The human immunodeficiency virus type 1 (HIV) eradication will require elimination of HIV infected cells. No antiretroviral treatments (ART) or vaccine approaches have been able to reduce significantly the level of HIV infected cells in peripheral blood. This inefficacy is generally explained by the presence of a major reservoir of latent HIV infected cells in the central nervous system (CNS) that would be a sanctuary where C Read More

In the current study we investigated the prevalence of the TNF-α 238G/A single nucleotide polymorphism (SNP) of the TNF-α gene in the development of lipodystrophy among HIV-1 infected individuals who had been receiving antiretroviral therapy (ART) in the immunodeficiency clinics of the National AIDS Research Institute (NARI) at Pune, India. We assessed the association of this SNP with the development of lipoatrop Read More

Objectives: We evaluated an In-house assay for HIV-1 drug resistance genotyping by using DBS samples in China. Methods: The amplification sensitivity was assessed using 79 DBS specimens with plasma viral load ranging from 1,000 to 6,000 copies/ml. Precision was assessed using 5 DBS specimens with 5 replicates tested in one test run. Reproducibility was evaluated using other 5 DBS specimens with 5 replicates genotyp Read More

The existence of an HIV-1 protein translated from an antisense transcript was suggested over 25 years ago. However, this Antisense Protein (ASP) gene has still not been completely accepted by the HIV-1 research community. The aim of this review is to discuss recent findings, which suggest that ASP needs to be considered as a viral gene, playing an important role in HIV-1 replication and persistence. In past years, several stu Read More

Here we review the prevalence of HIV-1 primary drug resistance in Latin America and Caribbean using meta-analysis as well as time-series modeling. We also discuss whether there could be a drawback to HIV/AIDS programs due to drug resistance in Latin America and Caribbean in the next years. We observed that, although some studies report low or moderate primary drug resistance prevalence in Caribbean countrie Read More

Oxidative stress is a condition characterized by the imbalance between the production of reactive species (RS) or free radicals and their neutralization by the antioxidant defenses, leading to the accumulation of RS and their derived metabolites, with changes in the redox status of the cell. These RS can act on biological components and induce the oxidative and nitrosative reactions on lipids, proteins, and DNA. In this c Read More

Co-signaling molecules have been demonstrated to regulate regulatory T cells’ (Tregs) function during human immunodeficiency virus (HIV) infection. A recently reported co-signaling molecule called herpes virus entry mediator (HVEM), a member of the tumor necrosis factor receptor family, can both enhance and inhibit the immune response. HVEM was also reported to enhance the suppressive function of regulatory Read More

The emergence of drug resistance among HIV-positive patients undergoing Anti- Retroviral Therapy (ART) with poor adherence to the HAART is a major concern in India. As the HIV accumulates the key mutations, the drug resistance occurs, that pose challenges to the ART regimens currently being used. Thus, the present study was carried out among the ART- naïve patients attending ART Centre at Salem district, Tamil Nadu, I Read More
