Main interests

????????????????????

Immune cells must exchange and store information in the course of searching for and responding to disease. This information exchange is relayed through specialized membrane receptors that initialize signaling cascades, which culminate in the production of immune mediators responsible for disease resolution.

Figure 2

On the T cell this information is received through a specific membrane receptor - the T cell receptor- that is responsible for integrating the information relayed through a signaling cascade that culminates in the production of immune mediators that will clear the infection.

 
 
 

Overall, our lab is interested in determining how immune receptor signaling is able to convey distinct immune responses that protect us against disparate aggressions (fungus, virus, bacteria, cancer, etc.).
Our current research is comprised of three interconnected axis:
1- To establish how signaling architecture regulates immune responses;
2- To determine how alterations in signaling lead to auto-immunity;
3- To decipher how pathogens (HIV-1) exploit the immune signaling to their own advantage.

 
 
Figure 3 We use tissue samples from patients, as a privileged disease model, to investigate the role of anomalous T signaling in the chronic immune activation underpinning immunodeficiency and auto-immune diseases. We combine immune physiology, cell biology and signaling with super-resolution microscopy approaches to determine the molecular and cellular mechanisms involved and to identify genes and signaling pathways implicated.
Our final goal is to identify biomarkers and molecular targets that will enable for the development of novel therapies.
