Scientists become filmmakers to decipher immunity
...T cells remain in contact with dendritic cells for prolonged periods. After that time, the T cells become activated, separate from the dendritic cells, and migrate away. The study provides a new glimpse into key steps in early immune responses and paves the way for future work on T-cell activation.
