Prof. Barbara Baird will visit the Chemistry Department this Tuesday to discuss her work in the areas of Chemistry and Biophysics: "Zooming in on Spatial Control of Receptor Mediated Cellular Responses"
Abstract:
Cells respond to their physical environment and to chemical stimuli in terms of collective molecular interactions that are regulated in time and space. Small molecules may engage specific receptors to initiate a transmembrane signal, and the system amplifies this nanoscale interaction to microscale assemblies within the cell and often to longer length scales involving surrounding tissue and ultimately the whole organism. A striking example of signal integration over multiple length scales is the allergic immune response. IgE receptors (FcεRI) on mast cells are the gatekeepers of this response, and this system has proven to be a valuable model for investigating receptor-mediated cellular activation. Spanning the range of cellular responses we use super resolution fluorescence localization microscopy to investigate the earliest signaling events and ligands patterned in micron size features together with confocal microscopy to investigate early and later events. My talk will describe our efforts to integrate physical, biological, and nanotechnology approaches to examine the spatial orchestration of cellular responses on the length scales at which they occur.
