Abstract

Human milk contains numerous endogenous polypeptides cleaved from specific proteins.They are produced by the complex proteolytic systems (zymogens,active protease,protease inhibitors and activators) which are originated in blood,mammary epithelial cells and immune cells.Due to the congenital deficiency as well as the differences of protein expression and enzyme activation in premature infants,it contains a significantly greater proportion of the endogenous polypeptides in the preterm milk by contrast with the term milk.This article reviews the current researches of the proteolytic systems in human milk.

Key words

human milk / protease / endogenous polypeptides / mammary epithelial cell
