Notably, the expression of inducible costimulatory molecules (ICOS) on CD4 + T cells is significantly increased in the inflammatory mucosa of IBD patients, and this overexpression promotes the production of inflammatory cytokines such as IL-5 in UC and IFN- in CD, suggesting that ICOS may serve as a potential therapeutic target for IBD [40]
Second, like all proteins neurotrophic factors are susceptible to degradation by proteases and hence require chronic dosing methods

Thus, the inhibition of p52 by metformin results in the ability of the PDE4B gene to remain transcriptionally active leading to reductions in the level of cAMP and reduced activation of PKA
