During clathrin mediated endocytosis (CME), the concerted action of dynamin and its interacting partners drives membrane scission. Essential interactions occur between the proline/arginine-rich domain of dynamin (dynPRD) and the Src-homology domain 3 (SH3) of various proteins including amphiphysins. Here we show that multiple SH3 domains must bind simultaneously to dynPRD through three adjacent motifs for dynamin's efficient recruitment and function. First, we show that mutant dynamins modified ...[more]

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.

Label-free proteomics of immuno-purified SYP61-trans-Golgi Network compartment in control condition and upon sphingolipid acyl-chain length reduction by metazachlor.

Project description:The trans-Golgi Network (TGN) in plants is a main sorting hub for proteins and lipids. The lipid composition at the TGN is instrumental to the polar sorting of the auxin efflux carrier PIN2 from TGN to the apical membrane. Here, we immuno-purified the full and intact TGN using the TGN-resident syntaxin SYP61 to identify and quantify TGN-proteins which abundance at TGN is dependent on the acyl-chain length of very-long chain fatty acids-containing lipids such as sphingolipids.

A proteomic analysis of the surface attachment in Pseudomonas aeruginosa early as 20 minutes incubation.

Project description:The goal of the project is the study of molecular events occurring during the attachment phase, first step of the biofilms formation. Thanks to an original growth system developed in our laboratory, we were able to compare, for the first time, the protein content of P. aeruginosa immobilized for 20 minutes only to that of their planktonic counterparts.

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).

Proteome of mouse striatal dopamine synaptosomes purified by fluorescence sorting

Project description: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.

Dynamic profiling of the protein life cycle in response to pathogens (protein)

Project description:Protein expression is regulated by production and degradation of mRNAs and proteins, but their specific relationships remain unknown. We combine measurements of protein production and degradation and mRNA dynamics to build a quantitative genomic model of the differential regulation of gene expression in LPS stimulated mouse dendritic cells. Changes in mRNA abundance play a dominant role in determining most dynamic fold changes in protein levels. Conversely, the preexisting proteome of proteins performing basic cellular functions is remodeled primarily through changes in protein production or degradation, accounting for over half of the absolute change in protein molecules in the cell. Thus, the proteome is regulated by transcriptional induction of novel cellular functions and remodeling of preexisting functions through the protein life cycle. Mouse primary dendritic cells were treated with LPS or mock stimulus and profiled over a 12-hour time course. Cells were grown in M-labeled SILAC media, which was replaced with H-labeled SILAC media at time 0. Aliquots were taken at 0, 0.5, 1, 2, 3, 4, 5, 6, 9, and 12 hours post-stimulation and added to equal volumes of a master mix of unlabeled (L) cells for the purpose of normalization. RNA-Seq was performed at 0, 1, 2, 4, 6, 9, and 12 hours post-stimulation.

Adaptation to pH and pH signaling in the phytopathogenic fungus Botrytis cinerea

Project description:The grey mould fungus Botrytis cinerea is capable of developing on a wide variety of host plants and different organs that differ greatly in their pH values. The strategy developed by this necrotrophic fungus is partly based on the acidification of the plant tissues via the secretion of several organic acids including oxalic acid. That’s why B.cinerea is considered as an “acidic” fungus. However, we have previously shown that it is also capable of alkalinizing its ambient environment during sunflower cotyledons or bean leaves infection and that the alkalinization is achieved by amino acids catabolism and ammonia secretion ( Billon-grand et al, 2012). This capacity to modulate the surrounding pH reveals also an ability to regulate the expression and the secretion of an arsenal of enzymes in order to produce virulence factors in accordance with the ambient pH and enzymes requirement for optimal activity. Expression of pH-regulated genes is controlled by the highly conserved signaling pathway Pal/Pac that leads to activation of the zinc finger transcription factor PACC under neutral or alkaline conditions. Investigations of the role of this pH regulator in the infectious process of B.cinerea are presented.
