Immune monitoring in cancer, vaccination, infection, and autoimmune disorders requires detection of certain antigen-specific immune cells, yet because they are few and far between in the blood stream, finding them is a challenge.A platform from the Hammond and Irvine labs cleverly exploits memory T cells to induce circulating immune cells of interest to accumulate in the skin, which can then be sampled non-invasively by a microneedle patch. Recently published in Nature Biomedical Engineering, earlier work on this approach was supported by the Bridge Project and appears in the KI Image Awards Archive.
