Objective: Interleukin 1β is a powerful cytokine with a variety of inflammatory functions. This cytokine plays a role in many cellular activities including cell expansion, differentiation, and apoptosis. CTLA4 is an antigen expressed in T lymphocytes has a critical role as inhibitory receptor acting as a major negative regulator of T-cell responses. Material and Methods: Fifty samples of the blood were obtained from CMV patients and a safe control group, then DNA was extracted and analyzed for genotypes IL-1β and CTLA-4 and Alleles with (PCR) and Gel electrophoresis using 2,25%, 2% the concentration of agarose was (respectively) investigated. Results: IL-1β mutations were detected in 58 percent of CMV patients, Although only 44% were observed in the control group, we noticed a substantial correlation between the genotype and the allele frequency and the P<0.05 group of CMV infections. CTLA-4, the G allele correlates with a substantially reduced risk of CMV infections. Conclusion: IL-1β and CTLA-4 are associated with CMV infections.
