MAPK-ERK-CREB signaling pathway upregulates Nav1.6 in oxaliplatin-induced neuropathic pain in the rat.

The voltage-gated sodium channel subtype Nav1.6 is involved in the electrophysiological changes of primary sensory neurons that occur in oxaliplatin-induced neuropathic pain, but its regulatory mechanism remains unclear. In this […]

Oral difelikefalin reduces moderate-to-severe pruritus and expression of pruritic and inflammatory biomarkers in subjects with atopic dermatitis.

Pruritus is the most common and burdensome symptom of atopic dermatitis (AD). Pruritus-targeted treatments in AD are lacking, particularly for patients with milder skin disease.

Difelikefalin suppresses itch and reduces scratching independent of inflammation in a murine model of atopic dermatitis.

Therapies specifically targeting non-histaminergic pruritus are largely lacking. Difelikefalin (DFK) has been found to reduce itch in various chronic pruritic conditions, including atopic dermatitis (AD).

Sex and stress hormone dysregulation as clinical manifestations of hypothalamic function in migraine disorder: A meta-analysis.

Migraine is a leading cause of disability in young adults. It occurs more frequently in females, often comorbidly with stress disorders, suggesting an association with hypothalamic sex and stress hormonal […]

The G protein-coupled estrogen receptor of the trigeminal ganglion regulates acute and chronic itch in mice.

Itch is an unpleasant sensation that severely impacts the patient’s quality of life. Recent studies revealed that the G protein-coupled estrogen receptor (GPER) may play a crucial role in the […]

Modulation of SK channels via calcium buffering tunes intrinsic excitability of parvalbumin interneurons in neuropathic pain: A computational and experimental investigation.

Parvalbumin-expressing interneurons (PVINs) play a crucial role within the dorsal horn of the spinal cord by preventing touch inputs from activating pain circuits. In both male and female mice, nerve […]

mGluR5 from primary sensory neurons promotes opioid-induced hyperalgesia and tolerance by interacting with and potentiating synaptic NMDA receptors.

Aberrant activation of presynaptic NMDA receptors (NMDARs) in the spinal dorsal horn is integral to opioid-induced hyperalgesia and analgesic tolerance. However, the signaling mechanisms responsible for opioid-induced NMDAR hyperactivity remain […]

Parabrachial nucleus activity in nociception and pain in awake mice.

The parabrachial nuclear complex (PBN) is a nexus for aversion, and for the sensory and affective components of pain perception. We have previously shown that, during chronic pain, PBN neurons […]

Hydrogel device for analgesic drugs with in-situ loading and polymerization.

The high prevalence of opioid addiction and the shortcomings of systemic opioids has increased the pace of the search for alternative methods of pain management. The local delivery of pain […]

Serum Biomarkers of Nociceptive and Neuropathic Pain in Chronic Pancreatitis.

Debilitating abdominal pain is a common symptom affecting most patients with chronic pancreatitis (CP). There are multiple underlying mechanisms that contribute to pain which makes successful treatment difficult. The identification […]
