Quantum dots as tools to probe the role of self-antigen display in generating tolerance
Hess et al  use quantum dots (green) to control the density of self-antigen displayed at the molecular scale. This approach provides a tool to probe the role of ligand number and density during tolerance induction in mice. The precisely displayed self-molecules are internalized by antigen-presenting cells (clear) in lymph nodes that polarize inflammatory T cells (orange) to regulatory T cells (developing green region). Precision display of donor-derived peptides on nanoparticles may be useful in promoting tolerance for transplantation. Authors: Christopher M. Jewell, PhD, Krystina L. Hess, Demin Liu.
