The 19th International Congress of Immunology (IUIS), held in Vienna from August 17 to 22, encompasses 5 days of scientific sessions, symposia, and workshops covering basic, translational, and clinical immunology. Several sessions, including those on immune cell signaling, tissue-resident memory T cells, and macrophage heterogeneity directly benefit from advanced, label-free imaging methods. Our technology aligns closely, offering non-invasive, high-resolution visualization of immune cell morphology, dynamics, and interactions, critical for understanding cell signaling and behavior without fluorescence or staining. If you are attending the conference, make sure to visit our Booth 26 and talk to our representatives to find out how we can advance your research.
