activated CD4 T cells(P=0.016),resting NK cells(P<0.001),M0 macrophages(P<0.001),M2 macrophages(P<0.001),eosinophils(P<0.001),and
neutrophils(P<0.001)were observed in the CLEC5A high expression group compared with the low expression group(n=375). C:The proportions of
different TILs subpopulations were moderately correlated(n=375).
