Activité biologique
Lactoferrin 17-41 (Lactoferricin B) has an MIC of 30 μg/ml against E. coli ATCC 25922[1].
Lactoferrin 17-41 significantly stimulates apoptosis of HT-29 cells and displays cytotoxic activity on HT-29 cells[2].
Lactoferrin 17-41 variously regulats transcription of genes involved in the p53 signaling pathway, such as PMAIP-1, TP5313, and SFN[2].
Lactoferrin 17-41 can bind LPS from Gram-negative bacteria and that it can inhibit LPS induced cytokine response in human monocytic cells[1][3].
