Nef gene evolution from a single transmitted strain in acute SIV infection [PDF]

Retrovirology, 2009
Abstract Background The acute phase of immunodeficiency virus infection plays a crucial role in determining steady-state virus load and subsequent progression of disease in both humans and nonhuman primates. The acute period is also the time when vaccine-mediated effects on host immunity are likely to exert their ...

Alzheimer's disease and HIV associated dementia related genes: I. location and function. [PDF]

, 2008
Alzheimer's disease (AD), the most common cause of dementia, has few clinical similarities to HIV-1-associated dementia (HAD). However, genes were identified related among these dementias.

Construction of a Prokaryotic Expression Vector harboring Two HIV-1 Accessory Genes

Medical Laboratory Journal, 2021
Background and objectives: HIV-1 Nef and Vpr antigens have been described as suitable candidates for therapeutic HIV vaccine development. The aim of this study was to generate Nef-Vpr fusion gene construct and to clone the construct into pET-23a (+), a ...

Comparison of HIV-1 nef and gag Variations and Host HLA Characteristics as Determinants of Disease Progression among HIV-1 Vertically Infected Kenyan Children. [PDF]

PLoS ONE, 2015
Disease progression varies among HIV-1-infected individuals. The present study aimed to explore possible viral and host factors affecting disease progression in HIV-1-infected children.Since 2000, 102 HIV-1 vertically-infected children have been followed-

The frequency of defective genes in vif and vpr genes in 20 hemophiliacs is associated with Korean Red Ginseng and highly active antiretroviral therapy: the impact of lethal mutations in vif and vpr genes on HIV-1 evolution

Journal of Ginseng Research, 2021
Background: We have reported that internal deletions in the nef, gag, and pol genes in HIV-1–infected patients are induced in those treated with Korean Red Ginseng (KRG). KRG delays the development of resistance mutations to antiretroviral drugs. Methods:

HIV-1 Genes vpr and nef Synergistically Damage Podocytes, Leading to Glomerulosclerosis [PDF]

Journal of the American Society of Nephrology, 2006
This study aimed to identify the causative gene for HIV-1 associated nephropathy, a paradigmatic podocytopathy. A previous study demonstrated that transgenic expression of nonstructural HIV-1 genes selectively in podocytes in mice with FVB/N genetic background resulted in podocyte injury and glomerulosclerosis.

Nucleolar Localization of HIV-1 Rev Is Required, Yet Insufficient for Production of Infectious Viral Particles. [PDF]

, 2018
Combination antiretroviral therapy fails in complete suppression of HIV-1 due to drug resistance and persistent latency. Novel therapeutic intervention requires knowledge of intracellular pathways responsible for viral replication, specifically those ...

The Human Immunodeficiency Virus Type 1nefGene Can to a Large Extent Replace Simian Immunodeficiency VirusnefIn Vivo [PDF]

Journal of Virology, 1999
ABSTRACTThenefgene of the pathogenic simian immunodeficiency virus (SIV) 239 clone was replaced with primary human immunodeficiency virus type 1 (HIV-1)nefalleles to investigate whether HIV-1 Nef can substitute for SIV Nef in vivo. Initially, two rhesus macaques were infected with the chimeric viruses (Nef-SHIVs).

Relative Resistance of HLA-B to Downregulation by Naturally Occurring HIV-1 Nef Sequences

mBio, 2016
HIV-1 Nef binds to the cytoplasmic region of HLA-A and HLA-B and downregulates these molecules from the surface of virus-infected cells, thus evading immune detection by CD8+ T cells.

Structural basis of HIV-1 Vpu-mediated BST2 antagonism via hijacking of the clathrin adaptor protein complex 1. [PDF]

, 2014
BST2/tetherin, an antiviral restriction factor, inhibits the release of enveloped viruses from the cell surface. Human immunodeficiency virus-1 (HIV-1) antagonizes BST2 through viral protein u (Vpu), which downregulates BST2 from the cell surface.
