Article Synopsis
  • This chapter outlines an optimized protocol for isolating synaptic vesicles (SVs) from human induced pluripotent stem cell-derived neurospheres, beginning with the cultivation of mature neurons for functional studies.
  • The process involves isolating neurosphere-derived synaptosomes and enriching SVs through differential centrifugation.
  • Finally, the protocol utilizes nanoLC-MS/MS for proteomic analysis of SVs, aiding in the understanding of SV molecular diversity and neurotransmitter dynamics, with potential applications in neurological and neuropsychiatric research.

Article Synopsis
  • Glioblastoma (GBM) is the deadliest brain tumor in adults, and current therapies are largely ineffective, which drives the need for new treatment strategies based on the tumor's metabolic needs, specifically glucose and glutamine.
  • A ketogenic metabolic therapy (KMT) approach targets these metabolic pathways by combining dietary changes with specific drugs to limit glycolysis and glutaminolysis, while promoting the use of non-fermentable fuels like ketones and fatty acids.
  • The glucose-ketone index (GKI) serves as a biomarker to monitor treatment effectiveness, aiming to create a more hostile environment for tumor growth and improve outcomes in GBM as well as potentially other cancer types reliant on similar metabolic pathways.

The COVID-19 pandemic was initiated by the rapid spread of a SARS-CoV-2 strain. Though mainly classified as a respiratory disease, SARS-CoV-2 infects multiple tissues throughout the human body, leading to a wide range of symptoms in patients. To better understand how SARS-CoV-2 affects the proteome from cells with different ontologies, this work generated an infectome atlas of 9 cell models, including cells from brain, blood, digestive system, and adipocyte tissue.

Deciphering the molecular pathways associated with N-methyl-D-aspartate receptor (NMDAr) hypofunction and its interaction with antipsychotics is necessary to advance our understanding of the basis of schizophrenia, as well as our capacity to treat this disease. In this regard, the development of human brain-derived models that are amenable to studying the neurobiology of schizophrenia may contribute to filling the gaps left by the widely employed animal models. Here, we assessed the proteomic changes induced by the NMDA glutamate receptor antagonist MK-801 on human brain slice cultures obtained from adult donors submitted to respective neurosurgery.

The investigation of neurodegenerative diseases advanced significantly with the advent of cell-reprogramming technology, leading to the creation of new models of human illness. These models, derived from induced pluripotent stem cells (iPSCs), facilitate the study of sporadic as well as hereditary diseases and provide a comprehensive understanding of the molecular mechanisms involved with neurodegeneration. Through proteomics, a quantitative tool capable of identifying thousands of proteins from small sample volumes, researchers have attempted to identify disease mechanisms by detecting differentially expressed proteins and proteoforms in disease models, biofluids, and postmortem brain tissue.
