Healthy immune cell behavior requires sensitive and robust control over the processes that regulate signal transduction. In this work we employ single molecule fluorescence imaging techniques to quantify adapter protein recruitment, lateral mobility, receptor aggregation, and cytoskeletal organization to create a better understanding of many key processes in immune cell regulation. We focus on understanding the initiating events in FceRI signaling in mast cells. Mast cell signaling encompassing a wide array of cellular outcomes including calcium flux, release of pre-formed inflammatory mediators and the production of cytokines. Careful control over appropriate reactions to external antigens is necessary for mast cells …
