Phosphorylated upstream frameshift 1-dependent nonsense-mediated μ opioid receptor mRNA decay in the spinal cord contributes to the development of neuropathic allodynia-like behavior in rats.

Nonsense-mediated mRNA decay increases targeted mRNA degradation and has been implicated in the regulation of gene expression in neurons. We hypothesized that nonsense-mediated μ opioid receptor mRNA decay in the […]

Flexible Organic-Inorganic Halide Perovskite-Based Diffusive Memristor for Artificial Nociceptors.

With the current evolution in the artificial intelligence technology, more biomimetic functions are essential to execute increasingly complicated tasks and respond to challenging work environments. Therefore, an artificial nociceptor plays […]

Mouse models of surgical and neuropathic pain produce distinct functional alterations to prodynorphin expressing neurons in the prelimbic cortex.

The medial prefrontal cortex (mPFC) consists of a heterogeneous population of neurons that respond to painful stimuli, and our understanding of how different pain models alter these specific mPFC cell […]

Astrocytic purinergic signaling contributes to the development and maintenance of neuropathic pain via modulation of glutamate release.

Although activation of astrocytes is critical in developing neuropathic pain (NP) following nerve injury, the underlying mechanisms of NP and therapeutic management for NP are still vague. Importantly, the decreases […]

Low-dose celecoxib-loaded PCL fibers reverse intervertebral disc degeneration by up-regulating CHSY3 expression.

Intervertebral disc degeneration (IDD) has been identified as one of the predominant factors leading to persistent low back pain and disability in middle-aged and elderly people. Dysregulation of Prostaglandin E2 […]

Low-Dose Δ9-THC Produces Antinociception in Female, But Not Male Rats.

The analgesic effects of delta-9-tetrahydrocannabinol (THC), the primary psychoactive compound in cannabis, have been widely promoted. Unfortunately, animal research is limited by the use of high doses and pain-evoked tests. […]

Morphine-induced mechanical hypersensitivity in mice requires δ receptors, β-arrestin2 and c-Src activity.

Morphine diminishes pain, but its long-term use is compromised by tolerance and hyperalgesia. Studies implicate δ receptors, β-arrestin2 and Src kinase in tolerance. We examined whether these proteins are also […]

Anxiety-related behaviors without observation of generalized pain in a mouse model of endometriosis.

Endometriosis is a chronic, hormone-dependent, inflammatory disease, characterized by the presence and growth of endometrial tissue outside the uterine cavity. It is associated with moderate to severe pelvic and abdominal […]

Design, Synthesis, and Biological Evaluation of the First Radio-Metalated Neurotensin Analogue Targeting Neurotensin Receptor 2.

Neurotensin receptor 2 (NTS) is a well-known mediator of central opioid-independent analgesia. Seminal studies have highlighted NTS overexpression in a variety of tumors including prostate cancer, pancreas adenocarcinoma, and breast […]

Identification of the molecular determinants of antagonist potency in the allosteric binding pocket of human P2X4.

P2X receptors are a family of ATP-gated cation channels comprising seven subtypes in mammals, which play key roles in nerve transmission, pain sensation and inflammation. The P2X4 receptor in particular […]
