Similarly, TGR5 activation elevates intracellular cAMP levels, leading to downstream activation of protein kinase A (PKA) and exchange protein directly activated by cAMP (Epac), which suppresses NF-B signaling, inhibits NLRP3 inflammasome activation, and can promote macrophage polarization from the pro-inflammatory M1 phenotype toward the anti-inflammatory M2 phenotype 148
