摘要： Group 2 innate lymphoid cells (ILCs), or ILC2s, are a subset of recently identified ILCs, which play important roles in innate immunity by producing type 2 effector cytokines. Several transcription factors have been found to have critical functions in the development of both ILC2s and T cells. We report here that Bcl11b, a transcription factor essential in T cell lineage commitment and maintenance, is specifically expressed in progenitors committed to the ILC2 lineage and is required for ILC2 development. The Bcl11b gene is expressed in similar to 28% of ILC progenitors (ILCPs; common helper innate lymphoid progenitors or ILCPs expressing either ID2 or promyelocytic leukemia zinc finger, respectively). Both in vitro and in vivo, these Bcl11b-expressing early ILCPs generate only ILC2s. Inactivation of Bcl11b causes a complete loss of ILC2 development from hematopoietic progenitors, which is confirmed upon immune challenge with either papain administration or influenza virus infection.
