Palbociclib, a selective inhibitor of cyclin-dependent kinase4/6, blocks HIV-1 reverse transcription through the control of sterile α motif and HD domain-containing protein-1 (SAMHD1) activity

Abstract

Our results indicate that SAMHD1-mediated HIV-1 restriction is controlled by CDK as previously suggested but point to a preferential role for CDK2 and CDK6 as mediators of SAMHD1 activation. Our study provides a new signaling pathway susceptible for the development of new therapeutic approaches against HIV-1 infection.
