Initiation of a gonococcal infection involves attachment of Neisseria gonorrhoeae to the plasma membrane of an epithelial cell in the mucosal epithelium and its internalization, transepithelial trafficking, and exocytosis from the basal membrane. Piliation and expression of certain Opa proteins and the immunoglobulin A1 protease influence the transcytosis(More)
We previously demonstrated that the Neisseria IgA1 protease cleaves LAMP1 (lysosome-associated membrane protein 1), a major integral membrane glycoprotein of lysosomes, thereby accelerating its degradation rate in infected A431 human epidermoid carcinoma cells and resulting in the alteration of lysosomes in these cells. In this study, we determined whether(More)
