Repeated lipopolysaccharide exposure is often used in longitudinal preclinical models of depression. However, the potential phenotypic differences from acute depression-mimicking effects are rarely described. This study compared chronic lipopolysaccharide administration of doses previously used in depression research to a new mode of escalating dose injections. Adult male BALB/c mice ( n=8/group) were injected intraperitoneally with either a single 0.83 mg/kg dose, a repeated 0.1 mg/kg lipopolysaccharide dose or a dose which escalated weekly from 0...

BACKGROUND: IL-33 plays critical role in the regulation of tissue homeostasis, injury and repair. Whether IL-33 regulates neutrophil recruitment and function independently of airways hyperresponsiveness (AHR) in ozone induced lung injury and inflammation is unclear. OBJECTIVE: To examine the role of IL-33/ST2 axis in lung inflammation upon acute ozone exposure in mice. METHODS: ST2 and IL-33 deficient mice, IL-33-citrine reporter and C57BL/6 (WT) mice underwent a single ozone exposure (1 ppm for 1h) in all studies...

Interleukin-33 (IL-33) has been identified as a natural ligand of ST2L. IL-33 primarily acts as a key regulator of Th2 responses through binding to ST2L, which is antagonized by soluble ST2 (sST2). The IL-33/ST2L axis is involved in various inflammatory pathologies, including ulcerative colitis (UC). Several recent investigations have also suggested that the IL-33/ST2L axis plays a role in colorectal cancer (CRC) progression. In CRC, tumor- and stroma-derived IL-33 may activate ST2L on various cell types in an autocrine and paracrine manner...

BACKGROUND: Immune and inflammatory responses occurring in the spinal cord play a pivotal role in the progression of radicular pain caused by intervertebral disk herniation. Interleukin-33 (IL-33) orchestrates inflammatory responses in a wide range of inflammatory and autoimmune disorders of the nervous system. Thus, the purpose of this study is to investigate the expression of IL-33 and its receptor ST2 in the dorsal spinal cord and to elucidate whether the inhibition of spinal IL-33 expression significantly attenuates pain-related behaviors in rat models of noncompressive lumbar disc herniation...

Objective: To investigate the effects of Lactobacillus paracasei N1115 combined with fructooligosaccharides (FOS) on non-alcoholic fatty liver disease (NAFLD) in mice and its possible mechanism. Methods: A total of 50 male C57 mice were randomly and equally divided into five experimental groups. Group 1 received a normal diet (ND). Other four groups received a high-fat diet (HFD) to establish NAFLD models. In addition to HFD, group 3 received Lactobacillus paracasei N1115 (2.2×10(9) CFU/mL), group 4 received FOS (4 g/kg per day), and group 5 received Lactobacillus paracasei N1115 (2...

BACKGROUND: The interleukin-33 (IL-33)/supressor of tumorigenicity 2 (ST2) pathway is suggested to play an important role in fibrosis, remodeling and the progression of heart failure (HF). Increased soluble (sST2) levels are associated with adverse outcome in the average HF population. Less is known about sST2 levels in end-stage HF. Therefore, we studied sST2 levels in end-stage HF and the effect of unloading by left ventricular assist device (LVAD) support on sST2 levels. METHOD AND RESULTS: Serial plasma measurements of sST2 were performed pre-implantation and 1, 3 and 6 months after (LVAD) implantation in 38 patients...

Importance: Nearly half of all patients with heart failure have preserved ejection fraction (HFpEF) as opposed to reduced ejection fraction (HFrEF), yet associations of biomarkers with future heart failure subtype are incompletely understood. Objective: To evaluate the associations of 12 cardiovascular biomarkers with incident HFpEF vs HFrEF among adults from the general population. Design, Setting, and Participants: This study included 4 longitudinal community-based cohorts: the Cardiovascular Health Study (1989-1990; 1992-1993 for supplemental African-American cohort), the Framingham Heart Study (1995-1998), the Multi-Ethnic Study of Atherosclerosis (2000-2002), and the Prevention of Renal and Vascular End-stage Disease study (1997-1998)...

INTRODUCTION: Genetic polymorphisms may result in altered gene expression or functional changes of the encoded molecules and could possibly generate a deficient immunity. Consequently, individuals with specific genotypes could be more susceptible to disease or could present an increase in disease severity. Our study is aimed to verify, through a systematic review and meta-analysis registered in the PROSPERO database (CRD42016043905), whether currently available evidence supports a relationship between interleukin gene polymorphisms and apical periodontitis (AP)...

Current treatments for allergic asthma primarily ameliorate symptoms rather than inhibit disease progression. Regulating the excessive T helper type 2 (Th2) responses may prevent asthma exacerbation. In this study, we investigated the protective effects of Ad5-gsgAM, an adenovirus vector carrying two mycobacterial antigens Ag85A and Mtb32, against allergic asthma. Using an ovalbumin (OVA)-induced asthmatic mouse model, we found that Ad5-gsgAM elicited much more Th1-biased CD4+T and CD8+T cells than bacillus Calmette-Guérin (BCG)...

Innate lymphoid cells (ILCs) represent a distinct branch of the lymphoid lineage composed of 3 major subpopulations: ILC1, ILC2, and ILC3. ILCs are mainly described as tissue-resident cells but can be detected at low levels in human blood. However, unlike mouse ILCs, there is still no consistent methodology to purify and culture these cells that enables in-depth analysis of their intrinsic biology. Here, we describe defined culture conditions for ILC2s, which allowed us to dissect the roles of interleukin 2 (IL-2), IL-25, IL-33, and thymic stromal lymphopoietin (TSLP) individually, or in combination, in modulating ILC2 phenotype and function...

Up to 50% of patients with ulcerative colitis (UC) or Crohn's disease (CD) experience a loss of response (LOR) to infliximab after an initial response to the drug. Granulocyte/monocyte apheresis (GMA) with the Adacolumn depletes the activated myeloid leukocytes that are known to exacerbate and perpetuate inflammatory bowel diseases, but GMA has hitherto not been applied to patients with LOR to infliximab. We report three cases (2 UC and 1CD) with LOR to maintenance infliximab therapy that received one GMA session/week for 3 consecutive weeks or more...

The interleukin-33 (IL-33)/suppression of tumorigenicity 2 (ST2) pathway is a potential pathophysiological mediator of cardiac fibrosis. Soluble ST2 (sST2) is one of the main isoforms of ST2 with strong prognostic value in cardiac disease. The exact role of sST2 in cardiac fibrosis is unknown. The aim of this study was (1) to investigate myocardial expression of the IL-33/ST2 pathway in relation to myocardial fibrosis in end-stage heart failure patients and (2) to study whether plasma sST2 is associated with histologically determined cardiac fibrosis...

Context: Primary hypothyroidism has been thought of as an inflammatory condition characterized by raised levels of cytokines such as C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α). Depression is also well known to occur in hypothyroidism. Depression is also characterized by elevated inflammatory cytokines. We planned to study whether cytokines play an important part in linking these two conditions. Objectives: (1) To know the prevalence of depression in overt hypothyroidism due to autoimmune thyroid disease...
