The Impact of Sciatic Nerve Injury and Social Interactions Testing on Glucocorticoid Receptor Expression in Catecholaminergic Medullary Cell Populations.

Paradoxically, while acute pain leads to transiently elevated corticosterone, chronic pain does not result in persistently elevated corticosterone. In the sciatic nerve chronic constriction injury (CCI) model of chronic pain, […]

Glucocorticoids regulate lipid mediator networks by reciprocal modulation of 15-lipoxygenase isoforms affecting inflammation resolution.

Glucocorticoids (GC) are potent anti-inflammatory agents, broadly used to treat acute and chronic inflammatory diseases, e.g., critically ill COVID-19 patients or patients with chronic inflammatory bowel diseases. GC not only […]

Modeling of Transmembrane Domain and Full-Length TLRs in Membrane Models.

Toll-like receptors (TLRs), classified as pattern recognition receptors, have a primordial role in the activation of the innate immunity. In particular, TLR4 binds to lipopolysaccharides (LPS), a membrane constituent of […]

Screening of miR-15a-5p as a potential biomarker for intervertebral disc degeneration through RNA-sequencing.

Low back pain (LBP) is a prevalent clinical condition that imposes substantial economic burdens on society. Intervertebral disc degeneration (IVDD) is recognized as a major contributing factor to LBP. Recent […]

Serpina3n/serpina3 alleviates cyclophosphamide-induced interstitial cystitis by activating the Wnt/β-catenin signal.

Serpina3n/Serpina3 has been identified to be implicated in inflammatory diseases, but its role in interstitial cystitis/bladder pain syndrome (IC/BPS) remains unknown. Here, we aimed to reveal serpina3n/serpina3 role in IC/BPS […]

Ligand recognition and G protein coupling of the human itch receptor MRGPRX1.

MRGPRX1, a Mas-related GPCR (MRGPR), is a key receptor for itch perception and targeting MRGPRX1 may have potential to treat both chronic itch and pain. Here we report cryo-EM structures […]

Pharmacological characterisation of erenumab, Aimovig, at two CGRP responsive receptors.

Calcitonin gene-related peptide (CGRP) is involved in migraine pathophysiology. CGRP can signal through two receptors. The canonical CGRP receptor comprises the calcitonin receptor-like receptor (CLR) and receptor activity-modifying protein 1 […]

Compartmentalized primary cultures of dorsal root ganglion neurons to model peripheral pathophysiological conditions.

Neurosensory disorders such as pain and pruritus remain a major health problem greatly impacting the quality of life, and often increasing the risk of mortality. Current pre-clinical models to investigate […]

Structure activity relationships of 5-HT and 5-HT serotonin receptor antagonists: N, C2 and 5′-Modified (N)-methanocarba-adenosine derivatives.

(N)-Methanocarba adenosine derivatives were structurally modified to target 5-HT serotonin receptors as antagonists, predominantly containing branched N-alkyl groups. N-Dicycloalkyl-methyl groups, including their asymmetric variations, as well as 2-iodo, were found […]

The clinically-approved compounds, pramipexole and dexpramipexole, reverse chronic allodynia from sciatic nerve damage in mice, and alter IL-1β and IL-10 expression from immune cell culture.

During the onset of neuropathic pain from a variety of etiologies, nociceptors become hypersensitized, releasing neurotransmitters and other factors from centrally-projecting nerve terminals within the dorsal spinal cord. Consequently, glial […]
