Using Light To Dissect Mechanisms Of Septin Recruitment, Shreya Chandrasekar

Dissertations

Cells interpret biochemical and mechanical signals through dynamic regulation of the cytoskeleton and adhesion complexes, enabling key processes such as shape adaptation, force generation and migration. As these signals vary in both time and space, they can be challenging to resolve using traditional bulk assays. To overcome this limitation, we employ light-based optogenetic tools to reversibly modulate biochemical signals and mechanical equilibrium within cells. Specifically, we use the iLID optogenetic approach to locally activate signaling and manipulate contractility within the cytoskeleton for the purpose of investigating the role of RhoA and contractility on septin organization and adhesion protein localization. We …
