Abstract Innate lymphoid cells (ILC) are increasingly acknowledged as important mediators of immune homeostasis and pathology. ILC act as early orchestrators on immunity, responding to epithelial-derived signals by expressing an array of cytokines and cell surface receptors, which shape subsequent immune responses. As such, ILC make up interesting therapeutic targets for several diseases. In allergy and asthma, group 2 ILC (ILC2) produce high amounts of IL-5 and IL-13, thereby contributing to type 2 mediated inflammation. ILC3 are implicated in intestinal homeostasis and psoriasis pathology through abundant IL-22 production, whereas ILC1 are accumulated in chronic inflammation of the gut (IBD) and lung (COPD) where they contribute to IFN-γ-mediated inflammation. Although the ontogeny of mouse ILC is slowly unraveling, the development of human ILC is far from understood. In addition, the growing complexity of the human ILC family in terms of previously unrecognized functional heterogeneity and plasticity has generated confusion within the field. Here we provide an updated view on the function and plasticity of human ILC in tissue homeostasis and disease.
