Summary
This summary is machine-generated.Vitamin C reduces neurological damage from ischemic stroke by modulating regulatory T cells and activating the FOXP3-STAT3 pathway. This antioxidant enhances recovery and protects brain cells from injury.
Area Of Science
- Neuroscience
- Immunology
- Biochemistry
Background
- Ischemic stroke is a leading cause of disability, necessitating novel therapeutic strategies.
- Vitamin C, a potent antioxidant, shows promise in neuroprotection.
- Regulatory T cells (Tregs) and the JAK/STAT3 pathway are implicated in stroke pathology.
Purpose Of The Study
- To investigate the therapeutic effects of Vitamin C on the JAK/STAT3 signaling pathway in ischemic stroke.
- To elucidate the molecular interaction between FOXP3 and STAT3 in the context of Vitamin C treatment.
- To evaluate Vitamin C's impact on neurological impairment and cellular mechanisms post-ischemic stroke.
Main Methods
- Transient middle cerebral artery obstruction (MCAO) model in vivo.
- Assessment of neurological function using Garcia JH score.
- Analysis of protein expression, cell infiltration, and Treg proportions via Western blotting, flow cytometry, and immunofluorescence staining.
Main Results
- Vitamin C significantly ameliorated neurological dysfunction and neuronal injury following ischemic stroke.
- Reduced glial cell infiltration was observed in the stroke-affected brain area.
- Vitamin C modulated Treg cell populations and activated the Treg-STAT signaling pathway, linked to FOXP3 and STAT3 interactions.
Conclusions
- Vitamin C demonstrates significant neuroprotective effects in ischemic stroke models.
- The therapeutic mechanism involves the activation of the Treg-STAT pathway, specifically through FOXP3 and STAT3 interactions.
- Vitamin C holds potential as a therapeutic agent for ischemic stroke, warranting further clinical investigation.

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...
