-- Researchers Show Combining Universal Cell Sensor with T Cells Creates Cellular “Robots” that Search and Precisely Treat Complex Diseases --
-- Preclinical Results Published in Cell Illustrate Next Generation of Precision-Designed Immunotherapies –
SAN FRANCISCO, Calif. – September 29, 2016 – Cell Design Labs, Inc. today announced the publication of key preclinical data demonstrating that by engineering immune cells (T cells) with a synthetic Notch receptor (synNotch™), the T cell becomes a programmable living machine able to combat cancer and other diseases.
“In this paper, we demonstrate our ability to easily and flexibly program what an immune cell senses and how it responds,” said Wendell Lim, Ph.D., Scientific Founder of Cell Design Labs and Professor and Chair of the Department of Cellular and Molecular Pharmacology at UC San Francisco (UCSF) and an Investigator of the Howard Hughes Medical Institute. “Combining this universal sensor, synNotch, and immune cells gives us the capability to engineer cellular “robots” capable of patrolling the body to detect and precisely treat complex diseases. These robots can be customized with different features and functions, which when triggered by appropriate signals, can deploy diverse weapons against disease.”
Dr. Lim continued, “Specifically, we have shown that T cells can be programmed to deliver and produce therapeutic agents at the site of a tumor to treat disease. Importantly, the local production of these molecular therapies by the therapeutic immune cell results in a radically new approach – one that is both more effective and far safer than systemic infusion of therapeutics being used today.”
The results of the study, entitled ‘Engineering T cells with customized therapeutic response programs using synthetic notch receptors,’ [link to title] were published in the peer-reviewed journal Cell online today, and will appear in the October 6, 2016 print edition. In the paper, researchers demonstrated that by integrating immune cells (T cells) with a synthetically created universal molecular sensing system (synNotch receptor), they created, in essence, living programmable micro-devices.

In the paper, researchers demonstrated that by integrating immune cells (T cells) with a synthetically created universal molecular sensing system (synNotch receptor), they created, in essence, living programmable micro-devices. The researchers showed that these turn on new genes. By engineering different aspects of the synNotch scaffold, diverse sensing/response behavior results. This video provides an audiovisual illustration of this novel technology.
By engineering Notch, it is possible to create a programmable immune cell. When this reprogrammed cell binds to its sole intended target (i.e. a cancer cell), it triggers a specific molecular activity. These activities include delivering a checkpoint inhibitor to combat cancer, inducing a customized cytokine profile or encouraging T cells to differentiate into specific subtypes to convey long-term protection against cancer recurrence. The synNotch receptor conveys sensor functionality while the T cell ensures the cell’s ability to roam throughout the body to find its target.
Technology in Context of Current Clinical Oncology Approaches
The most direct application for today’s publication is CAR T technology. CAR T cells redirect natural T cells to antigens, or molecular markers, found primarily on cancer cells. An unintended consequence of this approach is an immunologic meltdown coupled with collateral damage to related normal tissue. Moreover, CAR T cells have not proved potent enough to attack solid tumors, such as pancreatic, breast and colorectal cancers. In contrast, with this novel technology, a physician will be able to deploy a precise therapeutic response program specifically targeted against the tumor, based on a precision recognition profile. Moreover, by arming T cells with locally delivered therapeutics, physicians can increase the potency of the T cells without increasing side effects. It not only provides the best of current immunotherapy (CAR T cells and checkpoint inhibitors), it offers a highly customized solution that has the potential to be more potent, specific and safe.
