Created in 2012, the research axes of the team focus on the regulation of cytokine production during viral infection and inflammation in autoimmune diseases.

Scientific projects and goals:

  • Drug discovery:

The laboratory generates and optimizes original screening assays dedicated to the identification of immune modulatory molecules. These assays are used to screen in house or external libraries.

Once identify, the lab have an establish work flow to validate lead compounds, going from in house chemical optimization, evaluation on in vitro and vivo model of inflammation and infection, to evaluation on material from patients with autoimmune disease such as lupus.

CXCR4 dependent immune regulation in inflammatory and infectious models.

We have recently shown that some small endogenous amines regulate interferon and cytokine production in innate immune cells by engaging the chemokine receptor CXCR4. Our future projects aim to design, synthetize and characterize small compounds able to modulate inflammation through CXCR4. Furthermore, it is essential to understand the molecular mechanism by which natural amines regulate innate immunity. Our discoveries have a great potential in clinics for treating auto-immune diseases like lupus or chronic infectious diseases as HIV.

  • Pathophysiology of pediatric rheumatoid diseases.

Our recent work highlight the association between circulating interferon levels and diseases activity in patients suffering of juvenile dermatomyositis (JDM). Interferon levels could also be used to stratified patients with distinct clinical pictures, suggesting a different roles depending on JDM subtypes. We now aim to better characterize the overall inflammatory profiles of JDM patients in order to stratify patients early on during the diseases history in order to adapt treatment regimen.
