BACKGROUND: IL-33 is one of the most consistently associated gene candidates for asthma identified by GWAS. Studies in mice and in human cells have confirmed the importance of IL-33 in inducing type-2 cytokine production from both group 2 innate lymphoid cells (ILC2) and Th2 cells. However, there are no pharmacologic agents known to inhibit IL-33 release from airway cells. OBJECTIVE: To determine the effect of glucagon like peptide receptor-1 GLP-1R signaling on aeroallergen-induced airway IL-33 production and release and on innate type-2 airway inflammation...

High global prevalence of latent TB infection (LTBI) is a key challenge in distinguishing patients with active pulmonary TB (PTB) from those with LTBI. The functional profile of CD4+ and CD8+ T cell cytokines produced as a response to Mycobacterium tuberculosis antigens vary during the course of tuberculosis (TB) infection. We evaluated antigen-specific CD4+ and CD8+ T cell cytokine response after overnight in vitro stimulation of peripheral blood with mycobacterial antigens ESAT-6, CFP-10, Rv2204c, Rv0753c and Rv0009 by flow cytometry...

The filarial nematode Mansonella perstans is endemic throughout Africa, northern South America and the Caribbean. Interestingly, M. perstans-infected individuals present no distinct clinical picture associated with certain pathology. Due to its relatively silent nature, research on this tropical disease has been neglected, especially M. perstans-driven immune responses. A hindrance in obtaining data on M. perstans-specific responses has been the inability to obtain adult worms since their habitats in serous cavities are difficult to access...

BACKGROUND: Harmful effects of spontaneous breathing have been shown in experimental severe acute respiratory distress syndrome (ARDS). However, in the clinical setting, spontaneous respiration has been indicated only in mild ARDS. To date, no study has compared the effects of spontaneous assisted breathing with those of fully controlled mechanical ventilation at different levels of positive end-expiratory pressure (PEEP) on lung injury in ARDS. OBJECTIVE: To compare the effects of assisted pressure support ventilation (PSV) with pressure-controlled ventilation (PCV) on lung function, histology and biological markers at two different PEEP levels in mild ARDS in rats...

Exposure to lipopolysaccharides (LPS) causes extensive neutrophilic inflammation in the airways followed by mucous cell hyperplasia (MCH) that is sustained by the anti-apoptotic protein, Bcl-2. To identify inflammatory factor(s) that are responsible for Bcl-2 expression, we established an organ culture system consisting of airway epithelial tissue from the rat nasal midseptum. The highest Muc5AC and Bcl-2 expression was observed when organ cultures were treated with brochoalveolar lavage (BAL) fluid harvested from rats 10 h post LPS instillation...

Macrophages are heterogeneous and their phenotype and functions are regulated by the surrounding micro-environment. Macrophages commonly exist in two distinct subsets: 1) Classically activated or M1 macrophages, which are pro-inflammatory and polarized by lipopolysaccharide (LPS) either alone or in association with Th1 cytokines such as IFN-γ, GM-CSF and produce pro-inflammatory cytokines such as interleukin-1β (IL-1β), IL-6, IL-12, IL-23 and TNF-α, and 2) Alternatively activated or M2 macrophages, which are anti-inflammatory and immunoregulatory and polarized by Th2 cytokines such as IL-4 and IL-13 and produce anti-inflammatory cytokines such as IL-10 and TGF-β...

The imbalance of Th1/Th2 cytokines is well known in recurrent spontaneous abortion (RSA) mouse model. Mesenchymal stem cells (MSCs) possess potent immunoregulatory properties that could modulate the Th1 cytokine responses in benefit of Th2 types. In this study, we aimed to analyze the local and systemic balance of Th1/Th2 cytokines following MSCs therapy. Syngeneic adipose derived MSCs were administered to abortion prone mice during the implantation window. The abortion rate was determined and IL-4, IL-6, IL-12, IL-2, IFN-γ and GM-CSF gene expression was evaluated by Real-Time-PCR in decidual and placental tissues of pregnant mice at day 13...
