The pentraxin family plays an important role in the acute phase response to immune-inflammatory processes. The short pentraxin, C-reactive protein (CRP) is a marker of chronic spontaneous urticaria (CSU) activity, reflecting the systemic effects of inflammatory mediators associated with the disease. It is known, that the long pentraxin, pentraxin 3 (PTX3) is produced at the sites of inflammation,...
To study, in normal cartilage explants (CEs) challenged with lipopolysaccharide (LPS), the temporal effects (at 48 and 96h) of leukocyte- and platelet-rich gel (L-PRG) and pure platelet-rich gel (P-PRG) supernatants on the production and degradation of platelet-associated growth factors (GFs) (platelet-derived GF isoform BB [PDGF-BB] and transforming growth factor beta-1 [TGF-β1]), pro-inflammatory...
At early stages, the growth of prostate cancers is androgen dependent. At later stages, however, the growth of prostate cancers becomes androgen independent, which leads to an increase in mortality. The switch to an androgen-refractory state is associated with neuroendocrine differentiation (NED) of prostate cancer cells. Several factors including interleukin-6 (IL-6) and increased cAMP production...
Posttranslational protein modification by ISG15 plays an important role in antiviral defense. We selectively inactivated the ISG15 isopeptidase activity of USP18 in mice. Increased ISGylation was accompanied by enhanced viral resistance without causing detrimental side effects suggesting that USP18 protease inhibition might be a suitable antiviral strategy.
The overall immunopathology of the T-helper cell (Th)-17 immune response has been implicated in various inflammatory diseases including pulmonary inflammation; however its potential role in acute respiratory distress syndrome (ARDS) is not defined. This study aimed to evaluate the Th-17 response in bronchoalveolar lavage fluid (BALF) and blood and from trauma patients with pulmonary complications...
Melanocytes are melanin-producing cells and with emerging innate immune functions including the expression of antiviral interferon-type I cytokines. We herein ascertained the susceptibility of the human melanocytes to Ross River alphavirus (RRV) infection and analyzed the subsequent immune responses. We demonstrated for the first time that (1) SKMEL-28 melanocyte cell line was susceptible to RRV infection...
To examine the platelet recovering and anti-inflammatory effects of IL-11 in the treatment of sepsis, accompanied with thrombocytopenia and to investigate the associated mechanisms via a case-control study.105 patients enrolled for the study were segregated into (1) IL-11 therapy group and (2) conventional therapy group. The IL-11 therapy group was given additional recombinant human IL-11 treatment...
Oxyresveratrol is known to possess anti-inflammatory property. Current study investigates the immunosuppressive effect of oxyresveratrol by using mouse model of ovalbumin (OVA)-induced allergic airway inflammation.BALB/c mice were randomly divided into five groups having 8 mice in each group. Treatment with low dose (7mg/kg) and high dose (15mg/kg) of oxyresveratrol, and methylprednisolone (15mg/kg;...
Porphyromonas gingivalis is a periodontitis-associated pathogen and interactions between the bacterium and gingival fibroblasts play an important role in development and progression of periodontitis, an inflammatory disease leading to degeneration of tooth-supporting structures. Gingival fibroblasts, which expresses protease activated receptors (PARs) as well as toll-like receptors (TLRs), produces...
Resistin is involved in the inflammatory response, as well as in insulin resistance. In rodents, resistin levels are partially regulated by ovarian hormones. Thus, ovariectomy-induced changes in resistin levels and their response to lipopolysaccharide (LPS)-induced septic stress were evaluated. Ovariectomized (OVX) rats exhibited higher serum resistin concentrations and visceral and subcutaneous white...
Active tuberculosis (TB) patients show impaired NK cell function, and the underlying mechanism remains largely unknown. In this study, we confirmed the decrease in activation, cytokine secretion, and degranulation potential of NK cells in active TB patients. We further investigated whether coinhibitory receptor Tim-3 was involved with impairment of NK cells. Our results revealed that the expression...
Urogenital schistosomiasis caused by Schistosoma haematobium induces a Th2 immune response, including expression of Interleukin-6. IL-6 confers protection from experimental Schistosoma-induced pulmonary hypertension and modulates production of mannose-binding lectin (MBL) and other lectins. We studied IL-6 levels in schistosomiasis and its effect on lectins production. Elevated IL-6 levels occurred...
Interleukin (IL)-35 is a novel regulatory cytokine primarily produced by regulatory T cells. Accumulating evidence has established that IL-35 plays an important role in the regulation of immune homeostasis, but little is known regarding the function of IL-35 in acquired aplastic anemia (AA). The aim of the present study was to investigate the expression of IL-35 and its effects on T cell response...
Natural killer (NK) cells are the key lymphocytes in solid tumors. Its activity is regulated by both germline encoded receptors and cytokine microenvironment. We conducted a case-control study to investigate the activation status of NK cell in oral squamous cell carcinoma (OSCC). NK cell activation was assessed in context of NK cell cytotoxicity and transcript expression of NK cell receptors (NKp46...
Polyphenolic compound tannic acid, which is mainly found in grapes and green tea, is a potent antioxidant with anticarcinogenic activities. In this present study, we hypothesized that tannic acid could inhibit nuclear factor (NF)κB signaling and inflammation in atopic dermatitis (AD) NC/Nga mice. We have analyzed the effects of tannic acid on dermatitis severity, histopathology and expression of inflammatory...
ST segment elevation myocardial infarction (STEMI) is one of the leading causes of morbidity and mortality and some characteristics of STEMI are poorly understood. The aim of the present study is to detect protein expression profiles in the serum of STEMI patients, and to identify biomarkers for this disease. Cytokine profiles of serum from STEMI patients and healthy controls were analyzed with a...
Cervical cancer (CeCa) tumors are characterized by increased expression of TGF-β1 and IL-10, which are correlated with downregulated expression of major histocompatibility complex class I antigens (HLA-I) on cancer cells and a reduced immune response mediated by cytotoxic T lymphocytes (CTLs). Mesenchymal stromal cells (MSCs) are important components in the tumor microenvironment that have been suggested...
Obesity is closely associated with increased production of pro-inflammatory adipokines, including interleukin (IL)-6, plasminogen activator inhibitor (PAI)-1, and adipose-tissue-derived monocyte chemoattractant protein (MCP)-1, which contribute to chronic and low-grade inflammation in adipose tissue. Harpagoside, a major iridoid glycoside present in devil’s claw, has been reported to show anti-inflammatory...
Mycobacterium leprae and Human Immunodeficiency Virus (HIV) are causative agents known to be involved in nerve damage in leprosy and HIV-peripheral neuropathy (HIV-PN) respectively. Among other peripheral neuropathies the most common is diabetic neuropathy, which is metabolically induced. The proinflammatory cytokines TNF-α and IFN-γ have been implicated in the pathogenesis of peripheral neuropathy...
