Proteomic analysis of the 120k extracellular vesicles from Opisthorchis viverrini

ABSTRACT: The proteomic content of the extracellular vesicles (EVs) released by the liver fluke Opisthorchis viverrini has been addressed in the past. Here we employ a more comprehensive purification method of the 120k subpopulation of EVs and analyze proteins present in different locations of these EVs (including external trypsin-liberated peptides, cargo proteins and membrane proteins) using LC-MS/MS.

Proteomic analysis of two populations of Schistosoma mansoni-derived extracellular vesicles: exosome-like vesicles and microvesicles

Project description:Extracellular vesicles (EVs) have been characterized from many species of parasitic helminths, and recent experimental evidence supports important functions for their cargo in host-parasite relationships. Here, we carried out a detailed proteomic analysis of two populations of EVs – exosome like vesicles (ELVs) and microvesicles (MVs) – from Schistosoma mansoni. We profiled the proteins present in these EVs (including external trypsin-liberated peptides, cargo proteins, integral membrane proteins (IMPs) and peripheral membrane proteins (PMPs) using LC-MS/MS.

Peptidomics analysis of saliva of the two-spotted spider mite Tetranychus urticae

Project description:Recently, we elucidated T. urticae’s repertoire of secreted salivary proteins, revealing several members of expanded protein families with unknown functions [PMID: 27703040]. In this study, mite salivary secretions were additionally examined using a peptidomics approach.

Schistosoma haematobium proteomes

Project description:Despite the clear role of adult secreted and tegumental proteins as well as egg proteins in host-parasite interactions, there has not been any in-depth proteomic analysis of these or other Schistosoma haematobium proteomes. In the current project we have carried out the first comprehensive proteomic analysis of S. haematobium. The characterisation of the molecules playing a key role at the interphase between the host and the parasite is crucial for (i) a better understanding of the parasite’s biology and, (ii) for the development of new control and diagnostic approaches to tackle parasitic infections.

NanoString assays of miRNA in MCF7 and MCF10A cells and in extracellular vesicles (EVs) derived from these cells.

Project description:The goal of this study is to identify unique miRNA profiles of EVs from MCF7 and MCF10A cells that distinguish their cellular origin. 654 human mature miRNAs were analyzed in NanoString assays to identify miRNA with high abundance in MCF7 EVs and the greatest fold change for MCF7 EVs relative to MCF10A EVs.

Crosstalk between the effects of extracellular vesicles (Evs) and TNF on U937 human monocyte cell line

Project description:Under physiological conditions, extracellular vesicles (EVs) are present simultaneously in the extracellular compartment together with cytokines. Thus, we hypothesized that EVs in combination with cytokines induce different responses of monocyte cells compared to EVs or cytokines alone. Human monocyte U937 cells were incubated with EV-containing or EV-free CCRF human T-cell supernatant, with or without the addition of TNF. U937 cells cultured in EV-free supernatant, supernatant containing CCRF t-cell derived EVs, TNF or both. Each treatment option was measured in 3 replicates.

The surface proteome of extracellular vesicles from Fasciola hepatica

Project description:Helminth parasites secrete extracellular vesicles (EVs) as a means of exporting effector molecules into the host microenvironment. Once released, the parasite-derived EVs are internalised by host immune cells and trigger a range of biological effects including modulation of host immunity. While the molecular cargo of EVs have been characterised in many parasites, little is known about the surface-exposed molecules that may effect ligand-receptor interactions with the target host cell surface that initiate vesicle docking and subsequent internalisation. Here we used a membrane-impermeable biotin reagent to capture proteins displayed on the outer membrane surface of adult F. hepatica EVs and mass spectrometry to identified the surface proteins.

Surface proteome of large extracellular vesicles

Project description:The extracellular vesicle (EV) surface proteome (surfaceome) acts as a fundamental signalling gateway by bridging intra-and extracellular signalling networks, dictates EVs’ capacity to communicate and interact with its the/their environment, and is a source of potential disease biomarkers and therapeutic targets. However, our understanding of surface protein composition of large EVs (100-1000 nm), a major EV-subtype remains limited. Our study provides critical insights into proteins operating at the large interactive platform of L-EVs, and molecular leads for future studies seeking to decipher relatively-understudied L-EV form, heterogeneity and function.

Pratylenchus penetrans PME - Identification and characterization of the first pectin methylesterase gene discovered in the root lesion nematode Pratylenchus penetrans

Project description:Similar to other plant-parasitic nematodes, root lesion nematodes possess an array of enzymes that are involved in degradation of the plant cell wall. Here we report the identification of a gene encoding a cell wall degrading enzyme, pectin methylesterase PME (EC 3.1.1.11), in the root lesion nematode Pratylenchus penetrans. Both genomic and coding sequences of the gene were cloned for this species, showing the presence of four introns that excluded a potential bacterial contamination. Expression of the Pp-pme gene was localized in the esophageal glands of P. penetrans as determined by in situ hybridization. Temporal expression of Pp-pme in planta was validated for early time points of infection. The possible function and activity of the gene were assessed by transient expression of Pp-pme in N. benthamiana plants via a Potato virus X-based vector. To our knowledge, this is the first report on identification and characterization of a PME gene within the phylum Nematoda.

Role of miRNAs in acute kidney injury recovery induced by mesenchymal stromal cells and derived extracellular vesicles.

Project description:Phenotypic changes induced by extracellular vesicles (EVs) have been implicated in the recovery of acute kidney injury (AKI) induced by mesenchymal stromal cells (MSCs). miRNAs are potential candidates for cell reprogramming towards a pro-regenerative phenotype. The aim of the present study was to evaluate whether miRNA de-regulation inhibits the regenerative potential of MSCs and derived-EVs in a model of glycerol-induced AKI in SCID mice. For this purpose, we generated MSCs depleted of Drosha, a critical enzyme of miRNA maturation, to alter miRNA expression within MSCs and EVs. Drosha knock-down MSCs (MSC-Dsh) maintained the phenotype and differentiation capacity. They produced EVs that did not differ from those of wild type cells in quantity, surface molecule expression and internalization within renal tubular epithelial cells. However, EVs derived from MSC-Dsh (EV-Dsh) showed global down-regulation of miRNAs. Whereas, wild type MSCs and derived EVs were able to induce morphological and functional recovery in AKI, MSC-Dsh and EV-Dsh were ineffective. RNA sequencing analysis showed that genes deregulated in the kidney of AKI mice were restored by treatment with MSCs and EVs but not by MSC-Dsh and EV-Dsh. Gene Ontology analysis showed that down-regulated genes in AKI were associated with fatty acid metabolism. The up-regulated genes in AKI were involved in inflammation, ECM-receptor interaction and cell adhesion molecules. These alterations were reverted by treatment with wild type MSCs and EVs, but not by the Drosha counterparts. In conclusion, miRNA depletion in MSCs and EVs significantly reduced their intrinsic regenerative potential in AKI, suggesting a critical role of miRNAs. RNA-seq
