Catechol-O-methyltransferase inhibition alters pain and anxiety-related volitional behaviors through activation of β-adrenergic receptors in the rat.

TLDR
Findings provide the first evidence that stimulation of βARs following acute or chronic COMT inhibition drives cognitive-affective behaviors associated with heightened pain that affects multiple body sites.

Neuroinflammation and Central Sensitization in Chronic and Widespread Pain

TL;DR: Neuroinflammation drives widespread chronic pain via central sensitization and sex-dependent glial/immune signaling in chronic pain and new therapeutic approaches that control neuroinflammation for the resolution of chronic pain are discussed.
Journal ArticleDOI

Sustained stimulation of β2- and β3-adrenergic receptors leads to persistent functional pain and neuroinflammation.

TL;DR: The results suggest that therapies that resolve neuroinflammation may prove useful in the management of functional pain syndromes, as sustained 14-day delivery of the COMT inhibitor OR486 leads to mechanical hypersensitivity that persists for at least 3 weeks after OR486 cessation.

Catechol-O-Methyltransferase (COMT): An Update on Its Role in Cancer, Neurological and Cardiovascular Diseases.

TL;DR: The role of COMT function and its involvement in cardiovascular and neurological disorders is updated and its role in the neurobiology of cognition, behaviour, emotions, pain processing and perception, sleep regulation, addictive behaviour and neurodegeneration is reviewed.

Persistent Catechol-O-methyltransferase–dependent Pain Is Initiated by Peripheral β-Adrenergic Receptors

TL;DR: Peripheral adrenergic input is necessary for the development of persistent COMT-dependent pain, and peripherally-acting &bgr;AR antagonists may benefit chronic pain patients.
Journal ArticleDOI

Manganese-enhanced MRI reveals changes within brain anxiety and aversion circuitry in rats with chronic neuropathic pain- and anxiety-like behaviors

TL;DR: The findings support use of MEMRI and chronic rodent models for preclinical studies and therapeutic trials to reveal brain sites activated only after neuropathic pain has persisted in timeframes relevant to clinical pain and to observe treatment effects not possible in short-term models which do not have evidence of anxiety-like behaviors.

The induction of pain: an integrative review

TL;DR: A global account of mechanisms involved in the induction of pain is provided, including neuronal pathways for the transmission of nociceptive information from peripheral nerve terminals to the dorsal horn, and therefrom to higher centres.

Cloning of the gene and cDNA for mammalian β -adrenergic receptor and homology with rhodopsin

TL;DR: Cloning of the gene and cDNA for the mammalian β2AR indicates significant amino-acid homology with bovine rhodopin and suggests that, like rhodopsin7, βAR possesses multiple membrane-spanning regions.

Pain intensity processing within the human brain : a bilateral, distributed mechanism

TL;DR: Results confirm the existence of a highly distributed, bilateral supraspinal mechanism engaged in the processing of pain intensity and conserve pain intensity information across multiple, functionally distinct brain areas.

Catechol-O-methyltransferase-deficient mice exhibit sexually dimorphic changes in catecholamine levels and behavior

TL;DR: The results provide conclusive evidence for an important sex- and region-specific contribution of COMT in the maintenance of steady-state levels of catecholamines in the brain and suggest a role for comT in some aspects of emotional and social behavior in mice.

Q1. What are the contributions in "Catechol-o-methlytransferase inhibition alters pain and anxiety- related volitional behaviors through activation of β-adrenergic receptors in the rat" ?

In order to more closely mimic the characteristics of human chronic pain conditions associated with prolonged reductions in COMT, the present study sought to determine volitional pain-related and anxiety-like behavioral responses following sustained as well as acute COMT inhibition using an operant 10–45°C thermal place preference task and a light/dark preference test. Collectively, these findings provide the first evidence that stimulation of ARs following acute or chronic COMT inhibition drives cognitive-affective behaviors associated with heightened pain that affects multiple body sites. This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to their customers the authors are providing this early version of the manuscript. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Further, sustained administration of OR486 increased anxiety behavior in response to bright light, as well as abdominal mechanosensation.
