GlossaryHLA-DQ

protein complex involved in immune system antigen presentation

HLA-DQ is a protein complex that plays a crucial role in the immune system by helping the body distinguish between its own cells and foreign invaders. It is part of the human leukocyte antigen (HLA) system, specifically involved in presenting antigens to immune cells, which is essential for initiating an immune response. Variations in HLA-DQ genes are associated with susceptibility to certain autoimmune diseases, including type 1 diabetes and celiac disease.
