Two years ago, Jackson and his colleagues in the Chen Lab co-developed a technology called Slide-tags, which enabled scientists to map the location of cells within tissues in standard single-cell experiments. Now, Jackson will use Slide-tags to gain a better understanding of how hubs form. Specifically, he’ll apply different combinations of immune-guiding chemical signals and track how they shape hub formation. The resulting data will inform his efforts to engineer immune hubs that can potentially be used in cancer treatments.
