To evaluate the antimicrobial and antiviral activities of alpha-melanocyte-stimulating hormone (alpha-MSH) and characterize its role in innate host defense.
Tested alpha-MSH and its peptide fragment KPV in vitro against the bacterium Staphylococcus aureus and the yeast Candida albicans.
Treated acutely and chronically HIV-infected human monocytes with alpha-MSH to assess viral replication and monitored NF-kappa B transcription factor activation.
Alpha-MSH and the KPV fragment exhibited direct inhibitory actions against both Staphylococcus aureus and Candida albicans.
Treatment with alpha-MSH reduced HIV replication in both acutely and chronically infected human monocytes.
Molecular assays revealed that alpha-MSH inhibited the activation of the transcription factor NF-kappa B.
