No evidence for cognitive impairment in an experimental rat model of knee osteoarthritis and associated chronic pain.

Although chronic pain states have been associated with impaired cognitive functions, including memory and cognitive flexibility, the cognitive effects of osteoarthritis (OA) pain remain to be clarified. The aim of […]

Small extracellular vesicles from spared nerve injury model and sham control mice differentially regulate gene expression in primary microglia.

Nerve injury outcomes might be predicted by examining small extracellular vesicles (sEVs) in circulation, as their biomolecular cargo facilitates cellular communication and can alter transcriptional state and behavior of recipient […]

Scalable generation of sensory neurons from human pluripotent stem cells.

Development of new non-addictive analgesics requires advanced strategies to differentiate human pluripotent stem cells (hPSCs) into relevant cell types. Following principles of developmental biology and translational applicability, here we developed […]

Dexmedetomidine alleviates osteoarthritis inflammation and pain through the CB pathway in rats.

As a common joint disease, osteoarthritis (OA) is often associated with chronic pain. Synovial inflammation is correlated with OA progression and pain. Synovial inflammation can produce a series of destructive […]

Preparation of Primary Mixed Glial Cell Cultures from Adult Mouse Spinal Cord Tissue.

Central nervous system glial cells are known to mediate many neurocognitive/neurodegenerative diseases, including Alzheimer’s and Parkinson’s diseases. Similar glial responses have been recognized as critical factors contributing to the development […]

Multi-Region Microdialysis Imaging Platform Revealed Dorsal Raphe Nucleus Calcium Signaling and Serotonin Dynamics during Nociceptive Pain.

In this research, we combined our ultralight micro-imaging device for calcium imaging with microdialysis to simultaneously visualize neural activity in the dorsal raphe nucleus (DRN) and measure serotonin release in […]

Involvement of ASIC3 and substance P in therapeutic ultrasound-mediated analgesia in mouse models of fibromyalgia.

Therapeutic ultrasound (tUS) is widely used in chronic muscle pain control. However, its analgesic molecular mechanism is still not known. Our objective is to reveal the mechanism of the tUS-induced […]

Studies on diketopiperazine and dipeptide analogs as opioid receptor ligands.

Using the structure of gliotoxin as a starting point, we have prepared two different chemotypes with selective affinity to the kappa opioid receptor (KOR). Using medicinal chemistry approaches and structure-activity […]

GABAergic neurons in the ventral lateral geniculate nucleus and intergeniculate leaflet are involved in itch processing in mice.

Itch and pain are two closely related sensations that receiving similar encodings at multiple levels. Accumulated evidences suggest that activation of the ventral lateral geniculate nucleus and intergeniculate leaflet (vLGN/IGL)-to-lateral […]

Chronic alcohol induced mechanical allodynia by promoting neuroinflammation: a mouse model of alcohol-evoked neuropathic pain.

Unrelieved chronic pain is considered a key factor contributing to the maintenance of alcohol use disorder (AUD). The mechanisms responsible for chronic pain associated with chronic alcohol consumption are still […]
