title: Visualizing recall immune responses with multi-photon microscopy.
abstract: Multi-photon microscopy has increased our understanding of T-cell behaviour during the initiation of primary immune responses. In this issue of Immunology a study uses real-time imaging of lymph nodes to observe and compare the early events in naive, tolerized and primed CD4 T-cell responses.
