背景:我们在体内和体外研究了小鼠唾液Muc 19对牙齿感染的保护作用。结果:Muc 19能抑制变形链球菌的牙体感染,并促进其聚集。人类唾液MUC 19的证据。结论:小鼠Muc 19通过清除S.变异人意义:Muc 19在清除中的作用扩展了唾液凝胶形成粘蛋白的公认先天免疫功能。唾液在口腔的先天免疫中起作用,防止牙齿脱矿(即龋齿),这是一种与变形链球菌相关的高度流行的感染性疾病,也是一种与心内膜炎和动脉粥样硬化斑块相关的病原体。形成凝胶的粘蛋白是唾液的主要成分。由于Muc 19是小鼠中主要的唾液凝胶形成粘蛋白,我们研究了Muc 19 −/−小鼠在与S.变异人当挑战S。与野生型相比,Muc 19 −/−小鼠的总光滑和沟表面病变分别高出2倍和1.6倍,而病变的严重程度分别高出6倍和10倍。此外,Muc 19 −/−小鼠的口腔微生物群显示出更高水平的本土链球菌。结果强调了单一唾液成分在唾液先天免疫功能中的重要性。对S. mutans和Muc 19的相互作用(即粘附、聚集和生物膜形成)表明Muc 19与S的聚集性较差。变异体尽管如此,在Muc 19 −/−小鼠的唾液中加入Muc 19后,聚集增强,表明Muc 19通过与结合S的唾液成分形成异型复合物来帮助细菌清除。变形,因此代表了唾液凝胶形成粘蛋白的一种新的先天免疫功能。在人类中,唾液MUC 19的表达尚不清楚。我们发现MUC 19的成绩单在唾液腺的7个科目,并证明MUC 19糖蛋白在腺粘液细胞和唾液。小鼠和人类之间的唾液凝胶形成粘蛋白的表达和功能的异同进行了讨论。
Background: We investigated murine salivary Muc19, in vivo and in vitro, to protect against dental infections. Results: Muc19 attenuates dental infections by Streptococcus mutans and promotes its aggregation. Evidence for human salivary MUC19 is presented. Conclusion: Murine Muc19 helps limit colonization via clearance of S. mutans. Significance: A role for Muc19 in clearance expands upon acknowledged innate immune functions of salivary gel-forming mucins. Saliva functions in innate immunity of the oral cavity, protecting against demineralization of teeth (i.e. dental caries), a highly prevalent infectious disease associated with Streptococcus mutans, a pathogen also linked to endocarditis and atheromatous plaques. Gel-forming mucins are a major constituent of saliva. Because Muc19 is the dominant salivary gel-forming mucin in mice, we studied Muc19−/− mice for changes in innate immune functions of saliva in interactions with S. mutans. When challenged with S. mutans and a cariogenic diet, total smooth and sulcal surface lesions are more than 2- and 1.6-fold higher in Muc19−/− mice compared with wild type, whereas the severity of lesions are up to 6- and 10-fold higher, respectively. Furthermore, the oral microbiota of Muc19−/− mice display higher levels of indigenous streptococci. Results emphasize the importance of a single salivary constituent in the innate immune functions of saliva. In vitro studies of S. mutans and Muc19 interactions (i.e. adherence, aggregation, and biofilm formation) demonstrate Muc19 poorly aggregates S. mutans. Nonetheless, aggregation is enhanced upon adding Muc19 to saliva from Muc19−/− mice, indicating Muc19 assists in bacterial clearance through formation of heterotypic complexes with salivary constituents that bind S. mutans, thus representing a novel innate immune function for salivary gel-forming mucins. In humans, expression of salivary MUC19 is unclear. We find MUC19 transcripts in salivary glands of seven subjects and demonstrate MUC19 glycoproteins in glandular mucous cells and saliva. Similarities and differences between mice and humans in the expression and functions of salivary gel-forming mucins are discussed.
