Webb6 juli 2024 · Furthermore, oral as well as respiratory bacteria appear to induce the proinflammatory cytokines release from respiratory epithelial cell lines in vitro . Oral bacteria may be responsible for altering the local microenvironment, thereby facilitating the onset and/or progression of respiratory disease in susceptible individuals [ 54 ]. WebbIn response to any infection, there is an increase in production of mucus (which contains the potent antibacterial enzyme lysozyme) by the respiratory epithelium . Along with increased mucus production, there is dilatation of mucosal blood vessels, which brings white blood cells and antibodies to the area, all of which contribute to the mucopurulent …
