title: Dynamic intravital imaging of cell-cell interactions in the lymph node.
abstract: In the last decade, the application of 2-photon intravital microscopy as a tool to study cell interactions in different areas of the immune system has offered an unprecedented opportunity to understand the complexity of cell behavior in relation to immune functions. In this review we describe the latest advances in the field of live imaging in the lymph nodes, grouping the different cell populations in 2 compartments according to their motility: the sessile compartment, which is formed by resident cells of stromal origin, macrophages, and resident dendritic cells, and the motile compartment, which is mainly formed by T and B lymphocytes. Here we review how the use of in vivo imaging has contributed to our understanding of the role of these cells in the initiation of the immune response in the draining lymph nodes.
