Proteome of mouse striatal dopamine synaptosomes purified by fluorescence sorting

ABSTRACT: Dopamine transmission is a monoaminergic system involved in reward processing and motor control. Volume transmission is thought to be the main mechanism by which monoamines modulate effector transmission though synaptic structures are scarcely described. In the present work we aimed to unravel the cellular and molecular synaptome of single projection pathways (Zhu F, Cizeron M, Qiu Z, Benavides-Piccione R, Kopanitsa MV, Skene NG, Koniaris B, DeFelipe J, Fransén E, Komiyama NH & Grant SGN (2018) Architecture of the Mouse Brain Synaptome. Neuron 99: 781–799.e10). To that end, we established a workflow combining fluorescence tracing of the dopaminergic pathway, fluorescence activated synaptosome sorting and mass spectrometry-based proteomics. With this approach we provide the first ex-vivo model to thoroughly analyse the cellular and molecular organisation of dopaminergic synapses from mouse striatum.

Synthesis of flavonol-bearing probes and chemical proteomic analysis of Asteraceae petals in search of flavonoid enzymes

Project description:In flowers of Asteraceae, yellow flavonols bearing an additional hydroxyl group at positions 6 or 8 (ring A) contribute to petal UV-absorbing pigmentation patterns, which play a crucial role in attracting pollinating insects. Understanding the biogenesis of these special flavonols requires the identification of any specific enzyme involved in these incorporations of extra hydroxyl groups on the quercetin ring A. To this aim, flavonol-bearing biotinylated probes have been designed and synthesized to explore their ability to selectively capture target proteins or biosynthetic enzymes under oxidative activation. These probes demonstrate the ability to capture several flavonoid enzymes from Rudbeckia and Tagetes microsomes and allow the identification of uncharacterized candidates for novel flavonoid enzymes.

Proteomic analysis of the entorhinal cortex and CA1 subfields of the hippocampus of macaques injected with tau seeds from Alzheimer’s brain

Project description:The "prion-like" features of Alzheimer’s disease (AD) tauopathy and its relationship with amyloid β (Aβ) has never been experimentally studied in primates phylogenetically close to humans. We injected 17 macaques in the entorhinal cortex with nanograms of tau proteopathic seeds purified from AD brains or control extracts from aged-matched healthy brains, with or without intracerebroventricular co-injections of recombinant Aβ oligomers. After neuropathological examination of the macaque’s brain, we also performed mass spectrometry-based proteomics of macaques’ entorhinal cortex and CA1 to study the spatial response (local and distant) to tau seeds injections (and its modulation by oligomeric Aβ).

Critical role of Aquaporin-1 and telocytes in infantile hemangioma response to propranolol beta-blockade

Project description:Propranolol, a non-selective β-adrenergic receptor (ADRB) antagonist, is the first-line therapy for severe infantile hemangiomas (IH). Since the incidental discovery of propranolol efficacy in IH, preclinical and clinical investigations have shown evidence of adjuvant propranolol response in some malignant tumors. However, the mechanism for propranolol antitumor effect is still largely unknown, owing to the absence of a tumor model responsive to propranolol at non-toxic concentrations. Immunodeficient mice engrafted with different human tumor cell lines were treated with anti-VEGF bevacizumab, to create a model sensitive to propranolol. Proteomics analysis was used to reveal propranolol-mediated protein alteration correlating with tumor growth inhibition and Aquaporin-1 (AQP1), a water channel modulated in tumor cell migration and invasion, was identified. IH tissues and cells were then functionally investigated. Our functional protein association networks analysis and knockdown of ADRB2 and AQP1 indicated that propranolol treatment and AQP1 downregulation trigger the same pathway, suggesting that AQP1 is a major driver of betablockers antitumor response. Examining AQP1 in human hemangioma samples, we found it exclusively in a perivascular layer, so far unrecognized in IH, made of telocytes (TC). Functional in vitro studies showed that AQP1-positive telocytes play a critical role in IH response to propranolol and that modulation of AQP1 in IH-TC by propranolol or shAQP1 decreases capillary-like tube formation in a Matrigel based angiogenesis assay. We conclude that IH sensitivity to propranolol may rely at least in part to a cross talk between lesional vascular cells and stromal telocytes.

Synaptic transmission induces site specific changes in sialylation on N-linked glycoproteins in nerve terminals

Project description:Synaptic transmission is an ultra-fast process that aims at transducing a signal from one neuron to another neuron or cell by the release of neurotransmitters. This process requires rapid response which can be transmitted through fast molecular switches such as post-translational modifications of proteins. We aimed at investigating the potential importance in dynamic modulation of sialic acids on N-linked glycoproteins that are essential for the synaptic transmission process. For this, we characterize site-specific alteration in sialylated N-linked glycosylation in the active zone of rat nerve terminals (synaptosomes) after depolarization by using quantitative sialiomics.

The Obesity-associated Fto gene regulates activity of the dopaminergic midbrain circuitry [FTO KO]

Project description:Here we use MeRIP-Seq to analyze global adenosine methylation (m6A) in mRNAs in the midbrain and striatum of Fto-deficient mice. We find that Fto deficiency leads to increased methylation within a subset of mRNAs important for neuronal signaling, including many within the dopaminergic signaling pathway. Collectively, our results show that Fto regulates demethylation of specific mRNAs in vivo, and this activity relates to control of dopaminergic transmission.

Dopamine transporter and synaptic vesicle sorting defects underlie auxilin-associated Parkinson’s disease

Project description:Auxilin participates in the uncoating of clathrin-coated vesicles (CCVs), thereby facilitating synaptic vesicle (SV) regeneration at presynaptic sites. Auxilin (DNAJC6/PARK19) loss-of-function mutations cause early-onset Parkinson’s disease (PD). Here, we utilized auxilin-knockout (KO) mice to elucidate the mechanisms through which auxilin deficiency and clathrin-uncoating deficits lead to PD. Auxilin KO mice display cardinal features of PD, including progressive motor deficits, α-synuclein pathology, nigral dopaminergic loss, and neuroinflammation. Significantly, treatment with L-DOPA ameliorated motor deficits. Unbiased proteomic and neurochemical analyses of auxilin KO brains indicated dopamine dys-homeostasis. We validated these findings by demonstrating slower dopamine reuptake kinetics in vivo, an effect associated with dopamine transporter misrouting into axonal membrane deformities in the dorsal striatum. Defective SV protein sorting and elevated synaptic autophagy also contribute to ineffective dopamine sequestration and compartmentalization, ultimately leading to neurodegeneration. This study advances our knowledge of how presynaptic endocytosis deficits lead to dopaminergic vulnerability and pathogenesis of PD.
