HLA-B and AIDS: We will also analyze the relationship between HLAs B*5301 and Cw*0401 epitopes and the clinical status of HIV-infected Cameroonians; as studies of subjects infected with subtype B HIV-1 showed that some HLA alleles such as HLA B*5701 and HLA-B*27 correlate with better immune control and slower progression to AIDS [21,22,23], while other alleles such as HLA-B*5802 correlate with faster disease progression [19,20].
