Association Study of 3-untranslated region Haplotype of Human leukocyte antigen-G Gene with Lupus.

Background: Human leukocyte antigen-G (HLA-G) is a pivotal protein involved in immune regulation and tolerance, while systemic lupus erythematosus (SLE) is a multifaceted autoimmune condition influenced by genetic and environmental factors. Research indicates that variations and mutations in HLA-G may impact SLE development. Objective: This study aimed to explore the relationship between polymorphisms in the 3'-untranslated region (UTR) of the HLA-G gene and SLE. Methods: DNA from 100 SLE patients and 100 controls was analyzed using polymerase chain reaction to amplify the target sequence. Allele and genotype frequencies were determined, and haplotypes were assessed using Haploview v.4.2 software, with linkage disequilibrium calculated. Results: Findings revealed that the +2960 Ins allele was significantly linked to SLE as a risk factor, with the Del allele showing a protective effect. In addition, the +3010C allele and +3187A allele were significantly associated with SLE at both allele and genotype levels. The +3142 GG homozygote was notably linked to SLE at the genotype level. Haplotype analysis identified UTR-2 haplotypes as risk factors for SLE, whereas the UTR-1 haplotype was protective, shedding light on genetic factors influencing SLE risk. Conclusion: This study underscores the importance of HLA-G gene 3'-UTR polymorphisms in SLE susceptibility, suggesting their potential as diagnostic or therapeutic targets.

The role of EZH2 and its regulatory lncRNAs as a serum-based biomarker in Alzheimer's disease.

BACKGROUND: Long noncoding RNAs (lncRNAs) have become a hot topic in the human nervous system. Moreover, circulating lncRNAs have been suggested as possible biomarkers for central nervous system processes and neurodegenerative diseases. The present research aimed to highlight the role of plasma lncRNAs TUG1, FEZF1-AS1, and EZH2 gene as diagnostic biomarkers in Alzheimer's disease (AD). METHODS: Plasma samples for the study were provided by 100 AD patients and 100 matched controls. Real-time quantitative reverse transcriptase PCR was used to determine the plasma level of the aforementioned lncRNAs. Furthermore, the plasma level of EZH2 protein in the participants' blood was determined using the ELISA technique. RESULTS: In contrast to controls, down-regulation of the EZH2 gene and protein was reported in the plasma of patients with AD. Additionally, plasma samples from AD patients showed up-and-down-regulation of the lncRNAs TUG1 and FEZF1-AS1, respectively. CONCLUSION: Our new findings suggest that the EZH2 gene, plasma lncRNA TUG1, and FEZF1-AS1 may contribute, as valuable biomarkers, to AD diagnosis.

Investigation of the impact of copper nanoparticles coated with ocimum bassilicum at chemoradiotherapy of colon carcinoma.

Background: Colon carcinoma poses a significant health challenge globally, particularly in developed nations where sedentary lifestyles, poor dietary choices, and genetic factors play a crucial role in its prevalence. Chemotherapy, the primary treatment method, carries severe side effects that can jeopardize patients' lives. Herbal extracts such as Ocimum Basillicum extract have shown effectiveness against cancer cells. Additionally, nanoparticles can significantly enhance drug delivery efficacy in these scenarios. Aim: This article aims to investigate the impact of copper nanoparticles coated with Ocimum Bassilicum at chemoradiotherapy of Colon Carcinoma to hopefully create new treatment options with fewer side effects for patients. Methodology: CuO bio-NPs were produced by the addition of 15 mL of extract dropwise to 80 mL of a 5 mM Cu (OAc)2 aqueous solution, which was then refluxed for 2 h at 100 °C. The mixture gradually became darker brown in color as a result of the heating procedure. The production of CuO NPs and the hydrogen-donating activity of antioxidant phenols within the plant are signaled by surface plasmon resonance excitation, which is the cause of this. In the cell culture, LS174t colon cancer cells were treated with OB extract, CuNPs, and OB-coated CuNPs with and without different radiation levels in order to assess cell viability, through the MTT assay, and the pro-apoptotic BAX and anti-apoptotic BCL2 expressions, through qPCR assay. Results: The results demonstrate a decrease in cell viability and the expression of BCL2 and an increase in the expression of BAX especially when treated with OB-coated CuNPs and even furthermore when paired with radiation therapy. Conclusions: After doing the clinical trial studies, the recent nanoparticles can be used for the treatment of Colorectal carcinoma.

Downregulation of miR-29a as a possible diagnostic biomarker for schizophrenia.

BACKGROUND: MicroRNAs (miRNAs) are epigenetic factors regulating many genes involved in brain development. Dysregulation of miRNA could result in dysregulation of genes which may contribute to diseases affecting the brain and behavior (e.g., schizophrenia). miR-29 family is a miRNA family contributing to brain maturation. miR-29 knockout in animal studies is reported to correlate with psychiatric disorders very similar to those seen in schizophrenia. In this study, we aimed to evaluate the miR-29a level in patients with schizophrenia and its potential value in the diagnosis of schizophrenia. MATERIALS AND METHODS: The serum sample of 42 patients with schizophrenia and 40 healthy subjects were obtained from the Azeri Recent onset/Acute phase psychosis Survey (ARAS) Cohort study. After preparations, the expression level of miR-29a was investigated by real-time PCR. The SPSS and GraphPad prism software were used to analyze the relation between miR-29a level and clinical parameters and its potential as a biomarker for the diagnosis of schizophrenia. RESULTS: Our study showed a significantly lower miR-29a level in patients compared to healthy controls (p = 0.0012). Furthermore, miR-29a level was significantly lower in some types of schizophrenia (p = 0.024). miR-29a level was not related to sex, age, or heredity (p > 0.05). miR-29a also showed 80% specificity and 71.43% sensitivity in the diagnosis of schizophrenia. CONCLUSION: Downregulation of miR-29a in schizophrenia is significantly related to the development of this illness. It might have the potential as a biomarker for schizophrenia.

Investigating the effectiveness of iron nanoparticles synthesized by green synthesis method in chemoradiotherapy of colon cancer.

Current methods of colon cancer treatment, especially chemotherapy, require new treatment methods due to adverse side effects. One important area of interest in recent years is the use of nanoparticles as drug delivery vehicles since several studies have revealed that they can improve the target specificity of the treatment thus lowering the dosage of the drugs while preserving the effectiveness of the treatment thus reducing the side effects. The use of traditional medicine has also been a favorite topic of interest in recent years in medical research, especially cancer research. In this research work, the green synthesis of Fe nanoparticles was carried out using Mentha spicata extract and the synthesized nanoparticles were identified using FT-IR, XRD, FE-SEM and EDS techniques. Then the effect of Mentha spicata, Fe nanoparticles, and Mentha spicata -loaded Fe nanoparticles on LS174t colon cancer cells, and our result concluded that all three, especially Mentha spicata -loaded Fe nanoparticles, have great cytotoxic effects against LS174t cells, and exposure to radiotherapy just further intensified these results. The in vitro condition revealed alterations in the expression of pro-apoptotic BAX and anti-apoptotic Bcl2, suggesting a pro-apoptotic effect from all three components, particularly the Mentha spicata-loaded Fe nanoparticles. After further clinical trials, these nanoparticles can be used to treat colon cancer.

Comparative evaluation of hesperetin-loaded graphene oxide nanosheets (Hsp-GO) as a drug delivery system for colon cancer: synthesis and anticancer efficiency assessment.

BACKGROUND: Graphene oxide nanosheets (GONS) are recognized for their role in enhancing drug delivery and effectiveness in cancer treatment. With colon cancer being a prevalent global issue and the significant side effects associated with chemotherapy, the primary treatment for colon cancer alongside surgery, there is a critical need for novel therapeutic strategies to support patients in combating this disease. Hesperetin (HSP), a natural compound found in specific fruits, exhibits anti-cancer properties. The aim of this study is to investigate the effect of GONS on the LS174t colon cancer cell line. METHODS: In this study, an anti-cancer nano-drug was synthesized by creating a hesperetin-graphene oxide nanocomposite (Hsp-GO), which was subsequently evaluated for its efficacy through in vitro cell toxicity assays. Three systems were investigated: HSP, GONS, and HSP-loaded GONS, to determine their cytotoxic and pro-apoptotic impacts on the LS174t colon cancer cell line, along with assessing the expression of BAX and BCL2. The morphology and properties of both GO and Hsp-GO were examined using scanning electron microscopy (SEM), X-ray diffraction, and Fourier transform infrared spectroscopy (FTIR). RESULTS: The Hsp-GO nanocomposite displayed potent cytotoxic and pro-apoptotic effects on LS174t colon cancer cells, outperforming individual treatments with HSP or GONS. Cell viability assays showed a significant decrease in cell viability with Hsp-GO treatment. Analysis of BAX and BCL2 expression revealed elevated BAX and reduced BCL2 levels in Hsp-GO treated cells, indicating enhanced apoptotic activity. Morphological analysis confirmed successful Hsp-GO synthesis, while structural integrity was supported by X-ray diffraction and FTIR analyses. CONCLUSIONS: These study highlight the potential of Hsp-GO as a promising anti-cancer nano-drug for colon cancer therapy.

Breast cancer is a prevalent cancer type among women worldwide, with the second highest incidence rate. The objective of this study was to identify a non-invasive biomarker for detecting breast cancer, and to this end, miRNA clusters were investigated as potential candidates. A micro-RNA cluster located on the X chromosome q27.3 region was selected for the study. The research was conducted as a case-control study with a sample size of 100 patients with breast cancer and 100 healthy individuals. Tissue samples from breast cancer tumors and tumor margins were collected from the breast cancer patients. Following RNA extraction and RT-PCR, the expression of miRNA clusters, including miR-506, miR-507, miR-508, miR-509, miR-513, miR-888, miR-891, miR-892-a, and miR-892-b, was analyzed in the serum and breast tissue of the breast cancer patients. The expression of various micro-RNAs in the case and control serums was compared, and it was found that all mentioned micro-RNAs, except mir888-5p and mir-509-3p, exhibited significant and meaningful differences between the patients and control serum groups. These micro-RNAs can be considered as potential tumor markers with a confidence level of P-value = 0.0001. In contrast, mir888-5p and mir-509-3p were considered non-significant. The expression of all micro-RNAs in the tumor margin and BC tumor was significant with a P-value < 0.0001. Based on the ROC curves, all the mentioned microRNAs, except mir-888-5p, mir-513-a-5p, and mir-509-3p, exhibited high sensitivity and specificity and can be considered remarkable non-invasive tumor markers for breast cancer detection.

The following keywords were used: ((primary care OR primary health care) AND (accreditation) AND (impact OR effect OR output OR outcome OR influence OR result OR consequences)). The database search yielded a total of41256 articles, among which 30 articles were finally included in the review. Results: Accreditation showed the most positive impacts on the quality, effectiveness, human resource management and strategic management of PHC services. Accreditation also positively affected safety, responsiveness, accessibility, customer satisfaction, documentation, leadership, efficiency and continuity of care. Few negative impacts were noted, including the possibility of accreditation being used as a bureaucratic tool, high cost of acquiring accreditation, difficulties in understanding the accreditation process, high staff turnover rate in accredited PHC centres and weak sustainability of some accreditation programmes. Conclusion: Given its numerous positive impacts, accreditation could be used to effectively improve the performance of PHC centres.

Expression study of microRNA cluster on chromosome 19 (C19MC) in tumor tissue and serum of breast cancer patient.

BACKGROUND: Breast cancer (BC) is the most prevalent cancer among females worldwide. Numerous studies suggest that specific RNAs play a crucial role in carcinogenesis. The primate-specific microRNA gene cluster located on the 19q27.3 region of chromosome 19 (C19MC) could potentially regulate tumor cell proliferation, migration, and invasion. OBJECTIVE: The objective of this study was to compare the expression of miRNAs from the C19MC cluster in breast cancer tumor and non-tumor samples, as well as in the serum of individuals affected by BC and healthy individuals. METHODS: Peripheral blood was collected from 100 BC patients and 100 healthy individuals, and breast cancer samples including tumor and margin tissues were obtained. After RNA extraction, Real-time PCR was employed to investigate the expression of C19MC, specifically mir-515-1, mir-515-2, mir-516-A1, mir-516-A2, mir-516-B1, mir-516-B2, mir-517-A, mir-517-B, mir-517-C, and mir-518-A1, in the serum and tissue of BC patients and tumor margins. Statistical analyses and ROC curves were generated using GraphPad Prism software (v8.04), with a significance level set at p < 0.05. RESULTS: Our findings demonstrate a strong correlation between high expression of all C19MC miRNAs mentioned, except for mir-517-B, mir-517-C and mir- 518 in BC. These miRNAs show potential as notable non-invasive tumor markers. CONCLUSION: The data obtained from our study support the overall impact of C19MC miRNAs in BC detection and emphasize the potential role of several C19MC members in this process.

Catastrophic health expenditures in hospitalized patients with delta variant of COVID-19: A cross-sectional study.

Background: Financial protection of populations against healthcare costs is one of the fundamental responsibilities of governments. This study aimed to investigate the incidence of catastrophic health expenditures (CHE) and it's affecting factors in hospitalized patients with delta variant of COVID-19. Methods: In this cross-sectional study, we included 400 hospitalized COVID-19 patients at Kosar Hospital of Semnan in 2022, using a researcher-made checklist. Based on qualitative nature of the variables, chi-square test was used to investigate the statistical associations between the demographic/background characteristics and the incidence of CHE. Results: On average, COVID-19 imposed 1833.43 USD direct medical costs per one hospitalized patient. The ratio of direct-medical costs to household's non-food expenses was 2.35, and 61% (CI:±4.78%) of the patients were subject to CHE. Besides, residence place, basic insurance type, benefitting from supplementary insurance, suffering from underlying diseases, hospitalization in ICU, falling into a coma, facing pulmonary failure, and performing hemoperfusion had significant associations with CHE (P<0.05). Conclusion: The incidence of CHE in hospitalized COVID-19 patients was undesirable, which may be due to geographical, economical, and occupational inequalities apart from the factors related to the severity of the disease. So, health policymakers should pay attention to the provision of proper financial risk protection policies to make the health insurance system more efficient and appropriate.

The effect of chitosan hydrogel containing gold nanoparticle complex with paclitaxel on colon cancer cell line.

Colon cancer is a significant global health issue, and its primary treatment, chemotherapy, is limited by toxicity and drug resistance. This has led researchers to explore alternative therapeutic approaches. One such approach is the use of chitosan, a natural biopolymer with anti-cancer properties, and paclitaxel, a potent chemotherapeutic agent with promising activity against many types of cancer. In this study, the effectiveness of a chitosan hydrogel that contains a complex of gold nanoparticles with paclitaxel in treating LS174T colon cancer cell line was investigated. The synthesized chitosan hydrogel was characterized and used to treat the colon cancer cells in cell culture. MTT assay and apoptotic gene expression analysis were conducted to evaluate the complex's effectiveness. The results showed that the chitosan hydrogel-loaded gold nanoparticle-paclitaxel complex exhibited a potent cytotoxic effect against the cancer cells. Moreover, the treatment resulted in a significant increase in pro-apoptotic BAX and BAD expression and a decrease in anti-apoptotic BCL2 expression, indicating a pro-apoptotic effect. These findings suggest that utilizing a chitosan hydrogel that contains a complex of gold nanoparticles with paclitaxel shows promise as a viable treatment option for colon cancer. Further research is needed to determine the potential efficacy and safety of this treatment approach in clinical settings.

An updated review on the significance of DNA and protein methyltransferases and de-methylases in human diseases: From molecular mechanism to novel therapeutic approaches.

Epigenetic mechanisms are crucial in regulating gene expression. These mechanisms include DNA methylation and histone modifications, like methylation, acetylation, and phosphorylation. DNA methylation is associated with gene expression suppression; however, histone methylation can stimulate or repress gene expression depending on the methylation pattern of lysine or arginine residues on histones. These modifications are key factors in mediating the environmental effect on gene expression regulation. Therefore, their aberrant activity is associated with the development of various diseases. The current study aimed to review the significance of DNA and histone methyltransferases and demethylases in developing various conditions, like cardiovascular diseases, myopathies, diabetes, obesity, osteoporosis, cancer, aging, and central nervous system conditions. A better understanding of the epigenetic roles in developing diseases can pave the way for developing novel therapeutic approaches for affected patients.

The Impact of Single Nucleotide Polymorphisms on the Pharmacokinetics of Tacrolimus in Kidney Allograft Recipients of Northern-West, Iran.

Purpose: Calcineurin inhibitors (CNIs) such as tacrolimus are a major immunosuppressive therapy after renal transplantation, which inhibit cytokine expression. The pharmacokinetics of such drugs is influenced by cytochrome P450 (CYP) enzymes, multi-drug resistance-1 (MDR-1), and C25385T pregnane X receptor (PXR). This study aimed to investigate the impact of single nucleotide polymorphisms (SNP) in these genes on the ratio of tacrolimus level per drug dosage (C/D ratio), acute graft rejection, and viral infections. Methods: Kidney transplantation recipients (n=65) under similar immunosuppressive treatment were included. Amplification refractory mutation systempolymerase chain reaction (ARMS-PCR) method was applied to amplify the loci containing the SNPs of interest. Results: Overall, 65 patients with a male/female ratio of 37/28 were included. The mean age was 38±1.75 years. The variant allele frequencies of CYP3A5*3, MDR-1 C3435T, and PXR C25385T were 95.38, 20.77, and 26.92%, respectively. No significant correlations were found between the studied SNPs and the tacrolimus C/D ratios. However, there was a significant difference in the C/D ratios at 2 and 8 weeks in homozygote CYP3A5 *3/*3 carriers (P=0.015). No significant association was found between the studied polymorphisms and viral infections and acute graft rejection (P>0.05). Conclusion: Homozygote CYP3A5 *3/*3 genotype could influence the tacrolimus metabolism rate (C/D ratio).

Altered Expression of the HLA-G and IL10RB Genes in Placental Tissue of Women with Recurrent Pregnancy Loss.

BACKGROUND: Several lines of evidence strongly suggest that the contribution of human leukocyte antigen-G (HLA-G) and interleukin 10 receptor (IL10R) to maternal immunological tolerance toward paternal alloantigens of the embryo limits the activation and function of the maternal immune system. This study is aimed to assess the varia-tion of the mRNA expression levels of HLA-G and IL10RB genes in placental tissue of women with recurrent pregnancy loss (RPL). METHODS: Placental tissue samples were collected from 78 women with a history of at least two consecutive miscarriages and 40 healthy women with no history of pregnancy loss. The expression of HLA-G and IL10RB in placental tissue specimens was evaluated by the quantitative real-time PCR (qPCR) method. Moreover, the correlation be-tween the expression levels of these genes and clinicopathological parameters was analyzed. RESULTS: The results showed that the expression of HLA-G was down-regulated in placental tissues samples of RPL patients compared to healthy subjects, while the expression of IL10RB was up-regulated, but none of them was statistically significant (p-value > 0.05). The mRNA expression levels of HLA-G and IL10RB in placental tissue of RPL patients were negatively correlated with age and number of miscarriages (p-value > 0.05). A significant positive correlation was observed between the expression levels of HLA-G and IL10RB in women with RPL (p-value < 0.05). CONCLUSIONS: The altered expression of HLA-G and IL10RB in placental tissue may contribute to the pathogenesis of RPL and therefore serve as potential therapeutic targets for its prevention.

Investigating the effect of multimedia education based on the health belief model in preventing COVID-19 in pregnant women.

BACKGROUND: Pregnant women are considered one of the high-risk groups during the COVID-19 pandemic, so paying attention to preventive behaviors among them is highly important. This study aimed to examine the effect of multimedia education based on the Health Belief Model (HBM) in preventing COVID-19 among pregnant women. METHODS: This quasi-experimental intervention study was conducted on 120 pregnant women referring to Comprehensive Health Services Centers affiliated with East and West health centres of Ahvaz city, Iran, in 2021. Participants were divided into two control (n = 60) and intervention (n = 60) groups. A researcher-made questionnaire was used for data collection. The intervention group was given the required educational content using social networks virtually and multimedia in 12 sessions. Both groups were reinvestigated after two months. Data were analyzed using SPSS software version 24, independent t-test and paired t-test tests. RESULTS: The mean age and mean gestational age of participants were estimated at 28 years old and 18 weeks, respectively. Before the educational intervention, there was no significant difference in mean constructs of HBM. In contrast, the mean of all constructs increased significantly in the intervention group after intervention. The greatest change was related to the constructs of self-efficacy and perceived susceptibility, and the lowest change was related to the perceived barriers construct. CONCLUSION: Our findings suggest multimedia education using the HBM to COVID-19 preventive behaviors among pregnant women can benefit behavior change.

Changes in the Expression of Long Non-Coding RNA SDMGC and Its Target Gene, TRIM16, in Patients with Gastric Cancer.

PURPOSE: Gastric cancer (GC) has been identified worldwide as one of the most common cancer types with a high mortality rate. LncRNA SDMGC has been recognized as an oncogene with regulatory effects on its target gene, TRIM16, which is believed to play a tumor-suppressing role in various cancers. Both these genes are involved in GC development, tumorigenesis, invasion, and metastasis. The current study is aimed to investigate the association of SDMGC and TRIM16 with GC susceptibility and GC patients' clinicopathological characteristics. METHODS: A total of 100 GC tissues and their corresponding adjacent non-tumor tissues were sampled. Total RNA was then isolated to measure SDMGC and TRIM16 expression levels using quantitative reverse transcriptase (qRT)-PCR. Statistical analyses including the Mann-Whitney U test and correlation tests were carried out using R v4.5. GraphPad Prism was also used to plot the receiver operating curve (ROC). RESULTS: The results demonstrated the significant overexpression of lncRNAs SDMGC and downregulation of TRIM16 in GC tissues as compared to their corresponding marginal normal tissue samples (P = 0.005 and P = 0.009, respectively). No association with clinicopathological variables was observed for either SDMGC or TRIM16. Moreover, the results demonstrated a small positive correlation between SDMGC and TRIM16. Evaluation of the diagnostic value of SDMGC and TRIM16 showed poor biomarker potency for these genes. CONCLUSION: In conclusion, the results indicated an increase in the expression of SDMGC and a decline in the expression pattern of TRIM16 among the Iranian population. The results indicated a key tumor-accelerative function of SDMGC and a pivotal tumor-suppressing role of TRIM16 in GC patients.

Comparative de novo transcriptome analysis of flower and root of Oliveria decumbens Vent. to identify putative genes in terpenes biosynthesis pathway.

The Oliveria decumbens Vent. is a wild, rare, annual medicinal plant and endemic plant of Iran that has metabolites (mostly terpenes) which make it a precious plant in Persian Traditional Medicine and also a potential chemotherapeutic agent. The lack of genetic resources has slowed the discovery of genes involved in the terpenes biosynthesis pathway. It is a wild relative of Daucus carota. In this research, we performed the transcriptomic differences between two samples, flower and root of Oliveria decumbens, and also analyze the expression value of the genes involved in terpenoid biosynthesis by RNA-seq and its essential oil's phytochemicals analyzed by GC/MS. In total, 136,031,188 reads from two samples of flower and root have been produced. The result shows that the MEP pathway is mostly active in the flower and the MVA in the root. Three genes of GPP, FPPS, and GGPP that are the precursors in the synthesis of mono, di, and triterpenes are upregulated in root and 23 key genes were identified that are involved in the biosynthesis of terpenes. Three genes had the highest upregulation in the root including, and on the other hand, another three genes had the expression only in the flower. Meanwhile, 191 and 185 upregulated genes in the flower and root of the plant, respectively, were selected for the gene ontology analysis and reconstruction of co-expression networks. The current research is the first of its kind on Oliveria decumbens transcriptome and discussed 67 genes that have been deposited into the NCBI database. Collectively, the information obtained in this study unveils the new insights into characterizing the genetic blueprint of Oliveria decumbens Vent. which paved the way for medical/plant biotechnology and the pharmaceutical industry in the future.

Evaluation of telomeric KIR genes and their association with CMV infection in kidney transplant recipients.

Cytomegalovirus (CMV) infection is a common complication after organ transplantation. Despite the immunosuppressed state, natural killer (NK) cells remain the major immune defense cells against viral infections in transplanted patients. The present study aimed at elucidating the correlation between the number of inhibitory and activating genes and the incidence of CMV infection in kidney transplanted recipients. Kidney transplanted recipients including 51 CMV+ and 50 CMV- were genotyped for the presence or absence of 4 activating (KIR2DS1, KIR2DS4, KIR2DS5, KIR3DS1) and 2 inhibitory (KIR3DL1, KIR2DL5a) genes using polymerase chain reaction sequence-specific primers (PCR-SSP) assay. Our results showed that CMV infection occurred in 50.49% of kidney allograft recipients. In addition, there was a significant correlation between the presence of the KIR2DS1 activating gene in the CMV- group compared to the CMV+ group (p = 0.033). The other three activating KIR receptors did not show a correlation with CMV infection. Our results suggest that the prevalence of the KIR activating KIR2DS1 gene may reduce the rate of CMV infection after kidney transplantation in our population.
