The European Network on Anti-Cancer Immuno-Therapy Improvement by modification of CAR and TCR Interactions and Nanoscale Geometry (EN-ACTI2NG), formed by 12 academic, clinical and industrial institutions from Spain, Austria, Germany, The Netherlands and the United Kingdom offers a multidisciplinary training for 10 early stage researchers in the development and analysis of engineered tumor-specific immune receptors. At TU Wien, we will use single molecule tracking and superresolution microscopy to quantify the interactions between the different membrane proteins at milliseconds time resolution.
