Reducing Extracellular Ca2+ Induces Adenosine Release via Equilibrative Nucleoside Transporters to Provide Negative Feedback Control of Activity in the Hippocampus

Frontiers in Neural Circuits, 2017
Neural circuit activity increases the release of the purine neuromodulator adenosine into the extracellular space leading to A1 receptor activation and negative feedback via membrane hyperpolarization and inhibition of transmitter release.

Yoda1‐Functionalized Nanozymes Coordinate Piezo1 Activation and Mitochondrial Protection to Reprogram the Diabetic Osteoimmune Micromilieu and Promote Vascularized Bone Repair

Advanced Science, EarlyView.
Diabetic bone defects remain a critical clinical challenge. A 3D‐printed BCPG‐MF@Y scaffold, embedding Yoda1‐functionalized manganese dioxide‐ferritin nanozymes, scavenges mtROS, suppresses the cGAS–STING pathway, and reverses cellular senescence, while Yoda1 activates Piezo1 to direct BMSCs fate to synergistically reprogram the osteoimmune ...

A computer generated model of adenosine receptors rationalising binding and selectivity of receptor ligands

, 1991
Computer graphic analyses on a broad spectrum of adenosine receptor ligands has shown that both the A1 and A2 adenosine receptors have three binding sites. The spatial relationship of these three binding sites has been defined.

Low‐Density Lipoprotein Receptor‐Targeted Biomimetic Nanoplatform Suppresses Glioblastoma Stemness and Remodels Antitumor Immunity via Dual Metabolic Disruption

Advanced Science, EarlyView.
A low‐density lipoprotein receptor‐oriented biomimetic nanoplatform couples brain‐tumor delivery with a mechanistically matched regorafenib‐erythrodiol combination. Concurrent disruption of autophagic nutrient salvage and cholesterol homeostasis collapses bioenergetic and signaling support, suppresses glioblastoma stemness, and promotes immunogenic ...

Pulsed Electromagnetic Fields: A Novel Attractive Therapeutic Opportunity for Neuroprotection After Acute Cerebral Ischemia

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Acute cerebral ischemia is characterized by several pathological processes evolving during time, which contribute to the final tissue damage. Secondary processes, such as prolonged inflammatory response, impaired mitochondrial function and oxidative stress, are responsible for the progression of brain injury to the peri‐infarct area,

PDHA1 Hyperactivation‐Mediated Glucose Metabolism Reprogramming Fuels Neutrophil NETosis and Promotes Acute Lung Injury

Advanced Science, EarlyView.
During NETosis, neutrophils shift metabolically toward enhanced OXPHOS and partially reduced glycolysis. This shift is driven by PDHA1 hyperactivity‐dependent selective metabolic reprogramming. The neutrophil‐targeted nanoparticle 3‑FP‑BSA NPs effectively inhibit NETosis and attenuate ALI.

Precision Nanomedicine for Traumatic Neural Injury: Functional Paradigms and Translational Frameworks

Advanced Science, EarlyView.
This review presents a pathology‐driven framework unifying nanomedicine across TBI, SCI, and PNI. Epidemiological evidence and comparative single‐cell transcriptomic reanalysis define shared pathological modules, injury‐specific effectors, and therapeutic bottlenecks. Six functional paradigms connect nanomaterial structure and biological fate to injury‐

Adenosine attenuates calcium paradox injury: role of adenosine A1 receptor

, 1995
The present study was conducted to test the hypothesis that adenosine attenuates the Ca2+ paradox (PD) injury via stimulation of adenosine A1 receptors linked to Gi proteins in the isolated rat heart.

A Fluorogenic Cysteine‐Tetrapeptide Tagging Strategy for Nonperturbative Protein Labeling and Protein–Ligand Interaction Tracking

Advanced Science, EarlyView.
A compact Phe‐Cys‐Pro‐Phe (FCPF) tag and an environment‐sensitive SBD‐Cl‐derived probe form a sequence‐selective fluorogenic pair for wash‐free live‐cell protein imaging. This minimally perturbing chemistry allows flexible insertion at termini or loops, produces strong fluorescence upon local microenvironment confinement, supports FRET‐assisted ...
