Meeting Summary

This workshop was convened by the National Institute of Neurological Disorders and Stroke for the purpose of reviewing the current status of proteomics, to engage scientists from various disciplines of proteomics and neuroscience in discussing issues to the study of the brain proteome, to identify the opportunities and requirements for the effective use of proteomics technologies in neuroscience research, and to determine the best proteomics tools and resources useful in the study of basic brain functions in normal and diseased states.

Proteomics is the systematic characterization of the complete set of proteins in a cell or tissue at a particular time. The levels of characterization may include various properties of the proteins such as its primary sequence, quantity, modification state, regulation, subcellular localization, structure, interaction partners and activity or cellular function that is performed in a large-scale fashion. Because of the immense datasets that can come from proteomic projects, robust bioinformatics and data management is a requisite for such studies. Proteomic approaches are useful in understanding the function of proteins, determining protein interaction partners (with other proteins, lipids, carbohydrates, metabolites), involvement in cellular pathways (such as signaling, metabolism, cell cycle, neuronal differentiation, apoptosis), profile changes through development and disease, for diagnosis and effects of treatment through monitoring of biomarkers and surrogate markers, and for target identification and drug discovery.

Proteomics is emerging as a powerful research tool in examining protein function, biochemical pathways and molecular networks. Separation-based approaches in proteomics may include high-resolution 2-D PAGE coupled with mass spectrometry (MS) and liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). On the other hand, nonseparation-based approaches may include direct MS in situ or the use of protein microarrays or other affinity-capture agents. Protein profiling can best be approached by differential isotope-labeling of test and control samples followed by MS. One of the major challenges for proteomic technologies is to increase the coverage of the proteome and have the capability to examine greater than 5000 proteins at a time. Being able to monitor post-translational modifications and to quickly ascertain where the proteins are inside the cell are also major challenges. Structural proteomics or the study of the 3-D structure of proteins by crystallography or NMR was not part of this workshop.

Neuroscience can benefit tremendously from the study of the proteome of the nervous system, and to be able to unravel its molecular organization and interactions, and cross talk between different cell types, various neurotransmitter receptors within the same synapse or across the synaptic cleft. This can be achieved at several different levels within the hierarchy of the nervous system which can be parsed with respect to the organization of the central and peripheral nervous systems, which by themselves can be further defined into various anatomical regions, such as cerebrum, cerebellum, hippocampus, and the local and distant circuits within those regions. Within those circuits are the various cell types (neurons, glia, oligodendrocytes) that may have their own subcellular compartments, synapses, axons and dendrites. This complex organization is flanked on one end by the phenotype and function, such as cognition, memory, learning, behavior, and on the other end by the molecules making up the genome, transcriptome, proteome and metabolonome that subsumes this organization and function.

The overall goal of the workshop was to critically assess the state and usefulness of proteomics as it applies to specific issues of the nervous system, and to identify areas where NINDS might play a role in facilitating the most effective use of proteomics in the neurosciences. The workshop addressed key issues regarding current and emerging technologies in proteomics, scientific and practical challenges germane to proteomics of the nervous system, integration and annotation of large protein databases, and how proteomic discoveries can be rapidly translated into prevention, treatment, and cures for neurological diseases. The following specific recommendations were made by the participants:

  • Recommendations for proteome analysis
    • Strategy
      • List of all brain proteins when technology permits
      • Functionally defined sets of proteins (e.g. apoptosis, signaling, GPCR, channels) as a good starting point
      • Subcellular compartments, e.g. synaptosome
      • Comparative analyses of model organisms
    • Resources
      • Access to appropriate platforms and training
      • Monoclonal antibody arrays
      • cDNA clones for expression into recombinant proteins
      • Tissue repositories
    • Technology innovations
      • Improved resolution and dynamic range
      • Isolation of individual cell types and subcellular fractionation, especially for low abundance proteins and membrane-bound proteins
      • Single cell proteomics
    • Neuroproteome alliance
      • Trans-NIH cooperation for common tasks
      • Promotion of centers and other collaborative efforts
      • International liaison and coordination of efforts
    • Recommendations for Databases
      • Central repository
      • Standards for data formatting to facilitate data comparison, exchange, verification and publication
      • Proteomic databases that will be interoperable with other databases, such as genomic and neuroscience-related databases, with interfaces to clinical information
