The July issue of Mucosal Immunology is online now.

This cover image shows a histologic section of the urinary bladder that was stained with DAPI (blue), Epcam-1 (white) and F4/80 (red). The image indicates the dense network of macrophages in the lamina propria. Upon infections with uropathogenic E.coli, these macrophages migrate towards the infection to fight off the infection.
