Discovery of (S)-flurbiprofen-based novel azine derivatives as prostaglandin endoperoxide synthase-II inhibitors: Synthesis, in-vivo analgesic, anti-inflammatory activities, and their molecular docking.

The anti-inflammatory and analgesic drugs currently used are associated with several adverse effects and found to be highly unsafe for long-term use. Currently, nineteen novel bis-Schiff base derivatives (1-19) of […]

Defective branched-chain amino acid catabolism in dorsal root ganglia contributes to mechanical pain.

Impaired branched-chain amino acid (BCAA) catabolism has recently been implicated in the development of mechanical pain, but the underlying molecular mechanisms are unclear. Here, we report that defective BCAA catabolism […]

Regulation of nociception threshold by norepinephrine through adrenergic α2 receptor in rat models of Parkinson’s disease.

The mechanism of pain symptoms in Parkinson’s disease (PD) is unclear. Norepinephrine (NE) regulates neuropathic pain through ascending and descending pathways. However, the loss of NE neurons in the brain […]

Activation of G-protein-coupled receptor 39 reduces neuropathic pain in a rat model.

Activated G-protein-coupled receptor 39 (GPR39) has been shown to attenuate inflammation by interacting with sirtuin 1 (SIRT1) and peroxisome proliferator-activated receptor-γ coactivator 1α (PGC-1α). However, whether GPR39 attenuates neuropathic pain […]

Adverse event profile of CGRP monoclonal antibodies: findings from the FDA adverse event reporting database.

Four CGRP Monoclonal Antibodies (mAbs) have been approved for migraine prophylaxis by the Food and Drug Administration (FDA) since 2018. However, there are concerns about the safety of these four […]

Spinal TAOK2 contributes to neuropathic pain via cGAS-STING activation in rats.

Thousand and one amino acid kinase 2 (TAOK2) is a member of the mammalian sterile 20 kinase family and is implicated in neurodevelopmental disorders; however, its role in neuropathic pain […]

Electrical matrix stimulation suppresses acute itch independently of activation of sleeping nociceptors.

Itch can be reduced by pain. Activation of sleeping nociceptors (CMi) is a crucial mechanism for the peripheral component of intense and long-lasting pain. Thus, activation of CMi might be […]

Complement proteins L-ficolin and M-ficolin are increased in axial spondyloarthritis patients and decrease after TNF-inhibitor treatment.

We have previously reported elevated levels of the complement lectin pathway proteins L-ficolin and H-ficolin in axial spondyloarthritis (axSpA) patients compared with healthy controls. The aim of this study was […]

Adolescent alcohol exposure produces sex-specific long-term hyperalgesia via changes in central amygdala circuit function.

Exposure to alcohol during adolescence produces many effects that last well into adulthood. Acute alcohol is analgesic and people living with pain report drinking alcohol to reduce pain, but chronic […]

Systematic review of topical interventions for the management of pain in chronic wounds.

Chronic wounds adversely affect quality of life. Pain is associated with chronic wounds, and its impact can vary according to wound aetiology, condition, and patient factors. This systematic review examined […]
