title: Innate immune cells to the help.
abstract: A study by Halim and Steer (2014) in this issue of Immunity shows that innate lymphoid cells type 2 (ILC2s) are crucial for inducing adaptive T helper 2 immunity by providing interleukin-13. Another study by van Dyken et al. (2014) shows that ILC2s control eosinophilia and alternative activation of macrophages.
