RNA sequencing of lung innate lymphoid cell (ILC) populations

A transitory, interleukin-25-responsive, KLRG1high Group 2 innate lymphoid (ILC2) cell subset that migrates to mucosal tissues early during type-2 inflammation was recently identified. This study focuses on understanding the significance of this population in relation to tissue-resident ILC2 cells in the lung and intestine.  RNA-sequencing and unbiased pathway analysis revealed the AP-1 factor BATF as a potential modulator of ILC2 cell fate. For RNAseq, KLRG1-postive and KLRG1-neagive populations were sorted and compared. Examination of transcrimptome in 2 ILC cell types.
