OptoProfilin: A Single Component Biosensor of Applied Cellular Stress.

The actin cytoskeleton is a biosensor of cellular stress and a potential prognosticator of human disease. In particular, aberrant cytoskeletal structures such as stress granules formed in response to energetic and oxidative stress are closely linked to ageing, cancer, cardiovascular disease, and viral infection. Whether these cytoskeletal phenomena can be harnessed for the development of biosensors for cytoskeletal dysfunction and, by extension, disease progression, remains an open question.

OptoProfilin: A Single Component Biosensor of Applied Cellular Stress.

The actin cytoskeleton is a biosensor of cellular stress and a potential prognosticator of human disease. In particular, aberrant cytoskeletal structures such as cofilin-actin rods and stress granules formed in response to energetic and oxidative stress are closely linked to neurodegenerative diseases such as Alzheimer's, Parkinson's, and ALS. Whether these cytoskeletal phenomena can be harnessed for the development of biosensors for cytoskeletal dysfunction and, by extension, neurodegenerative disease progression, remains an open question.
