چکیده

Prior work has shown that the HIV-1 envelope of the human immunodeficiency virus (HIV) interacts directly with T-cell immunoglobulin mucin (TIM) family proteins. Herein, we demonstrate that HIV-1 envelope glycoproteins from varying HIV-1 clades bind differentially to TIM proteins and functionally similar proteins acting as phosphatidylserine (PtdSer) receptors. Using enzyme-linked immunosorbent assay (ELISA) and surface plasmon resonance (SPR) technology, we show that lysate containing HIV-1 envelope and recombinant HIV-1 envelope glycoproteins bind TIM-4 and advanced glycosylation end product-specific receptor (AGER). The complex binding of HIV-1 UG21 gp140 to TIM-4 or AGER suggests a biphasic interaction with these proteins.

Role of phosphatidylserine receptors in enveloped virus infection.

UNLABELLED We recently demonstrated that a soluble protein, Gas6, can facilitate viral entry by bridging viral envelope phosphatidylserine to Axl, a receptor tyrosine kinase expressed on target cells. The interaction between phosphatidylserine, Gas6, and Axl was originally shown to be a molecular mechanism through which phagocytes recognize phosphatidylserine exposed on dead cells. Since our in...

Fusion Stage of HIV-1 Entry Depends on Virus-Induced Cell Surface Exposure of Phosphatidylserine.

HIV-1 entry into host cells starts with interactions between the viral envelope glycoprotein (Env) and cellular CD4 receptors and coreceptors. Previous work has suggested that efficient HIV entry also depends on intracellular signaling, but this remains controversial. Here we report that formation of the pre-fusion Env-CD4-coreceptor complexes triggers non-apoptotic cell surface exposure of the...

HIV and the chemokine system: 10 years later.

The unexpected encounter, 10 years ago, between human immunodeficiency virus (HIV) and the chemokine system has dramatically advanced our understanding of the pathogenesis of AIDS, opening new perspectives for the development of effective prophylactic and therapeutic measures. To initiate infection, the HIV-1 external envelope glycoprotein, gp120, sequentially interacts with two cellular recept...

Differential glycosylation of envelope gp120 is associated with differential recognition of HIV-1 by virus-specific antibodies and cell infection

BACKGROUND HIV-1 entry into host cells is mediated by interactions between the virus envelope glycoprotein (gp120/gp41) and host-cell receptors. N-glycans represent approximately 50% of the molecular mass of gp120 and serve as potential antigenic determinants and/or as a shield against immune recognition. We previously reported that N-glycosylation of recombinant gp120 varied, depending on the ...
