This study examines how endurance exercise with reduced muscle glycogen affects substrate utilization and signaling in human muscle fibers, finding altered fatty acid metabolism and mTORC1-autophagy dynamics.

This study characterizes the HLA-DR immunopeptidome in lung cells of early RA patients and healthy smokers, finding that HLA-DR genotype drives the immunopeptidome more than RA status or sex.

This study shows that endothelial-derived sphingolipids are essential for vascular development and systemic lipid homeostasis, with effects on retinal vascularization and liver toxicity.
