Sirtuin 2 (SIRT2), a member of the mammalian sirtuin family, plays an important role in the pathogenesis of various neurological diseases. However, whether SIRT2 is involved in the regulation of neuropathic pain remains unclear. In this study, we aimed to investigate the potential role of SIRT2 in regulating neuropathic pain in a rat model induced by chronic constriction injury (CCI). We found that SIRT2 was downregulated in the dorsal root ganglion (DRG) in CCI rats. Intrathecal injection of a recombinant adenovirus expressing SIRT2 markedly alleviated mechanical allodynia and thermal hyperalgesia in CCI rats...

L-selectin and P-selectin glycoprotein ligand-1 (PSGL-1) are adhesion molecules which induce similar physiological events. Our previous paper showed that phosphatidylinositol 3-kinase (PI3K) played a crucial role in L-selectin- and PSGL-1-mediated F-actin redistribution and assembly during neutrophil rolling on E-selectin. However, it is not clear whether L-selectin and PSGL-1 induce other similar physiology events by PI3K. Here, we investigated the possibility of PI3K linking the signaling pathways of L-selectin and PSGL-1 to IL-18 transcription...

Decreased interferon (IFN)-γ levels and increased levels of macrophage-derived chemokine (MDC) and intercellular adhesion molecule (ICAM)-1 are known to be involved in allergic skin diseases, such as eczema and atopic dermatitis. Activation of the IFN-γ and its downstream interleukin-12 (IL-12) pathway can correct these diseases. Suppressor of cytokine signaling 1 (SOCS1) is a cytokine signaling inhibitor that blocks downstream pathways of IFN-γ by blocking the mitogen-activated protein kinase (MAPK) and protein kinase B (Akt) signaling pathways...

Osteoarthritis (OA) is a chronic degenerative joint disease that is principally characterized by progressive joint dysfunction and cartilage degradation. Inflammation and apoptosis play critical roles in the progression of OA. Geniposide (GPO), one of the principal components of the fruit of Gardenia jasminoides Ellis, has been reported to have anti-inflammatory and other pharmacological effects. In this study, we performed in vitro experiments on rat chondrocytes to examine the therapeutic effects of GPO on OA and investigated its effects in vivo in a rat model of OA induced by medial meniscal tear (MMT)...

Rosmarinic acid (RA), a type of food additives mainly extracted from rosemary, has been reported to possess anti-inflammatory activities in some previous studies. However, the effects of RA on lipopolysaccharide (LPS)-induced mastitis have not been reported. Here, we investigated the anti-inflammatory effects of RA on LPS-induced mastitis in mice and elucidated the potential mechanisms in mouse mammary epithelial cells (mMECs). RA treatment significantly ameliorated the mammary structural damage, and reduced the activity of myeloperoxidase...

Sepsis is a systemic inflammatory disorder which often occurs during extremely stressful conditions such as trauma, burn, shock, and infection. This study investigated the curative effects of bone marrow-derived mesenchymal stem cells (BM-MSCs) against hepatic, renal, and pulmonary responses caused by a single administration of lipopolysaccharide (LPS) (10 mg/kg, i.p) in rats. Treatment with BM-MSCs (5 × 105 in 0.1 ml PBS, i.p.) 3 h after LPS antagonized the LPS-induced increment of the liver enzymes (ALT, AST) and kidney functions (BUN, sCr)...

Over-activated microglial cells are known to be implicated in various neurological diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), and multiple sclerosis. Our previous reports have shown that ZL006, a compound with a hydrophobic ring A and a hydrophilic ring B with a carboxyl group, exhibited stronger neuroprotective activity in vitro and in vivo. However, the directly anti-inflammatory effects of these compounds in the central nervous system (CNS) have not been elucidated. In the present study, as a part of our ongoing screening experiment to evaluate the anti-inflammatory effects of new compounds, a newly synthesized 4-((5-bromo-3-chloro-2-hydroxybenzyl) amino)-2-hydroxybenzoic acid (LX007) was used to examine whether it could reduce the inflammatory responses of activated microglia...

Salidroside is neuroprotective across a wide therapeutic time-window after cerebral ischemia-reperfusion injury (IRI). Here, we investigated the role of complement in mediating effects of salidroside after cerebral IRI in rats. Rats were administrated with vehicle or salidroside 50 mg/kg, given daily for either 24 or 48 h, after middle cerebral artery occlusion (MCAO) for 2 h and reperfusion for 1 h. Levels of proteins in ischemic brain were measured by immunofluorescence and western blotting. We observed early increases in the deposition of immunoglobulin M, mannose-binding lectin 2, and annexin IV on cerebral endothelial cells, induction of the complement components C3 and C3a, by 24 h after IRI, and a later significant increase in the complement component C1q by 48 h...

Brain dysfunction is a common complication after sepsis and is an independent risk factor for a poor prognosis, which is partly attributed to the dysregulated inflammatory response and oxidative damage. Melatonin regulates the sleep-wake cycle and also has potent anti-inflammatory and antioxidant properties, yet the protective effects of melatonin on sepsis-induced neurobehavioral dysfunction remain to be elucidated. In the present study, melatonin was administered intraperitoneally daily at a dose of 10 mg/kg for three consecutive days immediately (early treatment) or 7 days (delayed treatment) after sham operation or cecal ligation and puncture (CLP), followed by an additional treatment in drinking water until the end of behavioral tests...

The α7 nicotinic acetylcholine receptor (α7-nAChR) is associated with inflammation, re-epithelialization, and angiogenesis in wound healing process. A recent study demonstrated that PNU-282987, a selective agonist of α7-nAChR, accelerates the repair of diabetic excisional wounds. Whether α7-nAChR activation promotes non-diabetic wounds healing is unknown. The aim of this study was to evaluate the effects of α7-nAChR activation on non-diabetic wound healing. The effects were evaluated in two wound models...

Sepsis is a disease that occurs as a result of systemic inflammatory response syndrome (SIRS) in response to an infection, contributing to multiple organ dysfunction and a high mortality rate. Interleukin-lβ (IL-1β) is a cytokine that plays critical roles in inflammation and cardiac dysfunction during severe sepsis. Intermedin1-53 (IMD1-53) has been recently discovered to possess potential endogenous anti-inflammatory and strong cardiovascular protective effects. To investigate whether IMD1-53 can inhibit the NLRP3/caspase-1/IL-1β pathway to alleviate cardiac injury and rescue heart function, sepsis was induced in vivo by caecal ligation and puncture (CLP) surgery, and lipopolysaccharides were used as septic stressors for cardiac fibroblasts (CFs) in vitro...

Psoriasis is an immune-mediated chronic skin disorder where T cells play a main role, and numerous inflammatory cytokines are implicated in its pathogenesis by initiating keratinocyte proliferation. Interleukin-22 (IL-22), an IL-10 family cytokines, is critical in the pathogenesis and development of psoriasis. To determine the target of microRNA (miR) -548a-3p and investigate its role in keratinocyte proliferation after treating human keratinocytes (HaCaT) with IL-22, we used quantitative reverse transcriptase PCR to measure the expression of miR-548a-3p in both HaCaT cells stimulated with IL-22 and psoriatic lesions, and then detected the biological function of miR-548a-3p in HaCaT cells by performing Counting Kit-8 (CCK-8) assays...

Rheumatoid arthritis (RA) is a systemic autoimmune disease that may cause bone damage and worsening disability. Manipulating antigen-specific Treg cells is a promising approach to treat autoimmune disease since the immune suppressive function of Treg cells has the feature of antigen specificity which could avoid overall immune suppression. It has been known that the function of Treg cells is impaired in RA, and adoptive transfer of Treg cells is effective in suppressing RA. Here, we designed a new approach to generate antigen-specific Treg cells by culturing CD4+ T cells from mice with RA onset, and we also proved that the adoptive transfer of these antigen-specific Treg cells reversed the collagen-induced arthritis (CIA) progression by suppressing the key inflammatory cytokine TNF-α...

The AIM2 inflammasome pathway has been determined to play an important role in cellular immune defense against bacterial and viral infections; however, its function and regulatory mechanism in human dental pulp cells (HDPCs) during pulpitis remains poorly understood. In this study, we explored whether the AIM2 inflammasome pathway was activated in HDPCs in response to dsDNA and defined its role in regulating IL-1β secretion. We demonstrated that stimulation with IFN-γ and cytoplasmic DNA significantly activated the AIM2 inflammasome and increased IL-1β secretion in HDPCs...
