Scientific summary

For the last 15 years, I have studied the functions of the leukocyte Ca2+ channels. These channels open after the emptying of the Ca2+ ions of the endoplasmic reticulum, and are known as "store-operated Ca2+ channels". The absence of the store-operated Ca2+ entry ("SOCE") leads to severe combined immunodeficiencies. Recently, the two main proteins responsible for the SOCE were characterized: STIM1 and Orai1.

My main project is to develop new effectors of the SOCE to control the activity of the leukocytes, and thereafter the immun system. This kind of effectors could also be interesting to control the proliferation of some cancerous cells where the Orai1 channel is the main Ca²⁺ entry (lymphomas, leukemias, breast cancers...).

I am also interested in pathologies associated with a disturbance of the Ca²⁺ signalling in liver pathologies
