The immune system is like a computer, which uses chemical signals, instead of electrical signals. When the immune system sees a potential threat, it needs to integrate information from multiple sources, to decide how to respond. Making the correct decision is important for fighting infections, killing cancer cells, and avoiding autoimmune diseases.
To manipulate a computer circuit, you need to deliver time-dependent electrical signals to a specific location in the circuit. To guide the immune system into attacking cancer cells, my lab has been developing new technologies for timed local delivery of chemical signals. Spatial control is achieved by image guided delivery into tumor versus lymph node. Temporal control is achieved by programmable multi-drug release kinetics from the drug delivery implant. Different drugs can then be delivered into specific locations at specific times, to convince the immune system to attack cancer antigens.
The latest publication from my lab is a new intratumoral immunotherapy delivery platform, which achieves 6 days of intratumoral drug release, from a single injection. Tumors can be “painted” with drug using a needle, and the drug stays exactly where it’s injected, maximizing immune activation in the tumor, while reducing systemic toxicity.
