RNA sensors are a cutting edge tool in synthetic biology for probing complex molecular pathways and creating “smart” molecular circuits in cells. This team leverages state-of-the-art synthetic biology tools to understand how oligodendrocytes contribute to Alzheimer’s disease and other demyelinating disorders.

Myelin, traditionally thought of as the brain's electrical insulator, has emerged as an active and dynamic regulator of brain functions including neuroprotection, learning, and memory. Myelin dysfunction and loss is increasingly found to be central to brain aging and neurodegenerative diseases including Alzheimer's.

Schwann cells (SCs) sort and myelinate peripheral axons, and impairments in either process can cause long-term disability. There are no therapeutic strategies for targeting SC dysfunction, underscoring the need to investigate mechanisms of sorting and myelination. Both processes require highly motile SC cytoplasmic protrusions, but the basis of this motility is unclear.
