Expression of the appropriate repertoire of membrane channels, essential for activity of flight-promoting central dopaminergic neurons of Drosophila, requires store-operated Ca2+ entry during late pupal development and early adults.
Repressing astroglial PTBP1 by shRNA or antisense oligonucleotide fails to convert astrocyte to neuron including dopaminergic neuron in a 6-OHDA mouse model of PD.

Pedunculopontine neurons can evoke burst spiking in substantia nigra dopaminergic neurons without engaging a subtype of glutamate receptor previously thought to be necessary for this spiking mode.
Motivation for flight and feeding behaviour requires dopamine release which depends on cholinergic stimulation and intracellular Ca2+ release from ER stores in one or two pairs of central dopaminergic neurons.
The non-selective Na+ leak channel (NALCN) and the transient receptor potential 3 channel (TRPC3) cooperate in driving pacemaking in substantia nigra dopaminergic neurons.
Constitutive activation of an innate immunity response in mouse brain causes degeneration of dopaminergic neurons, suggesting novel targets for potentially neuroprotective strategies.

Promoting a Warburg-like shift in astrocytic metabolism through reduced mitochondrial electron transport accommodates the energetic burden caused by brain trauma without overwhelming cellular respiration and redox to salvage dopaminergic neurons.
