HIV particles in the blood largely originate from activated lymphocytes and can overshadow
variants which may be expressed from other cell types. Investigations of virus persistence�…

Background Virus-associated cell membrane proteins acquired by HIV-1 during budding
may give information on the cellular source of circulating virions. In the present study, by�…

The incorporation of biologically active host proteins into HIV-1 is a well-established
phenomenon, particularly due to the budding mechanism of viral egress in which viruses�…

HIV-1 incorporates a large array of host proteins into virions. Determining the host protein
composition in HIV virions has technical difficulties, including copurification of microvesicles�…

Antigens derived from host cells are detectable in the envelope of human immunodeficiency
virus type 1 (HIV-1) and result in a distinctive viral phenotype reflecting that of the host cell�…

HIV-1 acquires cell membrane proteins during budding. The cell membrane proteins (CMP)
profile of laboratory HIV-1 strains grown in different host cells was established, by using an�…

Incorporation of cellular proteins into the HIV-1 envelope upon viral budding has been well
documented, and specific inclusion or exclusion of host molecules has been proposed [1]�…

HIV-1 assembly and release are believed to occur at the plasma membrane in most host
cells with the exception of primary macrophages, for which exclusive budding at late�…

Objective: To determine the acquisition of host cell-membrane-derived molecules by HIV-1
during the budding process, and to investigate whether the uptake of these molecules is cell�…

In vitro, dendritic cells (DCs) bind and transfer intact, infectious HIV to CD4 T cells without
first becoming infected, a process known as trans-infection. trans-infection is accomplished�…
