Preclinical evidence suggests that related LAB strains can attenuate NF-κB, MAPK, STAT3, IL-17, and COX-2-associated inflammatory pathways, reduce immune-cell infiltration and oxidative stress, restore mucus and tight junction proteins, modulate bile acid metabolism, and reduce tumor burden in CRC or colitis-associated CRC models. The gene discussed is IL17A; the disease is colorectal carcinoma.
