BACKGROUND Interferon-γ (IFN-γ) plays a crucial role in Mycobacterium tuberculosis induced pleural responses. Interleukin (IL)-33 up-regulates the production of IFN-γ. We aimed to identify whether an association between pleural IL-33 levels and tuberculous pleurisy exists and determine its diagnostic value. METHODS Pleural IL-33, ST2 (a receptor of IL-33), adenosine deaminase (ADA), and IFN-γ...
Interleukin-33 (IL-33), a newly-discovered cytokine belonging to the IL-1 family, serves an important role in inflammation. However, it is not clear whether IL-33 is of clinical significance in hepatocarcinogenesis. The present study was designed to investigate the role of IL-33 during oncogenesis and development of hepatocellular carcinoma (HCC). IL-33 protein expression was detected in 76 HCC...
BACKGROUND Interleukin-33 (IL-33) activates group 2 innate lymphoid cells (ILC2), resulting in T-helper-2 inflammation in bronchial asthma. Airway epithelial cells were reported as sources of IL-33 during apoptosis and necrosis. However, IL-33 is known to be from sources other than airway epithelial cells such as leukocytes, and the mechanisms of IL-33 production and release are not fully under...
Objectives: Epithelial-mesenchymal transition (EMT) of renal tubular epithelial cells (RTECs) is a pathogenic factor for interstitial fibrosis (RIF). Interleukin-33 (IL-33) related to the occurrence and development RIF, but underlying mechanism remains unclear. Here, we investigated whether IL-33 mediates EMT RTECs by activating NF-κB/Twist1 signalling pathway. Methods: In vivo, RIF animal mode...
Alternatively activated macrophages (AAM) play a crucial role in type 2 immunity. Mice deficient in ST2, a receptor for the latest member of the IL-1 family, IL-33, have impaired type 2 immune responses. We therefore reasoned that IL-33/ST2 signaling may be involved in the differentiation and activation of AAM during airway inflammation. We report here that IL-33 changed the quiescent phenotype...
Basophils are thought to play pivotal roles in allergic inflammation through rapid release of chemical mediators in addition to sustained production of Th2 cytokines, including IL-4. A newly identified cytokine, IL-33, has been recognized as one of the key cytokines enhancing Th2-balanced immune regulation through its receptor, ST2. The present study was conducted to elucidate whether IL-33 act...
