Abstract

Zipping up obesity: Chylomicrons are specialized particles that carry dietary fats from the intestine to the bloodstream for absorption into the body. Lacteals are lymphatic vessels that act as the highway for chylomicron transport, but it is unclear how passage occurs. Zhang et al. report that two endothelial cell receptors, neuropilin-1 (NRP1) and vascular endothelial growth factor receptor 1 (VEGFR1, also known as FLT1), are required to convert the entry spaces between lacteals from open junctions to closed, zipped structures (see the Perspective by McDonald). Mice that were fed a high-fat diet were subsequently rendered resistant to weight gain if NRP1 and FLT1 were inactivated. Science , this issue p. 599 ; see also p. 551

  • Button junctions can convert into zipper junctions in some disease states and revert back to buttons under appropriate experimental conditions.

    “Button junctions can convert into zipper junctions in some disease states and revert back to buttons under the appropriate experimental conditions (25).”

    From Transport and Immune Functions of the Lymphatic System. (2025) · cites this paper as [25]

    The paper reports button-to-zipper changes in mouse lacteals after genetic deletion of Nrp1 and Flt1, and fewer zipper-like junctions after dexamethasone treatment of some mutant mice (Abstract; page not provided). This supports experimentally induced, reversible junction changes, but it does not establish that the button-to-zipper conversion occurs in disease states. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
