HIV-1–Specific Immunodominant T-Cell Responses Drive the Dynamics of HIV-1 Recombination Following Superinfection

open access: yesFrontiers in Immunology, 2022
A series of HIV-1 CRF01_AE/CRF07_BC recombinants were previously found to have emerged gradually in a superinfected patient (patient LNA819). However, the extent to which T-cell responses influenced the development of these recombinants after ...

Evidence of differential HLA class I-mediated viral evolution in functional and accessory/regulatory genes of HIV-1. [PDF]

open access: yesPLoS Pathogens, 2007
Despite the formidable mutational capacity and sequence diversity of HIV-1, evidence suggests that viral evolution in response to specific selective pressures follows generally predictable mutational pathways.

Formation of a Unique Cluster of G-Quadruplex Structures in the HIV-1 nef Coding Region: Implications for Antiviral Activity [PDF]

open access: yes, 2013
G-quadruplexes are tetraplex structures of nucleic acids that can form in G-rich sequences. Their presence and functional role have been established in telomeres, oncogene promoters and coding regions of the human chromosome.

HIV-1 Nef mediates caspase activation for viral release.

open access: yes, 2023
(A) RNAseq analyses for differential gene expression on highlighted gene groups responsible for the cellular signaling pathways leading to caspase activation and apoptosis. RNA sequencing were performed using day 6 Nef+ and Nef- HIV-1NL4-3 infected CD4 T

Nef does not contribute to replication differences between R5 pre-AIDS and AIDS HIV-1 clones from patient ACH142

open access: yesRetrovirology, 2008
AIDS-associated, CCR5-tropic (R5) HIV-1 clones, isolated from a patient that never developed CXCR4-tropic HIV-1, replicate to a greater extent and cause greater cytopathic effects than R5 HIV-1 clones isolated before the onset of AIDS.

Overexpression of lncRNA‐NEF regulates the miR‐155/PTEN axis to inhibit adipogenesis and promote osteogenesis

open access: yesKaohsiung Journal of Medical Sciences, 2021
Osteoporosis is characterized by osteopenia and bone tissue microstructure degradation. Adipose‐derived stem cells (ADSCs) are multipotent adult stem cells that have the ability to yield mesenchymal stem cells and have the potential to undergo ...

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

open access: yesMedical 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]

open access: yesPLoS 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

open access: yesJournal 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:

Characterization of the Cutaneous Exanthem in Macaques Infected with a Nef Gene Variant of SIVmac239 [PDF]

open access: yesJournal of Investigative Dermatology, 1998
The molecularly cloned viruses known as SIVmac239/R17Y and SIVmac239/YEnef cause extensive lymphocyte activation and induce an acute disease syndrome in macaque monkeys. One manifestation of this syndrome is a severe diffuse cutaneous maculopapular exanthem that is similar to the exanthem associated with HIV-1 infection.
