Synthetic, modular polypeptide system for targeted cell therapy strategies

This technology is a fully synthetic, modular cell receptor system that can be used to facilitate the development of cell-based therapies.

Unmet Need: Ability to efficiently modulate endogenous cellular processes for cell therapy strategies

Current cell-based therapies, including chimeric antigen receptor (CAR) T cells, often require modulation of the endogenous cellular systems and responses for therapeutic applications. Adaptation of cellular systems, which have been refined through the evolutionary process, often requires extensive engineering approaches that can be both time-consuming and costly, limiting the application of cell-based therapies. The ability to efficiently adapt and modulate different cellular processes for therapeutic applications using the same system would enhance the application of cell-based therapies; however, there are currently no systems capable of doing so.

The Technology: Chimeric polypeptide system capable of modulating endogenous cellular processes in multiple cell types

This technology adapts the notch signaling pathway, a well characterized and highly conserved signaling pathway, to modulate cellular processes. This technology is a chimeric polypeptide system consisting of four modular components: an extracellular domain, a force sensor domain, a cleavable transmembrane domain, and intracellular signaling domain. The design of the system allows for the modulation of multiple cellular functions in different cell types, depending on the polypeptide composition. As such, this technology could serve as a platform for cell communication research and can facilitate the development of improved cell-based therapies.

This technology has been validated in Drosophila and multiple cell lines, including T and epithelial cells.
