HLA allele

HLA (Human Leukocyte Antigen) alleles are specific variations of genes that help our immune system distinguish between the body's own cells and foreign invaders like viruses or bacteria. These genes are part of a complex system called the HLA system, which plays a crucial role in immune response and tissue compatibility. Each person inherits a unique set of HLA alleles, making them important for tissue transplants and understanding immune-related diseases. Variations in HLA alleles can influence how the immune system reacts and are key to personalized medicine approaches.
