Abstract
RhoA-derived peptides have been shown to have antiviral activity against both human respiratory syncytial virus and human parainfluenza virus-3. The present study investigates the toxicity, anti-HIV-1 activity and mechanism of action of a RhoA-derived peptide (RhoA 77-95). The efficacy of this peptide was compared to a scrambled peptide of the same amino acid composition and Enfuvirtide, a HIV entry inhibitor. Our data show that this RhoA-derived peptide is a non-toxic and effective inhibitor of a CXCR4 tropic strain of HIV-1. We also demonstrate that the mechanism of entry inhibition is likely mediated by polyanionic properties and is dependent on the dimerization of peptides.

Management of HIV: Management of HIV: old challenges and new needs
The aim of this thematic issue is to provide the most recent updates regarding the effective management of HIV infection. Antiretroviral therapy (ART) has significantly decreased HIV-related mortality, leading to an enhancement in the quality of life and life expectancy for people living with HIV (PLWH). Despite the numerous advancements ...read more
