ImmunomeBrowser: a tool to aggregate and visualize complex and heterogeneous epitopes in reference proteins

Sandeep Kumar Dhanda et al. Bioinformatics. .

Abstract

Motivation: Datasets that are derived from different studies (e.g. MHC ligand elution, MHC binding, B/T cell epitope screening etc.) often vary in terms of experimental approaches, sizes of peptides tested, including partial and or nested overlapping peptides and in the number of donors tested.

Results: We present a customized application of the Immune Epitope Database's ImmunomeBrowser tool, which can be used to effectively aggregate and visualize heterogeneous immunological data. User provided peptide sets and associated response data is mapped to a user-provided protein reference sequence. The output consists of tables and figures representing the aggregated data represented by a Response Frequency score and associated estimated confidence interval. This allows the user to visualizing regions associated with dominant responses and their boundaries. The results are presented both as a user interactive javascript based web interface and a tabular format in a selected reference sequence.

Availability and implementation: The 'ImmunomeBrowser' has been a longstanding feature of the IEDB (http://www.iedb.org). The present application extends the use of this tool to work with user-provided datasets, rather than the output of IEDB queries. This new server version of the ImmunomeBrowser is freely accessible at http://tools.iedb.org/immunomebrowser/.

Screenshots for the example output of the customized application of ‘ImmunomeBrowser’. (A) Tabular format listing all the different epitopes mapped to the given reference protein sequence. (B) Area plot for upper and lower bound CI for RF. The line plot shows the number of positive and negative assays or number of responder and not-responder subjects along the positions in reference protein. Hovering the mouse over any position in the reference protein in any of these plots will display the lower and upper bounds of the RF and number of assays/subjects count found as positive and negative (as shown in red rectangle)
