Klotho is considered to have renal protective effect by prohibiting the activation of the nuclear factor (NF)-κB pathway, while the role of microRNA-199a (miR-199a)/Klotho in lupus nephritis (LN) is still unknown. A single dose of pristane (0.5 ml) was intraperitoneally injected into 8 weeks-old female mice to establish the LN model. MiR-199a mimic or miR-199a inhibitor, Klotho plasmid or Klotho siRNA, and miR-199a inhibitor plus si-Klotho were transfected into lipopolysaccharides (LPS) stimulated human embryonic kidney 293 T (HEK293 T) cells...

Gingivitis is evidenced by inflammation of the free gingiva, and still reversible. If left untreated, it may then progress to periodontitis. In the present study, the therapeutical effect of ketotifen fumarate on gingivitis was explored. Domestic cats with varying degrees of gingivitis naturally were enrolled in this study. Subgroups of animals were treated twice daily for one week with or without ketotifen fumarate (5 mg/kg). Effects of ketotifen fumarate were measured on gingival index, cells accumulation, mediators release, receptor-ligand interaction, oxidative stress, MAPK and NF-κB pathways, epithelial barrier and apoptosis...

Preterm birth (PTB), the leading cause of neonatal morbidity and mortality, urgently requires novel therapeutic agents. Spontaneous PTB, resulting from preterm labor, is commonly caused by intrauterine infection/inflammation. Statins are well-established, cholesterol-lowering drugs that can reduce inflammation and inhibit vascular smooth muscle contraction. We show that simvastatin reduced the incidence of PTB in a validated intrauterine LPS-induced PTB mouse model, decreased uterine proinflammatory mRNA concentrations (IL-6, Cxcl1, and Ccl2), and reduced serum IL-6 concentration...

BACKGROUND: Interleukin 2 (IL-2) is a growth factor for T and natural killer cells, promotes proinflammatory cytokines, and can lead to durable responses in patients with melanoma. Vascular endothelial growth factor (VEGF) promotes angiogenesis and modulates host innate and adaptive immunity. High VEGF levels were found to be associated with nonresponse to IL-2. Ziv-aflibercept may deplete VEGF and thereby enhance antitumor T-cell responses, thus supporting a combination immunotherapeutic strategy with IL-2...

Recently we reported that IL-4 and IL-13 signaling in murine early thymic progenitors (ETPs) expressing the heteroreceptor (HR) comprising IL-4 receptor α (IL-4Rα) and IL-13 receptor α 1 (IL-13Rα1) activate STAT6 and inhibit ETP maturation potential toward T cells. In this study, we asked whether IL-4 and IL-13 signaling through the HR mobilizes other STAT molecules to shape ETP fate decision. The findings indicate that HR+ ETPs undergoing cytokine signaling display increased STAT1, but not STAT3, phosphorylation in addition to STAT6 activation...

Multiple sclerosis (MS) is a progressive neurodegenerative disease associated with increased infection rates, chronic inflammation, and premature death. Optimization of nutritional status via dietary supplementation may improve immune function in people suffering from MS and lead to decreased rates of infection. Fifteen individuals with a diagnosis of relapsing-remitting MS for an average of 12.4 years (SD =7.4; R = 2, 25) were enrolled in a one-year open-label clinical trial. Participants consumed a broad-spectrum dietary supplement regimen containing polysaccharides, phytochemicals, antioxidants, vitamins, and minerals three times per day...

Acute or chronic inhalation of endotoxin may lead to changes of lung function and inflammatory markers in the airways. Adaptation to workplace exposure may be possible. In this study, we investigated the possible difference in inflammatory markers assessed in nasal lavage fluid (NALF) in chronical exposure compared to voluntary subjects exposed acutely to endotoxin. We sought to define the variability of inflammatory markers in NALF and the dose-related changes after moderate exposure in naïve subjects. Endotoxin exposure (4-1039 EU/m3 ) resulted from routine work during one shift in sewage treatment plants...

BACKGROUND: Type 1 diabetes (T1D) results from loss of immune regulation, leading to the development of autoimmunity to pancreatic β cells, involving autoreactive T effector cells (Teffs). Tregs, which prevent autoimmunity, require IL-2 for maintenance of immunosuppressive functions. Using a response-adaptive design, we aimed to determine the optimal regimen of aldesleukin (recombinant human IL-2) to physiologically enhance Tregs while limiting expansion of Teffs. METHODS: DILfrequency is a nonrandomized, open-label, response-adaptive study of participants, aged 18-70 years, with T1D...
