Status of IRD Development Centers of Excellence for Influenza Research and Surveillance 6th Annual Meeting Aug 1, 2012
Session Topics • Current CEIRS data in IRD • Surveillance • Serology • Immunology & ImmPort • IRD enhancements over past year • Search improvements • Surveillance data from map • Support for serology data • 3D movies • Phylogenetic tree decoration • Metadata-driven comparative genomics analysis • Sequence feature submission tool • Host factor data • Publications • Plans for future development
CEIRS Surveillance Samples 94% avian 5.8% non-human mam. 0.2% human
Surveillance Sample Stats *as of May 1, 2012
Introduction to ImmPort • Immunology Database and Analysis Portal (ImmPort) • Bioinformatics Integration Support Contract (BISC) • Purpose • Warehouse for storing immunology experiment data • Integrate data with analysis and visualization tools • Provide access to research community • Projects • Population Genetics Analysis Program • HLA Region Genetics in Immune-mediated Diseases • Modeling Immunity for Biodefense • Others
Additional ImmPort Capabilities • Integrate data from multiple resources • OMIM, GO, synonyms, protein-protein interactions, etc. • Suite of data analysis and visualization tools • Microarray • Flow Cytometry • Other “-omics” platforms
Phylogenetic Tree Decoration Decorate by: • Host species • Avian: Avian grouped/separated • Country • Year • HA subtype • NA subtype • HA & NA subtype • Geographic region • Flu season • SFVT Manual decoration
User Support and Outreach • Data • Evaluate feasibility of supporting Antigenic Cartography • Prepare packages of (correctly-formatted) data to export to external tools • Outreach • Perform on-site outreach at CEIRS centers • Continue developing tutorials for existing tools & features
Search • Query Capabilities • Ability to search for high-path and/or low-path strains (using sequence biomarkers)
Comparative Genomics • Develop PCR Primer design tool (exclude orthologs) • Increase SF definitions for: virulence, host specificity, replication, etc. • Provide a new tool to assign (or convert between) sequence coordinate schemes
Annotation and Host Factor Data • Ensure sequence submissions are appropriately prepared (i.e. no primer sequence, etc.) • Increase number of host factor datasets • Develop method to handle different statistical methods from various “-omics” platforms (e.g. microarray, proteomics, etc.)
Surveillance • Identify NIAID-funded human surveillance studies and solicit deposition into IRD • Develop additional use-cases to identify additional helpful data types
Immunology • Epitopes • Add search options such as: CD4, CD8, host • Serology • Solicit feedback from community on use-cases • Identify volunteers for data submission
PA-X Prediction for All Strains • Build on analysis performed earlier this year by Jaggeret al.Science 2012 Jul 13;337(6091):199-204 • Identified new protein on segment 3 using ~1000 sequences • Frameshift occurs at codon 190 in PA protein, results in new C-terminus • IRD will extend this analysis across all segment 3’s in resource • Add PA-X annotation to existing IRD sequence records • Allow users to search for PA-X protein sequences • Provide data that can assist in downstream comparative genomics analyses
H5 clade annotation tool • Automated clade determination for any query HA sequence • Match WHO clade definitions
NGS Deep Sequencing Data • Primary data in SRA • Derived data in IRD • Positions with sequence variation • Proportion of read with a particular sequence variation • Metadata to understand the context
