Definition


Immunology signifies the branch of medicine dedicated to studying immunity, the natural or acquired capacity of the human body to defend itself against a pathogen, here called an antigen, by implementing specifically-designed defenses. These pathogenic agents can be viruses, bacteria, autoimmune diseases, fungi, or even allergies. The body's defense system calls upon antibodies and white blood cells, specifically lymphocytes.
