Susan Burroughs during Photopheris treatment in
Birmingham August 2008
Photopheris is a therapeutic technique in which a patient’s lymphocytes (white blood cells) are
collected by a blood separation device. The lymphocytes are then exposed to ultraviolet light in combination with the drug 8-Methozypsorlen. This drug is a photosensitizing agent which becomes active when it is exposed to ultraviolet light. After this exposure, the lymphocytes
are returned to the patient. These treated cells stimulate the immune system to attack
the cells causing the problem. The process is similar to an auto vaccination.
