Periplanetasine-4

Periplanetasin-4 is an antimicrobial peptide that can be derived from the American cockroach (Periplaneta americana) . Periplanetasin-4 reduces cell rounding and apoptosis. Periplanetasin-4 blocks Clostridium difficile toxin A-induced ROS production and the activation of downstream p38 MAPK and p21. Periplanetasin-4 significantly increases mitochondrial calcium level, reduces DPH fluorescence intensity and vacuolar dysfunction in Candida albicans ATCC 90028 cells. Periplanetasin-4 significantly ameliorates toxin A-induced mucosal damage in the mouse gut. Periplanetasin-4 can be used for the study of colitis[1][2].
