Tumor‐Derived Exosomal TAGLN2 Promotes Metastasis by Inducing Vascular Permeability and Angiogenesis via the NRP1/SEMA4D/YAP Axis

open access: yesAdvanced Science, Volume 13, Issue 29, 22 May 2026.
Gastric cancer‐derived exosomal TAGLN2 is identified as a key mediator of vascular reprogramming, with significantly elevated levels detected in patient serum. Independent of canonical SEMA4D signaling, it nucleates a cytoplasmic TAGLN2/NRP1/SEMA4D ternary complex that dually activates YAP, promoting angiogenesis, vascular dysfunction, and metastasis ...

Identification and characterization of critical determinants in plexin signaling

open access: yes, 2022
Semaphorins, a class of soluble and membrane-bound ligands, and their corresponding receptors, plexins, play a pivotal role in organogenesis, physiology of different tissues and organ systems, as well as in the development of diseases.

Rap2 and TNIK control Plexin-dependent tiled synaptic innervation in C. elegans

open access: yeseLife, 2018
During development, neurons form synapses with their fate-determined targets. While we begin to elucidate the mechanisms by which extracellular ligand-receptor interactions enhance synapse specificity by inhibiting synaptogenesis, our knowledge about ...

How does type 2 diabetes modify the risk of Alzheimer's disease?

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract Type 2 diabetes (T2D) and Alzheimer's disease (AD) are both increasing exponentially worldwide. T2D has also been identified as one of 14 modifiable risk factors for dementia, but the mechanism is unknown. T2D could promote dementia via vascular or AD neuropathological changes, and mechanistic hypotheses include central insulin resistance and ...

Sema4C-Plexin B2 signalling modulates ureteric branching in developing kidney

open access: yes, 2011
Semaphorins, originally identified as axon guidance molecules, have also been implicated in angiogenesis, function of the immune system and cancerous growth.

Diversity of oligomerization in Drosophila semaphorins suggests a mechanism of functional fine-tuning

open access: yesNature Communications, 2019
Semaphorin-plexin interactions regulate various developmental processes in Drosophila but the structural basis of these signaling events is unclear. Here, the authors present crystal structures of all Drosophila class 1 and 2 semaphorins, and elucidate ...

Evaluating Protein Enrichment Methods to Improve Biomarker Discovery in Equine Cerebrospinal Fluid

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Here, we compared two protein enrichment methods—ProteoMiner Small‐Capacity and PreOmics Enrich‐iST—for proteomic analysis of equine cerebrospinal fluid (CSF). PreOmics Enrich‐iST achieved superior depletion of high‐abundance proteins and identified a greater number of low‐abundance, neuropathology‐relevant proteins than ProteoMiner or native digestion.

The Activity of the Plexin-A1 Receptor Is Regulated by Rac [PDF]

open access: yesJournal of Biological Chemistry, 2004
Plexins constitute a large family of transmembrane proteins that act as receptors for the semaphorin family of ligands. They are best known for their role in growth cone guidance, although they also are widely expressed outside the nervous system. Plexins are thought to control axon guidance by modifying the growth cone cytoskeleton, and Rho GTPases ...

Plexin Signaling via Off-Track and Rho Family GTPases

open access: yes, 2001
Two papers in this issue of Neuron examine new aspects of Semaphorin signaling via Plexin receptors. Winberg et al. present evidence that the transmembrane protein Off-track (OTK) interacts biochemically and genetically with Plexin A and is important for

Semaphorin signaling in vertebrate neural circuit assembly

open access: yesFrontiers in Molecular Neuroscience, 2012
Neural circuit formation requires the coordination of many complex developmental processes. First, neurons project axons over long distances to find their final targets and then establish appropriate connectivity essential for the formation of neuronal ...
