Characterization of migraineurs presenting interictal widespread pressure hyperalgesia identified using a tender point count: a cross-sectional study

open access: yesThe Journal of Headache and Pain, 2017
Background Migraineurs exhibit pain hypersensitivity throughout the body during and between migraine headaches. Migraine is classified as a central sensitivity syndrome, typified by fibromyalgia showing widespread pressure hyperalgesia determined by a ...

Morphine-induced hyperalgesia involves mu opioid receptors and the metabolite morphine-3-glucuronide

open access: yesScientific Reports, 2017
Opiates are potent analgesics but their clinical use is limited by side effects including analgesic tolerance and opioid-induced hyperalgesia (OIH). The Opiates produce analgesia and other adverse effects through activation of the mu opioid receptor (MOR)

Nociceptin attenuates the escalation of oxycodone self-administration by normalizing CeA-GABA transmission in highly addicted rats. [PDF]

open access: yes, 2020
Approximately 25% of patients who are prescribed opioids for chronic pain misuse them, and 5 to 10% develop an opioid use disorder. Although the neurobiological target of opioids is well known, the molecular mechanisms that are responsible for the ...

Contemporary views on inflammatory pain mechanisms: TRPing over innate and microglial pathways. [PDF]

open access: yes, 2016
Tissue injury, whether by trauma, surgical intervention, metabolic dysfunction, ischemia, or infection, evokes a complex cellular response (inflammation) that is associated with painful hyperalgesic states.

Neurotrophins and hyperalgesia [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
Nerve growth factor (NGF), a member of the neurotrophin family, is crucial for survival of nociceptive neurons during development. Recently, it has been shown to play an important role in nociceptive function in adults. NGF is up-regulated after inflammatory injury of the skin.

EP2 receptor antagonism reduces peripheral and central hyperalgesia in a preclinical mouse model of endometriosis

open access: yesScientific Reports, 2017
Endometriosis is an incurable gynecological disorder characterized by debilitating pain and the establishment of innervated endometriosis lesions outside the uterus. In a preclinical mouse model of endometriosis we demonstrated overexpression of the PGE2-

Acute phenobarbital administration induces hyperalgesia: pharmacological evidence for the involvement of supraspinal GABA-A receptors

open access: yesBrazilian Journal of Medical and Biological Research, 2001
The aim of the present study was to determine if phenobarbital affects the nociception threshold. Systemic (1-20 mg/kg) phenobarbital administration dose dependently induced hyperalgesia in the tail-flick, hot-plate and formalin tests in rats and in the ...

An interleukin-33/ST2 signaling deficiency reduces overt pain-like behaviors in mice [PDF]

open access: yes, 2013
Interleukin (IL)-33, the most recent member of the IL family of cytokines, signals through the ST2 receptor. IL-33/ST2 signaling mediates antigen challenge-induced mechanical hyperalgesia in the joints and cutaneous tissues of immunized mice. The present

Consequences of altered eicosanoid patterns for nociceptive processing in mPGES-1-deficient mice [PDF]

open access: yes, 2007
Cyclooxygenase-2 (COX-2)-dependent prostaglandin (PG) E2 synthesis in the spinal cord plays a major role in the development of inflammatory hyperalgesia and allodynia. Microsomal PGE2 synthase-1 (mPGES-1) isomerizes COX-2-derived PGH2 to PGE2.
