Dennd5b-deficient mice show a near-complete blunting of the postprandial mesenteric lymph lipidomic response after duodenal lipid dosing, with markedly attenuated export across lipid classes.
- Why it matters: Chylomicron composition may shape peripheral lipid metabolism, but newly secreted chylomicrons’ lipid makeup after feeding is not fully defined, especially under impaired secretion.
- What they did: Using a conscious mesenteric lymph fistula model, the study performed mass spectrometry-based lipidomics on lymph from wild type and Dennd5b knockout mice after duodenal lipid administration.
- The result: Wild type mice had increased lymphatic triglyceride output and shifts across glycerolipids, glycerophospholipids, and sphingolipids, with disproportionate rises in ceramides and hexosylceramides; Dennd5b deficiency blunted these changes and altered baseline lipid composition.
