Self‐Propelled HPB@Lip@AB Nanomotors Ameliorate Dry Eye Disease

open access: yesAdvanced Science, EarlyView.
A self‐propelled HPB@Lip@AB nanomotor system is developed for dry eye disease (DED) therapy, facilitating rapid penetration across ocular surface barriers while integrating hydrogen therapy with multi‐enzyme‐like antioxidant activity. The nanoplatform restores mitochondrial function, suppresses oxidative stress, inflammation, and apoptosis, and ...

Electroacupuncture Pretreatment Prevents Cognitive Impairment Induced by Cerebral Ischemia–Reperfusion via Adenosine A1 Receptors in Rats

open access: yesFrontiers in Aging Neuroscience, 2021
A previous study has demonstrated that pretreatment with electroacupuncture (EA) induces rapid tolerance to focal cerebral ischemia. In the present study, we investigated whether adenosine receptor 1 (A1 R) is involved in EA pretreatment-induced ...

SIRT5‐Mediated Desuccinylation of ACAA2 Protects Against Calcium Oxalate‐Induced Kidney Injury by Regulating Fatty Acid Oxidation to Suppress Mitochondrial Oxidative Injury and Ferroptosis

open access: yesAdvanced Science, EarlyView.
The SIRT5/ACAA2 axis maintains lipid metabolic homeostasis in RTECs by promoting ACAA2 desuccinylation and preserving its stability and enzymatic activity, thereby sustaining FAO and limiting PUFA and PUFA‐containing phospholipid accumulation. Under CaOx stress, SIRT5 downregulation impairs FAO, promotes oxidative stress and ferroptosis, and enhances ...

Spatial Transcriptomics Reveals a T Cell‐Mediated Microglial Activation Axis of Immune Checkpoint Inhibition‐Related Adverse Events in the Brain

open access: yesAdvanced Science, EarlyView.
Immune checkpoint inhibition (ICI) reshapes the hippocampal neuroimmune niche. Spatial transcriptomic profiling and human brain histological analyses identify neuroinflammation and altered neuronal and glial programs. Notably, T cell depletion prevents ICI‐driven microglial activation, establishing the T cell–microglia crosstalk axis as a driving ...

An Allosteric Modulator of the Adenosine A1 Receptor Improves Cardiac Function Following Ischaemia in Murine Isolated Hearts

open access: yesPharmaceuticals, 2013
The effect of an allosteric modulator of the adenosine A1 receptors was investigated using an ischaemia-reperfusion protocol in murine isolated hearts. Isolated hearts were perfused with Kreb-Henseleit solution gassed with carbogen gas (95% O2 and 5% CO2)

Mitochondrial Protection and Neural Repair via ROS‐Responsive Biomimetic Nanoparticles in Intracerebral Hemorrhage

open access: yesAdvanced Science, EarlyView.
A ROS‐responsive biomimetic nanoparticle platform co‐delivers DIDS and Mdivi‐1 to protect mitochondria and promote neural repair after intracerebral hemorrhage. By targeting LPAR1/VDAC1‐related mitochondrial dysfunction, the nanotherapy reduces oxidative injury, neuronal apoptosis, and blood‐brain barrier disruption, improving neurological recovery and

A1 adenosine receptor evoked Ca2+ signals in astrocytes

open access: yesCurrent Directions in Biomedical Engineering
In addition to neurons, glial cells make up the nervous system. These glial cells are divided into macroglial cells - including astrocytes - and microglial cells.

EphB1 Receptor Blockade Augments Morphine Antinociception via Inhibiting GRK2‐Mediated µ‐Opioid Receptor Internalization

open access: yesAdvanced Science, EarlyView.
Administration of opioids activates ephrinB2‐EphB1 receptor signaling. Activated EphB1 receptors induce GRK2‐mediated phosphorylation of MOR at Ser375, which initiates the internalization of MOR and reduces opioid antinociception at the behavioral level. ABSTRACT Opioids are the primary treatment for severe pain in clinical practice.
