OBGATE is an ERC Starting Grant funded by the European Research Council Executive Agency.

Many impairing illnesses raging from metastatic cancers to neurodegenerative diseases affect the brain. Unfortunately, delivery of therapeutics to the brain is highly challenging due to the blood-brain barrier (BBB). Despite decades of research, no safe and efficient strategy to overcome this barrier has reached clinical application.

We propose in OBGATE a concept that will revolutionize brain transport: creating a new orthogonal receptor to mediate transport across the BBB. Numerous molecules have been developed to achieve brain delivery via receptor-mediated transport. However, delivery is very limited presumably because no receptor  combines 3 key features: high transport efficiency, high expression on the BBB, and low expression on peripheral tissues. The greatest limitation of current efforts is trying to solve both selectivity and efficient transport in a single delivery vehicle. Our unprecedented approach is based on dissecting this problem in two: increasing transport efficiency with the new orthogonal receptor OBGate and addressing selectivity with a highly efficient targeted vehicle to express the receptor only at the  BBB. As an example to prove the efficiency of our system we will aim to deliver biotherapeutics for the treatment of brain metastatic breast cancer. Overall, we will open a new gate to the brain that is poised to be paradigm-breaking in the treatment of neurological diseases.
