During the revision of this manuscript, Obata-Ninomiya et al. (50) reported a protumoral role of TSLP in colon cancer via a subset of Tregs coexpressing ST2, PD-1, and CTLA-4 that share certain similarities with GATA3+ Tregs that we reported here. The gene discussed is PDCD1; the disease is malignant colon neoplasm.
