T lymphocytes receive activation signals during their encounters with antigen-bearing dendritic cells (DCs) in secondary lymphoid organs. With the recent application of two-photon imaging to visualize immune responses as they happen, the dynamics of T cell-DC interactions have been dissected in several mouse models. As we are integrating the results of these new studies, we are learning that the dynamics of T cell-DC interactions are regulated by multiple immunological parameters and, most importantly, that the spatiotemporal characteristics of these cell-cell contacts encode part of the T-cell fate.
