Cross-trait analyses identify shared genetics between migraine, headache, and glycemic traits, and a causal relationship with fasting proinsulin.

The co-occurrence of migraine and glycemic traits has long been reported in observational epidemiological studies, but it has remained unknown how they are linked genetically. We used large-scale GWAS summary […]

Activation of the High-Affinity Choline Transporter 1 in the Spinal Cord Relieves Stress-Induced Hyperalgesia.

The mechanism underlying irritable bowel syndrome (IBS), a common disease with hyperalgesia, remains elusive. The spinal cholinergic system is involved in pain modulation, but its role in IBS is unknown.

Characterization of Fragile X Mental Retardation Protein expression in human nociceptors and their axonal projections to the spinal dorsal horn.

Fragile X Mental Retardation Protein (FMRP) regulates activity-dependent RNA localization and local translation to modulate synaptic plasticity throughout the central nervous system. Mutations in the FMR1 gene that hinder or […]

Metabotropic glutamate receptor 5-mediated inhibition of inward-rectifying K channel 4.1 contributes to orofacial ectopic mechanical allodynia following inferior alveolar nerve transection in male mice.

Inward-rectifying K channel 4.1 (Kir4.1), which regulates the electrophysiological properties of neurons and glia by affecting K homeostasis, plays a critical role in neuropathic pain. Metabotropic glutamate receptor 5 (mGluR5) […]

The roles of periaqueductal gray and dorsal raphe nucleus dopaminergic systems in the mechanisms of thermal hypersensitivity and depression in mice.

Depression and thermal hypersensitivity share pathogenic features and symptomology, but their pathophysiologic interactions have not been fully eluidated. Dopaminergic systems in the ventrolateral periaqueductal gray and dorsal raphe nucleus have […]

Drosophila pain sensitization and modulation unveiled by a novel pain model and analgesic drugs.

In mammals, pain is regulated by the combination of an ascending stimulating and descending inhibitory pain pathway. It remains an intriguing question whether such pain pathways are of ancient origin […]

Neuronal NLRP3 inflammasome mediates spreading depolarization-evoked trigeminovascular activation.

Spreading depolarization (SD), the underlying mechanism of migraine aura, may trigger the opening of the Pannexin-1 (Panx1) pore to sustain the cortical neuroinflammatory cascades involved in the genesis of headache. […]
