Description

Molecular Mechanism and Rationale

The proposed therapeutic approach centers on the fundamental understanding that vocal cord dysfunction represents an early manifestation of brainstem neurodegeneration, specifically involving the vagal motor complex and its downstream effector pathways. The recurrent laryngeal nerve, a branch of the vagus nerve (cranial nerve X), innervates the intrinsic laryngeal muscles responsible for vocal cord adduction, abduction, and tension regulation. Degeneration of the dorsal motor nucleus of the vagus (DMV) and nucleus ambiguus, which contains the preganglionic motor neurons controlling laryngeal function, occurs early in neurodegenerative diseases including Parkinson's disease, amyotrophic lateral sclerosis (ALS), and multiple system atrophy.

The impact of acupuncture on neuroplasticity after ischemic stroke: a literature review and perspectives. MEDIUM
Front Cell Neurosci · 2022 · PMID:36439200 · Q:0.00
ABSTRACT

Ischemic stroke is common in the elderly, and is one of the main causes of long-term disability worldwide. After ischemic stroke, spontaneous recovery and functional reconstruction take place. These processes are possible thanks to neuroplasticity, which involves neurogenesis, synaptogenesis, and angiogenesis. However, the repair of ischemic damage is not complete, and neurological deficits develop eventually. The WHO recommends acupuncture as an alternative and complementary method for the treatment of stroke. Moreover, clinical and experimental evidence has documented the potential of acupuncture to ameliorate ischemic stroke-induced neurological deficits, particularly sequelae such as dyskinesia, spasticity, cognitive impairment, and dysphagia. These effects are related to the ability of acupuncture to promote spontaneous neuroplasticity after ischemic stroke. Specifically, acupuncture can stimulate neurogenesis, activate axonal regeneration and sprouting, and improve the structure

Ultrasound-Triggered NO Release to Promote Axonal Regeneration for Noise-Induced Hearing Loss Therapy. MEDIUM
ACS Nano · 2024 · PMID:39561026 · Q:0.00
ABSTRACT

Intense noise poses a threat to spiral ganglion neurons (SGNs) in the inner ear, often resulting in limited axonal regeneration during noise injury and leading to noise-induced hearing loss (NIHL). Here, we propose an ultrasound-triggered nitric oxide (NO) release to enhance the sprouting and regeneration of injured axons in SGNs. We developed hollow silicon nanoparticles to load nitrosylated N-acetylcysteine, producing HMSN-SNO, which effectively protects NO from external interferences. Utilizing low-intensity ultrasound stimulation with bone penetration, we achieve the controlled release of NO from HMSN-SNO within the cochlea. In mice with NIHL, a rapid and extensive loss of synaptic connections between hair cells and SGNs is observed within 24 h after exposure to excessive noise. However, this loss could be reversed with the combined treatment, resulting in a hearing functional recovery from 83.57 to 65.00 dB SPL. This positive outcome is attributed to the multifunctional effects of

Electrical Stimulation: How It Works and How to Apply It. MEDIUM
Hand Clin · 2024 · PMID:38972685 · Q:0.00
ABSTRACT

Electrical stimulation is emerging as a perioperative strategy to improve peripheral nerve regeneration and enhance functional recovery. Despite decades of research, new insights into the complex multifaceted mechanisms of electrical stimulation continue to emerge, providing greater understanding of the neurophysiology of nerve regeneration. In this study, we summarize what is known about how electrical stimulation modulates the molecular cascades and cellular responses innate to nerve injury and repair, and the consequential effects on axonal growth and plasticity. Further, we discuss how electrical stimulation is delivered in preclinical and clinical studies and identify knowledge gaps that may provide opportunities for optimization.

Advances in sciatic nerve regeneration: A review of contemporary techniques. MEDIUM
Regen Ther · 2025 · PMID:40475697 · Q:0.00
ABSTRACT

Sciatic nerve injury, affecting the longest and thickest nerve in the human body, often leads to severe pain, weakness, and impaired motor function in the lower extremities. Despite the peripheral nervous system's inherent capacity for some degree of regeneration, complete recovery remains elusive, necessitating advanced therapeutic approaches. This review explores two promising modalities electrical stimulation (ES) and platelet-rich plasma (PRP) that have shown the potential to enhance nerve repair and functional recovery. ES, through techniques such as transcutaneous electrical nerve stimulation (TENS), neuromuscular electrical stimulation (NMES), and direct current stimulation (DCS), facilitates neuronal regeneration by guiding axonal growth, releasing neurotrophic factors, and promoting synaptic plasticity. PRP, derived from autologous blood, is rich in growth factors such as Platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), and nerve growth factor

Role of BDNF-TrkB signaling in the improvement of motor function and neuroplasticity after ischemic stroke in rats by transcranial direct current stimulation.
Brain Res Bull · 2025 · PMID:39662631 · Q:0.00
ABSTRACT

BACKGROUND: Transcranial direct current stimulation (tDCS) has an impact on improving cognitive and motor dysfunction induced by ischemia-reperfusion injury. However, to use this technology more rationally in clinical practice, a deepened understanding of the molecular mechanisms behind its therapeutic effects is needed. This study explored the role of the brain-derived neurotrophic factor(BDNF) and its associated receptor tropomyosin-receptor kinase B(TrkB) while deciphering the underlying mechanisms in transcranial direct current therapy to treat ischemic stroke. METHODS: A middle cerebral artery occlusion-reperfusion(MCAO/R) model was established in rats to observe tDCS effects on brain damage. Behavioral tests, the modified neurologic severity score(mNSS), and the Hoffman reflex / the M wave(Hmax/Mmax) ratio helped assess motor function and neurologic deficits. HE and Nissl staining helped observe the morphological changes and count of nerve cells. We tested the expression of growt

Generation of Functional Human 3D Cortico-Motor Assembloids. MEDIUM
Cell · 2020 · PMID:33333020 · Q:0.00
ABSTRACT

Neurons in the cerebral cortex connect through descending pathways to hindbrain and spinal cord to activate muscle and generate movement. Although components of this pathway have been previously generated and studied in vitro, the assembly of this multi-synaptic circuit has not yet been achieved with human cells. Here, we derive organoids resembling the cerebral cortex or the hindbrain/spinal cord and assemble them with human skeletal muscle spheroids to generate 3D cortico-motor assembloids. Using rabies tracing, calcium imaging, and patch-clamp recordings, we show that corticofugal neurons project and connect with spinal spheroids, while spinal-derived motor neurons connect with muscle. Glutamate uncaging or optogenetic stimulation of cortical spheroids triggers robust contraction of 3D muscle, and assembloids are morphologically and functionally intact for up to 10 weeks post-fusion. Together, this system highlights the remarkable self-assembly capacity of 3D cultures to form functi

Enhancing Motor and Sensory Axon Regeneration after Peripheral Nerve Injury Using Bioluminescent Optogenetics. MEDIUM
Int J Mol Sci · 2022 · PMID:36555724 · Q:0.00
ABSTRACT

Introduction-Recovery from peripheral nerve injuries is poor even though injured peripheral axons can regenerate. Novel therapeutic approaches are needed. The most successful preclinical experimental treatments have relied on increasing the activity of the regenerating axons, but the approaches taken are not applicable to many nerve-injured patients. Bioluminescent optogenetics (BL-OG) is a novel method of increasing the excitation of neurons that might be similar to that found with activity-dependent experimental therapies. We investigated the use of BL-OG as an approach to promoting axon regeneration following peripheral nerve injury. Methods-BL-OG uses luminopsins, light-sensing ion channels (opsins) fused with a light-emitting luciferase. When exposed to a luciferase substrate, such as coelenterazine (CTZ), luminopsins expressed in neurons generate bioluminescence and produce excitation through their opsin component. Adeno-associated viral vectors encoding either an excitatory lumi

Neural Regen Res · 2026 · PMID:39995064 · Q:0.00
ABSTRACT

Optogenetics has revolutionized the field of neuroscience by enabling precise control of neural activity through light-sensitive proteins known as opsins. This review article discusses the fundamental principles of optogenetics, including the activation of both excitatory and inhibitory opsins, as well as the development of optogenetic models that utilize recombinant viral vectors. A considerable portion of the article addresses the limitations of optogenetic tools and explores strategies to overcome these challenges. These strategies include the use of adeno-associated viruses, cell-specific promoters, modified opsins, and methodologies such as bioluminescent optogenetics. The application of viral recombinant vectors, particularly adeno-associated viruses, is emerging as a promising avenue for clinical use in delivering opsins to target cells. This trend indicates the potential for creating tools that offer greater flexibility and accuracy in opsin delivery. The adaptations of these v

Cell Mol Neurobiol · 2025 · PMID:40715588 · Q:0.00
ABSTRACT

Recent developments in neural circuit mapping and neurotherapy are changing our understanding of the dynamic network structure of the brain and offering new treatment options. In many neurological and psychiatric diseases, targeted control of specific brain circuits has proven to be a successful strategy to reduce cognitive, behavioral, and motor abnormalities. Sophisticated retrograde tracing techniques, transcranial magnetic stimulation (TMS), chemogenetics, optogenetics, and other technologies have greatly improved our ability to outline, observe, and control neuronal circuits with remarkable accuracy. These sophisticated techniques have revealed crucial information on neuroplasticity, circuit remodeling following injury, and the therapeutic potential of neuromodulatory interventions. Disorders include depression, anxiety, stroke, and neurodegenerative diseases are treated using techniques such as optogenetic stimulation, chemogenetic activation, and non-invasive brain stimulation t

Nat Commun · 2025 · PMID:41027946 · Q:0.00
ABSTRACT

Peripheral nerve transfer is an effective surgical method in restoring motor functions of upper limb after peripheral nerve injuries. However, the outcome of individual function recovery is less predictable. It is crucial to access the long-term evaluation of function improvement. Here, we developed a fully implantable multisite optogenetic stimulation system, which is tailored for wireless, reprogrammable and long-term function evaluation of peripheral nerve plexus with sub nerve resolution. In Thy1-ChR2-EYFP mice, our system induced distinct compound muscle action potentials and forelimb movements when illuminating different nerve fascicles. Furthermore, we applied the system on a nerve transfer mice model after traumatic brain injury and discovered innervation pattern of the transferred and adjacent nerves to multiple muscles consecutively within 12 weeks after surgery. Our system enabled refined evaluation of electrophysiological and motor functions of peripheral nerve plexus, shin

Gene therapy for laryngeal paralysis. MEDIUM
Ann Otol Rhinol Laryngol · 2007 · PMID:17388235 · Q:0.00
ABSTRACT

OBJECTIVES: The surgical options for laryngeal paralysis only achieve static changes of vocal fold position. Laryngeal reinnervation procedures have had little impact on the return of dynamic laryngeal function. The development of a new treatment for laryngeal paralysis, aimed at the return of dynamic function and neurologic restoration and regeneration, is necessary. METHODS: To assess the possibility of gene therapy for laryngeal paralysis aiming for the return of dynamic laryngeal function, we investigated the therapeutic effects of gene therapy using rat laryngeal paralysis models. RESULTS: In a rat vagal nerve avulsion model, we transferred glial cell line-derived neurotrophic factor (GDNF) gene into the nucleus ambiguus using an adenovirus vector. Two and 4 weeks after the GDNF gene transfer, a significantly larger number of surviving motoneurons was observed. These neuroprotective effects of GDNF gene transfer were enhanced by simultaneous brain-derived neurotrophic factor gene

Sci Rep · 2016 · PMID:27558932 · Q:0.00
ABSTRACT

Recurrent laryngeal nerve (RLN) injury remains a challenge due to the lack of effective treatments. In this study, we established a new drug delivery system consisting of a tube of Heal-All Oral Cavity Repair Membrane loaded with laminin and neurotrophic factors and tested its ability to promote functional recovery following RLN injury. We created recombinant fusion proteins consisting of brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF) fused to laminin-binding domains (LBDs) in order to prevent neurotrophin diffusion. LBD-BDNF, LBD-GDNF, and laminin were injected into a collagen tube that was fitted to the ends of the transected RLN in rats. Functional recovery was assessed 4, 8, and 12 weeks after injury. Although vocal fold movement was not restored until 12 weeks after injury, animals treated with the collagen tube loaded with laminin, LBD-BDNF and LBD-GDNF showed improved recovery in vocalisation, arytenoid cartilage angles, compound

J Mater Sci Mater Med · 2020 · PMID:33130983 · Q:0.00
ABSTRACT

The objective of this paper is to investigate the possibility and efficacy of recurrent laryngeal nerve repair by transplantation of co-cultured Schwann cells and neural stem cells (NSCs) in laminin-chitosan-poly-lactic-co-glycolic acid (laminin-chitosan-PLGA) nerve conduits in rats. A laminin-chitosan-PLGA conduit was used in a rat recurrent laryngeal nerve transection model. The rat recurrent laryngeal nerve was dissected to generate a 5  mm defect. Then, a laminin-chitosan-PLGA nerve conduit with or without Schwann cells and NSCs in the lumen was transplanted into the defect. A total of 96 female rats were randomised into six groups: co-culture of NSCs and Schwann cells in the nerve conduit group (CO), Schwann cells only in the nerve conduit group (SC), neural stem cells only in the nerve conduit group (NSC-only), nerve conduit group (null), autologous nerve graft group (autograft) and sham operation group (sham). Regenerated nerves were evaluated by histological and functional asse

Laryngoscope · 2007 · PMID:17473692 · Q:0.00
ABSTRACT

OBJECTIVES/HYPOTHESIS: To assess the possibilities of restoring laryngeal sensation in an animal model by way of the internal branch of the superior laryngeal nerve (ibSLN) bilateral section and anastomosis to itself or to transposition nerves (i.e., lingual, glossopharyngeal, and great auricular nerves). STUDY DESIGN: Prospective study using New Zealand rabbits. METHODS: Six groups of rabbits were operated on and evaluated: healthy controls (n = 6); section without reinnervation (denervated group, n = 7); section and reinnervation with ibSLN (SLN-SLN group, n = 9); and section and anastomosis with the lingual nerve (lingual group, n = 7), the glossopharyngeal nerve (glossopharyngeal group, n = 6), and the great auricular nerve (GA group, n = 7). After 9 months, recovery of a laryngeal closure reflex was assessed by stimulation of the epiglottis and nerve anastomosis. RESULTS: Laryngeal sensation was restored in 14.3% in the denervated group, 66.6% in the SLN-SLN group, 71.4% in the li

Upper aerodigestive tract neurofunctional mechanisms: lifelong evolution and exercise. MEDIUM
Head Neck · 2011 · PMID:21910155 · Q:0.00
ABSTRACT

The transformation of the upper aerodigestive tract--oral cavity, pharynx, and larynx--serves the functions of eating, speaking, and breathing during sleeping and waking hours. These life-sustaining functions may be produced by a central neural sensorimotor system that shares certain neuroanatomic networks while maintaining separate neural functional systems and network structures. Current understanding of development, maturation, underlying neural correlates, and integrative factors are discussed in light of currently available imaging modalities and recently emerging interventions. Exercise and an array of additional treatments together seem to provide promising translational pathways for evidence-based innovation, novel habilitation, and rehabilitation strategies and delay, or even prevent neuromuscular decline cross-cutting functions and supporting quality of life throughout increasingly enduring lifespans.

Induced unilateral vocal fold paralysis and recovery rapidly modulate brain areas related to phonatory behavior: a case study.
J Voice · 2011 · PMID:21051193 · Q:0.00
ABSTRACT

BACKGROUND: Peripheral and behavioral effects of voice disorders are well documented in the literature; yet, there is little information regarding the central neural biomarkers and mechanisms underlying these disorders. Understanding the details of brain function changes in disordered voice production is a critical factor for developing better treatment strategies that result in more robust patient outcomes. OBJECTIVE: To examine a model of induced unilateral vocal fold paralysis (iUVFP) to demonstrate and characterize the form of activity changes within central mappings of the larynx to the induced paralysis. The induced paralysis model allowed the participant to serve as his or her own control when comparing baseline results of normal voice with results during the paralysis and subsequent recovery. STUDY DESIGN: Prospective, case-study design. METHODS: Functional magnetic resonance imaging was used to examine central laryngeal representations during three time points: pre-iUVFP, duri

Optogenetic control of nerve growth. MEDIUM
Sci Rep · 2015 · PMID:25982506 · Q:0.33
ABSTRACT

Due to the limited regenerative ability of neural tissue, a diverse set of biochemical and biophysical cues for increasing nerve growth has been investigated, including neurotrophic factors, topography, and electrical stimulation. In this report, we explore optogenetic control of neurite growth as a cell-specific alternative to electrical stimulation. By investigating a broad range of optical stimulation parameters on dorsal root ganglia (DRGs) expressing channelrhodopsin 2 (ChR2), we identified conditions that enhance neurite outgrowth by three-fold as compared to unstimulated or wild-type (WT) controls. Furthermore, optogenetic stimulation of ChR2 expressing DRGs induces directional outgrowth in WT DRGs co-cultured within a 10 mm vicinity of the optically sensitive ganglia. This observed enhancement and polarization of neurite growth was accompanied by an increased expression of neural growth and brain derived neurotrophic factors (NGF, BDNF). This work highlights the potential for i

Neuron type-specific optogenetic stimulation for differential stroke recovery in chronic capsular infarct. MEDIUM
Exp Mol Med · 2024 · PMID:38825647 · Q:0.33
ABSTRACT

Cortical neuromodulation (CNM) is widely used to promote recovery after stroke. Despite the beneficial results of CNM, the roles played by different neuron types in the effects of current CNM techniques are unable to be differentiated. Our aim was to use selective optogenetic cortical stimulation to explore how different subpopulations of neuronal cells contribute to poststroke recovery. We transduced the sensory-parietal cortex (SPC) of rats with CamKII-ChR2 (pyramidal neurons), PV-ChR2 (parvalbumin-expressing inhibitory neurons), or hSyn-ChR2 (pan-neuronal population) before inducing photothrombotic capsular infarct lesions. We found that selective stimulation of inhibitory neurons resulted in significantly greater motor recovery than stimulation of excitatory neurons or the pan-neuronal population. Furthermore, 2-deoxy-2-[18F] fluoro-D-glucose microPET (FDG-microPET) imaging revealed a significant reduction in cortical diaschisis and activation of the corticostriatal neural circuit,

Nanomedicine · 2015 · PMID:25680542 · Q:0.00
ABSTRACT

UNLABELLED: This work demonstrates the successful long-term transfection in vivo of a DNA plasmid vector in rat visual cortex neurons using the magnetofection technique. The transfection rates reached values of up to 97% of the neurons after 30days, comparable to those achieved by viral vectors. Immunohistochemical treatment with anti-EGFP antibodies enhanced the detection of the EYFP-channelrhodopsin expression throughout the dendritic trees and cell bodies. These results show that magnetic nanoparticles offer highly efficient and enduring in vivo high-rate transfection in identified neurons of an adult mammalian brain and suggest that the magnetotechnique facilitates the introduction of large functional genetic material like channelrhodopsin with safe non-viral vectors using minimally invasive approaches. FROM THE CLINICAL EDITOR: Gene therapy may be one of the treatment modalities for neurological diseases in the future. The use of viral transfection remains a concern due to restric

ABSTRACT

Skin sensitization is increasingly becoming a significant concern in the development of drugs and cosmetics due to consumer safety and occupational health problems. In silico methods have emerged as alternatives to traditional in vivo animal testing due to ethical and economic considerations. In this study, machine learning methods were used to build quantitative structure-activity relationship (QSAR) models on five skin sensitization data sets (GPMT, LLNA, DPRA, KeratinoSens, and h-CLAT), achieving effective predictive accuracies (correct classification rates of 0.688-0.764 on test sets). To address the complex mechanisms of human skin sensitization, the Dempster-Shafer theory was applied to merge multiple QSAR models, resulting in an evidence-based integrated decision model. Various evidence combinations and combination rules were explored, with the self-defined Q3 rule showing superior balance. The combination of evidence such as GPMT and KeratinoSens and h-CLAT achieved a correct c

Cell Death Dis · 2016 · PMID:27809305 · Q:0.00
ABSTRACT

Channelrhodopsin-2 (ChR2) has become a celebrated research tool and is considered a promising potential therapeutic for neurological disorders. While making its way into the clinic, concerns about the safety of chronic ChR2 activation have emerged; in particular as the high-intensity blue light illumination needed for ChR2 activation may be phototoxic. Here we set out to quantify for the first time the cytotoxic effects of chronic ChR2 activation. We studied the safety of prolonged illumination on ChR2(D156A)-expressing human melanoma cells as cancer cells are notorious for their resistance to killing. Three days of illumination eradicated the entire ChR2(D156A)-expressing cell population through mitochondria-mediated apoptosis, whereas blue light activation of non-expressing control cells did not significantly compromise cell viability. In other words, chronic high-intensity blue light illumination alone is not phototoxic, but prolonged ChR2 activation induces mitochondria-mediated ap

We have previously shown that neuroprotective effects of an adenoviral glial cell line-derived neurotrophic factor (GDNF) gene transfer on the lesioned adult rat motoneurons in the nucleus ambiguus. In the present study, we examined neuroprotective effects of adenoviral gene transfer of brain-derived neurotrophic factor (BDNF) or/and GDNF to motoneurons in nucleus ambiguus using an adult rat vagal nerve avulsion model. The animals avulsed and inoculated with adenoviral vectors encoding BDNF (AxCAmBDNFME) or/and GDNF (AxCAhGDNF) showed immunolabeling for BDNF or/and GDNF in the nucleus ambiguus on the treated side, respectively, and expression of virus-induced BDNF or/and GDNF mRNA transcripts in the brainstem tissue that contained the nucleus ambiguus of the treated side. The treatment with AxCAhGDNF or AxCAmBDNFME significantly prevented the loss of vagal motoneurons in comparison to the control; the protective effect of AxCAmBDNFME was greater than that of AxCAhGDNF.

Novel Therapeutic Hypotheses for Pre-Clinical Neurodegeneration

Hypothesis 1: Circadian-Synchronized Proteostasis Enhancement

Title: Chronotherapy-Based Protein Clearance Amplification

Description: Digital biomarkers revealing disrupted sleep-wake cycles and motor fluctuations indicate circadian dysregulation occurring years before clinical diagnosis. Precisely timed administration of autophagy enhancers and proteasome activators during optimal circadian windows could amplify endogenous protein clearance mechanisms. This approach leverages the natural circadian regulation of gly

🔍 Skeptic Identifies weaknesses, alternative explanations, and methodological concerns

Critical Evaluation of Novel Therapeutic Hypotheses

Hypothesis 1: Circadian-Synchronized Proteostasis Enhancement

Specific Weaknesses

  • Therapeutic window uncertainty: No evidence provided for optimal timing windows, which likely vary significantly between individuals and disease states
  • Drug delivery challenges: Assumes proteostasis enhancers can achieve therapeutic CNS concentrations at specific times without addressing pharmacokinetic constraints
  • Circadian disruption causality: Evidence shows correlation between circadian disruption and neurodegeneration, but causa

Druggability and Feasibility Assessment

Hypothesis 1: Circadian-Synchronized Proteostasis Enhancement

Revised Confidence: 0.45

Druggability Assessment

CLOCK/BMAL1 Targets:
  • Low druggability: Transcription factors are notoriously difficult to target directly
  • Alternative approach: Target upstream kinases (CK1δ/ε, GSK-3β) or nuclear hormone receptors (REV-ERBα/β)
ULK1 (Autophagy):
  • High druggability: Kinase with defined ATP-binding pocket
  • Existing chemical matter: Multiple tool compounds available
