The transcription factor BCL11A defines distinct subsets of midbrain dopaminergic neurons. Tolve et al.

By combining intersectional labeling and viral-mediated tracing we demonstrate that Bcl11a-expressing mDA neurons form a highly specific subcircuit within the murine dopaminergic system. In the substantia nigra, the Bcl11a-expressing mDA subset is particularly vulnerable to neurodegeneration upon -synuclein overexpression or oxidative stress. Inactivation of Bcl11a in murine mDA neurons increases this susceptibility further, alters the distribution of mDA neurons and results in deficits in skilled motor behavior.

In summary, BCL11A defines mDA subpopulations with highly distinctive characteristics and is required for establishing and maintaining their normal physiology. Data description: each file contains raw data related to the indicated Figure of the Tolve et al. manuscript. Raw data are uncropped image files (.tif format) and/or excel tables with the quantifications that were used to create the graphs in the respective Figure.
