HIV uses the immune system’s own tools to suppress it

A Canadian research team at the IRCM in Montréal, led by molecular virologist Éric A. Cohen, PhD, made a significant discovery on how HIV escapes the body’s antiviral responses. The team uncovered how an HIV viral protein known as Vpu tricks the immune system by using its own regulatory process to evade the host’s first line of defence. This breakthrough was published yesterday in the scientific journal PLoS Pathogens and will be presented at the upcoming IAS 2015 conference in Vancouver. The findings pave the way for future HIV prevention or cure strategies.

Impact of video gaming on the brain

A new study published in the journal Proceedings of the Royal Society B by the teams of Dr. Gregory West (Assistant Professor at the Université de Montréal) and Dr. Véronique Bohbot (Douglas Institute researcher and associate Professor at McGill University and the Douglas Research Institute of the CIUSSS de l’Ouest-de-l’Île de Montréal) shows that while video game players (VGPs) exhibit more efficient visual attention abilities, they are also much more likely to use navigation strategies that rely on the brain’s reward system (the caudate nucleus) and not the brain’s spatial memory system (the hippocampus). Past research has shown that people who use caudate nucleus-dependent navigation strategies have decreased grey matter and lower functional brain activity in the hippocampus.
