However, the expression of these antigens typically fails to result in the efficient eradication of tumour cells, attributed to various factors, including inconsistent antigen expression, immunological tolerance, low affinity between the T‐cell receptor (TCR) and the major histocompatibility complex (MHC)/peptide complex, as well as the presence of an immunosuppressive microenvironment.5 Here, HLA-C is linked to neoplasm.
