ESKAPE Pathogens
Antimicrobial Peptides
AMPs are small, cationic proteins representing a promising alternative to traditional antibiotics.
Pore formation
Biofilm disruption
AMPs combat bacteria through multiple mechanisms, including disrupting bacterial cell membranes to form pores and
breaking down protective biofilms.
These diverse modes of action make AMPs a powerful tool in the fight against antibiotic-resistant pathogens.
A system that delivers AMPs directly and safely to Pseudomonas aeruginosa.
The Plasmid
contains a Pseudomonas-specific promoter. ensuring AMPs are expressed only in target bacteria.
Two Delivery Systems
Two lipid vesicle delivery systems are engineered to encapsulate plasmids and to specifically target Pseudomonas aeruginosa.
Lipid nanoparticles
Outer membrane vesicle
Pseudomonas aeruginosa
is recognized by the WHO as a high priority pathogen that infects the lung, with urgent need for new therapeutics due to its extremely effective mechanisms for antibiotic resistance.
we plan to transport the specific AMP plasmid with a nebulzer to the lung of the patient where the produced AMPs kill the bacteria from within.
Encapsulated plasmids are delivered to the lung via a nebulizer, creating an aerosol for deep respiratory penetration
Pseudomonas aeruginosa is killed from within
In infected areas, lipid vesicles specifically fuse with P. aeruginosa's cell membrane
The plasmid, carrying the AMP gene, enters the bacterium and integrates it into its genetic machinery
AMPs are produced constitutively from a Pseudomonas-specific promoter, ensuring targeted and continuous expression
The produced AMPs disrupt the bacterial membrane by creating pores or destabilizing its structure
