Immunology

Immunology is the branch of biology focused on the study of the immune system, which is the complex network of cells, tissues, and organs that defends the body against pathogens such as bacteria, viruses, and parasites. It encompasses the mechanisms of immune response, the interactions between various immune cells, and the body's ability to distinguish between self and non-self. Immunology also examines the principles behind vaccinations, allergies, autoimmune diseases, and immunodeficiencies, seeking to understand how to harness the immune system for therapeutic purposes and improve human health.
