Measuring and programming cellular mechanobiology
Cellular receptors experience and transmit forces at the piconewton scale (approximately one trillionth the force required to pick up an apple). These minute forces influence many biological processes, including coagulation, cell migration, cancer metastasis, and T cell antigen recognition. The Brockman lab merges chemistry, bioengineering, and imaging approaches to address questions in cellular mechanobiology and cancer immunotherapy. Specifically, we design technologies to measure and manipulate cellular forces at the receptor level. We employ synthetic strategies to chemically synthesize molecular tension probes that transduce piconewton receptor forces into fluorescence. We also leverage fluorescence microscopy techniques, including super-resolution microscopy, to capture fluorescence images that report the location and magnitude of receptor forces (Figure 1). Finally, we seek to design molecular tools that will program the mechanical behavior of cells with a special interest in manipulating the cells of the immune system. Through this work, we seek to impact the fields of mechanobiology, tissue engineering, synthetic biology, and immunotherapy.
