Chemokines in pathologies and Inflammation - Christophe COMBADIERE

Team members

Team Research program

Inflammation is a hallmark of numerous human diseases and a key aspect of it is trafficking of immune cells into and out of the specific injured tissues. Thus, the challenge for the future will be to identify the trafficking molecules that will most specifically inhibit the key subsets of cells that drive disease processes without affecting the migration and function of leukocytes required for protective immunity.
Chemokines (CK) are typical immune and inflammatory mediators that not only allow a rapid and appropriate leukocyte migration to emergency signals but also control cellular responses. CK and their receptors (CKR) are central to the inflammatory process and are thus attractive targets for the pharmaceutical industry.
Our research program aims to establish the evidence that the CK-based therapy could become a new way of treatment of inflammatory diseases. It includes four approaches:

  1. structural and functional analysis of inflammatory CK and CKR,
  2. ex vivo studies that analyze the role of CK/CKR on subsets of leukocytes in human diseases,
  3. in vivo studies that characterize the role of CK/CKR in inflammatory mouse models,
  4. the development of CK/CKR-based therapeutic tools.

The project pipeline, from molecular analysis, proof-of-principle evaluation in murine models to valorization, is taking advantage of new short peptide-based antagonist candidates that have already shown strong efficacy in limiting monocyte infiltration in organs.
