De novo loss of function mutations in the ubiquitin ligase-encoding gene Cullin3 (CUL3) lead to autism spectrum disorder (ASD). In mouse, constitutive Cul3 haploinsufficiency leads to motor coordination deficits as well as ASD-relevant social and cognitive impairments. However, induction of Cul3 haploinsufficiency later in life does not lead to ASD-relevant behaviors, pointing to an important role of Cul3 during a critical developmental window. Here we show that Cul3 is essential to regulate neu ...[more]

General anaesthesia leads to phosphoproteome changes in proteins involved in cytoskeleton remodelling and synaptic processes in the supraoptic nucleus of the hypothalamus

Project description:Despite the widespread use of general anaesthetics, the mechanisms mediating their effects are still not understood. Although suppressed in most parts of the brain, neuronal activity, as measured by FOS activation, is increased in the hypothalamic supraoptic nucleus (SON) by numerous general anaesthetics, and evidence points to this brain region being involved in the induction of general anaesthesia and natural sleep. Posttranslational modifications of proteins, including changes in phosphorylation, enable fast modulation of protein function which could be underlying the rapid effects of general anaesthesia. In order to identify potential phosphorylation events in the brain mediating general anaesthesia effects, we have explored the phosphoproteome responses in the rat SON, and compared these to cingulate cortex (CC) which displays no FOS activation is response to general anaesthetics. We found many changes in the phosphoproteomes of both the CC and SON in response to 15 minutes of isoflurane exposure. Pathway analysis indicated that proteins undergoing phosphorylation adaptations are involved in cytoskeleton remodelling and synaptic signalling events. Importantly, changes in protein phosphorylation appeared to be brain region-specific suggesting that differential phosphorylation adaptations might underlie the different neuronal activity responses to general anaesthesia between the CC and SON. In summary, these data suggest that rapid posttranslational modifications in proteins involved in cytoskeleton remodelling and synaptic signalling events might mediate the central mechanisms mediating general anaesthesia.

Molecular identification of a BAR domain-containing coat complex for endosomal recycling of transmembrane proteins

Project description:Protein trafficking requires coat complexes that couple recognition of sorting motifs in transmembrane cargos with biogenesis of transport carriers. The mechanisms of cargo transport through the endosomal network are poorly understood. Here, we identify a sorting motif for endosomal recycling of cargos including the cation-independent mannose-6-phosphate receptor and semaphorin 4C by the membrane tubulating BAR domain-containing sorting nexins SNX5 and SNX6. Crystal structures establish that this motif folds into a β-hairpin that binds a site in the SNX5/SNX6 phox homology domains. Over sixty cargos share this motif and require SNX5/SNX6 for their recycling. These include cargos involved in neuronal migration and a Drosophila snx6 mutant displays defects in axonal guidance. These studies identify a sorting motif and provide molecular insight into an evolutionary conserved coat complex, the ‘Endosomal SNX-BAR sorting complex for promoting exit 1’ (ESCPE-1), which couples sorting motif recognition to BAR domain-mediated biogenesis of cargo-enriched tubulo-vesicular transport carriers.

Placental macrophage (Hofbauer cell) response to viral and bacterial ligands is influenced by fetal sex

Project description:Bacterial and viral infections of the placenta are associated with inflammation and adverse pregnancy outcomes. Hofbauer cells (HBCs) are specialised fetal-origin macrophages in the placental villi and are proposed to protect the fetus from vertical transmission of pathogens; however, they are poorly understood. Here, we have performed quantitative proteomics on term HBCs under resting conditions and following exposure to bacterial and viral pathogen associated molecular patterns (PAMPs), and investigated the contribution of fetal sex to these responses. Resting HBCs expressed a plethora of proteins pertinent to macrophage function, including chemokines, cytokines, Toll-like receptors, and classical and non-classical major histocompatibility complex class I and II molecules. HBCs mounted divergent responses to bacterial versus viral PAMPs but exhibited protein expression changes suggestive of a switch towards a more pro-inflammatory phenotype. A comparison between male and female HBCs, showed that the latter mounted a much stronger and wider response. Sexual dimorphism in HBCs was primarily associated with lipid metabolism in males and cytoskeleton organisation in females. We provide a novel and comprehensive understanding regarding the phenotype of term placental macrophages and their sex-dependent responses to infectious triggers.

Enhancement of red blood cell transfusion compatibility using CRISPR-mediated erythroblast gene editing

Project description:Regular blood transfusion is the cornerstone of care for patients with red blood cell (RBC) disorders such as thalassemia or sickle cell disease. With repeated transfusion, alloimmunisation often occurs due to incompatibility at the level of minor blood group antigens. We use CRISPR-mediated genome editing of an immortalised human erythroblast cell line (BEL-A) to generate multiple enucleation competent cell lines deficient in individual blood groups. Edits are combined to generate a single cell line deficient in multiple antigens responsible for the most common transfusion incompatibilities: ABO (Bombay phenotype), Rh (Rhnull), Kell (K0), Duffy (Duffynull), GPB (S- s- U-). These cells can be differentiated to generate deformable reticulocytes, illustrating the capacity for coexistence of multiple rare blood group antigen null phenotypes. This study provides the first proof-of-principle demonstration of combinatorial CRISPR-mediated blood group gene editing to generate customisable or multi-compatible RBCs for diagnostic reagents or recipients with complicated matching requirements.

Characterisation of proteome of a novel Escherichia coli strain exhibiting mucoviscous phenotype.

Project description:Protein expression by E. coli 26561 during the late-exponential phase of cultures under anaerobic conditions was examined. E. coli 26561 is a multidrug resistant (MDR) and shows an unusual hyper-mucoviscous phenotype. Resistance includes ESBL (CTX-M-14) and proteome was determined with and without exposure to sub-MIC concentrations of the 3rd generation cephalosporin ceftazidime. Ceftazidime exposure was at two sub-MIC levels, specifically 0.25x MIC (samples 5-7), 0.5x MIC (samples 8 - 10); samples 1-4 provided the unexposed Control. Both whole and phospho-enriched fractions for each sample were analysed. Quantification of peptides was assessed using 10-plex TMT labelling in conjunction with an Orbitrap Fusion Tribrid. Raw data produced by the Orbitrap were processed using Max Quant 1.5.4.7 using the included Andromeda search engine. Peptides were searched against our own database of E. coli 26561 proteins which was produced from a hybrid assembly of our reads obtained from MiSeq and PacBio sequencing platforms.

Multiomic Approach Characterises the Neuroprotective Role of Retromer in Regulating Lysosomal Health

Project description:Retromer controls cellular homeostasis through regulating integral membrane protein sorting and transport and by controlling late-stage maturation of the endo-lysosomal network. Retromer dysfunction, which is linked to neurodegenerative disorders including Parkinson’s and Alzheimer’s diseases, manifests in complex cellular phenotypes, though the precise nature of this dysfunction, and its relation to neurodegeneration, remain unclear. Here, we perform the first integrated multiomics approach to provide precise insight into the impact of Retromer dysfunction on endo-lysosomal health and homeostasis within a human neuroglioma cell model. We quantify profound changes to the lysosomal proteome, indicative of broad lysosomal dysfunction and inefficient autophagic lysosome reformation, coupled with a reconfigured cell surface proteome and secretome reflective of increased lysosomal exocytosis. Through this global proteomic approach and parallel transcriptomic analysis, we provide an unprecedented integrated view of Retromer function in regulating lysosomal homeostasis and emphasise its role in neuroprotection.
