1 CerS6-Derived Sphingolipids Interact with Mff and Promote Mitochondrial Fragmentation in Obesity. Sphingolipids ceramide synthase 6 Homo sapiens
2 Here we demonstrate that the C16:0 sphingolipid synthesizing ceramide synthases, CerS5 and CerS6, affect distinct sphingolipid pools and that abrogation of CerS6 but not of CerS5 protects from obesity and insulin resistance. Sphingolipids ceramide synthase 6 Homo sapiens
3 Here we demonstrate that the C16:0 sphingolipid synthesizing ceramide synthases, CerS5 and CerS6, affect distinct sphingolipid pools and that abrogation of CerS6 but not of CerS5 protects from obesity and insulin resistance. Sphingolipids ceramide synthase 6 Homo sapiens
4 Here we demonstrate that the C16:0 sphingolipid synthesizing ceramide synthases, CerS5 and CerS6, affect distinct sphingolipid pools and that abrogation of CerS6 but not of CerS5 protects from obesity and insulin resistance. Sphingolipids ceramide synthase 6 Homo sapiens
5 We identify proteins that specifically interact with C16:0 sphingolipids derived from CerS5 or CerS6. Sphingolipids ceramide synthase 6 Homo sapiens
6 Here, only CerS6-derived C16:0 sphingolipids bind the mitochondrial fission factor (Mff). Sphingolipids ceramide synthase 6 Homo sapiens
7 Our experiments reveal an unprecedented specificity of sphingolipid signaling depending on specific synthesizing enzymes, provide a mechanistic link between hepatic lipid deposition and mitochondrial fragmentation in obesity, and define the CerS6-derived sphingolipid/Mff interaction as a therapeutic target for metabolic diseases.
