Absence of Toll-like receptor 7 protects mice against

Jul 01, 2021 · TLR7 eion was significantly elevated in WT mice after Pseudomonas aeruginosa infection. TLR7 / mice demonstrated enhanced survival, bacterial clearance, leukocyte infiltration, and macrophages phagocytic activity, and decreased pathology and capillary leakage. Besides, improved survival and bacterial clearance were observed in WT Cathelicidin Host Defence Peptide Augments Clearance of Jun 02, 2014 · We demonstrate that therapeutically administered synthetic LL-37 peptide can enhance the clearance of P. aeruginosa from the murine lung, in the absence of demonstrable direct microbicidal effects, and can induce an upregulation of the early neutrophil response to pathogen in the lungs that is dependent both upon the presence of the peptide and the pathogen.

Enhanced autophagy promotes the clearance of

Among the normal wounds infected with P. aeruginosa, the colony number in the normal wounds with P. aeruginosa and interfered with rapamycin was significantly decreased and the clearance of P. aeruginosa was increased on day 3, compared with that in the normal wounds infected with P. aeruginosa (*P<0.05). In the gentamicin interfered wounds, the rate of increase in colony number was slower, and the number of colonies began to decrease Frontiers Antibodies Against Pseudomonas aeruginosa Mar 31, 2021 · Introduction. Pseudomonas aeruginosa is an opportunistic gram-negative bacterium that is ubiquitous in the environment. Normally, serious P. aeruginosa infections are prevalent in immunocompromised individuals, including patients with neutropenia, severe burns, cystic fibrosis (CF), and chronic obstructive pulmonary disease (COPD) (1, 2).As a consequence, P. aeruginosa is a Frontiers Bactericidal/Permeability-Increasing Protein

  • IntroductionMethodsResultsDiscussionData Availability StatementEthics StatementAuthor ContributionsFundingConflict of InterestAcknowledgmentsPolymorphonuclear cells or neutrophils (PMNs) are an essential component of innate immunity against Pseudomonas aeruginosa infection (1, 2). Neutropenic mice are more susceptible to P. aeruginosa-related mortality (2), while humans deficient in neutrophil-mediated antimicrobial mechanisms (typically altered phagocytic function) have markedly increased susceptibility to P. aeruginosa infection (3, 4). Thus, immunity against P. aeruginosa is dependent on neutrophil-mediated phagocytosis. Chronic PCD1d-dependent macrophage-mediated clearance of CD1d-dependent macrophage-mediated clearance of Pseudomonas aeruginosa from lung CD1d-restricted T cells are implicated as key players in host defense against various microbial infections. However, the mechanisms involved and the role they play, if any, at the mucosal surfaces where pathogenic infections are initiated is unknown.

    Dec 18, 2017 · 1. Introduction. Pseudomonas aeruginosa, a ubiquitous environmental gram-negative microorganism that is found in soil and aquatic environments, is one of the major opportunistic human pathogens.P. aeruginosa can cause chronic infections in the context of damaged or abnormal airway epithelium and compromised local pulmonary clearance mechanisms. Chronic respiratory infections with P. aeruginosa Enhanced Clearance of Pseudomonas aeruginosa by Our study shows that clearance of P. aeruginosa (PAO1) is enhanced by PPAR glucose) containing 10% heat-inactivated FBS and 100activation in the macrophages and lungs of miceinfectedwithPAO1.Byusingagene-silencingapproach,we showthattheimmunostimulatoryeffectsofPPAR aremediated throughtheinductionofPON
