Thymosin Alpha‐1 Provides Direct Neuroprotection by Engaging the Orexin Receptor HCRTR1 to Suppress Neuronal Necroptosis

Advanced Science, EarlyView.
In this study, we unveil a thymus‐brain endocrine axis wherein Tα1 engages HCRTR1 to inhibit RIPK3‐mediated necroptosis. This study nominates the Tal‐HCRTR1‐RIPK3 axis as a potent and clinically translatable therapeutic target for stroke and neurodegeneration.

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Nano Proton Scavengers Modulate Endosomal pH to Inhibit Microglial Activation and Enhance Stroke Recovery

Advanced Science, EarlyView.
Amphiphilic sulfonated chitosan nanoparticles buffer endo/lysosomal acidity in microglia by limiting V‐ATPase membrane recruitment and restoring endosomal homeostasis. Following systemic administration, they accumulate in the ischemic hemisphere partly through association with infiltrating immune cells, suppress TLR3/IRF3 and TLR4/NF‐κB signaling ...

Effect of Phenylephrine on Cerebrovascular Regulation: A Translational Perspective

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Phenylephrine is an alpha 1‐adrenergic receptor (α1R) agonist. Evidence indicates activation of α1Rs can initiate both vasoconstrictor and dilator signaling. How phenylephrine affects cerebrovascular regulation remains unclear.

14‐3‐3γ Protects Against Postoperative Cognitive Dysfunction by Regulating Tau Thr205 Phosphorylation and Synaptic Integrity

Advanced Science, EarlyView.
Integrative multi‐cohort analyses identify 14‐3‐3γ as a biomarker and regulator of cognitive vulnerability. Experimental studies show that 14‐3‐3γ loss is associated with Tau Thr205 phosphorylation, synaptic dysfunction, and cognitive impairment, while genetic overexpression or pharmacological stabilization of 14‐3‐3γ confers protective effects in ...

Actions of platelet-activating factor on isolated feline and human cerebral arteries

, 1990
The effects of platelet-activating factor (PAF) were studied on isolated feline basilar arteries (BAs) and human pial arteries (PAs). PAF contracted the BAs by 67% of the contraction induced by 124 mM K+ and the PAs by 80%.

Nrsn1–Smarcc1 Coupling Regulates Neural Stem Cell Differentiation and Chronic‐phase Recovery After Ischemic Stroke

Advanced Science, EarlyView.
In the post‐stroke brain, Foxa2 induces the transcriptional upregulation of Nrsn1 in NSCs. Nrsn1 functionally couples with Smarcc1, modulating its nuclear availability and protein abundance, thereby influencing Smarcc1‐associated regulatory programs linked to neuronal lineage commitment. Through this coupling, Nrsn1 promotes the differentiation of NSCs
