Abstract
The replication of human immunodeficiency virus type 1 (HIV-1) in non-dividing cells, such as terminally differentiated macrophages, critically depends on the import of the viral pre-integration complex (PIC) into the nucleus. Vpr, one of the accessory gene products of HIV-1, plays a key regulatory role in PIC nuclear import in macrophages, although its role in the PIC entry mechanism remains to be clarified. Here, we summarize what is currently known about the nuclear- entry step of HIV-1 replication, mainly focusing on how Vpr functions as the main regulator of HIV-1 nuclear import and how it could facilitate the development of novel inhibitors of this process.

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
