TP4 (Nile tilapia piscidin)

TP4 (Nile tilapia piscidin) is an orally active piscidin-like antimicrobial peptide. TP4 inhibits multiple gram positive and negative strains (MIC: 0.03-10 μg/mL) . TP4 shows hemolytic activities. TP4 enhances immune response, antioxidant activity, and intestinal health against bacterial infections. TP4 also has anti-tumor effect, and induces necrosis by triggering mitochondrial dysfunction in cancer cells[1][2][3].
