Single‐cell atlas of neuroglial dynamics in SNCA‐A53T Parkinson's disease mouse model

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We performed single‐cell RNA sequencing of midbrain and striatal tissues from SNCA‐A53T Parkinson's disease (PD) mice, revealing glia‐enriched PD‐risk gene signatures and disease‐specific subpopulations. Transcriptional dysregulation of key TFs (e.g., Rorb, Foxc1) and enhanced neuroinflammatory signaling (SEMA, CCL, MIF) were identified.

Semaphorin-3A as An Immune Modulator Is Suppressed by MicroRNA-145-5p

open access: yesCell Journal, 2018
Objective Semaphorin-3A (SEMA3A) and its receptors are found on some immune cells and act as suppressors of immune cells over-activation. Considering the role of SEMA3A and its down-regulation in some autoimmune diseases, as well as our bioinformatics ...

Neurovascular coupling in bone regeneration: Mechanisms, advanced biomaterials and challenges

open access: yesBMEMat, EarlyView.
This figure illustrates various material strategies for neurovascularized bone regeneration, including electroactive scaffolds, ion‐loaded materials, drug delivery systems, surface modifications, cells/cell products, growth factors, and peptides. These approaches aim to synergistically promote the regeneration of neural, vascular, and bone tissues ...

Plasma and Synovial Fluid VEGF‐A and Neuropilin‐1 in Knee Osteoarthritis: Associations With Radiographic Severity, Pain Sensitization‐Related Features, and Disease Burden

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study aimed to investigate associations of plasma and synovial fluid vascular endothelial growth factor A (VEGF‐A) and neuropilin‐1 (NRP1) levels with radiographic severity, pain sensitization‐related features, and disease burden in knee osteoarthritis (KOA). Plasma VEGF‐A and NRP1 were measured by sandwich ELISA in 120 patients with KOA (

The Relationship Between Immune Semaphorins and Myasthenia Gravis

open access: yesBrain and Behavior
Objective Myasthenia gravis (MG) is an autoimmune disease involving several immune mechanisms. Recently, semaphorins have emerged as potential diagnostic and prognostic biomarkers in autoimmune neurological and non‐neurological diseases.

Palmitoylation regulates neuropilin-2 localization and function in cortical neurons and conveys specificity to semaphorin signaling via palmitoyl acyltransferases

open access: yeseLife, 2023
Secreted semaphorin 3F (Sema3F) and semaphorin 3A (Sema3A) exhibit remarkably distinct effects on deep layer excitatory cortical pyramidal neurons; Sema3F mediates dendritic spine pruning, whereas Sema3A promotes the elaboration of basal dendrites ...

From patient to tumor organoid: Culture protocol choice controls glioblastoma tumor architecture and identity

open access: yesBrain Pathology, EarlyView.
How glioblastoma organoids are made shapes what they become. Fragment‐based cultures preserve extracellular matrix networks, cellular diversity, and primary tumor identity, whereas dissociation‐based cultures shift toward growth‐adapted states and simplified microenvironments. Abstract Patient‐derived tumor organoids are widely used in cancer research,

Predicting Relevant Microglia‐Associated Cell–Cell Communication Pathways in Alzheimer's Disease: A Role for SPP1

open access: yesGlia, Volume 74, Issue 10, October 2026.
We used CellChat to infer altered cell–cell communication in Alzheimer's disease Microglia signal to each other via SPP1 in Alzheimer's disease. SPP1‐expressing microglia are present around amyloid‐β plaques. ABSTRACT Microglia play a key role in the pathophysiology of Alzheimer's Disease (AD) and their increased heterogeneity likely affects disease ...

Exercise‐specific plasma proteomic signatures in racehorses: Candidates for training adaptation and peak load monitoring

open access: yesEquine Veterinary Journal, Volume 58, Issue 5, Page 1396-1412, September 2026.
Abstract Background Racehorses undergo profound physiological changes with training and competition, but current biomarkers inadequately capture the complex molecular dynamics of exercise. This study aimed to identify novel plasma biomarkers of training adaptation and peak load using high‐throughput proteomics.

Autocrine semaphorin 3A signaling promotes glioblastoma dispersal [PDF]

open access: yesOncogene, 2009
Glioblastoma multiforme (GBM) is the most malignant glioma type with diffuse borders due to extensive tumor cell infiltration. Therefore, understanding the mechanism of GBM cell dispersal is critical for developing effective therapies to limit infiltration.
