SFI Resident Professor Tanmoy Bhattacharya and colleagues have published their research on HIV. Their analysis of allelic polymorphisms on host control of HIV revealed complete linkage disequilibrium between HCP5 and HLA-B*5701/HLA-Cw*06, a modest effect of 5’HLA-C on viral set point in the absence of HLA-B*5701, and no influence of the RNF39/ZNRD1 extended haplotype on HIV disease progression.
