Research Interests

Cells can move or change their shape in part because of a protein called actin, which assembles into organized networks of filaments. Actin networks are dynamic in nature and can be remodeled to change their architecture, allowing the cell to rapidly respond to environmental cues or migrate through complex three-dimensional environments. Actin plays a crucial role in a number of cellular processes, from wound healing to the precise wiring of the neuronal circuitry. The Vitriol lab studies the dynamic regulation of actin during cell motility, neural development, and in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). Our approach is largely based on live-cell microscopy and quantitative imaging techniques and we perform these experiments in tissue culture cells, primary motor neurons, and neuromuscular explant cultures. Our goals are to integrate imaging-based cell biology with translational science so that we can both precisely determine how actin networks are assembled and understand how defects in the dynamic regulation of actin contribute to human disease.

Research Projects

R00 NS087104 (NIH/NINDS) Vitriol (PI) 04/15/2015-03/31/2018
Novel mechanisms of actin dynamics underlying cell motility, axon growth, and ALS
The goal of this study is to determine the role that targeting and regulated polymerization of actin monomers plays in cell motility, development and maintenance of the neuromuscular junction, and in ALS pathogenesis.
