CD64, CD32, CD16, CD163 and CD86 are homologous leucocyte differentiation antigens that are able to activate T‐cell proliferation through antigen‐antibody reactions.29 Studies have also shown that CD86 and CD163 have a significant correlation with the proliferation and progression of GC.30 LCP2,31 CSF1R,32 LILRB233 and TLR834 both interact with T lymphocytes in tumour immune regulation and affect tumour prognosis. Here, FCGR2A is linked to neoplasm.
