We found that the expression of the anti-inflammatory cytokine, Tgf-β, which is known to play a beneficial role in DSS-induced colitis (24), was slightly upregulated when the mice were challenged with DSS; however, we did not observe a significant difference between the LysMCre+/−/Il-6rfl/fl mice and their littermate controls. Here, TGFB1 is linked to colitis.
