Infection & Immunity imaging

The “Infection &Immunity imaging” core facility constitutes a unique complex combining in vivo imaging and confined facilities for studies of experimentally infected or treated animals.

The imaging suite is accessible for programs of multimodal in vivo molecular imaging using NHP models of human infectious diseases. The suite is located at the CEA Research Center of Fontenay-aux-Roses in facilities suitable for the confinement of class 2 (BSL2) and 3 (BSL3) pathogens if necessary.

 

EQUIPMENTS/TECHNOLOGIES
