CD4 and diffuse large B-cell lymphoma: To identify miRNAs associated with the reduced CD4+ T cell enrichment observed in HBV+ DLBCL, we analyzed the miRNA microarray data from HBx‐overexpressing SUDHL‐4 cells, identifying 78 differentially expressed miRNAs (44 up‐regulated, 34 down‐regulated), including HBx‐regulated miRNAs such as miR‐19a‐3p, miR‐486‐5p, and miR‐3960 (Figure 2A).
