The Th2 response is a type of immune reaction primarily driven by T-helper 2 (Th2) cells, which play a crucial role in orchestrating the body’s defense against extracellular pathogens like helminths and allergens. This response is characterized by the production of specific cytokines that promote B-cell activation, class switching to IgE, and the recruitment of eosinophils and mast cells, ultimately leading to an effective immune response against parasites and mediating allergic reactions.
