Especially in DLBCL, CD1c expression was positively correlated with B cells, neutrophils, dendritic cells and negatively associated with CD8+ T cells, CD4+ T cells, and macrophages, among which, the correlation with B cells was the highest (cor = 0.693, P = 1.44E−03, Fig. 7B). This evidence concerns the gene CD4 and diffuse large B-cell lymphoma.
