Abstract
To export intron-containing viral mRNAs that encode the structural components of new viral particles from the nucleus to the cytoplasm, HIV-1 uses the cellular CRM1 export pathway that is exploited by the viral Rev protein. Rev multimerizes on the Rev response element (RRE) present in the intron-containing RNA species to bridge these to the cellular export factor CRM1. As a result, this Rev-RRE complex is exported to the cytoplasm. This review provides a systematic overview of different aspects of the crucial function of Rev multimerization, such as co-operative Rev-Rev and Rev-RNA interactions, the biological function of Rev multimerization, the relevance of Rev multimerization in the absence of RRE and its potential as a therapeutic target.

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
