Brief summary: In this experimental study, immunomodulatory microparticles, consisting of encapsulating self-antigens with rapamycin, were injected into mouse lymph nodes to protect against type 1 diabetes (T1D) and islet graft rejection. Antigens and rapamycin were both required for maximal efficacy and they induced durable tolerance, accompanied by expansion of antigen-specific regulatory T cells (Treg) in both treated and untreated lymph nodes.Antigen...
