Using super-resolution microscopy to watch immune cells kill

Cell-contact dependent regulation of immune cell responses plays a vital role in balancing the need for rapid and efficient responses to a wide variety of pathological challenges, while at the same time maintaining self-tolerance. Over the last decade, much research has studied how immune cell interactions are often accompanied by the segregation of proteins into micrometer- and submicrometer-scale domains at an immune synapse.
The emerging new paradigm is that interactions between immune cell receptors, kinases and adaptors are at least in part controlled by transient interactions between supramolecular assemblies. This is a significantly different concept from a linear cascade of individual protein-protein interactions depicted in textbook diagrams of immune receptor signaling pathways.
Here, I will present new data using high- and super-resolution imaging techniques that reveal novel insights into molecular recognition by human Natural Killer cells and how specific effector functions are realized. Our data reveal, for example, that remodelling of the cortical actin mesh occurs at the central region of the NK cell immune synapse during a cytolytic response. This is likely to occur for other types of cell secretion and emphasises the importance of emerging super-resolution imaging technology for revealing new biology.
