The aims of this study were to investigate kinin receptor expression on eosinophils of asthmatic and healthy subjects and to assess the effects of kinin stimulation on eosinophils, which were isolated from peripheral blood of asthmatic (n=27) and healthy subjects (n=14). Kinin B(1) and B(2) receptors (B(1)R and B(2)R, respectively) and mRNA expression were investigated by quantitative confocal microscopy, flow cytometry, and RT-PCR. Intracellular Ca(2+) was assessed by live-cell fluorescence confocal microscopy. Production of cysLT and eosinophil migration in response to BK and Lys-des[Arg(9)]-BK were assessed. Eosinophils expressed kinin B(1)R and B(2)R mRNA and proteins. Quantitative immunofluorescence analysis indicated that expression of B(1)R and B(2)R proteins was significantly greater in eosinophils of asthmatic patients compared with those of nonasthmatic subjects. However, kinin B(1)R and B(2)R mRNA expression did not differ significantly between these groups. Expression of kinin B(1)R and mRNA was decreased in patients using high doses of inhaled corticosteroids and in eosinophils treated with a corticosteroid in vitro. Kinin B(1) and B(2) agonists up-regulated expression of their respective receptors but did not increase intracellular Ca(2+) or the production of cysLT or enhance eosinophil migration significantly. Up-regulation of kinin receptor expression in eosinophils of asthmatic patients may be a consequence of inflammation, whereby enhanced release of kinin peptides has a positive-feedback effect on kinin receptor expression. Importantly, anti-inflammatory corticosteroids down-regulated the expression of the kinin B(1)R."xsd:string |
