Damage control: Rorγt+ innate lymphoid cells in tissue regeneration

► Rorγt+ ILC are essential for lymphoid organogenesis. ► Rorγt+ ILC in adults function in mucosal homeostasis and immunity. ► Rorγt+ ILC are involved in protecting intestinal progenitor cells after damage. ► Rorγt+ ILC enhance thymic epithelial recovery after radiation insult. ► Rorγt+ ILC are important players in epithelial tissue regeneration.
