Human Leukocyte Antigen A*02

Molecular classification
Class I MHC, Receptor
01

Overview

HLA-A*02 is a specific allele group within the HLA-A locus, a class I MHC molecule, that presents endogenous peptides to CD8+ T cells. It plays a crucial role in immune surveillance and is implicated in various diseases, including infections, autoimmune disorders, and cancer. Specific variants, such as HLA-A*02:01, are frequently referenced in clinical contexts, including transplantation and cancer immunotherapy.
