ONLINE COVER Clock-Watching Intestinal ILC3s. On this month's cover is a sundial, one of the earliest methods to keep track of time. Teng et al. and Wang et al. found that expression of several key genes in murine intestinal group 3 innate lymphoid cells (ILC3s) exhibited circadian oscillation. Deletion of key circadian clock genes in mice compromised intestinal ILC3 development and function. The roles that clock genes play in ILC3 biology are discussed by Burrows and Mortha in a related Focus. [CREDIT: ISTOCK.COM/DBENCEK]
