Cover: The image is an immunofluorescent micrograph of murine skeletal muscle lacking adipose triglyceride lipase (ATGL), the rate-limiting enzyme in triacylglycerol hydrolysis, demonstrating massive fiber type–specific intramyocellular lipid accumulation. Skeletal muscle derived from skeletal muscle–specific ATGL knockout (SMAKO) mice were stained with LipidTOX Red for neutral lipids (red), Tom20 for mitochondria (green), and phalloidin for F-actin (blue).

Authors are invited to submit images for use on the cover of Diabetes. Black and white or color photographic or photomicrographic images are acceptable. Cover image submission and selection is completely independent of article submission and the peer-review process. Click here for more information.
