HLA-DQB1 and diffuse large B-cell lymphoma: The relationship between FOXP1 and individual MHC II genes was further evaluated within GCB (n=183) or ABC (n=167) molecularly defined DLBCL subtypes: FOXP1 displayed significant inverse relationships (r<−0.15; P<0.05) with HLA-DRA, HLA-DMB and HLA-DQB1 in both DLBCL subtypes (Figure 4c).
