Using Confocal Microscopy to Investigate Intracellular Trafficking of Toll-Like Receptors
Toll-like receptors (TLR) survey the extracellular space, cytoplasm, and endosomal compartments for signs of infection or tissue injury. Over the past decade, it has become evident that TLR activation and signal transduction can be regulated by subcellular compartmentalization of both the receptors and their downstream signaling components. Immunofluorescence and/or overexpression of fluorescently “tagged”’ proteins teamed with confocal microscopy presents a powerful technique for studying the spatial organization of TLRs, their signaling mediators, and the dynamic processes they activate. This chapter details the common methods for determining the subcellular location of TLRs in both live and fixed cells.
