Immunology
Immunology is a branch of biology and medicine that studies the immune system, which protects the body from infections, diseases, and foreign substances. It explores how the immune system functions, recognizes threats, and can be modified for disease treatment.
Importance of Immunology
Prevention of Diseases
Vaccines play a crucial role in preventing infections like COVID-19, polio, and measles by training the immune system to recognize and fight pathogens.
Treatment of Immune Disorders
Immunotherapy is used to treat conditions like cancer, autoimmune diseases, and allergies by boosting or regulating the immune response.
Understanding Infections
Studying the immune system helps diagnose and manage bacterial, viral, and fungal infections, leading to better treatments and disease control.
Advancing Transplant Medicine
Transplant immunology helps prevent organ rejection through HLA matching and immunosuppressive drugs, ensuring successful transplants.
