CD247 and Autoimmunity: From the set of miRNA-mRNA interactions that were found during the development of thymocytes into PILs, we identified interactions between miR- 202-3p and the Ccr7 chemokine receptor and Cd247 (Cd3 zeta chain) mRNAs, which were previously found to be involved in the control of aggressive autoimmunity in T1D in NOD mice.
