Summary:
In a new study researchers identified what appears to be the first antibody-derived peptide that inhibits the activities of harmful microbes such as influenza A virus and HIV-1.

In a new study researchers identified what appears to be the first antibody-derived peptide that inhibits the activities of harmful microbes such as influenza A virus and HIV-1.

Influenza A viruses continue to result in hospitalization and death, especially among infants, the elderly, and immunocompromised patients worlwide. The emergence of avian influenza A virus and its ability to transfer to humans has brought about new concerns of a pandemic outbreak. Although vaccination can be an effective strategy for preventing influenza, researchers are also placing great emphasis on the discovery and development of antiviral drugs.

A killer decapeptide (KP) represents the internal image of a yeast (Pichia anomala) killer toxin that has an antimicrobial effect against pathogenic organisms. In the study activities of a KP against influenza A virus were evaluated and results showed that KP demonstrated a significant inhibitory effect on the replication of two strains of influenza A virus. Further, mice infected with influenza virus A were inoculated with KP once a day for ten days resulting in an improved survival rate of 40% and significantly decreased viral levels in their lungs.

"Overall, KP appears to be the first anti-idiotypic antibody-derived peptide that displays inhibitory activity and that has a potential therapeutic effect against pathogenic microorganisms, HIV-1, and influenza A virus by different mechanisms of action," say the researchers.
