Interleukin-4 enhances pulmonary clearance of Pseudomonas aeruginosa.
To determine the effects of interleukin-4 (IL-4) on bacterial clearance from the mouse lung, transgenic mice expressing IL-4 in respiratory epithelial cells under the control of the Clara cell secretory protein promoter (CCSP-IL-4 mice) were infected intratracheally with Pseudomonas aeruginosa. Survival of CCSP-IL-4 mice following bacterial administration was markedly improved compared with tha...
متن کاملNKG2D is critical for NK cell activation in host defense against Pseudomonas aeruginosa respiratory infection.
Pseudomonas aeruginosa is a major cause of nosocomial respiratory infections. The eradication of P. aeruginosa from the lung involves the orchestrated actions of the pulmonary epithelium and both resident and recruited immune cells. The NKG2D receptor is constitutively expressed on the surface of circulating and tissue-resident NK cells (and other cytotoxic lymphocytes), and is capable of contr...
متن کاملRegulation of ligands for the NKG2D activating receptor.
NKG2D is an activating receptor expressed by all NK cells and subsets of T cells. It serves as a major recognition receptor for detection and elimination of transformed and infected cells and participates in the genesis of several inflammatory diseases. The ligands for NKG2D are self-proteins that are induced by pathways that are active in certain pathophysiological states. NKG2D ligands are re...
متن کاملLung epithelial MyD88 drives early pulmonary clearance of Pseudomonas aeruginosa by a flagellin dependent mechanism.
Pseudomonas aeruginosa is a flagellated pathogen frequently causing pneumonia in hospitalized patients and sufferers of chronic lung disease. Here we investigated the role of the common Toll-like receptor (TLR) adaptor myeloid differentiation factor (MyD)88 in myeloid vs. lung epithelial cells in clearance of P. aeruginosa from the airways. Mice deficient for MyD88 in lung epithelial cells (Sft...
متن کاملCutting edge: enhanced pulmonary clearance of Pseudomonas aeruginosa by Muc1 knockout mice.
MUC1 (MUC1 in human and Muc1 in nonhumans) is a membrane-tethered mucin that interacts with Pseudomonas aeruginosa (PA) through flagellin. In this study, we compared PA pulmonary clearance and proinflammatory responses by Muc1(-/-) mice with Muc1(+/+) littermates following intranasal instillation of PA or flagellin. Compared with Muc1(+/+) mice, Muc1(-/-) mice showed increased PA clearance, gre...
