Recently, we demonstrated that ILC2 expand in the context of chronic liver diseases in mice and contribute to pathology in an IL-33 dependent manner. Here, we describe a protocol to isolate highly purified ILC2 from mouse livers. This procedure provides effective digestion of liver tissue and limits proteolytic degradation of cell surface receptors leading to increased yields of biologically functional cells. The number of liver resident ILC2 in the steady state is low, however their number dramatically increase upon systemic or local treatment of mice with cytokines such as IL-25 and IL-33. Using minicircle-based expression constructs for these cytokines high numbers of functional ILC2 can be isolated with the protocol provided here.
