IL6 and colitis: The data showed that the induction of colitis using TNBS induced an increase in the expression of pro-inflammatory genes such as Tnf-α, Inf-γ, Il-1β, and Il-6 (Figure 1G) and, on the other hand, a reduction in the expression of anti-inflammatory cytokines such as Il-10 and Tgf-β (Figure 1H).
