participate in maintaining the balance of splenocyte apoptosis and autoantibody production in ApoE(-/-) mice.

RESUMEN

Seven new sesquiterpenoids, lochmolins A-G (1-7), were isolated from a Taiwanese soft coral Sinularia lochmodes. The structures of these metabolites were elucidated by extensive spectroscopic study. Compounds 1-4 were found to inhibit the accumulation of the LPS-induced pro-inflammatory COX-2 protein in RAW264.7 macrophage cells.

RESUMEN

During the 2020 COVID-19 pandemic in Taiwan, 6.5% of Generation Y required medical treatment for emotional and stress-related mental disorders. This study explores the moderating effect of mindfulness training on psychological needs and emotions to propose effective measures to promote the mental health of Generation Y. This study was carried out by questionnaire, using the data of respondents born in 1980-1999, collected in three different periods for quantitative analysis with compassionate mindfulness as the main variable. The results show that the compassionate mindfulness effect on emotion regulation varies greatly among different educational levels. However, it still plays a positive role in the psychological needs of Generation Y. Most members of Generation Y who receive compassionate mindfulness training have fewer basic needs and more interpersonal trust. They pay more attention to individual-oriented self-realization. Compassionate mindfulness has a greater positive moderating effect on the mental health of women aged 30-39 and those who are highly educated. Compassionate mindfulness has a more positive moderating effect on the psychological needs of members of Generation Y who were born more recently. During the COVID-19 pandemic, providing compassionate mindfulness has a significant positive effect on the prevention of mental disorders of Generation Y in Taiwan.

RESUMEN

This study aimed to examine the depression risk factors for knowledge workers aged 20-64 in the post-capitalist society of Taiwan. Interview data from 2014 and 2019 were adopted for quantitative analysis of the depression risk by demographic and individual characteristics. The results showed that the depression risks of knowledge workers were not affected by demographic variables in a single period. From 2014 to 2019, the prevalence of high depression risk in knowledge workers aged 20-64 years increased over time. The more attention is paid to gender equality in society, the less the change in the gender depression index gap may be seen. Positive psychological state and family relationships are both depression risk factors and depression protective factors. Being male, married, religious, and aged 45-49 years old were found to be critical risk factors. Variables of individual characteristics could effectively predict depression risk.

RESUMEN

Cardiovascular disease (CVD) is a leading cause of mortality worldwide. Atherosclerosis, a multifactorial disease with complicated pathogenesis, is the main cause of CVD, underlying several major adverse cardiovascular events. Obesity is the main cause of obstructive sleep apnea (OSA) and a significant risk for atherosclerosis. OSA is an independent risk factor for CVD. Recent research has focused on understanding the underlying molecular mechanisms by which OSA influences atherosclerosis pathogenesis. The role of exosomes in this process has attracted considerable attention. Exosomes are a type of extracellular vesicles (EV) that are released from many cells (both healthy and diseased) and mediate cell-to-cell communication by transporting microRNAs (miRNAs), proteins, mRNAs, DNA, or lipids to target cells, thereby modulating the functions of target cells and tissues. Intermittent hypoxia in OSA alters the exosomal carrier in circulation and promotes the permeability and dysfunction of endothelial cells, which have been associated with the pathogenesis of atherosclerosis. This review discusses the potential roles of exosomes and exosome-derived molecules in the development and progression of OSA-related atherosclerosis. Additionally, we explore the possible mechanisms underlying OSA-related atherosclerosis and provide new insights for the development of novel exosome-based therapeutics for OSA-related atherosclerosis and CVD.
