What is Immunology?
Immunology is the branch of biomedical science that deals with the study of the immune system, its structure, function, disorders, and how it defends the body against disease.
Meaning of Immunology
The word Immunology comes from:
-
“Immunis” (Latin) meaning exempt or free from burden.
-
“Logy” meaning the study of.
So, Immunology literally means the study of immunity.
Definition of Immunology
Immunology is the scientific study of the immune system — the body’s defense mechanism against infections, diseases, and foreign substances.
It involves understanding:
-
How the immune system protects the body from pathogens.
-
How it can malfunction (as in autoimmune diseases, allergies, or immunodeficiencies).
-
How it can be harnessed for vaccines, treatments, and therapies (e.g., cancer immunotherapy).
Key Areas in Immunology
-
Innate Immunity – The body’s first line of defense (e.g., skin, inflammation).
-
Adaptive Immunity – Specific, learned responses involving lymphocytes (e.g., B cells and T cells).
-
Immunopathology – Study of diseases caused by immune system dysfunction.
-
Clinical Immunology – Application of immunology in diagnosing and treating diseases.
-
Immunotherapy – Using immune-based approaches to treat diseases like cancer or autoimmune conditions.
