J Immunology

Immunology is the study of the immune system, which is the body's defense network against harmful substances like bacteria, viruses, fungi, and parasites. It involves a complex system of cells, tissues, and molecules that work together to identify and eliminate threats, while distinguishing them from the body’s own cells. Immunology helps us understand how our immune system protects us, how it sometimes malfunctions, leading to allergies or autoimmune diseases, and how we can harness its power through vaccines and treatments to prevent or fight illnesses effectively.
