Organisms possess an endogenous molecular clock which enables them to adapt to environmental rhythms and to synchronize their metabolism and behavior accordingly. Circadian rhythms govern daily oscillations in numerous physiological processes, and the underlying molecular components have been extensively described from fruit flies to mammals. Drosophila larvae have relatively simple nervous...

Single cell transcriptome atlas of the Drosophila larval brain

Brunet Avalos, Clarisse ; Maier, G. Larisa ; Bruggmann, Rémy ; Sprecher, Simon G.

In: eLife, 2019, vol. 8, p. e50354

Cell diversity of the brain and how it is affected by starvation, remains largely unknown. Here, we introduce a single cell transcriptome atlas of the entire Drosophila first instar larval brain. We first assigned cell-type identity based on known marker genes, distinguishing five major groups: neural progenitors, differentiated neurons, glia, undifferentiated neurons and non-neural cells....

Regulation of TRPM8 channel activity by Src-mediated tyrosine phosphorylation

Manolache, Alexandra ; Selescu, Tudor ; Maier, G. Larisa ; Mentel, Mihaela ; Ionescu, Aura Elena ; Neacsu, Cristian ; Babes, Alexandru ; Szedlacsek, Stefan Eugen

The transient receptor potential melastatin type 8 (TRPM8) receptor channel is expressed in primary afferent neurons where it is the main transducer of innocuous cold temperatures and also in a variety of tumors, where it is involved in progression and metastasis. Modulation of this channel by intracellular signaling pathways has therefore important clinical implications. We investigated the...
