The CRCI2NA is a multi-team research structure led by a director and an assistant director. In January 2022, it will consist of twelve research teams under the responsibility of one or two researchers or teacher-researchers. The objectives of the CRCI2NA are to better see, understand and treat human cancer pathologies. To this end, each team studies one or more components of tumors, which they understand as a cellular ecosystem whose establishment and evolution are governed, in particular, by the communications that are exchanged. They do this by deploying a wide range of scientific, technical and technological skills that define the CRCI2NA as a multidisciplinary site, mainly under the responsibility of the ITMO Cancer but also of the ITMO I3M and Technologies for Health.
