Anti-Pseudomonas Exotoxin A-Pe

一般描述
Pseudomonas aeruginosa is a Gram negative bacterium that rarely cause diseases in humans but certain populations, such as cystic fibrosis (CF) or burn wounds patients, are prone to such infections.
Pseudomonas Exotoxin A (PE) is the most potent virulence factor secreted by P. aeruginosa, it is composed of three structural domains, N-terminal domain (I) responsible for the toxin binding to its host cell receptor, middle domain (II) has a role in toxin translocation across the membrane, and C-terminal domain (III) has ADP-ribosylation activity. PE is considered as a selective agent for the elimination of specific cell populations due to its toxin ADP-ribosylation activity resulting in irreversibly shut down of protein synthesis. To reduce the adverse effects of natural PE, Mutated PE was used in several attempts to develop recombinant toxin-antibody or cytokines fusion fragments for therapeutic application including cancer immunotherapy.
