LRRK2 and Nod2 promote lysozyme sorting in Paneth cells

Paneth cell dysfunction has been linked to Crohn's disease. Nod2 and LRRK2, two genetic susceptibility factors for this disease, are now shown to have a role in regulating the sorting of lysozyme in Paneth cells and its secretion into the crypt space and, ultimately, in maintenance of the intestinal barrier.
