Innate lymphoid cells (ILCs) are a family of immune effector cells that have important roles in host defense, metabolic homeostasis and tissue repair but can also contribute to inflammatory diseases such as asthma and colitis. These cells can be categorized into three groups on the basis of the transcription factors that direct their function and the cytokines they produce, which parallel the effector functions of T lymphocytes. The hierarchy of cell-fate-restriction events that occur as common lymphoid progenitors become committed to each of the ILC lineages further underscores the relationship between these innate immune cells and T lymphocytes. In this Review we discuss the developmental program of ILCs and transcription factors that guide ILC lineage specification and commitment.

Daussy, C. et al. T-bet and Eomes instruct the development of two distinct natural killer cell lineages in the liver and in the bone marrow. J. Exp. Med. 211, 563–577 (2014).In this paper, an EomesGFP reporter mouse is used to distinguish two subsets of NK cells that are Eomes+ or Eomes− in the liver and bone marrow. These subsets have different functional properties and gene-expression profiles that are now known to distinguish conventional NK cells (Eomes+) from ILC1s and some tissue-resident NK cells (Eomes−T-bet+). This paper builds on observations made in reference 39, which identifies these two subsets on the basis of their differential dependence on Eomes and T-bet. This paper also shows that T-bet can repress Eomes when expressed in bone-marrow NK cells.

Lee, M.W. et al. Activated type 2 innate lymphoid cells regulate beige fat biogenesis. Cell 160, 74–87 (2015).This paper demonstrates that IL-33-elicited ILC2s, in collaboration with eosinophil-derived cytokines, promote a subset of adipocyte progenitors to proliferate and commit to differentiation to the beige-fat lineage under the influence of the cytokine receptor IL-4Rα. Therefore, ILC2s might contribute to thermal homeostasis by regulating the production of beige or brown fat.

PLZF marks a portion of all cells of the ILC1, ILC2 and ILC3 subsets and is required for the development of ILC2s and a subset of ILC1s.

Chea, S. et al. Single-cell gene expression analyses reveal heterogeneous responsiveness of fetal innate lymphoid progenitors to notch signaling. Cell Rep. 14, 1500–1516 (2016).In this study, single-cell gene expression analysis is used to classify fetal multipotent innate lymphoid cell progenitors into two subsets that correlated with the retention (αLP1) or loss (αLP2) of T lymphocyte potential. The authors then assess the requirements for Notch signaling in the αLP2 subset and find that Notch signaling is required in only a subset of ILC2 progenitors and that the main effect of Notch signaling is on proliferation. This study demonstrates the strength of single-cell gene-expression analysis for classification of progenitor cells and provides insights into the controversial requirements for Notch signaling in ILCs.

Yang, Q. et al. T cell factor 1 is required for group 2 innate lymphoid cell generation. Immunity 38, 694–704 (2013).In this paper, a Tcf7GFP reporter is used to identify a multipotent progenitor of all ILCs in the lineage-marker-negative population of bone marrow. This progenitor, called the 'early innate lymphoid progenitor', has a gene-expression program similar to that of CLPs but differs from CLPs in its expression of Id2 and the absence of Flt3 and CD127.
Califano, D. et al. Transcription factor Bcl11b controls identity and function of mature type 2 innate lymphoid cells. Immunity 43, 354–368 (2015).This paper, along with refs. 74 and 75 , demonstrates a specific requirement for Bcl-11b in the ILC2 lineage. This paper shows that Bcl-11b directly regulates Gfi1 to control the ILC2-associated genes Gata3 and Il1rl1 and represses the ILC3-associated cytokine-encoding gene Il17a . These Bcl-11b-deficient ILC2s make IL-17 rather than IL-13 when activated and recruit neutrophils rather than eosinophils to the lungs.

In contrast, conventional NK cells are rapidly equilibrated in these mice. This paper raises the question of the origins of these tissue-resident ILCs.
