MUC5AC and infection: , Furthermore, proteinssuch as mucin-7, proline-rich glycoproteins, and amylase have beenreported to mediate the adhesion of oral streptococci, while S. aureus specifically binds to mucin-7and immunoglobulins A and G., Comparatively, the adsorption of lactotransferrin on implant surfacesmay prevent infection as it inhibits the growth of P. gingivalis and P. intermedia.
