Diagnosis, antiretroviral therapy, and emergence of resistance to antiretroviral agents in HIV-2 infection: a review

Brazilian Journal of Infectious Diseases
Human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2) are the causative agents of AIDS. HIV-2 is prevalent at moderate to high rates in West African countries, such as Senegal, Guinea, Gambia, and Cape Verde.

Computational Analysis of POL Gene of Human Immunodeficiency Virus Type 1 (HIV-1)

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2009
AIDS results from an infection with HIV-1 virus. It is a class of retrovirus whose genome contains the genes for reverse transcriptase. The gene that codes for reverse transcriptase in HIV-1 is the POL gene.

Canonical Antibodies Adopt Distinct Binding Modes to Recognize Viral Glycan Shields

Advanced Science, EarlyView.
Canonical Y‐shaped antibodies recognize viral glycan shields through adaptive Fab assembly states shaped by glycan organization and somatic hypermutation. Structural analyses ofbroadly neutralizing antibodies VRC35 and VRC36 across glycoproteins of HIV‐1, influenza, SARS‐CoV‐2, and Lassa viruses reveal distinct Fab assembly states, spanning monovalent,

A simple screening approach to reduce B*5701-associated abacavir hypersensitivity on the basis of sequence variation in HIV reverse transcriptase [PDF]

, 2007
Background. Abacavir hypersensitivity is strongly associated with the human leukocyte antigen (HLA)–B*5701 allele; however, the cost of routine high-resolution HLA typing before initiation of therapy remains prohibitive.

Impact of the N348I Mutation in HIV-1 Reverse Transcriptase on Nonnucleoside Reverse Transcriptase Inhibitor Resistance in Non-Subtype B HIV-1

, 2011
We investigated the effect of N348I alone and with M184V on nonnucleoside reverse transcriptase inhibitor (NNRTI) drug susceptibility and replicative capacity in B and non-B HIV-1 isolates.

Rapid enzymatic test for phenotypic HIV protease drug resistance [PDF]

, 2003
A phenotypic resistance test based on recombinant expression of the active HIV protease in E. coli from patient blood samples was developed. The protease is purified in a rapid onestep procedure as active enzyme and tested for inhibition by five selected

Engineering Stable Lentiviral Vector Producer Cells Improves LVV Production

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Stable lentiviral vector producer cell lines represent a promising platform for scalable and cost‐efficient vector manufacturing, yet their productivity is often limited by intrinsic host‐cell constraints. In this study, we aimed to identify cellular factors restricting LVV production in stable doxycycline‐inducible GPRTG producer cell lines ...

Pre-incubation of cell-free HIV-1 group M isolates with non-nucleoside reverse transcriptase inhibitors blocks subsequent viral replication in co-cultures of dendritic cells and T cells. [PDF]

, 2005
In order to study the inhibitory effect of various reverse transcriptase inhibitors (RTIs) on cell-free HIV, we adapted a recently described in vitro system, based on co-cultures of dendritic cells and resting CD4 T cells, modelling early target cells ...
