Antimicrobial defensin peptides of the human ocular surface.
BACKGROUND/AIMS The antimicrobial activity of the tear film exceeds the activity of its known constituents. The authors postulate that this excess activity is the result of antimicrobial peptides called defensins, and they aimed to look for defensins in the human eye. METHODS Evidence of defensin production was sought by reverse transcriptase polymerase chain reaction (RT-PCR). Intron spannin...
متن کاملThe role of antimicrobial peptides at the ocular surface.
Antimicrobial peptides (AMPs) such as defensins and cathelicidins are small peptides with broad-spectrum activity against bacteria, fungi and viruses. In addition, several AMPs modulate mammalian cell behaviours including migration, proliferation and cytokine production. This review describes findings from recent studies showing the presence of various AMPs at the human ocular surface and discu...
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 کاملSynergistic interactions between mammalian antimicrobial defense peptides.
A single animal can express several cationic antimicrobial peptides with different sequences and structures. We demonstrate that mammalian peptides from different structural classes frequently show synergy with each other and selectively show synergy with human lysozyme.
متن کاملCutaneous 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...
