Description

The study reveals unexpected depletion of tyrosine hydroxylase-enriched astrocytes, microglia, and oligodendrocytes in PD, but provides no mechanistic explanation. Understanding why these non-neuronal cells express TH and become vulnerable could reveal novel therapeutic targets beyond dopaminergic neurons.
