Adipose‐derived mesenchymal stem cell injection into the KI10 acupoint mitigates cartilage damage in KOA rats through PGE2‐mediated α7nAChR/NF‐κB pathway

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In our research, KOA rat models were established and treated with ADSC injection into the KI10 acupoint. Pain relief, behavioral function, and joint structural improvements were systematically assessed using ethological tests, imaging, histopathological staining, transmission electron microscopy, and molecular analyses.

Loperamide Inhibits Tachykinin NK3-Receptor-Triggered Serotonin Release Without Affecting NK2-Receptor-Triggered Serotonin Release From Guinea Pig Colonic Mucosa

open access: yesJournal of Pharmacological Sciences, 2005
The effect of loperamide on tachykinin NK2- and NK3-receptor-mediated 5-HT outflow from guinea pig colonic mucosa was investigated in vitro. The selective tachykinin NK2-receptor agonist [β-Ala8]-neurokinin A4–10 (βAla-NKA) or the selective NK3-receptor ...

Current evidence for a modulation of low back pain by human genetic variants [PDF]

open access: yes, 2009
The manifestation of chronic back pain depends on structural, psychosocial, occupational and genetic influences. Heritability estimates for back pain range from 30% to 45%. Genetic influences are caused by genes affecting intervertebral disc degeneration

Neurotransmitter‐Defined Degeneration Patterns in Sporadic and C9orf72‐Associated Amyotrophic Lateral Sclerosis: Predilection to GABAergic, Serotonergic, Opioid, Glutamatergic, Endocannabinoid, and Microglial Systems—Implications for Therapy Development

open access: yesAnnals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a markedly distinctive clinical and neuroradiological signature, with the preferential involvement of specific brain networks and the apparent sparing of others. The molecular underpinnings of the strikingly selective anatomical vulnerability have not been fully elucidated to date despite the potential ...

Social trauma and the mu-opioid system in depression [PDF]

open access: yes, 2011
The overarching thesis under investigation is that the endogenous opioid system plays a key role in depression subsequent to traumatic childhood social experiences. This is suggested by the fact that animal work indicates that mu-opioids robustly mediate

Bidirectional Regulation of Opioid and Chemokine Function

open access: yesFrontiers in Immunology, 2020
The opioid family of GPCRs consists of the classical opioid receptors, designated μ-, κ-, and δ-opioid receptors, and the orphanin-FQ receptor, and these proteins are expressed on both neuronal and hematopoietic cells.

The Role of Opioids on Motor Activity in Physio-pathological Conditions [PDF]

open access: yes, 2009
To date, four principal classes of opioid peptide receptors, μ (MOP), κ (KOP), δ (DOP) and ORL- 1 (NOP) have been identified and cloned. The experimental and clinical importance of this receptor family has been amply demonstrated in many diseases ...

Therapeutic Prospects of Ketamine for Cataplexy in Narcolepsy Type 1: Evidence from a Human Case and a Murine Model

open access: yesAnnals of Neurology, EarlyView.
Narcolepsy type 1 is characterized by cataplexy, for which current treatments targeting monoaminergic, histaminergic, and GABAergic pathways may be ineffective or poorly tolerated. We report the case of a 34‐year‐old man with narcolepsy type 1, intolerant to standard therapies, who experienced marked and sustained cataplexy reduction with morning ...

Kappa Opioid Regulation of Stress-Related Behavior [PDF]

open access: yes, 2010
Anxiety disorders affect roughly 40 million American adults in a given year. Those suffering from anxiety disorders often experience additional stress-linked illnesses, such as depression.

Biochemical pharmacology of the positive allosteric modulation of the GABAb receptor "in Vitro" and "in Vivo" [PDF]

open access: yes, 2007
Allosteric modulators of G-protein coupled receptors (GPCRs) interact with binding sites on the receptor molecule that are topographically distinct from the classic orthosteric site.
