Activation of vagus nerve exerts orexin-A (OXA)-mediated suppression of post-ischemic glucose intolerance and cerebral ischemic neuronal damage. Cerebral ischemia induces hepatic inflammatory factors and contributes to the development of hepatic insulin resistance by activating sympathetic nerves. However, it is not enough to understand whether OXA regulates these phenomena through activation of vagus nerve. In this study, we demonstrated that the involvement of OXA-induced activation of vagus nerve in the induction of hepatic inflammatory factors by cerebral ischemia...

Dynorphin 1-17 (DYN 1-17) is biotransformed rapidly to a range of fragments in rodent inflamed tissue with dynorphin 3-14 (DYN 3-14) being the most stable and prevalent. DYN 1-17 has been shown previously to be involved in the regulation of inflammatory response following tissue injury, in which the biotransformation fragments of DYN 1-17 may possess similar features. This study investigated the effects of DYN 3-14 on lipopolysaccharide (LPS)-induced nuclear factor-kappaB/p65 (NF-κB/p65) nuclear translocation and the release of pro-inflammatory cytokines interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) in differentiated THP-1 cells...

The neuropeptide substance P (SP) is an important mediator of neurogenic inflammation within the central and peripheral nervous systems. SP has been shown to induce the expression of pro-inflammatory cytokines implicated in the pathogenesis of several disorders of the human brain via the neurokinin-1 receptor (NK-1R). Ketamine, an intravenous anesthetic agent, functions as a competitive antagonist of the excitatory neurotransmission N-methyl-D‑aspartate (NMDA) receptor, and also antagonizes the NK-1R by interfering with the binding of SP...

CONTEXT: The biology of fatigue and depression in cancer patients is poorly understood. Hypotheses regarding cytokines and growth factors related to sickness behavior and disruption of circadian signaling have been proposed. OBJECTIVES: We prospectively examined proinflammatory cytokines (e.g., sickness behavior model) and epidermal growth factor receptor (EGFR) ligands (e.g., circadian disruption model) in the serum of cancer patients enrolled in a clinical trial testing levocarnitine for fatigue...

BACKGROUND: Leflunomide is a low-molecular-weight compound that is widely used in the treatment of rheumatoid arthritis. Although leflunomide is thought to act through the inhibition of the de novo pyrimidine synthesis, the molecular mechanism of the drug remains largely unknown. We investigated the antiarthritis effects and mechanisms of action of the active metabolite of leflunomide, A77 1726, in interleukin-1 receptor antagonist-knockout (IL-1Ra-KO) mice. METHODS: 14- to 15-week-old male IL-1Ra-KO mice were treated with 10 or 30 mg/kg A77 1726 via intraperitoneal injection three times per week for 6 weeks...

Atopic dermatitis (AD)-like dermatitis can be induced by repeated topical application of an ointment containing Dermatophagoides farinae body (Dfb) extract in NC/Nga mice. This AD-like murine model also exhibits a biphasic increase in the number of scratching behavior after topical application of Dfb ointment. In this study, we investigated the possible mechanisms underlying the scratching behavior in each phase. An increase in the content of mast cell derived mediators such as histamine and 5-hydroxytryptamine in the lesional skin and increased vascular permeability were observed in the early phase after the Dfb ointment application...

Sepsis-associated encephalopathy is a major complication during sepsis, and an effective treatment remains unknown. Although minocycline (MINO) has neuroprotective effects and is an attractive candidate for treating sepsis-associated encephalopathy, the effect of MINO on synaptic plasticity during sepsis is still unclear. In the present study, we investigated the effects of MINO on long-term potentiation (LTP) in the hippocampus in a cecal ligation and puncture (CLP) mouse model. We divided mice into 4 groups; (1) sham + vehicle, (2) sham + MINO (60 mg/kg, i...

The NLRP3 inflammasome is an intracellular multiple-protein complex that controls the maturation and release of interleukin (IL)-1β and IL-18. Endogenous carbon monoxide (CO) is anti-inflammatory. The aim of this study was to assess the effects/mechanisms of CO-releasing molecule-3 (CORM-3)-dependent modulation of the NLRP3 inflammasome in cardiac fibroblasts (CF) and its effect on myocardial function in sepsis. CF were treated with CORM-3 or inactive CORM-3 (iCORM-3) before NLRP3 inflammasome priming with lipopolysaccharides (LPS) or following activation with adenosine triphosphate (ATP)...

Functional proteins are very promising for protein therapeutics; however, effective delivery of therapeutic proteins remains challenging. Herein, we developed novel core/satellite nanoparticles by tethering therapeutic proteins to the core/shell polymeric particle surface through cucurbit[8]uril (CB[8])-mediated host-guest interactions. The effectiveness of the core/satellite nanoparticles as protein carrier was demonstrated through the intra-articular delivery of interleukin-1 receptor antagonist (IL-1Ra)...

Although interleukin-1β (IL-1β) is a prototypical pro-inflammatory cytokine, the specific mechanisms underlying the role of its cognate receptor, the interleukin-1 receptor (IL-1R) in peripheral sensitization remain to be investigated. Since emerging evidence in the literature indicates that IL-1β can modulate membrane-bound receptors, we decided to examine the involvement of P2Y1 receptor (P2Y1R) in IL-1β induced pain and the potential interaction of P2Y1Rs and IL-1Rs in both naïve and carrageenan injected rats...

BACKGROUND: Increasing evidence suggests that levels of pro-inflammatory and anti-inflammatory cytokines are dysfunctional in alcohol dependence. Moreover, some initial findings demonstrate that these adaptations in peripheral inflammation may contribute to motivation for alcohol and problem drinking via possible direct effects or the indirect effects of stress responsivity. Importantly, the role of pro-inflammatory and anti-inflammatory cytokines in the progression from healthy to problem drinking is not well understood...

AIMS: Interleukin-22 (IL-22) has beneficial effects on body weight, insulin resistance and inflammation in different mouse models, but its relevance for the development of type 2 diabetes in humans is unknown. We aimed to identify correlates of serum IL-22 levels and to test the hypothesis that higher IL-22 levels are associated with lower diabetes incidence. METHODS: Cross-sectional associations between serum IL-22, cardiometabolic risk factors and glucose tolerance status were investigated in 1107 persons of the population-based KORA F4 study...

Environmental and occupational exposures to respirable ultrafine fractions of particulate matter (PM) have been implicated in the initiation and exacerbation of lung diseases. However, the precise mechanisms underlying production of cell damage and death attributed to nanoparticles (NP) on human airway epithelium are not fully understood. This study examined the role of neurotrophic pathways in NP-induced airway toxicity. Size and agglomeration of TiO2 nanoparticles (TiO2-NP) and fine (TiO2-FP) particles were measured by dynamic light scattering...

REVIEW
Sven R Quist, Luise Kraas
Pyoderma gangrenosum (PG) is an orphan disease. While research on such disorders is based on only few randomized multicenter as well as retrospective studies, most of the data comes from case series of small patient groups. Apart from topical and intralesional therapeutic options for early stages and mild disease courses, treatment predominantly involves systemic therapeutic agents. Besides systemic corticosteroids and cyclosporine A (CsA), options also include intravenous immunoglobulins (IVIG) and biologics such as the TNFα inhibitors infliximab, adalimumab, and etanercept; the interleukin (IL) 12/23 antibody ustekinumab; the IL-1 receptor antagonist anakinra; and the IL-1β antibody canakinumab...

Heroin administration suppresses the production of inducible nitric oxide (NO), as indicated by changes in splenic inducible nitric oxide synthase (iNOS) and plasma nitrate/nitrite. Since NO is a measure of host defense against infection and disease, this provides evidence that heroin can increase susceptibility to pathogens by directly interacting with the immune system. Previous research in our laboratory has demonstrated that these immunosuppressive effects of heroin can also be conditioned to environmental stimuli by repeatedly pairing heroin administration with a unique environmental context...

Cannabinoid system is a potential target for pain control. Cannabinoid receptor 1 (CB1) activation play a role in the analgesic effect of cannabinoids once it is expressed in primary afferent neurons. This study investigates whether the anti-hyperalgesic effect of CB1 receptor activation involves P2×3 receptor in primary afferent neurons. Mechanical hyperalgesia was evaluated by electronic von Frey test. Cannabinoid effect was evaluated using anandamide or ACEA, a non-selective or a selective CB1 receptor agonists, respectively; AM251, a CB1 receptor antagonist, and antisense ODN for CB1 receptor...
