1 Dasatinib inhibits HIV-1 replication through the interference of SAMHD1 phosphorylation in CD4+ T cells. Dasatinib SAM and HD domain containing deoxynucleoside triphosphate triphosphohydrolase 1 Homo sapiens
2 We demonstrate that Dasatinib can actually interfere with SAMHD1 phosphorylation in human peripheral blood lymphocytes, preserving its antiviral activity against HIV-1. Dasatinib SAM and HD domain containing deoxynucleoside triphosphate triphosphohydrolase 1 Homo sapiens
3 Dasatinib prevented SAMHD1 phosphorylation in vitro and ex vivo, impairing HIV-1 reverse transcription and proviral integration. Dasatinib SAM and HD domain containing deoxynucleoside triphosphate triphosphohydrolase 1 Homo sapiens
4 This was the major mechanism of action because the presence of Vpx, which degrades SAMHD1, in HIV-1 virions impeded the inhibitory effect of Dasatinib on HIV-1 replication. Dasatinib SAM and HD domain containing deoxynucleoside triphosphate triphosphohydrolase 1 Homo sapiens
5 Finally, PBMCs from patients on chronic treatment with Dasatinib showed a lower level of SAMHD1 phosphorylation in response to activating stimuli and low susceptibility to HIV-1 infection ex vivo. Dasatinib SAM and HD domain containing deoxynucleoside triphosphate triphosphohydrolase 1 Homo sapiens
6 Consequently, Dasatinib is a compound currently used in clinic that preserves the antiviral function of SAMHD1. Dasatinib SAM and HD domain containing deoxynucleoside triphosphate triphosphohydrolase 1 Homo sapiens
