Novel peptides based on HIV-1 gp120 sequence with homology to chemokines inhibit HIV infection in cell culture.

PLoS ONE, 2011
The sequential interaction of the envelope glycoprotein of the human immunodeficiency virus type 1 (HIV-1) with CD4 and certain chemokine coreceptors initiates host cell entry of the virus.

Rescue of adult hippocampal neurogenesis in a mouse model of HIV neurologic disease

Neurobiology of Disease, 2011
The prevalence of central nervous system (CNS) neurologic dysfunction associated with human immunodeficiency virus (HIV) infection continues to increase, despite the use of antiretroviral therapy.

Binding of HIV-1 gp120 to DC-SIGN promotes ASK-1-dependent activation-induced apoptosis of human dendritic cells.

PLoS Pathogens, 2013
During disease progression to AIDS, HIV-1 infected individuals become increasingly immunosuppressed and susceptible to opportunistic infections. It has also been demonstrated that multiple subsets of dendritic cells (DC), including DC-SIGN⁺ cells, become

Effect of chloroquine on reducing HIV-1 replication in vitro and the DC-SIGN mediated transfer of virus to CD4⁺ T-lymphocytes

Retrovirology, 2007
Background Chloroquine (CQ) has been shown to inhibit HIV-1 replication in vitro as well as in vivo and has been proposed to alter the glycosylation pattern of the gp120 envelope.

Positive In Vivo Selection of the HIV‐1 Envelope Protein gp120 Occurs at Surface‐Exposed Regions [PDF]

The Journal of Infectious Diseases, 2007
The rapid evolution of human immunodeficiency virus (HIV) envelope represents a major challenge to vaccine and drug development, particularly because the underlying mechanisms are not completely understood. To explore whether distinct patterns of positive selection within the envelope glycoprotein (gp) 120 exist and are associated with functionally ...

M‐tropic HIV envelope protein gp120 exhibits a different neuropathological profile than T‐tropic gp120 in rat striatum [PDF]

European Journal of Neuroscience, 2010
AbstractMost early human immunodeficiency virus type 1 (HIV‐1) strains are macrophage (M)‐tropic HIV variants and use the chemokine receptor CCR5 for infection. Neuronal loss and dementia are less severe among individuals infected with M‐tropic strains.

Role of the transcription factor E2F1 in CXCR4-mediated neurotoxicity and HIV neuropathology

Neurobiology of Disease, 2007
This study sought to determine the role of the transcription factor E2F1 in CXCR4-mediated neurotoxicity and HIV neuropathology. We studied the effect of the HIV envelope protein gp120 on the expression of E2F1-dependent apoptotic proteins in human and ...

Generation and characterization of a bivalent protein boost for future clinical trials: HIV-1 subtypes CR01_AE and B gp120 antigens with a potent adjuvant. [PDF]

PLoS ONE, 2018
The RV144 Phase III clinical trial with ALVAC-HIV prime and AIDSVAX B/E subtypes CRF01_AE (A244) and B (MN) gp120 boost vaccine regime in Thailand provided a foundation for the future development of improved vaccine strategies that may afford protection ...
