Lactate promotes plasticity gene expression by potentiating NMDA signaling in neurons

Pierre Magistretti, Pascal Jourdain, Igor Allaman, Gabriele Grenningloh, Evelyne Ruchti, Jiangyan Yang

L-lactate is a product of aerobic glycolysis that can be used by neurons as an energy substrate. Here we report that in neurons L-lactate stimulates the expression of synaptic plasticity-related genes such as Arc, c-Fos, and Zif268 through a mechanism invo ...

Miniature neurotransmission is required to maintain Drosophila synaptic structures during ageing

Olivier Burri, Evelyne Ruchti, Brian Donal McCabe, Wei Jiao, Soumya Banerjee, Samuel William Vernon

The decline of neuronal synapses is an established feature of ageing accompanied by the diminishment of neuronal function, and in the motor system at least, a reduction of behavioural capacity. Here, we have investigated Drosophila motor neuron synaptic te ...

The matricellular protein Drosophila Cellular Communication Network Factor is required for synaptic transmission and female fertility

Evelyne Ruchti, Brian Donal McCabe

Within the extracellular matrix, matricellular proteins are dynamically expressed nonstructural proteins that interact with cell surface receptors, growth factors, and proteases, as well as with structural matrix proteins. The cellular communication networ ...

Intact Drosophila central nervous system cellular quantitation reveals sexual dimorphism

Kathryn Hess Bellwald, Evelyne Ruchti, Ying Shi, Brian Donal McCabe, Wei Jiao, Soumya Banerjee, Gard Spreemann, Samuel William Vernon

Establishing with precision the quantity and identity of the cell types of the brain is a prerequisite for a detailed compendium of gene and protein expression in the central nervous system (CNS). Currently, however, strict quantitation of cell numbers has ...

A conditional glutamatergic synaptic vesicle marker for Drosophila

Evelyne Ruchti, Brian Donal McCabe

Glutamate is a principal neurotransmitter used extensively by the nervous systems of all vertebrate and invertebrate animals. It is primarily an excitatory neurotransmitter that has been implicated in nervous system development, as well as a myriad of brai ...

Trio preserves motor synapses and prolongs motor ability during aging

Evelyne Ruchti, Marine Van Campenhoudt, Greta Limoni, Brian Donal McCabe, Wei Jiao, Soumya Banerjee, Samuel William Vernon

The decline of motor ability is a hallmark feature of aging and is accompanied by degeneration of motor synaptic terminals. Consistent with this, Drosophila motor synapses undergo characteristic age -dependent structural fragmentation co -incident with dim ...

Retromer deficiency in Tauopathy models enhances the truncation and toxicity of Tau

Graham Knott, Evelyne Ruchti, Catherine Maclachlan, Greta Limoni, Brian Donal McCabe, Wei Jiao

Alteration of the levels, localization or post-translational processing of the microtubule associated protein Tau is associated with many neurodegenerative disorders. Here we develop adult-onset models for human Tau (hTau) toxicity in Drosophila that enabl ...

CERT1 mutations perturb human development by disrupting sphingolipid homeostasis

Paolo De Los Rios, Bruno Lemaitre, Evelyne Ruchti, Sylvia Ho, Anthony Vocat, Marine Van Campenhoudt, Samuel Rommelaere, Greta Limoni, Stefano Zamuner, Giovanni D'Angelo, Laura Capolupo, Charlotte Julie Caroline Gehin, Samuel Sagar Kumar, Huixin Guo

Neural differentiation, synaptic transmission, and action potential propagation depend on membrane sphingolipids, whose metabolism is tightly regulated. Mutations in the ceramide transporter CERT (CERT1), which is involved in sphingolipid biosynthesis, are ...
