Neuroimmune Microenvironment Reprogramming via Immuno‐piezoelectric Transducers for Synergistic Stem Cell Therapy in Traumatic Brain Injury

open access: yesAdvanced Materials, EarlyView.
A novel immuno‐piezoelectric transducer is innovatively developed. This device promotes neural stem cell (NSC) differentiation and maturation via ultrasound‐induced electrical stimulation and it amplifies the therapeutic efficacy of NSC in traumatic brain injury (TBI) by modulating the immune microenvironment. This piezoelectric transducer with “immune‐

Electrocatalytic Dehydrogenative Lactonization of Benzylic Alcohols: A Sustainable Access to Phthalides via N‐hydroxyphthalimide Mediation

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A mild, scalable electrocatalytic method for direct lactonization of benzylic alcohols to phthalides using N‐hydroxyphthalimide as a redox mediator is reported. This metal‐free process proceeds via a phthalimide‐N‐oxyl‐mediated hydrogen atom transfer mechanism, shows broad scope with good to excellent yields, and enables late‐stage functionalizations ...

Neuropeptide S [PDF]

open access: yesNeuron, 2004
Arousal and anxiety are behavioral responses that involve complex neurocircuitries and multiple neurochemical components. Here, we report that a neuropeptide, neuropeptide S (NPS), potently modulates wakefulness and could also regulate anxiety. NPS acts by activating its cognate receptor (NPSR) and inducing mobilization of intracellular Ca2+.

Synergistic Modulation of Microglial Polarization by Acteoside and Ferulic Acid via Dual Targeting of Nrf2 and RORγt to Alleviate Depression‐Associated Neuroinflammation

open access: yesAdvanced Science, EarlyView.
Machine‐learning‐directed phytochemical pair ACT/FA, administered at BDD's orthodox ratio, synergistically modulates microglial polarization via dual Nrf2/RORγt targeting to attenuate neuroinflammation and depressive behaviors. This concentration‐dependent synergism replicates the parent formula's efficacy while providing a mechanistic basis for ...

CGRP‐Loaded ROS‐Responsive Hydrogel Restores Neuro‐Angiogenic Signaling to Promote Bone Regeneration in Diabetes‐Associated Periodontitis

open access: yesAdvanced Science, EarlyView.
This study shows that diabetes damages sensory nerve fibers, especially CGRP‐positive ones, in the periodontium and disrupts autophagy in trigeminal ganglion neurons, affecting bone homeostasis by inhibiting type H vessel formation. To address this, CGRP@PVA/tsPBA hydrogels are developed to release CGRP in response to ROS, which binds to endothelial ...

Nociceptive Nerve‐Derived CGRP Exacerbates Uterine Fibrogenesis in Adenomyosis by Promoting CD140b+ CD146+ Fibroblast Differentiation

open access: yesAdvanced Science, EarlyView.
This study investigates adenomyosis fibrosis in relation to nociceptive nerves. Nociceptive nerve‐secreted CGRP promotes RAMP1hi CD140b+ CD146+ fibroblast differentiation into myofibroblasts through ERK activation, causing severe fibrosis. Rimegepant‐induced CGRP/RAMP1 signaling blockade alleviates fibrosis and restores fertility in a mouse model. This

Neuropeptides as Potential Biomarkers in Vascular Dementia

open access: yesJournal of Integrative Neuroscience
Neuropeptides are endogenous active substances within the central and peripheral nervous systems that play important roles in a wide range of brain functions, including metabolism, food intake, social behavior, reproduction, learning, sleep, and ...

The Emerging Role of Neuropeptides in Parkinson’s Disease

open access: yesFrontiers in Aging Neuroscience, 2021
Parkinson’s disease (PD), the second most common age-related neurodegenerative disease, results from the loss of dopamine neurons in the substantia nigra. This disease is characterized by cardinal non-motor and motor symptoms.

Thermosensory TRPV Heterotetramers Drive Seasonal Polyphenism: Molecular Basis of CcIav/CcNan‐PKCα‐AKH/AKHR Signaling in Pear Psyllid Morph Transition

open access: yesAdvanced Science, EarlyView.
At 2 5 °C, thermal activation initiates: i) CcIav/CcNan heterotetramer assembly → Ca2⁺ influx; ii) CcPKCα phosphorylation → AKH signaling potentiation; iii) CcAKH1 binding to membrane‐localized CcAKHR → energy mobilization (lipid catabolism/glycogenolysis) and vitellogenin transport via follicular patency; iv) Oocyte maturation → summer‐form nymph ...
