Immune response has always been vital to cope with any disease. In context of immune response TNF-α is mainly released by the macrophages as a pro inflammatory cytokine. Studies have shown that HIV infected persons have higher concentration of TNF-α released. A particular single nucleotide polymorphism (SNP) is observed at -308 position of the promoter region of TNF- α gene due to which TNF is categorized into TNF1 and TNF2 allele. TNF2 allele is associated with higher concentration of TNF- α which in turn is associated with HIV infection. In order to know the particular association in the population of Lahore we designed this study. The hypothesis was that SNP at -308 position of the TNF- α may be associated with HIV infection. Methodology was designed as follows: 15 HIV positive samples and 15 HIV negative samples were taken and categorized into group A and B respectively. Whole Blood samples were taken from the patients and subjected to DNA extraction using commercially available kit (Favorgen blood DNA mini extraction kit). Specific primers were used to amplify the particular region (-308) of TNF- α through PCR. A small amount of PCR products were subjected to restriction enzyme Ncol. Sequencing was done and the results were analyzed using specific bioinformatics tools such as NCBI. -308 region of the TNF-alpha was analyzed for the SNPs (TNF1 and TNF2). Collected data was analyzed through SPSS for association studies. Outcome could be as follows: The study is designed to identify SNPs at -308 position of the promoter region of TNF-α gene. It will enable us to understand the possible association between TNF- α and HIV AIDS. It will be the first ever study regarding TNF- α and AIDS in Pakistan.
