Other significantly elevated populations of B cells in HIV+ pre-NHL (cART-naïve) were CD20+CXCR4+CXCR5-IgM+HLA-DR+ B cells (MC37); CD20+CD27-CXCR4+CXCR5-IgM+HLA-DR+ B cells (MC39); CD20+CD27+CD10+CD24+CXCR4+IgM+HLA-DR+ memory B cells expressing cMYC (MC47); CD20+CD27+CD24+CXCR4+CXCR5+ B cells (MC44); and CD20+CD27-CD24+CXCR4+CXCR5+ B cells (MC48) (Figure 3C and Supplementary Table 4). Here, CD27 is linked to non-Hodgkin lymphoma.
