ProteomicsSynaptosome proteomics of tetanus neurotoxin-injected mice
Network hyperexcitability is manifested as frequent ictal discharges, often caused by unbalanced neurotransmission. We assessed synaptic changes in the hyperexcitable visual cortex of tetanus neurotoxin-injected mice (TeNT). A proteomics analysis of synaptic content revealed Carboxypeptidase E (CPE)...

Neuron derived exosomes have been enriched from plasma using L1CAM antigen. Vesicles were enriched from plasma of Parkinson Disease patients and controls. The NDE morphology was observed by transmission electron microscope (TEM). miRNA-155 content was studied both in PD-NDE and control-NDE. LC-MS/MS...

ProteomicsUltraviolet Photodissociation of ESI and MALDI generated protein ions on a Q-Exactive mass spectrometer
UVPD was implemented on an Orbitrap Q-Exactive plus equipped with a ESI/EP-MALDI. UVPD of MALDI generated ions was benchmarked against MALDI-ISD, MALDI-HCD and ESI-UVPD. MALDI UVPD outperformed MALDI HCD and ISD efficiently sequencing small proteins ions.

ProteomicsNovel PPT+SEC Workflow for High-Sensitivity Extracellular Vesicle Proteomics from Cell Media
Size exclusion chromatography (SEC) is a well-established method for the isolation of extracellular vesicles (EVs), but the large elution volumes necessitate a concentration step prior to proteomics analysis. This concentration step can lead to significant EV loss. Here we report an EV proteomics ap...

ProteomicsInvestigation of region specific lipid alterations in symptomatic atherosclerotic plaques using mass spectrometry imaging
Atherosclerotic plaques are composed by different cell populations that interact one with each other in a complex and heterogeneous environment. Here we report a MALDI mass spectrometry imaging investigation of the lipid profile of specific plaque regions, to discriminate between symptomatic and asy...

MetabolomicsAssessing the potential of sputtered gold nanolayers in mass spectrometry imaging for metabolomics applications (Brain MALDI-MSI assay)

Mass spectrometry imaging (MSI) is a molecular imaging technique that maps the distribution of molecules in biological tissues with high spatial resolution. The most widely used MSI modality is matrix-assisted laser desorption/ionization (MALDI), mainly due to the large variety of analyte classes...
