The role of ILC2 in pathology of type 2 inflammatory diseases

Curr Opin Immunol. 2014 Dec:31:115-20. doi: 10.1016/j.coi.2014.10.007. Epub 2014 Oct 30.

Abstract

Group 2 innate lymphoid cells (ILC2) which are strategically interspersed throughout barrier surfaces are important regulators of type 2 immune reactions, particularly against helminthic parasites. ILC2 are also involved in tissue homeostasis and repair. Studies in a variety of animal models have demonstrated that when dysregulated or chronically activated, ILC2 can contribute to the pathology of allergic inflammatory diseases such as allergic asthma and atopic dermatitis. Here we discuss new findings of the cross talk of ILC2 with other hematopoietic cells, in particular T cells, and review recent information on the role of ILC2 in type 2 inflammatory diseases.
