Talk Title: Blood-Brain Barrier Shuttle Peptides, From Discovery to Applications

After dedicating more than 15 years to biomedical research at IRB Barcelona, trying to improve the arrival of drugs to the brain by crossing the blood-brain barrier that protects it. She decided to jump more barriers and be the CEO/CSO of Gate2Brain SL. in order to bring technology closer to patients, a challenge and an honor. Jumping barriers is perhaps the common thread that describes her, combining science and innovation with a new vision on disability, to believe that the impossible only comes later.

Gate2Brain shuttle peptides represent salvage for new or previously rejected CNS drug candidates by providing a way to cross the blood-brain barrier, BBB.

Gate2Brain technology consist on a toolbox of peptides able to cross the BBB and carry compounds covalently attached, including small molecules, peptides, proteins, antibodies, plasmids, siRNA or mRNA loaded nanoparticles, et cetera, that cannot cross this barrier unaided. They have proofed to carry these cargoes in vitro and in vivo. These peptide shuttles use the existing transport mechanisms at the BBB without affecting the normal functioning of these mechanisms and preserving brain homeostasis.

Gate2Brain Technology

By improving the delivery of therapeutic candidate to the CNS, we will ensure immediate impact in many CNS diseases patients. In addition, in a broader perspective, Gate2Brain technology may help to repurpose existing therapies previously rejected because of difficulty to reach the brain, accelerating the translation towards clinical development. Gate2Brain will also result in the application of lower concentrations of therapeutic agent, thereby significantly lowering systemic side effects and reducing the cost of the treatment.

Gate2Brain peptides combine protease resistance, capacity to carry a wide range of cargoes thanks to their versatility, low production costs, and low immunogenic risk. They provide a non-invasive, non-antigenic, permeable, stable, soluble and receptor-specific way to transport drugs across the BBB and into the CNS.
