Activation of G-protein-coupled receptor 183 initiates inflammatory pain via macrophage CCL22 secretion.

Chronic pain is a major public health problem with limited effective therapeutic options. G-protein-coupled receptors play a significant role in pain modulation; however, whether and how G-protein-coupled receptor 183 participates […]

ARTEMIN SENSITIZES NOCICEPTORS THAT INNERVATE THE OSTEOARTHRITIC JOINT TO PRODUCE PAIN.

There have been significant developments in understanding artemin/GFRα3 signaling in recent years, and there is now accumulating evidence that artemin has important roles to play in pain signaling, including that […]

The Role of the Male Rat Infralimbic Cortex in Distraction Analgesia.

Cognitive interventions, including distraction, have been successfully utilized in the manipulation of experimental pain and the treatment of clinical pain. Attentional diversions can reduce the experience of pain, a phenomenon […]

A neural circuit for regulating a behavioral switch in response to prolonged uncontrollability in mice.

Persistence in the face of failure helps to overcome challenges. But the ability to adjust behavior or even give up when the task is uncontrollable has advantages. How the mammalian […]

Nav1.7 is essential for nociceptor action potentials in the mouse in a manner independent of endogenous opioids.

Loss-of-function mutations in Nav1.7, a voltage-gated sodium channel, cause congenital insensitivity to pain (CIP) in humans, demonstrating that Nav1.7 is essential for the perception of pain. However, the mechanism by […]

Detection of brain regions responsible for chronic pain in osteoarthritis: an fMRI-based neuroimaging study using deep learning.

Chronic pain is a multifaceted condition that has yet to be fully comprehended. It is frequently linked with a range of disorders, particularly osteoarthritis (OA), which arises from the progressive […]

PAG neuronal NMDARs activation mediated morphine-induced hyperalgesia by HMGB1-TLR4 dependent microglial inflammation.

Morphine is one of the most effective and widely used analgesic drugs. However, chronic morphine use caused opioid-induced hyperalgesia (OIH). The development of OIH limits the use of morphine. The […]

Developing a 3-D computational model of neurons in the central amygdala to understand pharmacological targets for pain.

Neuropathic and nociplastic pain are major causes of pain and involve brain areas such as the central nucleus of the amygdala (CeA). Within the CeA, neurons expressing protein kinase c-delta […]

Brainstem modulation of nociception by periaqueductal gray neurons expressing the mu-opioid receptor in mice.

Pharmacological manipulations directed at the periaqueductal gray have demonstrated the importance of the mu-opioid receptor in modulating reflexive responses to nociception. We hypothesized that a supraspinal pathway centered on neurons […]
