Research Title: Single-Cell Dissection of Neuronal Organization in a Regenerative Brain

Research Description: Recent developments in neuroregenerative studies present immunological responses as showing both positive and negative regulation of neuronal regrowth. Such information can be untangled in the planarian flatworm, which exhibits extraordinary neuroregenerative ability, although the cleanup processes by glial and immune cells in this system remain unknown.Photo of graduate student Margarita Khariton in the lab, using a small machine and a pipette. Characterization of these cellular cleanup roles may uncover novel mechanisms that allow for such robust neuroregeneration in the planarian. Further implication of these functional modules in the neuroregeneration of a vertebrate, the zebrafish, will help to reveal regulatory mechanisms that are transferable across species to rebuild neuronal networks after severe injury.  Margarita’s project combines engineering and developmental biology by developing a set of new tools that will integrate biological systems between basal invertebrates and complex vertebrates.
