Impact of ExtraCorporeal Phototherapy (ECP) on Auxiliary Follicular T-lymphocytes and Circulating B-lymphocytes During Chronic AntiBody-Mediated Rejection in Kidney Transplantation.

The principle of ECP is to collect mononucleated cells from the blood by centrifugation. After purification, the mononucleated cells are incubated ex-vivo with a photo-activatable DNA intercalating agent (8-methoxypsoralen, UVADEX®), then re-injected to the patient.
