This research identifies the deubiquitinase USP10 as a vital regulator of T cell development and a key driver of T-cell acute lymphoblastic leukemia (T-ALL). By analyzing mouse models and human clinical samples, the authors demonstrate that USP10 stabilizes the transcription factor SOX4, preventing its degradation to ensure the rapid proliferation of thymocytes. The study reveals a genetic circuit where MYC signaling induces USP10 expression, which in turn sustains the cellular expansion necessary for immune maturation or, when dysregulated, malignant transformation. Crucially, the authors…
