Common principles and intermediates of viral protein-mediated fusion: the HIV-1 paradigm (2008)

Melikyan, Gregory B

Abstract Enveloped viruses encode specialized fusion proteins which promote the merger of viral and cell membranes, permitting the cytosolic release of the viral cores. Understanding the molecular...

Imaging individual retroviral fusion events: From hemifusion to pore formation and growth

Melikyan, Gregory B., Barnard, Richard J. O., Abrahamyan, Levon G., Mothes, Walther, Young, John A. T.

Viral fusion proteins catalyze merger of viral and cell membranes through a series of steps that have not yet been well defined. To elucidate the mechanism of virus entry, we have imaged fusion...

Ternary Complex Formation of Human Immunodeficiency Virus Type 1 Env, CD4, and Chemokine Receptor Captured as an Intermediate of Membrane Fusion

Mkrtchyan, Samvel R., Markosyan, Ruben M., Eadon, Michael T., Moore, John P., Melikyan, Gregory B., Cohen, Fredric S.

Human immunodeficiency virus (HIV) Env-induced fusion is highly temperature dependent. When effector and target cells were coincubated at 37°C, there was a kinetic delay before fusion commenced....

Membrane-Anchored Inhibitory Peptides Capture Human Immunodeficiency Virus Type 1 gp41 Conformations That Engage the Target Membrane prior to Fusion

Melikyan, Gregory B., Egelhofer, Marc, Von Laer, Dorothee

Soluble peptides derived from the C-terminal heptad repeat domain of human immunodeficiency virus type 1 (HIV-1) gp41 are potent inhibitors of HIV-1 entry and gp41-induced fusion. Target...

Rapamycin Reduces CCR5 Density Levels on CD4 T Cells, and This Effect Results in Potentiation of Enfuvirtide (T-20) against R5 Strains of Human Immunodeficiency Virus Type 1 In Vitro▿

Heredia, Alonso, Gilliam, Bruce, Latinovic, Olga, Le, Nhut, Bamba, Douty, DeVico, Anthony, ...

The CCR5 chemokine receptor plays a pivotal role in human immunodeficiency virus type 1 (HIV-1) infection. Several studies have suggested that CCR5 density levels in individuals are rate limiting for...

Early Steps of HIV-1 Fusion Define the Sensitivity to Inhibitory Peptides That Block 6-Helix Bundle Formation

Miyauchi, Kosuke, Kozlov, Michael M., Melikyan, Gregory B.

The HIV envelope (Env) glycoprotein mediates membrane fusion through sequential interactions with CD4 and coreceptors, followed by the refolding of the transmembrane gp41 subunit into the stable...
