The presynaptic protein bassoon organizes synaptic vesicles into functional pools at glutamatergic synapses via regulation of presynaptic phosphorylation and cAMP homeostasis. This study further reveals that a CDK5/PDE4/cAMP axis controls neurotransmitter release.
New paper is online
Burcu joined lab several weeks ago to work on the role of CtBP1 in neurodevelopment.
This Monday, Lena defended her thesis. Well done, Lena! Congratulations and all the best for all your future projects!
We are pleased to announce a release of nice study led by our collaborator Prof. Christian Müller. It was pleasure to contribute, thanks Christian!
Neutral sphingomyelinase mediates the co-morbidity trias of alcohol abuse, major depression and bone defects
Neutral sphingomyelinase (NSM) and its coding gene SMPD3 is a single source for multiple pathways interlinking alcohol abuse—depression/anxiety—bone disorder (DH dorsal hippocampus, Nac nucleus accumbens).
On Monday, Debarpan defended his PhD. Congratulations. You did a great job and we are delighted to have you in the team!
Congratulation, Dr. Debarpan!
Our study about regulation of synaptic vesicle recycling at excitatory synapses by Amyloid beta and alpha7 nicotinic acetylcholine receptors is online.
Anni et al., (2021) demonstrated that Aβ1-42 and Aβ1-16, but not Aβ17-42, increased size of the recycling pool of synaptic vesicles (SV). This presynaptic effect was driven by enhancement of endogenous cholinergic signalling via α7 nicotinic acetylcholine receptors, which led to activation of calcineurin, dephosphorylation of synapsin 1 and consequently resulted in reorganization of functional pools of SV increasing their availability for sustained neurotransmission. These results identify synapsin 1 as a molecular target of Aβ and reveal an effect of physiological concentrations of Aβ on cholinergic modulation of glutamatergic neurotransmission.
Congratulations Dani and thanks to the whole team!
We discussed this topic extensively at our symposium at the
in the symposium 14th meeting of German neuroscience society . S26 Regulation of synaptic vesicle recycling: from physiology to disease
Yesterday, after the work, we took our backpacks and climbed over the hill to look over town of Erlangen. Then we spent nice evening in the beer-garden in Atzelsberg.
Today Daniela defended her thesis. Congratulations, Dani! You did a great job!
Daniela explaining her work.
Under the mask there is a wide smile 😃!
Zoicas et all described new mouse model of depression where acid sphyngomyelinase (Smpd1) was overexpressed exclusively in the forebrain. Thanks for nice collaboration Iulia and Cosima!
