Type 2 innate lymphoid cells (ILC2s) arise, under the control of the transcription factors retinoic acid receptor related orphan receptor α (RORα) and GATA-binding factor 3 (GATA3), from lymphoid progenitors in the bone marrow, to secrete Th2 cytokines including IL-5 and IL-13. ILC2s contribute to the initiation as well as to the maintenance of the adaptive type 2 immune response. Recent researches demonstrate that ILC2s play a key role in allergic asthma. The study of ILC2s has great significance to understand the pathogenesis of allergic asthma. This review will describe the recent progress on identification, d
