MetabolomicsMultiomics of synaptic junctions reveals altered lipid metabolism and signaling following environmental enrichment
Membrane lipids and their metabolism have key functions in neurotransmission. Here we provide a quantitative lipid inventory of mouse and rat synaptic junctions. To this end, we developed a multiomics extraction and analysis workflow to probe the interplay of proteins and lipids in synaptic signal t...

MetabolomicsDifferent regions of synaptic vesicle membrane regulate VAMP2 conformation for the SNARE assembly
Vesicle associated membrane protein 2 (VAMP2/synaptobrevin2), a core SNARE protein residing on synaptic vesicles (SVs), forms helix bundles with syntaxin-1 and SNAP25 for the SNARE assembly. Prior to the SNARE assembly, the structure of VAMP2 is unclear. Here, by using in-cell NMR spectroscopy, we d...

MetabolomicsGut Microbiota–Derived Ergothioneine Alleviates Antipsychotic-Induced Synaptic and Cognitive Impairments

Background: Chronic use of antipsychotic drugs is associated with neuronal damage and cognitive impairment, potentially mediated by alterations in gut microbiota metabolites, although the specific metabolite involved remains unknown.

Objective: To identify the key metabolite responsible for...

MetabolomicsFaecal microbiota transplant from aged donor mice affects spatial learning and memory via modulating hippocampal synaptic plasticity- and neurotransmission-related proteins in young recipients

BACKGROUND: The gut-brain axis and the intestinal microbiota are emerging as key players in health and disease. Shifts in intestinal microbiota composition affect a variety of systems, however, evidence of their direct impact on cognitive functions is still lacking. We tested whe...

MetabolomicsEssential omega-3 fatty acids tune microglial phagocytosis of synaptic elements in the developing brain

Omega-3 fatty acids (n-3 polyunsaturated fatty acids; n-3 PUFAs) are essential for the functional maturation of the brain. Westernization of dietary habits in both developed and developing countries is accompanied by a progressive reduction in dietary intake of n-3 PUFAs. Low maternal intake of n...

ProteomicsCross-linking mass spectrometry uncovers protein interactions and functional assemblies in synaptic vesicle membranes
Synaptic vesicles are storage organelles for neurotransmitters in the pre-synaptic cytosol. When an action potential arrives at the pre-synaptic terminal, they fuse with the pre-synaptic membrane and neurotransmitters are released. In this project, we set out to study the protein interactions formed...

TranscriptomicsTranscriptional dysregulation of synaptic genes in a human iPSC model of major mental disorders
Schizophrenia and other psychiatric disorders are postulated to be developmental disorders resulting from synapse dysfunction. How susceptibility genes for major mental disorders could lead to synaptic deficits in humans is not well-understood. Here we generated induced pluripotent stem cells (iPSCs...

Transcriptomicsp53 prevents neurodegeneration by regulating synaptic genes
DNA damage has been implicated in neurodegenerative disorders, including Alzheimer’s disease and other tauopathies, but the consequences of genotoxic stress to postmitotic neurons are poorly understood. Here we demonstrate that p53, a key mediator of the DNA damage response, plays a neuroprotective ...

TranscriptomicsThe miRNA pathway controls rapid changes in activity-dependent synaptic structure at the Drosophila melanogaster neuromuscular junction (RT-PCR)
It is widely accepted that long-term changes in synapse structure and function are mediated by rapid activity-dependent gene transcription and new protein synthesis. A growing amount of evidence suggests that the microRNA (miRNA) pathway plays an important role in coordinating these processes. Despi...
