We show that an impaired function of the nuclear receptor NHR-25 abolishes differentiation of the neural T cell lineage similarly to mutations in Wnt/β-catenin asymmetry signaling pathwaycomponents. By means of genetic interactionwe demonstrate that NHR-25 cooperates with the Wnt/β-catenin pathway and with a parallel RUNX signaling to establish the correct fate of T cell daughters. Strikingly, the positive interaction between NHR-25 and Wnt/ catenin signaling in the T cell has an opposite character than in the C. elegans somatic gonad, where NHR-25 was shown to antagonize a β-catenin pathway.
