Anti-tumor Mechanism and Clinical Application of Pseudomonas Aeruginosa-Mannose-Sensitive Hemagglutinin / 医药导报

ABSTRACT

The application of Pseudomonas aeruginosa-mannose-sensitive hemagglutinin(PA-MSHA)in the field of an-titumors has been increasing.PA-MSHA has been found to promote tumor cell apoptosis,inhibit tumor cell invasion and migration,differentiation,and change drug resistance and epithelial-mesenchymal transformation(EMT)by inhibiting the EGFR pathway.Meanwhile,PA-MSHA also enhances the immune killing and inhibition of macrophages and T cells to tumor cells through toll-like receptors(TLRs).In this paper,we reviewed the reported anti-tumor mechanism and clinical application of PA-MSHA,suggesting that PA-MSHA may alter the glycosylation of EGFR and TLR proteins by acting on the regulatory process of the cellular mannosy-lation process.PA-MSHA can act on cell membrane proteins,including more receptors with high-mannosylation of signaling path-ways.Elucidating the deep relationship between PA-MSHA and mannosylation is of great significance for the mechanism research and clinical application of PA-MSHA.
