A clindamycin acetylated derivative with reduced antibacterial activity inhibits articular hyperalgesia and edema by attenuating neutrophil recruitment, NF-κB activation and tumor necrosis factor-α production.

We recently demonstrated that clindamycin exhibits activities in acute and chronic models of pain and inflammation. In the present study, we investigated the effects of clindamycin and a clindamycin acetylated […]

NOS inhibition reverses TLR2-induced chondrocyte dysfunction and attenuates age-related osteoarthritis.

Osteoarthritis (OA) is a joint disease featuring cartilage breakdown and chronic pain. Although age and joint trauma are prominently associated with OA occurrence, the trigger and signaling pathways propagating their […]

Obesity and its chronic inflammation as pain potentiation factor in rats with osteoarthritis.

Obesity produces the accumulation of adipose tissue and a chronic inflammatory process, while osteoarthritis (OA) is also an inflammatory disorder.

Mu-opioid receptor selective superagonists produce prolonged respiratory depression.

Synthetic opioids are increasingly challenging to combat the opioid epidemic and act primarily at opioid receptors, chiefly the G protein-coupled receptor (GPCR) μ-opioid receptor (MOR), which signals through G protein-dependent […]

Spinal CBX2 contributes to neuropathic pain by activating ERK signaling pathway in male mice.

The deregulated spinal cord proteins induced by nerve injury are the key to neuropathic pain. Integrated transcriptome and translatome analyses can screen out deregulated proteins controlled by only post-transcriptional regulation. […]

Electroacupuncture Alleviates Neuropathic Pain by Suppressing Ferroptosis in Dorsal Root Ganglion via SAT1/ALOX15 Signaling.

Neuropathic pain affects globally about 7-10% of the general population. Electroacupuncture (EA) effectively relieves neuropathic pain symptoms without causing any side effects; however, the underlying molecular mechanisms remain unclear. We […]

Monoacylglycerol lipase protects the presynaptic cannabinoid 1 receptor from desensitization by endocannabinoids after persistent inflammation.

Cannabinoid-targeted pain therapies are increasing with the expansion of cannabis legalization, however, their efficacy may be limited by pain-induced adaptations in the cannabinoid system. Cannabinoid receptor subtype 1 (CB1Rs) inhibition […]

Chronic Alcohol Drinking Drives Sex-Specific Differences in Affective Behavior and Medial Prefrontal Cortex Activity in CRF1:Cre:Tdtomato Transgenic Rats.

In 2021, 131 million adult Americans reported drinking alcohol in the last month, despite the well-known consequences of alcohol consumption. While alcohol use disorders are associated with both mood and […]

Novel HS-Releasing Bifunctional Antihistamine Molecules with Improved Antipruritic and Reduced Sedative Actions.

Hydrogen sulfide (HS) is an endogenous gasotransmitter with anti-inflammatory actions that also reduces itching. To test whether a combination of an antihistamine with a HS donor has improved antipruritic efficacy, […]

Dexmedetomidine alleviates anxiety-like behaviors in female mice with musculoskeletal pain through SIRT1/p53 axis.

Musculoskeletal pain is the most common form of chronic pain. Anxiety increases pain intensity and appears to have a major impact on the prevalence and also disability of musculoskeletal pain […]
