New Finding
Tech Advance
This study introduces two photon-videomicroscopy to the study of T cell and B cell motility, and T cell responses to specific antigen, in explanted lymph nodes. Striking differences in the motilities of T and B cells within the lymph node architecture are directly observed. The kinetics and character of the response of T cells to specific antigen are defined.

Confirmation
Tech Advance
Modern microscopic methods, especially two-photon laser scanning photography, allow direct visualisation of live fluorochrome-labelled lymphocytes trafficking in lymphoid tissues. Differentially labelled T and B cells move about in complex trajectories after entering their characteristic regions of a lymph node. The presence of an antigen specific for labelled T lymphocytes induces perturbations in their movement. In particular, stationary clusters and dynamic swarms form. Subsequently, the cells enlarge and divide. Without breaking radical new ground conceptually, these results demonstrate the validity of concepts of lymphocyte behaviour obtained with disaggregated cell mixtures. They further demonstrate the extraordinary power of the new microscopy.

Tech Advance
This is a very impressive advance for the live tracking of ongoing antigen-specific immune responses, and could be a first step in revolutionizing non-invasive imaging techniques for understanding immunity. Direct visualization of antigen-specific T cells and antigen-presenting cells in lymph nodes and possibly other organs in the future will improve our comprehension of the immune system.
