Th1/Th2 balance

The Th1/Th2 balance refers to two types of immune responses that help protect the body. Th1 responses mainly target viruses, bacteria, and intracellular pathogens, promoting inflammation to eliminate these threats. Th2 responses focus on fighting parasites and are involved in allergic reactions, encouraging antibody production. A proper balance between Th1 and Th2 is crucial; if Th1 is too dominant, it may cause autoimmune issues, while excess Th2 can lead to allergies. Maintaining this balance helps ensure effective immune defense without overreacting or damaging the body’s tissues.
