Analysis of proteins proximal to epsin 1 in A549 cells during entry of influenza A virus

ABSTRACT: Influenza A viruses (IAVs) are respiratory pathogens that represent a global concern due to their ability to cause seasonal epidemics and sporadic pandemics in the human population. Thus, a comprehensive understanding of IAV biology is essential in order to design effective antivirals. It is well established that entry of most IAVs begins through binding to cell surface sialic acid, however the identity of receptors that mediate virus internalization remains unclear. Here, we performed TurboID-based proximity labelling centered on epsin 1, a protein required for clathrin-mediated endocytosis of IAV, to uncover internalization receptors. By performing affinity-based purification of biotinylated proteins coupled to mass spectrometry, we identified 34 proteins proximal to epsin 1 during IAV infection. Therein we found 11 high-confidence STRING interactors for epsin 1 and 3 putative pro-viral host factors for IAV infection, validating our approach.

TRIM16 overexpression in HEK293T cells results in cell line-specific antiviral activity

Project description:In this paper we investigate one of the lesser studied TRIM family proteins, TRIM16, to determine if it might impact the ability of different viruses to replicate productively in host cells. TRIM16 is unique compared to other TRIM proteins in that it mediates E3 ligase activity despite lacking the catalytic RING domain present in other TRIM proteins. TRIM16 has been shown to play a role in innate immunity by increasing the secretion proinflammatory cytokine Il-1 in macrophages through interactions with components of the inflammasome complex (procaspase-1 and NALP-1). TRIM16 also mediates ubiquitination and aggregation of misfolded proteins which are subsequently degraded through the autophagic pathway in cells under proteotoxic and oxidative stress11. It does so through interactions with the p62-KEAP-NRF2 complex and stabilization of the NRF2 protein through multiple mechanisms11. Interestingly the NRF2 protein has been implicated in antiviral immunity, as previous studies have shown that infection of NRF2 (-/-) mice with respiratory syncytial virus (RSV) resulted in significantly higher viral titres in the lungs compared to NRF2 (+/+) mice. In addition to these clues in the literature, a recent study from our group examining transcriptional signatures in type II airway epithelial cells (AEC II) isolated from mock versus IAV-infected mice indicated that TRIM16 was upregulated in AECII following IAV infection in vivo.

Endogenous interactomes of MFN1 and MFN2 provide novel insights into interorganelle communication and autophagy

Project description:Mitofusin-1 (MFN1) and Mitofusin-2 (MFN2) are key players in mitochondrial fusion, endoplasmic reticulum (ER)-mitochondria yuxtaposition, and autophagy. However, the mechanisms by which these proteins participate in these processes remain poorly understood. To better understand their functions, we studied the interactomes of these two proteins. To this end, we used CRISPR/Cas9 technology to insert an HA-tag in the C-terminal domain of MFN1 and MFN2 and generated HeLa cell lines that endogenously expressed MFN1-HA or MFN2-HA, respectively. HA-pulldown followed by mass spectrometry identified potential interactors of MFN1 and MFN2. A substantial proportion of interactors were common for MFN1 and MFN2 and were regulated by nutrient deprivation. We validated novel ER and endosomal partners of MFN1 and/or MFN2 with a potential role in interorganelle communication. We characterized RAB5C as an endosomal modulator of mitochondrial dynamics through its interaction with MFN1 and SLC27A2 as a novel partner of MFN2 relevant in autophagy. Our findings reveal that MFN proteins participate in nutrient-modulated pathways involved in organelle communication.

Disruption of mitochondrial dynamics triggers muscle inflammation through interorganellar contacts and mtDNA mislocation

Project description:Some forms of mitochondrial dysfunction induce sterile inflammation through mitochondrial DNA (mtDNA) recognition by intracellular DNA sensors. However, the involvement of mitochondrial dynamics mitigating such processes and their impact on muscle fitness remain unaddressed. Here we report that opposite mitochondrial morphologies induce distinct inflammatory signatures, caused by differential activation of DNA sensors TLR9 or cGAS. In the context of mitochondrial fragmentation, we demonstrate that mitochondria-endosome contacts mediated by the endosomal protein Rab5C are required in TLR9 activation in cells. Skeletal muscle mitochondrial fragmentation promotes TLR9-dependent inflammation, muscle atrophy, reduced physical performance and enhanced IL6 response to exercise, which improved upon chronic anti-inflammatory treatment. Taken together, our data demonstrate that mitochondrial dynamics is key in preventing sterile inflammatory responses, which precede the development of muscle atrophy and impaired physical performance. Thus, we propose the targeting of mitochondrial dynamics as an approach to treating disorders characterized by chronic inflammation and mitochondrial dysfunction.

Characterization of Protein Precipitation Methods of Clinical Samples for Simple and Low-Cost Methods to Enhance the Depth and Breadth of Plasma Proteomics

Project description:Plasma is an abundant source of proteins and potential biomarkers to aid in the detection, diagnosis, and prognosis of human diseases. These proteins are often present at low levels in the blood and difficult to identify and measure due to the large dynamic range. Abundant protein precipitation with perchloric acid (PerCA) can increase protein identifications and depth of plasma proteomic studies. The goal of this work was to characterize and compare various protein precipitation methods related to plasma proteomic depth and breadth. Three acid- and four solvent-based precipitation methods were evaluated. All methods tested provided excellent plasma proteomic coverage (>600 identified protein groups) and detected protein in the low pg/ml range. Functional enrichment analysis revealed subtle differences within and larger changes between the precipitant groups. Methanol-based precipitation outperformed the other methods based on identifications and reproducibility. The methods’ performance was verified using eight lung cancer patient samples, where >700 protein groups were measured and proteins with an estimated plasma concentration of ~10 pg/ml were detected. Various protein precipitation agents are amenable to extending the depth and breadth of plasma proteomes. These data can guide investigators to implement inexpensive, high-throughput methods for their plasma proteomic workflows.

Development and validation of an ELISA to measure REG3E in canine blood

Project description:Regenerating islet-derived proteins (REG) are upregulated in people with sepsis, pancreatitis, and gastrointestinal diseases. One member of the REG family, namely REG3E, was recently identified in pancreatic tissue and plasma of dogs, with high expression in pancreatitis and sepsis. Our objective was to develop and validate an ELISA to measure REG3E concentrations in canine blood. An indirect sandwich ELISA was successfully developed using recombinant canine REG3E protein and polyclonal anti-canine REG3E antibodies raised in guinea pigs and rabbits. Antibody specificity was assessed using Western blot and mass spectrometric analysis of protein purified from canine plasma using Protein A Sepharose High Performance SpinTrap columns.

Proteomic and lipidomic profiling of demyelinating lesions identifies fatty acids as modulators in inflammation resolution

Project description:After demyelinating injury of the central nervous system, resolution of the mounting acute innate inflammation is crucial for the initiation of a regenerative response. To identify factors in lesion recovery after demyelination injury, we used a toxin-induced model, in which a single dose of lysolecithin is injected into the corpus callosum to induce a focal demyelinating lesion. Afterwards, we investigated the proteome of demyelinating lesions at different time points post injection (dpi) in a time resolved manner. Lesion sites were excised analyzed from different mice at 0 dpi, without lysolecithin injection, as well as lysolecithin treated mice at 3 dpi, 7 dpi, and 14 dpi. Overall, immune cell migration, especially infiltration of microglia and macrophages, as well as fatty acid metabolism are playing crucial roles for the immidiate response, repair and finally lesion recovery. Additionally, Using lipidomics and eicosanoidomics, we identified bioactive lipids in the resolution phase of inflammation with a marked induction of n-3 polyunsaturated fatty acids. Using fat-1 transgenic mice, which convert n-6 fatty acids to n-3 fatty acids, we found that reduction of the n-6/n-3 ratio facilitates inflammation resolution. In addition, we observed accelerated inflammation resolution and enhanced generation of oligodendrocytes in aged mice when n-3 fatty acids are shuttled to the brain. Thus, n-3 fatty acids and eicosanoids, their oxidized bioactive products, enhance lesion recovery and may therefore provide the basis for novel pro-regenerative medicines of demyelinating diseases in the central nervous system.

Proximity proteomics reveals UCH-L1 as an essentialregulator of NLRP3-mediated IL-1β production in humanmacrophages and microglia

Project description:Activation of the NACHT, LRR family pyrin domain containing 3 (NLRP3) inflammasome complex is an essential innate immune signalling mechanism. To reveal how NLRP3 inflammasome assembly and activation are controlled, in particular by components of the ubiquitin system, proximity labelling, affinity purification and RNAi screening approaches were performed. Our study provides an intricate time-resolved molecular map of different phases of NLRP3 inflammasome activation. We discovered that ubiquitin C-terminal hydrolase 1 (UCH-L1) interacts with the NACHT domain of NLRP3, and downregulation of UCH-L1 decreases pro-IL-1β levels. UCH-L1 chemical inhibition with small molecules interfered with NLRP3 puncta formation and ASC oligomerisation, leading to altered IL-1β cleavage and secretion, particularly in microglia cells, which exhibited elevated UCH-L1 expression as compared to monocytes/macrophages. Altogether, we profiled NLRP3 inflammasome activation dynamics and highlight UCH-L1 as an important modulator of NLRP3-mediated IL-1β production, suggesting that a pharmacological inhibitor of UCH-L1 may decrease inflammation-associated pathologies.
