Abstract
β-caryophyllene (BCP) is a cannabinoid receptor CB2 agonist plant-derived terpenoid found in different essential oil plants, including rosemary, black pepper, copaiba and cannabis. It has GRAS (generally recognized as safe) status and is approved by the FDA (Food and Drug Administration) for food use. BCP displays agonist activity on the CB2 receptor and is a potential therapeutic target in several neuropsychiatric disorders, including anxiety and drug addiction. Unlike CB1 receptors, activation of the CB2 receptors is devoid of psychotomimetic and addictive properties. In this regard, this study aimed to evaluate the effects of BCP on incentive salience ("wanting") performance and motivational properties elicited by sweetened palatable foods in female Swiss mice. After 9 days of training for incentive salience performance for a sweet reward (hazelnut cream with chocolate), food-restricted mice received a systemic injection of BCP (50 and 100 mg/kg) before testing over 3 days. Moreover, independent groups of female mice were tested on sweet reward-induced conditioned place preference (CPP) for 22 consecutive days. To evaluate BCP effects on the expression of seeking behaviour for sweetened food, mice received a single intraperitoneal injection of BCP (50 mg/kg) 30 min before testing on the CPP task. BCP significantly decreased the incentive performance for a sweet reward compared with the control group in a CB2 receptor-dependent manner. Also, BCP suppressed the expression of sweet reward-CPP. Altogether, these preclinical data demonstrate the potential role of BCP in treating disorders associated with food addiction-like behaviour.

Abstract
Fibromyalgia (FM) is an idiopathic disorder characterized by generalized pain and associated symptoms such as depression and anxiety. Cannabis sativa shows different pharmacological activities, such as analgesic, anti-inflammatory, neuroprotective, and immunomodulatory. Associated with this, the use of an oil with low concentrations of THC can reduce the psychomimetic adverse effects of the plant. Therefore, the present study aimed to evaluate the analgesic effect of broad-spectrum cannabis oil with low THC concentration in an experimental model of FM. Mechanical hyperalgesia, thermal allodynia, depressive- and anxious-related behavior, and locomotor activity were evaluated after reserpine (0.25 mg/kg; injected subcutaneously (s.c.) once daily for three consecutive days) administration. Our results showed that oral administration of broad-spectrum cannabis oil (0.1, 1, and 3 mg/kg, p.o.) in a single dose on the 4th day inhibited mechanical hyperalgesia and thermal allodynia induced by reserpine. Relevantly, treatment during four days with broad-spectrum cannabis oil (0.1 mg/kg, p.o.) reduced mechanical hyperalgesia 1 h after reserpine administration. Intraplantar treatment with cannabis oil significantly reversed mechanical and heat thermal nociception induced by reserpine injection. Interestingly, spinal and supraspinal administration of broad-spectrum cannabis oil completely inhibited mechanical hyperalgesia and thermal sensitivity induced by reserpine. The repeated cannabis oil administration, given daily for 14 days, markedly mitigated the mechanical and thermal sensitivity during the FM model, and its reduced depressive-like behavior induced by reserpine. In summary, broad-spectrum cannabis oil is an effective alternative to reverse the reserpine-induced fibromyalgia model.

Abstract
The understanding of the biological mechanisms involved in root resorption in deciduous teeth is important to the future development of preventive measures and treatments of this condition. The aim of the present study was to compare the expression and immunostaining of iNOS, MMP-9, OPG and RANKL in the periodontal ligament (PDL) of deciduous teeth with physiologic root resorption (GI), inflammatory pathological root resorption (GII) and permanent teeth (GIII), the negative control. Teeth in GI (n = 10), GII (n = 10) and (GIII) (n = 10) were submitted to immunohistochemical analysis to determine the expression of iNOS, MMP-9, OPG, and RANKL. The immunostaining was analysed by optical density. Statistical analysis included one-way ANOVA, followed by Student-Newman-Keuls post hoc test (p < 0.05). The results showed that iNOS, MMP-9 and RANKL expression in the PDL was higher in GII compared to GI and GIII (p < 0.05). Moreover, RANKL expression was higher in GI compared to GIII (p < 0.001), while OPG immunolabelling was lower in GII compared to GI and GIII (p < 0.001). The PDL of deciduous teeth bearing inflammatory processed exhibited upregulation of resorption-associated factors as well as enzymes related to tissue degradation which, in turn explains the exacerbation and greater susceptibility of those teeth to root resorption process.

Abstract
Fibromyalgia (FM) is a complex pathology described as persistent hyperalgesia including somatic and mood dysfunctions, depression and anxiety. Although the etiology of FM is still unknown, a significant decrease in biogenic amines is a common characteristic in its pathogenesis. Here, our main objective was to investigate the role of dopamine D3/D2 receptor during the reserpine-induced pain in mice. Our results showed that pramipexole (PPX) - a dopaminergic D3/D2 receptor agonist - inhibited mechanical allodynia and thermal sensitivity induced by reserpine. Relevantly, PPX treatment decreased immobility time and increased the number of grooming in the forced swimming test and splash test, respectively. Animals that received PPX remained longer in the open arms than the reserpine group using elevated plus-maze apparatus. The repeated PPX administration, given daily for 4 days, significantly blocked the mechanical and thermal allodynia during FM model, similarly to pregabalin, although it failed to affect the reserpine-induced thermal nociception. Reserpine administration induced significant downregulation of dopamine concentration in the central nervous system, and repeated treatment with PPX restored dopamine levels in the frontal cortex and spinal cord tissues. Moreover, PPX treatment inhibited oxidants production such as DCFH (2',7'-dichlorodihydrofluorescein) and nitrite, also decreased oxidative damage (carbonyl), and upregulated the activity of superoxide dismutase in the spinal cord. Together, our findings demonstrated the ability of dopamine D3/D2 receptor-preferring agonist in reducing pain and mood dysfunction allied to FM in mice. All experimental protocols were approved by the Universidade Federal de Santa Catarina (UFSC) Ethics Committee (approval No. 2572210218) on May 10, 2018.

Abstract
The main objective of this study was to investigate the effects of bacterial cellulose hydrogel (BCH) incorporated into montmorillonite (MMT) and its underlying mechanisms of action on a skin wound healing mouse model following pressure injury model. Komagataeibacter hansenii was used to obtain 5 cm in diameter and 0.8 mm of thickness circular bacterial cellulose (BC) sheets, which were incorporated with MMT by deposition ex-site using a 0.1% MMT suspension (100 rpm for 24 h at 28 °C). Afterward, Fourier Transform Infrared Spectroscopy (FT-IR) and Scanning Electron Microscopy (SEM) were used to characterize the bacterial cellulose hydrogel incorporated into montmorillonite (BCH-MMT). The pressure injury model was assessed by macroscopic and histological analysis in male Swiss mice. Both, BC and BCH-MMT, showed a typical FTIR spectrum of cellulosic substrates with pronounces bands around 3344, 2920, 1637, and 1041 cm-1 while microparticles of MMT dispersed uniformly throughout BC were revealed by SEM photographs. Animals treated with BCH-MMT showed significant healing of pressure ulcers as demonstrated by reduced area of redness and spontaneous hyperalgesia, lower amounts of in-site inflammatory cells (to the same level as the positive control Dersani®) and ultimately, complete epidermis re-epithelialization and tissue regeneration. Altogether, these findings suggest that a modified BCH-MMT film could serve as scaffolding for skin tissue engineering and potentially as a novel dressing material for pressure injury.

Abstract
The mammary glands are constituted of different cell types. For example, the epithelial cells appear as the target in many studies since they produce and secrete milk during lactation and are the origin of many human breast cancers. Mammary gland biology is characterized by dynamic tissue growth, function and regression phases, which are understood mainly due to tissue culture studies. Cell culture is probably one of the most used in vitro scientific models, and the most common research model is still the two-dimensional (2D) culture system. Different approaches and conditions have been tested and used to improve the isolation, growth, yield and maintenance of viability of mammary gland cells. Therefore, our study aimed to explore and summarize the cell culture techniques with normal human mammary gland cells cultured in a monolayer. A search strategy was conducted using the electronic databases 'PubMed', 'Scopus' and 'Virtual Health Library'. The search was carried out using the keywords 'cell culture' and 'mammary gland' and 'human'. The main search was carried out by two authors between July and August 2021. In addition, we performed a review matrix elaborated in a spreadsheet to organize and systematize information about each article for inclusion. A total of 11 studies were included in the review and have conducted qualitative analyses on them. Although studies of these cells have been reported since the 1970 s, most found are from the last decade and are largely carried out in the USA. In addition, it was possible to verify the Human Mammary Epithelial Cells (HMEC) primary culture obtained from breast surgery as the main cell type studied. These cells are cultivated in Dulbecco's Modified Eagle Medium (DMEM) and M87A medium with diverse supplements. Finally, there was a diversity in the use of dissociation reagents and a lack of information about cryopreservation. We have observed detailed methodological information about these study models, which would propose further investigations.

Abstract
Rosmarinic acid (RA), an ester of caffeic acid and 3, 4-dihydroxyphenyllactic acid, has anti-inflammatory and neuroprotective activities. Herein, this study investigated in silico the drug-likeness and the potential molecular targets to RA. Moreover, it tested the antidepressant-like potential of RA in the lipopolysaccharide (LPS)-induced depression model. RA (MW = 360.31 g/mol) meets the criteria of both Lipinski's rule of five and the Ghose filter. It also attends to relevant pharmacokinetic parameters. Target prediction analysis identified RA's potential targets and biological activities, including the peroxisome proliferator-activated receptor (PPAR) and the cannabinoid receptors CB1 and CB2 . In vivo, RA's acute, repetitive, and therapeutic administration showed antidepressant-like effect since it significantly reduced the immobility time in the tail suspension test and increased grooming time in the splash test. Further, the pretreatment with antagonists of CB1 , CB2 , and PPAR-γ receptors significantly blocked the antidepressant-like effect of RA. Altogether, our findings suggest that cannabinoid receptors/PPAR-γ signaling pathways are involved with the antidepressant-like effect of RA. Moreover, this molecule meets important physicochemical and pharmacokinetic parameters that favor its bioavailability. RA constitutes a promising, innovative, and safe molecule for the pharmacotherapy of major depressive disorder.

Abstract
Background: Posttraumatic stress disorder (PTSD) is a psychiatric condition that manifests through a broad range of symptoms and shares several phenotypes with anxiety and depression. Refractory PTSD affects 10 – 30% of the patients and highlights the need for alternative pharmacotherapy. The suggested involvement of the endocannabinoid system (ECS) with the emotional processes has enlightened the use of Cannabis sp. Then, this study aimed to evaluate the therapeutic effects of a broad-spectrum Cannabis oil on anxiety- and depressive-like behaviors triggered by stressors from combined nature. In addition, this study investigated the effect of the oil on central cannabinoid receptor 1 and serum levels of cytokines, chemokines, and growth factors. Methods: Mice were randomized into five groups (vehicle; Cannabis oil; fluoxetine; single oral dose) and submitted to acute restraint and chronic unpredictable stress. Then, they were behaviorally assessed in the elevated plus-maze test (EPMT), forced swimming test (FST), splash test (ST), and open field test (OFT). The tetrad cannabinoid assay evaluated the central effect of the oil. Serum biomarkers levels were measured by a multiplex bead-based assay. Results: Cannabis oil (0.1 mg/kg, p.o.) significantly reduced the anxiety-like behavior in EPMT in the acute restraint stress model (p < 0.05) as compared to vehicle. Moreover, compared to the vehicle, Cannabis oil significantly reverted the despair and anhedonic-like behaviors in FST (p < 0.05) and ST (p < 0.05), respectively, in chronically stressed mice. Yet, compared to vehicle, therapy with Cannabis oil did not induce cannabinoid-tetrad (p < 0.0001); downregulated granulocyte-macrophage colony-stimulating factor (GM-CSF; p < 0.01) and advanced glycation end-products (RAGE; p < 0.0001); and upregulated vascular endothelial growth factor (VEGF; p < 0.01) serum levels. Conclusion: Altogether, our data suggest the potential of the broad-spectrum Cannabis oil to improve symptoms related to anxiety and depression caused by traumatic events.

Abstract
Fibromyalgia (FM) is characterized by chronic pain and associated comorbidities such as fatigue, anxiety, depression, and sleep disorders. There is a large amount of evidence regarding the benefits of physical exercise in controlling chronic pain. However, there is no consensus on which exercise modality is most suitable and the real benefits of this intervention to treat FM symptoms. The present study investigated the analgesic and antidepressant effects and morphophysiological responses induced by different physical exercise (aerobic and strength protocols) during the experimental model of FM. Spontaneous pain, mechanical hyperalgesia, thermal allodynia, depression-related behavior, and locomotor activity were evaluated weekly, as well as the morphological evaluation of the spinal cord and dorsal root ganglion. Aerobic and strength training protocols consistently abolished nociceptive behaviors, reducing spontaneous pain scores, cold allodynia, and frequency of response to mechanical hyperalgesia. The strength exercise modulated the depressive-like behavior. Finally, our data demonstrated that physical exercise performed for two weeks increased the number of glial cells in the dorsal root horn. However, it was not sufficient to control the other deleterious effects of the reserpine model on the spinal cord and the dorsal root. Together, these results demonstrated that different physical exercise modalities, when performed regularly in mice, proved to be effective and safe non-pharmacological alternatives for the treatment of FM. However, some gaps have yet to be studied regarding the neuroadaptive effects of physical exercise.

Abstract
Jaboticaba, Plinia cauliflora (Mart.) Kausel, is a Brazilian berry traditionally used in folk medicine as treatment for some health conditions. Phenolic compounds such as flavonoids and anthocyanins have previously been detected in the fruit. This current study aimed to evaluate the toxicological effects of jaboticaba peel extract (JPE) on Artemia salina, L929, and MDA-MB-231 cell lines. Besides, JPE antioxidant, acetylcholinesterase, and antifungal activities, and elemental analysis CHNS were also tested. JPE had moderate toxicity (LD50 = 360.92 μg mL-1) on A. salina, non-toxic effect on L929 cell line, and decreased the viability of cancer cell line MDA at 1,000 µg mL-1 and 500 µg mL-1 concentrations. The antioxidant activity toward 2,2-diphenyl-1-picrylhydrazyl (DPPH) performed IC50 = 37.45 ± 0.17 µg mL-1, whereas 45.7% of acetylcholinesterase activity was inhibited. By its elemental composition, JPE is an alternative food supplement and dermocosmetic component. Antifungal potential toward Candida strains was not observed.

Abstract
(−)-β-caryophyllene (BCP), a cannabinoid receptor type 2 (CB2)-selective phytocannabinoid, has already been shown in precedent literature to exhibit both anti-inflammatory and analgesic effects in mouse models of inflammatory and neuropathic pain. Herein, we endeavored to investigate the therapeutic potential of BCP on experimental autoimmune encephalomyelitis (EAE), a murine model of multiple sclerosis (MS). Furthermore, we sought to demonstrate some of the mechanisms that underlie the modulation BCP exerts on autoimmune activated T cells, the pro-inflammatory scenery of the central nervous system (CNS), and demyelination. Our findings demonstrate that BCP significantly ameliorates both the clinical and pathological parameters of EAE. In addition, data hereby presented indicates that mechanisms underlying BCP immunomodulatory effect seems to be linked to its ability to inhibit microglial cells, CD4+ and CD8+ T lymphocytes, as well as protein expression of pro-inflammatory cytokines. Furthermore, it diminished axonal demyelination and modulated Th1/Treg immune balance through the activation of CB2 receptor. Altogether, our study represents significant implications for clinical research and strongly supports the effectiveness of BCP as a novel molecule to target in the development of effective therapeutic agents for MS.

Abstract
Background Previous study showed that extracts from Croton macrostachyus (Euphorbiaceae) exhibit analgesic effects in acute pain models. The present study evaluates the antinociceptive properties of the methanol/methylene chloride extract (MECM) of the stem bark of this plant using mice models of persistent inflammatory and neuropathic pain, and assesses its mechanism of action. Methods MECM was tested on Complete Freund adjuvant (CFA)-induced persistent thermal and mechanical pain, neuropathic pain induced by partial sciatic nerve ligation (PSNL), prostaglandin E2 (PGE2)-induced acute mechanical hyperalgesia, as well as on nociception induced by capsaicin in mice. Mechanical hyperalgesia was assessed using von Frey hair in awake mice. The mechanism of action of MECM was evaluated by using glibenclamide on PGE2-induced hyperalgesia or rimonabant on capsaicin-induced pain. Results MECM administered orally at the doses of 250 and 500 mg/kg, induced long lasting and significant antihyperalgesic effects on CFA-inflammatory and PSNL-induced neuropathic pain. MECM significantly reduced the mechanical hyperalgesia induced by PGE2 either when administered preventively or therapeutically. MECM also significantly and time dependently inhibited the capsaicin-induced nociception. These effects were not affected by glibenclamide or by rimonabant. Conclusions The present results demonstrate that the oral administration of MECM to mice resulted in long lasting antihyperalgesic activity in inflammatory and neuropathic pain as well as in acute and persistent pain. The mechanism underlying the long lasting MECM antihyperalgesic effect is currently unknown, but might be mediated, at least partially, through the modulation of TRPV1 receptors.

Abstract
A fibrose cística (FC), denominada também de mucoviscidose, é uma doença genética do tipo autossômica recessiva que acomete principalmente crianças e indivíduos de raça branca. O objetivo deste estudo foi propiciar uma visão sobre a FC, assim como as possíveis formas de tratamento fisioterapêutico. A pesquisa da literatura foi realizada nas bases de dados SciELO e PubMed, no período de abril de 2002 a março de 2013, através da seleção de artigos científicos referentes à FC, utilizando como palavras-chave: “fibrose cística”, “fisioterapia em fibrose cística” e “fisioterapia respiratória”. Por meio desta revisão, pôde-se observar que, apesar da complexidade da doença, a prática fisioterapêutica, com o uso das técnicas: tapotagem, vibração, drenagem postural (DP), huffing, oscilação oral de alta frequência (OOAF), drenagem autógena (DA) e o ciclo ativo da respiração (CAR), apresenta eficácia tanto no tratamento como na manutenção da qualidade de vida dos pacientes com FC.

Abstract
SCOPE We investigated the protective effect of the flavonoid myricitrin in dextran sulfate sodium (DSS) induced colitis as promising candidate for the treatment of ulcerative colitis which is considered an important worldwide public health problem. METHODS AND RESULTS Male CD1 mice were provided with a solution of filtered water containing 3% w/v DSS ad libitum over a 5-day period followed by 2 days with normal drinking water. Myricitrin was administered orally, once a day, at the doses 1, 3, and 10 mg/kg of body weight. At the end of day 7th, the animals were euthanized and the colonic tissue was collected to be analyzed by RT-PCR, immunohistochemistry and Western blot. Our results showed that oral treatment with myricitrin exerts consistent anti-inflammatory action in DSS-induced acute colitis in mice by the inhibition of the Akt/phosphatidylinositol-3 kinase-dependent phosphorylation. Consequently, the phosphorylation of mitogen-activated protein kinases (MAPK) p38, extracellular signal-regulated protein kinase (ERK1/2), and c-Jun N-terminal kinase and of the nuclear factor B (NF-κB) was reduced and prevented an increase in the cytokines/chemokines levels. CONCLUSION Together, these data reveal that the anti-inflammatory effect of myricitrin in DSS-induced colitis in mice is likely associated with its ability to prevent the activation of upstream kinases, such as phosphatidylinositol-3 kinase-dependent Akt, NF-κB, and mitogen-activated protein kinase.

Abstract
BACKGROUND AND PURPOSE Kinins are pro-inflammatory peptides that are released during tissue injury, including that caused by inflammatory bowel disease. Herein, we assessed the role and underlying mechanisms through which the absence of kinin B(1) receptors exacerbates the development of dextran sulfate sodium (DSS)-induced colitis in mice. EXPERIMENTAL APPROACH B(1) and B(2) receptor antagonists and B(1) receptor knockout mice (B1(-/-) ) were used to assess the involvement of B(1) and B(2) receptor signalling in a DSS-colitis. B(1) receptor, B(2) receptor, occludin and claudin-4 expression, cytokine levels and cell permeability were evaluated in colon from wild-type (WT) and B1(-/-) mice. KEY RESULTS DSS-induced colitis was significantly exacerbated in B1(-/-) compared with WT mice. IL-1β, IFN-γ, keratinocyte-derived chemokine and macrophage inflammatory protein-2 were markedly increased in the colon from DSS-treated B1(-/-) compared with DSS-treated WT mice. Treatment of WT mice with a selective B(1) receptor antagonist, DALBK or SSR240612, had no effect on DSS-induced colitis. Of note, B(2) receptor mRNA expression was significantly up-regulated in colonic tissue from the B1(-/-) mice after DSS administration. Moreover, treatment with a selective B(2) receptor antagonist prevented the exacerbation of colitis in B1(-/-) mice following DSS administration. The water- or DSS-treated B1(-/-) mice showed a decrease in occludin gene expression, which was partially prevented by the B(2) receptor antagonist. CONCLUSIONS AND IMPLICATIONS A loss of B(1) receptors markedly exacerbates the severity of DSS-induced colitis in mice. The increased susceptibility of B1(-/-) may be associated with compensatory overexpression of B(2) receptors, which, in turn, modulates tight junction expression.

Abstract
Inflammatory bowel disease (IBD) affects millions of people worldwide but its pathophysiology remains unclear. Therefore, experimental models of colitis have contributed crucially for the understanding of IBD, and also in the investigations for effective therapies. Herein we investigated the kinetics of inflammatory mediator production and cell infiltration during acute and chronic dextran sodium sulfate (DSS)-induced colitis. The induction phases with DSS were characterized by severe disease activity with massive colonic polymorphonuclear infiltration and increased levels of tumor necrosis factor-α (TNF-α), keratinocyte-derived chemokine (CXCL1/KC), interleukin (IL)-17 and vascular adhesion molecule-1 (VCAM-1). Interestingly, in the recovery periods, we found marked increase of anti-inflammatory mediators IL-10, IL-4, transforming growth factor-β (TGF-β) and cyclooxygenase 2 (COX-2) that seems be essential for the resolution of intestinal inflammation. Furthermore, nuclear factor κB (NFκB) and regulatory T cell marker forkhead box P3 (FoxP3) were increased gradually during experimental colitis, demonstrating a discrepant profile response and evident immune disbalance in the chronic phase of intestinal mucosal inflammation. Taken together, these results provide valuable information for studies on DSS-induced colitis and especially for the identification of biomarkers that predict disease course and possible therapeutic interventions.

Abstract
Persistent pains associated with inflammatory and neuropathic states are prevalent and debilitating diseases, which still remain without a safe and adequate treatment. Euphol, an alcohol tetracyclic triterpene, has a wide range of pharmacological properties and is considered to have anti-inflammatory action. Here, we assessed the effects and the underlying mechanisms of action of euphol in preventing inflammatory and neuropathic pain. Oral treatment with euphol (30 and 100 mg/kg) reduced carrageenan-induced mechanical hyperalgesia. Likewise, euphol given through the spinal and intracerebroventricular routes prevented mechanical hyperalgesia induced by carrageenan. Euphol consistently blocked the mechanical hyperalgesia induced by complete Freund's adjuvant, keratinocyte-derived chemokine, interleukin-1β, interleukin-6 and tumor necrosis factor-alpha associated with the suppression of myeloperoxidase activity in the mouse paw. Oral treatment with euphol was also effective in preventing the mechanical nociceptive response induced by ligation of the sciatic nerve and also significantly reduced the levels and mRNA of cytokines/chemokines in both paw and spinal cord tissues following i.pl. injection of complete Freund's adjuvant. In addition, the pre-treatment with either CB₁R or CB₂R antagonists, as well as the knockdown gene of the CB₁R and CB₂R, significantly reversed the antinociceptive effect of euphol. Interestingly, even in higher doses, euphol did not cause any relevant action in the central nervous system. Considering that few drugs are currently available for the treatment of chronic pain states, the present results provided evidence that euphol constitutes a promising molecule for the management of inflammatory and neuropathic pain states.

Abstract
BACKGROUND AND PURPOSE Phosphoinositide 3-kinase-γ (PI3Kγ) is implicated in many pathophysiological conditions, and recent evidence has suggested its involvement in colitis. In the present study, we investigated the effects of AS605240, a relatively selective PI3Kγ inhibitor, in experimental colitis and its underlying mechanisms. EXPERIMENTAL APPROACH Acute colitis was induced in mice by treatment with trinitrobenzene sulphonic acid (TNBS), and the effect of AS605240 on colonic injury was assessed. Pro-inflammatory mediators and cytokines were measured by immunohistochemistry, elisa, real time-polymerase chain reaction and flow cytometry. KEY RESULTS Oral administration of AS605240 significantly attenuated TNBS-induced acute colitis and diminished the expression of matrix metalloproteinase-9 and vascular endothelial growth factor. The colonic levels and expression of IL-1β, CXCL-1/KC, MIP-2 and TNF-α were also reduced following therapeutic treatment with AS605240. Moreover, AS605240 reduced MIP-2 levels in a culture of neutrophils stimulated with lipopolysaccharide. The mechanisms underlying these actions of AS605240 are related to nuclear factor-κ (NF-κB) inhibition. Importantly, the PI3Kγ inhibitor also up-regulated IL-10, CD25 and FoxP3 expression. In addition, a significant increase in CD25 and FoxP3 expression was found in isolated lamina propria CD4+ T cells of AS605240-treated mice. The effect of AS605240 on Treg induction was further confirmed by showing that concomitant in vivo blockade of IL-10R significantly attenuated its therapeutic activity. CONCLUSIONS AND IMPLICATIONS These results suggest that AS605240 protects mice against TNBS-induced colitis by inhibiting multiple inflammatory components through the NF-κB pathway while simultaneously inducing an increase in the functional activity of CD4+CD25+ Treg. Thus, AS605240 may offer a promising new therapeutic strategy for the treatment of inflammatory bowel diseases.

Abstract
BACKGROUND AND PURPOSE Resolution of inflammation is mediated by endogenous molecules with anti-inflammatory and pro-resolving activities and they have generated new possibilities for the treatment of inflammatory diseases. Here, we have investigated the possible anti-hyperalgesic effects of two lipids, aspirin-triggered resolvin D1 (AT-RvD1) and its precursor, 17(R)-hydroxy-4Z,7Z,10Z,13Z,15E,17R,19Z-docosahexaenoic acid (17(R)HDoHE). EXPERIMENTAL APPROACH The anti-hyperalgesic effects of both lipid mediators were evaluated, using mechanical and thermal stimuli, at different time-points in adjuvant-induced arthritis in rats. Cytokine levels were measured, and immunohistochemistry and real-time PCR for pro-inflammatory mediators were also performed. KEY RESULTS The precursor of resolvin D series, 17(R)HDoHE, given systemically, inhibited the development and the maintenance of mechanical hyperalgesia in acute inflammation. Such effects were likely to be associated with modulation of both NF-κB and COX-2 in dorsal root ganglia and spinal cord. 17(R)HDoHE was also effective against sub-chronic pain. Unexpectedly, repeated treatment with 17(R)HDoHE did not modify paw and joint oedema in the sub-chronic model, while joint stiffness was prevented. Notably, AT-RvD1 exhibited marked anti-hyperalgesic effects in acute inflammation when given systemically. The efficacy of long-term treatment with either 17(R)HDoHE or AT-RvD1 was partly related to decreased production of TNF-α and IL-1β in rat hind paw. CONCLUSIONS AND IMPLICATIONS Our findings provide fresh evidence for the anti-hyperalgesic properties of 17(R)HDoHE and its pro-resolution metabolite AT-RvD1. Such lipid mediators might be useful for treating pain associated with acute or chronic inflammation. LINKED ARTICLE This article is commented on by Xu and Ji, pp. 274-277 of this issue.

Abstract
Cannabinoid receptor 2 (CB2) activation is suggested to trigger the peroxisome proliferator-activated receptor-γ (PPARγ) pathway, and agonists of both receptors improve colitis. Recently, the plant metabolite (E)-β-caryophyllene (BCP) was shown to bind to and activate CB2. In this study, we examined the anti-inflammatory effect of BCP in dextran sulfate sodium (DSS)-induced colitis and analyzed whether this effect was mediated by CB2 and PPARγ. Oral treatment with BCP reduced disease activity, colonic macro- and microscopic damage, myeloperoxidase and N-acetylglucosaminidase activities, and levels and mRNA expression of colonic tumor necrosis factor-α, IL-1β, interferon-γ, and keratinocyte-derived chemokine. BCP treatment also inhibited the activation of extracellular signal-regulated kinase 1/2, nuclear factor κB, IκB-kinase α/β, cAMP response element binding and the expression of caspase-3 and Ki-67. Moreover, BCP enhanced IL-4 levels and forkhead box P3 mRNA expression in the mouse colon and reduced cytokine levels (tumor necrosis factor-α, keratinocyte-derived chemokine, and macrophage-inflammatory protein-2) in a culture of macrophages stimulated with lipopolysaccharide. The use of the CB2 antagonist AM630 or the PPARγ antagonist GW9662 significantly reversed the protective effect of BCP. Confirming our results, AM630 reversed the beneficial effect of BCP on pro-inflammatory cytokine expression in IEC-6 cells. These results demonstrate that the anti-inflammatory effect of BCP involves CB2 and the PPARγ pathway and suggest BCP as a possible therapy for the treatment of inflammatory bowel disease.
