Among them, ILC2s (group 2 ILC) can produce type 2 cytokines in response to alarmin cytokines such as IL-33, IL-25, and TSLP (Thymic Stromal Lymphopoietin), and so play an important role in allergic illnesses, anti-helminth infection, and metabolic balance [50]. Here, TSLP is linked to helminthiasis.
