Novel oral adjuvant to enhance cytotoxic memory like NK cell responses in HIV vaccine platform.
NPJ Vaccines
January 2025
Department of Microbial Infection and Immunity, College of Medicine, The Ohio State University, Columbus, OH, USA.
Natural killer (NK) cell-driven effector mechanisms, such as antibody-dependent cell-mediated cytotoxicity, emerged as a secondary correlate of protection in the RV144 HIV vaccine clinical trial, the only vaccine thus far demonstrating some efficacy in human trials. Therefore, leveraging NK cells with enhanced cytotoxic effector responses may bolster vaccine-induced protection against HIV. Here, we investigated the effect of orally administering indole-3-carbinol (I3C), an aryl hydrocarbon receptor (AHR) agonist, as an adjuvant to an RV144-like vaccine platform in a mouse model.

Objective: To identify demographic, social, and clinical factors associated with HIV self-management and evaluate whether the CHAMPS intervention is associated with changes in an individual's HIV self-management.
Method: This study was a secondary data analysis from a randomized controlled trial evaluating the effects of the CHAMPS, a mHealth intervention with community health worker sessions, on HIV self-management in New York City (NYC) and Birmingham. Group comparisons and linear regression analyses identified demographic, social, and clinical factors associated with HIV self-management.
Systematic Review on Chemsex: Advocating for Inclusive Research and Primary Prevention.

Chemsex is a specific practice of sexualized drug use (SDU), linked mainly to the group of men who have sex with men (MSM). This practice has become a public health problem due to the increase in sexually transmitted infections and HIV. However, there are groups and aspects that require greater visibility and research.

In recent years, plasma medicine has developed rapidly as a new interdisciplinary discipline. However, the key mechanisms of interactions between cold atmospheric plasma (CAP) and biological tissue are still in the exploration stage. In this study, by introducing the reactive molecular dynamics (MD) simulation, the capsid protein (CA) molecule of HIV was selected as the model to investigate the reaction process upon impact by reactive oxygen species (ROS) from CAP and protein molecules at the atomic level.

Background: The broad use of bedaquiline and pretomanid as the mainstay of new regimens to combat tuberculosis is a risk due to increasing bedaquiline resistance. We aimed to assess the safety, bactericidal activity, and pharmacokinetics of BTZ-043, a first-in-class DprE1 inhibitor with strong bactericidal activity in murine models.
Methods: This open-label, dose-expansion, randomised, controlled, phase 1b/2a trial was conducted in two specialised tuberculosis sites in Cape Town, South Africa.
