What is cell immunotherapy in plain words?
It is treatment in which the active agent is not a chemical drug but cells of the immune system. Blood is drawn from the patient, the cells isolated from it are worked on outside the body — activated, or given the required specificity — and returned. The aim is for the patient's own immune system to recognise its target more precisely: tumour cells in oncology, or the body's own aggressive lymphocytes in autoimmune disease.
