Abstract

Shear stress on arteries produced by blood flow is important for vascular development and homeostasis but can also initiate atherosclerosis 1. Endothelial cells that line the vasculature use molecular mechanosensors to directly detect shear stress profiles that will ultimately lead to atheroprotective or atherogenic responses 2. Plexins are key cell-surface receptors of the semaphorin family of cell-guidance signalling proteins and can regulate cellular patterning by modulating the cytoskeleton and focal adhesion structures 3-5. However, a role for plexin proteins in mechanotransduction has not been examined. Here we show that plexin D1 (PLXND1) has a role in mechanosensation and mechanically induced disease pathogenesis. PLXND1 is required for the response of endothelial cells to shear stress in vitro and in vivo and regulates the site-specific distribution of atherosclerotic lesions. In endothelial cells, PLXND1 is a direct force sensor and forms a mechanocomplex with neuropilin-1 and VEGFR2 that is necessary and sufficient for conferring mechanosensitivity upstream of the junctional complex and integrins. PLXND1 achieves its binary functions as either a ligand or a force receptor by adopting two distinct molecular conformations. Our results establish a previously undescribed mechanosensor in endothelial cells that regulates cardiovascular pathophysiology, and provide a mechanism by which a single receptor can exhibit a binary biochemical nature.

  • A recent study reported a semaphorin-independent mechanosensitive function for Plexin-D1, a paralog of Plexin-B1, to detect blood flow shear stress in endothelial cells.

    “Interestingly, a recent study also reported a semaphorin-independent mechanosensitive function for Plexin-D1, a paralog of Plexin-B1, to detect blood flow shear stress in endothelial cells62.”

    From Regulation of cell distancing in peri-plaque glial nets by Plexin-B1 affects glial activation and amyloid compaction in Alzheimer’s disease (2024) · cites this paper as [62]

    The main text (page unavailable) reports that PlxnD1 is a direct force sensor in endothelial cells and is required for their response to blood-flow shear stress. It also states that this mechanotransduction is independent of the semaphorin ligand Sema3E. Our copy does not identify PlxnD1 as a paralog of Plexin-B1, so that parenthetical part is not supported by this source. (LLM, conf=0.87)

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.
