The discipline concerned with the immune system. Immunologists study the immune system’s functioning and investigate and treat immune system disorders, including allergies, autoimmune disorders, and immunodeficiency disorders such as AIDS. Immunologists are also concerned with finding ways in which the immune system can be stimulated to provide immunity. In addition, they play a role in transplant surgery, looking preoperatively for a good match between recipient and donor organ, and suppressing the recipient’s immune system after transplantation to minimize the chances of organ rejection.
