Single-cell RNA-seq identifies a PD-1 hi ILC progenitor and defines its development pathway

Single-cell RNA sequencing of bone marrow innate lymphoid cell (ILC) precursors reveals that PD-1 marks a committed ILC progenitor and that ILC2 development requires Bcl11b and IL-25R expression; activated ILCs can also be depleted by a PD-1 antibody.
