Adult Clock Neuron Somatic Neuropeptide Release and Cytonemes Regulate Sleep

The paper investigates how s-LNv clock neurons regulate sleep through neuropeptide release and cytoneme-mediated communication with l-LNv neurons.

Anticipatory Capture of Circulating Peptidergic Vesicles in a Clock Neuron

The paper shows that Drosophila clock neurons capture circulating neuropeptide vesicles in anticipation of release, independent of axonal expansion or calcium signaling.

Desynchronized Somas and Terminals in a Morning Clock Neuron: Presynaptic Ca2+ Spiking and Native Neuropeptide Release Peak As Somatic Ca2+ Declines

The paper investigates the timing mismatch between somatic Ca2+ activity and neuropeptide release in Drosophila sLNv neurons, finding that terminal Ca2+ spiking and neuropeptide release peak midmorning, hours before their behavioral effects.
