Targeting a Myeloid–Regulatory B Cell Network Reverses Immune Paralysis in Periprosthetic Joint Infections

Advanced Science, EarlyView.
Periprosthetic joint infection establishes a sophisticated immunosuppressive network between CXCR4+ PMN‐MDSCs and Bregs, inducing profound CD8+ T cell paralysis. Alendronate effectively disrupts this CXCR4+ PMN‐MDSC–Breg axis by targeting STAT3, thereby restoring local immune surveillance.

Image_2_Mediating immunosuppressive functions: a new perspective on the complex immunological properties of SEMA4D in the tumor microenvironment.tif

, 2023
Semaphorin 4D (SEMA4D) is considered a new antitumor target closely related to immune cells. However, understanding the role of SEMA4D in the tumor microenvironment (TME) is limited.

Targeting neutrophil extracellular traps in metabolic and immune niche: Nanomaterials for diabetes tissue regeneration

BMEMat, EarlyView.
The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.

Sema4D induces angiogenesis through Met recruitment by Plexin B1

Blood, 2005
AbstractSemaphorins, a large family of membrane-bound and secreted proteins, signal through their transmembrane receptors, the plexins. Semaphorins and plexins share structural homologies with scatter factor receptors, a family of tyrosine kinase receptors for which Met is the prototype. Semaphorins have been studied primarily in the developing nervous

Optimization of photobiomodulation therapy for spinal cord injury: A review

Photochemistry and Photobiology, EarlyView.
Photobiomodulation (PBM) therapy in the red and near‐infrared range can significantly modulate the secondary injury response and promote the reparative and regenerative potential of neural tissue after spinal cord injury (SCI). At present, due to the nature of delivery methods, the most effective dose and irradiance at the injury site to optimize ...

Sema4D/CD100 Deficiency Leads to Superior Performance in Mouse Motor Behavior [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 2009
Background: Sema4D/CD100 is a type of class 4 semaphorin, exhibiting crucial rôles in growth cone guidance in developing neurons. Sema4D is widely expressed throughout the central nervous system in embryonic mouse brain, and is selectively localized to oligodendrocytes and myelin in the postnatal brain. However, direct evidence of the actual

RXR Gamma Enables Oligodendrocyte Differentiation by Suppressing Sonic Hedgehog Signaling

Glia, Volume 74, Issue 6, June 2026.
Using pharmacogenetic approaches, Baldassarro et al. demonstrate that RXRγ suppresses the SHH signaling pathway in OPCs to ensure their efficient differentiation following T3 stimulation. Accordingly, Rxrg−/− OPCs displayed compromised differentiation which was normalized by the pharmacological inhibition of the hyperactive SHH pathway.

Anti-semaphorin 4D immunotherapy ameliorates neuropathology and some cognitive impairment in the YAC128 mouse model of Huntington disease

Neurobiology of Disease, 2015
Huntington disease (HD) is an inherited, fatal neurodegenerative disease with no disease-modifying therapy currently available. In addition to characteristic motor deficits and atrophy of the caudate nucleus, signature hallmarks of HD include behavioral ...
