Scientific summary

Human lifestyles, life events, living environment and psychosocial factors have considerable impact on brain functioning and neuronal abilities. In parallel, these factors may also play a role in modulating both immune and neuro-immune systems. In animals, accumulating evidence indicates that environmental enrichment (EE) can mimic positive life experiences. Rodent models of EE refer to housing with increased space, physical activity, and social interactions that facilitate enhanced sensory, cognitive, motor and social stimulation. Accumulating evidence indicates that EE has powerful beneficial effects on various physio-pathological processes as it alters neurotransmitter systems, produces changes in gene expression and stimulates hippocampal neurogenesis.  Recently, EE has been shown to prevent the development of drug addiction, eliminate established addiction-related behaviors and even reduce the risks of relapse. 

A new actor has recently emerged in both alcoholism and depression fields namely the immune system. Indeed, chronic alcohol consumption augments pro-inflammatory cytokine production in the brain. Increased levels of the cytokine MCP1 (Monocyte chimoattractant protein1) were measured in post-mortem brain of alcoholics as well as in brain of alcohol-treated rodents. Interestingly, EE has also recently been shown to induce changes in the immune system. Our working hypothesis is that these changes could explain beneficial effects of EE on addiction.

Our research projet aims at (1) identifying psychosocial factors having positive impact on the success of alcohol withdrawal, (2) developing a mouse models of enriched environment having a positive impact on alcohol withdrawal (3) taking advantage of these models to investigate the role and the nature of immune cells involved in inflammation in the brain during alcohol-related addiction, withdrawal and depression.
