As shown in Figure 4B, Ma.24 infection caused the down‐regulation of IL‐10 which was further decreased by HMGN2 knock‐down in macrophages, while we observed that there is no obvious influence by Ma.24 infection and HMGN2 knock‐down on TGF‐β expression in macrophage. This evidence concerns the gene TGFB1 and infection.
