CD1d-restricted invariant natural killer T (iNKT) cells are innate-like T lymphocytes that play fundamental roles in cancer, autoimmunity, and infections. iNKT cells acquire effector functions already in the thymus, because of a distinct developmentally regulated genetic program that is critically controlled by miRNAs. Our study unveils the unexpected requirement for miRNA-dependent fine-tuning of TGF-? signaling in the control of iNKT cell development and functional differentiation. The targeting of a lineage-specific cytokine signaling by miRNA represents a previously unknown level of developmental regulation in the thymus. Furthermore, our study provides a comprehensive atlas of miRNA-regulated molecular pathways involved in iNKT cell ontogenesis, and highlights molecular pathways targeted by defined miRNAs that are predicted to be involved in the development and maturation of CD1d-restricted iNKT cells.
