The HLA gene family provides instructions for making a group of related proteins known as the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body's own proteins from proteins made by foreign invaders such as viruses and bacteria.HLA is the human version of the major histocompatibility complex (MHC), a gene family that occurs in many species.here are six main MHC class II genes in humans: HLA-DPA1, HLA-DPB1, HLA-DQA1, HLA-DQB1, HLA-DRA, and HLA-DRB1. MHC class II genes provide instructions for making proteins that are present almost exclusively on the surface of certain immune system cells.
Many people with HIV also have problems with their levels of white blood cells (leukocytes). Leukocytes are white blood cells that respond to and protect the body from infection. HIV can attack leukocytes.When the number of white blood cells decreases, a dangerous condition called leukopenia can develop, which makes the body more prone to infections. The specific type of white blood cells that respond directly to infection are called neutrophils.any people with HIV also have problems with their levels of white blood cells (leukocytes). Leukocytes are white blood cells that respond to and protect the body from infection. HIV can attack leukocytes.
