The main interest of our laboratory is to elucidate the peripheral immune response after cerebral ischemia and to identify deleterious and protective pathways that are associated with this response.

Cerebral immune cell infiltration after stroke
Inflammation is a central aspect in the pathophysiology of stroke, a leading-cause of death and serious disability worldwide. Although numerous experimental studies based on immune modulatory therapies have shown promise, attempts to use such strategies in the clinic have not been successful. One of the main reasons is our poor understanding of the post-ischemic inflammation process. While the inflammatory response originates in the ischemic territory, immune cells of primary and secondary lymphoid organs are activated by inflammatory mediators released from the ischemic territory and by neurohumoral signals generated by the ischemic brain. This immune response – a hallmark of experimental and clinical stroke – has deleterious and beneficial components. My laboratory aims to identify molecular and cellular circuits that govern the peripheral immune response to stroke. Specifically, we are interested in:
