Fig. S1.
FOXA1/2 are expressed in adult mDA neurons but not in the DAergic neurons of the hypothalamus and in the enteric nervous system. Images show FOXA1/2 immunoreactivity in DAT-expressing mDA neurons (SNc) of control mice, and their absence in DAT-expressing neurons of the arcuate nucleus (A12), of the zona incerta (A13), of the hypothalamus (A14–A15), and of the olfactory bulbs (A16) (A). Image in B shows absence of FOXA1/2 immunoreactivity in neurons of the enteric nervous system, identified by PGP9.5 expression. mt, mammillothalamic tract; 3V, third ventricle. (Scale bars: 100 μm.)
