Abstract
Conserved in all primate lentivirus genomes, Nef promotes viral replication and infectivity, influences the trafficking of a large number of surface receptors and interferes with TCR signalling, consequently modulating T-cell activation. In vivo observations with Long Term Non-Progressors harbouring a Nef-defective HIV and vaccination studies with Nef-deleted SIV in Rhesus macaques have shown a prominent role for Nef in lentiviral pathogenesis. Here we review the functions of Nef involved in viral replication and infectivity and speculate on a possible role for Nef in HIV fitness.

HIV vaccine development
The development of a safe and effective vaccine that impedes HIV-1 transmission and/or limits the severity of infection remains a public health priority. The HIV-1/AIDS pandemic continues to have a disproportionate impact on vulnerable and under-served communities in the USA and globally. In the USA, minority communities that have relatively ...read more
Lymphomas in people living with HIV (PLWH)
In the era of combined antiretroviral therapy (cART), the incidence of lymphoma among people living with HIV (PLWH) surpassed Kaposi's sarcoma in 2011, becoming the most common AIDS-defining malignancy. The annual incidence rate ranges approximately from 100 to 300 per 100,000 individuals with HIV infection as the population denominator, which ...read more
