UPREGULATION OF SINGLE NUCLEOTIDE POLYMORPHISM OF PD-1 GENE (RS10204525) IN CHRONIC HEPATITIS B PATIENTS
Journal Title: INTERNATIONAL JOURNAL OF RESEARCH IN PATHOLOGY AND MICROBIOLOGY - Year 2018, Vol 2, Issue 3
Abstract
BACKGROUND: Programmed death-1 (PD-1) is major inhibitory molecule that reduces T cell activation. PD-1 and their polymorphisms have separately been shown to be associated with hepatitis B virus (HBV) infection. Therefore, we aimed to investigate the association of PD1 polymorphisms with potential of chronic hepatitis B infection in Iranian population to do a Case –Control study. METHODS: In this study HBV DNA, and Pd-1 mRNA, were extracted from 60 patients with chronic hepatitis B and 60 healthy blood donors as control. HBV Viral Load, polymorphism genotype of the two groups and level expression of Pd1 gene were evaluated using Real time PCR method. RESULTS: Age mean of the control group was 40.7±3.7 and 35.86±11.18 year's old age for the case group. The GG allele between the two groups had the same frequency (73.3% in CHB group and 80% in healthy group). The GA allele in patients with hepatitis B (20%) was most frequent. There was a significant association between the GA allele and chronic hepatitis B infection. There was no significant relationship between the ages of the subjects with SNPrs10204525. Also, the expression of PD-1 mRNA was higher in people with hepatitis B than in healthy group. Conclusion: The results of this study showed that there is a significant relationship between the presence of rs10204525 polymorphisms in the PD-1 gene in patients with chronic hepatitis B infection and the association between the GA allele and chronic hepatitis B can be linked
