Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

open access: yesAdvanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

Remote Ischemic Post‐Conditioning Preserves the Neurovascular Unit by Brain‐Derived Gas6 That Drives Monocyte‐Derived Macrophage Reprogramming via Axl and Vimentin after SAH

open access: yesAdvanced Science, EarlyView.
Subarachnoid hemorrhage (SAH) triggers monocyte‐derived macrophage (MDM) infiltration and M1‐like polarization via Vimentin upregulation, leading to neurovascular unit disruption and cognitive dysfunction. Remote ischemic postconditioning (RIPostC) upregulates neuronal Gas6, which activates Axl on MDMs to downregulate Vimentin and drive reparative M2 ...

In Situ Photo‑Crosslinked Functional Bilayer Hydrogel Modulates Local Microenvironment and Remyelination After Optic Nerve Injury

open access: yesAdvanced Science, EarlyView.
A blue‐light‐crosslinked bilayer hydrogel was developed for local optic nerve repair. The adhesive GM‐Odex outer layer seals and anchors the lesion, while the non‐adhesive GM‐imid inner layer releases MPDA‐Cle without obstructing CSF flow. This system modulates oxidative and inflammatory microenvironments, supports oligodendrocyte differentiation and ...

Chronic hindlimb ischemia exacerbates ischemic stroke by disrupting cerebral hemodynamics and glycerophospholipid metabolism in mice

open access: yesScientific Reports
While clinical data firmly establish that Peripheral artery disease is linked to a higher incidence and severity of ischemic stroke, the underlying hemodynamics and metabolic mechanisms remain poorly defined.

Chronic critical limb ischemia: European experiences

open access: yes, 2009
Chronic critical limb ischemia still poses a substantial threat to both limb and life of the affected patients since these patients suffer typically also from associated cardiac and cerebrovascular disease and other severe comorbidities.

H4K12 Lactylation Regulates NDUFS7 to Drive Microglia Reverse Electron Transport in Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Lactate accumulation after SCI promotes H4K12la lactylation, which upregulates NDUFS7, triggering mitochondrial RET and ROS, enforcing pro‐inflammatory microglial polarization. MM@mPTC, a biomimetic nanotherapeutic, degrades LDHA in activated microglia, reducing H4K12la lactylation and blocking RET, thus curbing ROS, fostering a reparative phenotype ...

Lactate Signal: Modulator of Cellular Energy Production and Anabolism

open access: yesAdvanced Science, EarlyView.
Compartmentalized lactate signaling provides a spatial framework for understanding how lactate‐rich states are generated, transported, sensed, and translated into biological outputs. This Review integrates extracellular, cytosolic, mitochondrial‐associated, and nuclear lactate mechanisms to explain how lactate shapes metabolic adaptation, immune ...

From the pathogenesis of chronic cerebral ischemia to targeted therapy [PDF]

open access: yes
Chronic progressive cerebrovascular pathology is a powerful disabling factor in modern society. Chronic cerebral ischemia is based on microcirculation and neuroinflammation problems, which are mutually potentiating pathogenetic aspects.

Cellular Mechanisms Enabling Mitochondria Transfer and Transplantation

open access: yesAdvanced Science, EarlyView.
Mitochondrial transfer and transplantation (mitoTT) is examined as a multistep process governed by distinct transfer routes and post‐transfer checkpoints. Mechanisms controlling mitochondrial uptake, network integration, cristae remodeling, mtDNA maintenance, immune sensing, and quality control are highlighted, revealing key biological and ...

Brain glutamine synthetase increases following cerebral ischemia in the rat

open access: yes, 1992
Changes in astrocyte glutamine synthetase (GS) in postischemic rat brain were evaluated and correlated with regional neuronal vulnerability or resistance to ischemia. Rats subjected to 20 or 30 min of cerebral ischemia were allowed to survive for 3 or 24
