摘要

肺炎球菌是细菌性和侵袭性肺炎球菌感染的主要原因。破坏肺泡上皮屏障是侵袭性肺炎球菌感染发病机制的重要步骤。表皮生长因子受体(EGFR)维持肺泡上皮屏障的完整性。在这项研究中，我们发现，分泌性肺炎球菌分子降低EGFR的分子量而不降解肽，并通过EGFR抑制肺泡上皮细胞的增殖。

Pneumococcus downregulates the molecular weight of the extracellular domain of the epidermal growth factor receptor of alveolar epithelial cells

Pneumococcus is themajor cause of bacterial and invasive pneumococcal infections. Disrupting the alveolarepithelial barrier is an important step in the pathogenesis of invasivepneumococcal infections. The epidermal growth factor receptor (EGFR) maintainsthe integrity of the alveolar epithelial barrier. In this study, we showed that secretory pneumococcal molecules decrease the molecular weight of EGFR without peptide degradation and inhibit alveolar epithelial cell proliferation via EGFR.
