WebHyperactivated macrophages that fail to dispose of an invader start to produce more IL-10 than IL-12, and dermal mast cells contribute large amounts of IL-4. In the continuing presence of antigen, Th2 effectors that are generated from epidermal T cells migrate to the draining lymph node and interact with antigen-stimulated B cells in this location. WebLe cellule TH2 secernono le interleuchine 4, 5, 10 e 13 (IL-4, IL-5, IL-10 e IL-13) e proteggono principalmente l'organismo contro i patogeni extracellulari.
