Immunology

Immunology is the study of the immune system and its reaction to pathogens, as well as its malfunctions (autoimmune diseases, allergies, rejection of organ transplants, immune deficiency). The medical field that deals with these diseases is called clinical immunology, although many diseases are managed by doctors of rheumatology (auto-immune disease), nephrology (transplant rejection) and chest medicine (allergy).
