Cutaneous defense mechanisms by antimicrobial peptides.
The skin actively contributes to host defense by mounting an innate immune response that includes the production of antimicrobial peptides. These peptides, which include but are not limited to the cathelicidin and defensin gene families, provide rapid, broad-spectrum defense against infection by acting as natural antibiotics and by participating in host cell processes involved in immune defense...
متن کاملAntimicrobial RNases in cutaneous defense.
Antimicrobial proteins (AMP) are small endogenous proteins which are capable of rapidly inactivating microorganisms at low micro- and nanomolar concentrations. Their significance in host defense is reflected by their wide distribution in nature. Several AMP have been isolated from human skin, and there is increasing evidence that AMP may play an important role in cutaneous defense. One importan...
متن کاملCationic host defense (antimicrobial) peptides.
Members of the cationic host defense (antimicrobial) peptide family are widely distributed in nature, existing in organisms from insects to plants to mammals and non-mammalian vertebrates. Although many demonstrate direct antimicrobial activity against bacteria, fungi, eukaryotic parasites and/or viruses, it has been established that cationic peptides have a key modulatory role in the innate im...
متن کاملIntracellular Targeting Mechanisms by Antimicrobial Peptides.
Antimicrobial peptides (AMPs) are expressed in various living organisms as first-line host defenses against potential harmful encounters in their surroundings. AMPs are short polycationic peptides exhibiting various antimicrobial activities. The principal antibacterial activity is attributed to the membrane-lytic mechanism which directly interferes with the integrity of the bacterial cell membr...
متن کاملImmune modulation by multifaceted cationic host defense (antimicrobial) peptides.
Cationic host defense (antimicrobial) peptides were originally studied for their direct antimicrobial activities. They have since been found to exhibit multifaceted immunomodulatory activities, including profound anti-infective and selective anti-inflammatory properties, as well as adjuvant and wound-healing activities in animal models. These biological properties suggest that host defense pept...
