Let-7 microRNAs target the lineage-specific transcription factor PLZF to regulate terminal NKT cell differentiation and effector function

Singer and colleagues show that let-7 microRNAs target Zbtb16 mRNA, which encodes the transcription factor PLZF, to modulate PLZF expression during the terminal differentiation of NKT cells into effector subsets. Lethal-7 (let-7) microRNAs (miRNAs) are the most abundant miRNAs in the genome, but their role in developing thymocytes is unclear. We found that let-7 miRNAs targeted Zbtb16 mRNA, which encodes the lineage-specific transcription factor...
