An Olfactory Piriform Cortex‐Lateral Hypothalamus Neural Circuit Contributes to Linalool‐Induced Analgesia

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
Linalool odor exposure activates a glutamatergic projection from the piriform cortex to the lateral hypothalamus (PiriGlu‐LH), mediating descending inhibitory pain pathways. This demonstrates a novel neural mechanism for olfactory‐induced pain modulation and suggests potential therapeutic implications for pain management.

Heart‐Specific Spinal and Vagal Afferents: Transcriptomic Signatures and Optogenetically Modulated Functional Coupling With Cardiomyocytes

open access: yesComprehensive Physiology, Volume 16, Issue 4, August 2026.
Selective purification of heart‐specific spinal and vagal sensory neurons by retrograde labeling and FACS purification showed enhanced spontaneous, optogenetic, and chemically stimulated Ca2+ activity. Transcriptomic profiling identified distinct ion channel and GPCR signatures in heart‐specific sensory neurons.

Astrocytic mGluR5 Regulation of Synaptic Transmission is Activity‐Dependent in Adult Rats

open access: yesGlia, Volume 74, Issue 8, August 2026.
In adulthood, astrocytic mGluR5 increases synaptic efficacy through presynaptic A2ARs. This occurs when a small number of synapses are activated simultaneously. This pathway is abolished when numerous synapses are recruited. ABSTRACT Data accumulated over the last two decades have demonstrated that astrocytes play key roles in the regulation of ...

Recent research progress in tetrodotoxin detection and quantitative analysis methods

open access: yesFrontiers in Chemistry
Tetrodotoxin (TTX) is a highly potent and widely distributed ion-channel marine neurotoxin; it has no specific antidote and poses a great risk to human health.

Nucleotide Metabolism in Health and Disease

open access: yesMedComm, Volume 7, Issue 8, August 2026.
Nucleotide metabolism, including de novo synthesis, salvage pathways, and catabolism, when dysregulated contributes to cancer, immune disorders, metabolic and urological diseases, and radiation injury. Metabolites such as adenosine, cGAMP, NAD, and cAMP and enzymes like RNR are promising therapeutic targets and biomarkers.

The Role of Thyroidectomy in the Management of Thyroglossal Duct Carcinoma: A Systematic Review

open access: yesOtolaryngology–Head and Neck Surgery, Volume 175, Issue 2, Page 271-280, August 2026.
Abstract Objective The extent of surgical management of thyroglossal duct‐associated differentiated thyroid carcinoma remains controversial. This study aims to evaluate the role of total thyroidectomy in patients with thyroglossal duct‐associated differentiated thyroid carcinoma and provide insights to support individualized, evidence‐based care.

Adaptive evolution of scn4aa in Takifugu and Tetraodon

open access: yesAquaculture and Fisheries
Tetrodotoxin (TTX) is a potent neurotoxin firstly discovered in the ovary of pufferfish. The genetic basis of voltage-gated sodium channel resistance to TTX has been widely studied, but it remains unclear in the evolution history of voltage-gated sodium ...

Pufferfish exposure and presumed tetrodotoxicosis in Australian dogs: 372 cases (2007–2018)

open access: yesAustralian Veterinary Journal, Volume 104, Issue 8, Page 497-508, August 2026.
Introduction Tetrodotoxin (TTX) is a neurotoxin found in pufferfish that results in the blockade of excitatory conduction and clinical signs including gastrointestinal upset and paralysis. The objectives of this study were to describe the epidemiology of pufferfish exposure and presumed tetrodotoxicosis in dogs, and to determine associations with the ...

Memantine prevents acute stress‐induced memory deficits by reversing sex‐dependent pathophysiological glutamatergic alterations in the dorsal hippocampus

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 16, Page 4939-4952, August 2026.
Abstract Background and Purpose The neural mechanisms underlying effects of acute stress on memory are poorly understood. We demonstrated previously that acute stress produces identical spatial memory deficits in male and female mice but through distinct molecular mechanisms, with females exhibiting up‐regulation of N‐methyl‐D‐aspartate (NMDA) receptor

Endothelium‐ and epithelium‐derived novel endogenous catecholamines as modulators of the autonomic nervous system

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 15, Page 4091-4110, August 2026.
Abstract Catecholamines are classically viewed as neuronal transmitters and adrenal hormones; however, accumulating evidence demonstrates that sources other than nerve fibres and adrenal medulla play a fundamental role in local organ regulation. Physiological paradoxes, such as preserved organ function after denervation or transplantation, challenge a ...
