“…Indirect effects due to increased cytokine production could occur in parallel, some cytokines being secreted earlier due to direct binding of GRP to GRPR on target cells, amplifying proinflammatory signals via multiple cytokinespecific receptors. It is not known what limits these responses, except perhaps anti-inflammatory cytokines IL-10, IL-12(p40), and IFN-γ (53).…”

Gastrin-releasing peptide (GRP) is synthesized by pulmonary neuroendocrine cells in inflammatory lung diseases, such as bronchopulmonary dysplasia (BPD). Many BPD infants develop asthma, a serious disorder of intermittent airway obstruction. Despite extensive research, early mechanisms of asthma remain controversial. The incidence of asthma is growing, now affecting >300 million people worldwide. To test the hypothesis that GRP mediates asthma, we used two murine models: ozone exposure for air pollution-induced airway hyperreactivity (AHR), and ovalbumin (OVA)-induced allergic airway disease. BALB/c mice were given small molecule GRP blocking agent 77427, or GRP blocking antibody 2A11, before exposure to ozone or OVA challenge. In both models, GRP blockade abrogated AHR and bronchoalveolar lavage (BAL) macrophages and granulocytes, and decreased BAL cytokines implicated in asthma, including those typically derived from Th1 (e.g., IL-2, TNFα), Th2 (e.g., IL-5, IL-13), Th17 (IL-17), macrophages (e.g., MCP-1, IL-1), and neutrophils (KC = IL-8). Dexamethasone generally had smaller effects on all parameters. Macrophages, T cells, and neutrophils express GRP receptor (GRPR). GRP blockade diminished serine phosphorylation of GRPR with ozone or OVA. Thus, GRP mediates AHR and airway inflammation in mice, suggesting that GRP blockade is promising as a broad-spectrum therapeutic approach to treat and/or prevent asthma in humans.

“…Unlike IL-4, IL-13 does not appear to be important during the initial differentiation of CD4 + naive T-cells into TH2 cells because there are no functional IL-13 receptors on human T cells (28)(29)(30). Instead, IL-13 is related to the fibrosis of lesion tissue in various types of chronic inflammation because IL-13 receptors are expressed on endothelial cells, fibroblasts and smooth muscle cells.…”

“…The process of airway inflammation involves various cells types, such as eosinophils, mast cells, epithelial cells, lymphocytes and DCs. Th2 cells have been shown to play a predominant role in allergic asthma and Th2 cytokines, such as IL-4, IL-5 and IL-13, exacerbate disease severity [3,4]. IL-33, the recently discovered Th2 cytokine, is found at high levels in the plasma of asthmatic patients [5,6] and in the lungs of mice during experimental allergic asthma [7,8].…”

IL‐33‐activated dendritic cells are critical for allergic airway inflammation

IL-33, a new member of the IL-1 family cytokine, is involved in Th2-type responses in a wide range of diseases and signals through the ST2 receptor expressed on many immune cells. Since the effects of IL-33 on DCs remain controversial, we investigated the ability of IL-33 to modulate DC functions in vitro and in vivo. Here, we report that IL-33 activates myeloid DCs to produce IL-6, IL-1b, TNF, CCL17 and to express high levels of CD40, CD80 OX40L and CCR7. Importantly, IL-33-activated DCs prime naive lymphocytes to produce the Th2 cytokines IL-5 and IL-13, but not IL-4. In vivo, IL-33 exposure induces DC recruitment and activation in the lung. Using an OVA-induced allergic lung inflammation model, we demonstrate that the reduced airway inflammation in ST2-deficient mice correlates with the failure in DC activation and migration to the draining LN. Finally, we show that adoptive transfer of IL-33-activated DCs exacerbates lung inflammation in a DC-driven model of allergic airway inflammation. These data demonstrate for the first time that IL-33 activates DCs during antigen presentation and thereby drives a Th2-type response in allergic lung inflammation. IntroductionAllergic asthma is a chronic disorder characterized by eosinophilic airway inflammation, mucus hypersecretion, antigenspecific-IgE antibodies, airway remodeling and increased airway hyperreactivity [1,2]. The process of airway inflammation involves various cells types, such as eosinophils, mast cells, epithelial cells, lymphocytes and DCs. Th2 cells have been shown to play a predominant role in allergic asthma and Th2 cytokines, such as IL-4, IL-5 and IL-13, exacerbate disease severity [3,4]. IL-33, the recently discovered Th2 cytokine, is found at high levels in the plasma of asthmatic patients [5,6] and in the lungs of mice during experimental allergic asthma [7,8].IL-33 is a member of IL-1 family [9][10][11]. Like IL-1b or IL-18, IL-33 is synthesized as a precursor and can be cleaved by caspase-1 and 3 but the cleavage products are biologically less active than the precursor [12,13]. In contrast to the other IL-1 family members, IL-33 is mainly expressed in non-hematopoietic cells such as fibroblasts, epithelial cells and endothelial cells [10,14,15]. Because of its nuclear localization sequence, IL-33 is usually present in the nucleus, where it acts as a potential transcriptional repressor [16]. Recently, IL-33 has been shown to be released from necrotic cells and may act as an alarmin in a similar manner to IL-1a [17] or high mobility group box1 protein HMGB1 [18,19]. [14]. In accordance with its Th2 functions, administration of IL-33 into naive mice induces severe inflammation in the lung and digestive tract with elevated levels of IL-4, IL-5 and IL-13, splenomegaly and increased serum Ig [10]. In vitro, IL-33 has also been reported to polarize naive CD4 1 T cells to produce IL-5 and IL-13, but not . Polarization of this atypical Th2 population is independent of IL-4, STAT6 and GATA3. On macrophages, IL-33 amplifies IL-13-mediated polarization...
