Leonard B Weinstock, Jill B Brook, Trisha L Myers, Brent Goodman
A patient with severe postural orthostatic tachycardia syndrome (POTS) and mast cell activation syndrome (MCAS) received immunotherapy with low-dose naltrexone (LDN) and intravenous immunoglobulin (IVIg) and antibiotic therapy for small intestinal bacterial overgrowth (SIBO). A dramatic and sustained response was documented. The utility of IVIg in autoimmune neuromuscular diseases has been published, but clinical experience with POTS is relatively unknown and has not been reported in MCAS. As a short-acting mu-opioid antagonist, LDN paradoxically increases endorphins which then bind to regulatory T cells which regulate T-lymphocyte and B-lymphocyte production and this reduces cytokine and antibody production...

Kazuo Nakamoto, Shogo Tokuyama
G-protein-coupled receptor 40 (GPR40)/free fatty acid receptor (FFAR) 1 is activated by long-chain fatty acids such as docosahexaenoic acid (DHA). Its receptor is expressed predominantly in the central nervous system (CNS) and in β-cells in the pancreatic Islets. We have already demonstrated that the intracerebroventricular administration of DHA or GW9508, a GPR40/FFAR1 agonist, suppresses formalin-induced pain behavior. It also attenuates complete Freund's adjuvant-induced mechanical allodynia and thermal hyperalgesia, suggesting that these effects occur by increasing β-endorphin release from propiomelanocortin neurons...

We describe a stress-derived type-2 diabetes model in male mice, and formulate new hypotheses on how the model was induced, how diabetes-like alterations were prevented through specific pharmacological treatments, and how its possible neuroendocrine pathogenesis could be hypothesized. Pregnant females arrived in our laboratory on their 14th day of conceptional age. After birth, control mice never showed any apparent behavioral-metabolic-endocrine alterations. However, application of postnatal stress (brief mother deprivation, plus sham injection, daily from birth to weaning), was followed in adult male mice by two series of diabetes-like alterations...

There is a growing body of literature that recognizes the positive effects of exercise on mood states such as anxiety, stress and depression, through physiological and biochemical mechanisms, including endorphins, mitochondria, mammalian target of rapamycin, neurotransmitters and the hypothalamic-pituitary-adrenal axis, and via the thermogenic hypothesis. In addition, psychological mechanisms influence the effects of exercise on mood states, as suggested by both the distraction hypothesis and the self-efficacy hypothesis...

BACKGROUND: A recent clinical trial found that pharmacological blockade of V1b receptors reduces alcohol relapse in alcohol-dependent patients. SSR149415 is a selective V1b receptor antagonist that has potential for development as an alcohol dependency treatment. In this study, we investigated whether SSR149415 alone or in combination with the mu-opioid receptor [MOP-r] antagonist naltrexone (NTN) would alter excessive alcohol drinking in mice. METHODS: Both sexes of C57BL/6J (B6) mice were subjected to a chronic intermittent access (IA) drinking paradigm (two-bottle choice, 24-h access every other day) for 3 weeks...

Puerarin, a major active isoflavone extracted from the root of Pueraria lobate, significantly increases plasma β-endorphin and insulin levels and improves impaired insulin signaling in diabetic animals. However, the target tissues and underlying mechanisms in and through which puerarin functions to ameliorating insulin resistance remains largely unclear. In this study, we showed that puerarin enhanced μ-opioid receptor expression and phosphorylation, and increased insulin-stimulated glucose transporter 4 translocation to the plasma membrane in the skeletal muscle of diabetic rats, which were recaptured by a direct application of puerarin in the palmitate-induced insulin-resistant L6 myotubes...

Meeting humans is an everyday experience for most companion dogs, and their behavior in these situations and its genetic background is of major interest. Previous research in our laboratory reported that in German shepherd dogs the lack of G allele, and in Border collies the lack of A allele, of the oxytocin receptor gene (OXTR) 19208A/G single nucleotide polymorphism (SNP) was linked to increased friendliness, which suggests that although broad traits are affected by genetic variability, the specific links between alleles and behavioral variables might be breed-specific...
