Dysregulation of Caveolin-1 (CAV1), a key component of caveolae, leads to pleiotropic disorders; yet, the mechanisms controlling its trafficking remain unclear. Here, we show that the lipid droplet (LD) biogenesis factor seipin controls CAV1 localization. Seipin deficiency in mice and HeLa cells ...
Mammalian organs continuously exchange circulating metabolites for organismal health and survival. However, the landscape of this fundamental process and its perturbation by diet and disease is unknown. Using arteriovenous metabolomics, tissue transcriptomics, hormone arrays and multiple metaboli...
The PD-1/PD-L1 axis represents a cornerstone of cancer immunotherapy, yet the dynamic shuttling of PD-L1 between endosomal recycling and lysosomal degradation routes limits durable responses. Using a CRISPR screen targeting glycosphingolipid metabolism, we identify TM9SF2 as a key regulator of PD...
