Antimicrobial peptides in innate intestinal host defence.
Precursors of alpha-defensin peptides require activation for bactericidal activity. In mouse small intestine, matrilysin colocalized with alpha-defensins (cryptdins) in Paneth cell granules, and in vitro it cleaved the pro segment from cryptdin precursors. Matrilysin-deficient (MAT−/−) mice lacked mature cryptdins and accumulated precursor molecules. Intestinal peptide preparations from MAT−/− ...
متن کاملA re-evaluation of the role of host defence peptides in mammalian immunity.
Host defence peptides are found in all classes of life and are a fundamental component of the innate immune response. Initially it was believed that their sole role in innate immunity was to kill invading microorganisms, thus providing direct defence against infection. Evidence now suggests that these peptides play diverse and complex roles in the immune response and that, in higher animals, th...
متن کاملFunction and therapeutic potential of host defence peptides.
Cationic host defence (antimicrobial) peptides are an important component of the innate immune systems of a wide variety of plants, animals, and bacteria. Although most of these compounds have direct antimicrobial activities under specific conditions, a greater appreciation for the diversity of functions of these molecules is beginning to develop in the field. In addition to their directly anti...
متن کاملCationic host defence peptides: multifaceted role in immune modulation and inflammation.
Host defence peptides (HDPs) are innate immune effector molecules found in diverse species. HDPs exhibit a wide range of functions ranging from direct antimicrobial properties to immunomodulatory effects. Research in the last decade has demonstrated that HDPs are critical effectors of both innate and adaptive immunity. Various studies have hypothesized that the antimicrobial property of certain...
متن کاملAnti-endotoxin properties of cationic host defence peptides and proteins.
The innate immune system of mammals contains a series of peptides with overall positive charge and an amphipathic structure which have a variety of important properties in host defences. Although these are often termed cationic antimicrobial peptides, they have numerous roles in innate defences in all complex species of life and thus we prefer to refer to them as host defence peptides. These ro...
