Nicotinamide activates latent HIV-1 ex vivo in ART suppressed individuals, revealing higher potency than the association of two methyltransferase inhibitors, chaetocin and BIX01294

Braz. j. infect. dis; 24 (2), 2020
ABSTRACT Background: Latent HIV-1 is a major hurdle in obtaining HIV-1 sustained virological remission (SVR). Here we explored histone deacetylation inhibition property of nicotinamide (NAM; n = 17) for the first time in comparison to a combination of methyltransferase inhibitors (MTIs; Chaetocin and BI...

Polyomaviruses BK and JC DNA infection in peripheral blood cells from blood donors

Braz. j. infect. dis; 23 (1), 2019
ABSTRACT Objectives: To investigate the prevalence of human polyomavirus (BK and JC viruses) infection in peripheral blood mononuclear cells of healthy blood donors. Methods: The study included 250 healthy blood donors. Five-milliliter blood was drawn into sterile EDTA tubes and PBMCs were isolated fro...

Evaluation of the cervicovaginal environment in asymptomatic Human T-cell lymphotropic virus type 1 infected women

Braz. j. infect. dis; 23 (1), 2019
ABSTRACT Introduction: Human T-cell lymphotropic virus type 1 (HTLV-1) is sexually transmitted and causes persistent infection. This virus induces activation of the immune system and production of inflammatory cytokines. This study aimed to assess the cytokine profile and cytopathological findings in th...

Evaluating the use of fluorescence-based flow cytometry assay for dengue diagnosis using peripheral blood mononuclear cells

Abstract INTRODUCTION: Dengue virus (DENV) is the most important arthropod-borne viral disease worldwide with an estimated 50 million infections occurring each year. METHODS: In this study, we present a flow cytometry assay (FACS) for diagnosing DENV, and compare its results with those of the non-str...

Epstein-Barr virus load in transplant patients: Early detection of post-transplant lymphoproliferative disorders

Rev. argent. microbiol; 48 (2), 2016
High levels of circulating EBV load are used as a marker of post-transplant lymphoproliferative disorders (PTLD). There is no consensus regarding the threshold level indicative of an increase in peripheral EBV DNA. The aim of the study was to clinically validate a developed EBV quantification assay for e...

Estudo da infecçäo pelo HIV-1 na Bahia: determinaçäo da carga viral, características genotípicas e associaçäo com HTLV-I/II

O conhecimento sobre os mecanismos patogênicos e sobre a cinética da infecçäo pelo virus da imunodeficiência humana levou à rápida expansäo do conjunto de informaçöes acumuladas sobre HIV-1, no curto espaço de tempo que separou a eclosäo dos primeiros casos registrados do momento atual, quand...
