Introduction The human leukocyte antigen (HLA) system is one of the most polymorphic genetic systems in humans, playing a central role in the regulation of immune responses. Among the HLA class II haplotypes, DR4-DQ8 (HLA-DRB104–DQA103:01–DQB1*03:02) has been identified as a major genetic […]
Introduction Human leukocyte antigen (HLA) genes play a pivotal role in the regulation of immune responses and susceptibility to autoimmune diseases. Among the most well-characterized HLA haplotypes, DR3-DQ2 (HLA-DRB103:01–DQA105:01–DQB1*02:01) stands out due to its strong association with a wide range of autoimmune […]
