High-Speed Analysis of Ebola Virus-Related Epitope Data Seeks to ID Therapeutic Targets and Aid Vaccine Development

The effort to develop therapeutics and a vaccine against the deadly Ebola virus disease (EVD) requires a sophisticated understanding of the microorganism and its interaction with the host, especially the host’s immune response. Adding to the challenge, EVD can be caused by any one of five known species within the genus Ebolavirus (EBOV), in the Filovirus family. In a September 9, 2014 press release, it was announced that researchers at the La Jolla Institute for Allergy and Immunology (La Jolla Institute) and the San Diego Supercomputer Center (SDSC) at the University of California, San Diego are now assisting the scientific community by running high-speed online publications of analysis of EBOV-related epitope data being curated in the Immune Epitope Data Base (IEDB), and predicting epitopes using the IEDB Analysis Resource. Dr. Sebastian Maurer-Stroh of Bioinformatics Institute, A*STAR, Singapore is also assisting with analysis of the latest outbreak sequences of Ebola proteins. “These results are the first installment of a series of analysis, whose ultimate goal is to provide a comprehensive overview of the molecular targets of the immune responses to Ebola virus,” said Dr. Julia Ponomarenko, a senior research scientist at SDSC and UCSD PI of IEDB. The recent Ebola outbreak in West Africa has now reached historic proportions, surpassing 1,900 deaths from 3,500 confirmed or probable cases, prompting the World Health Organization (WHO) to declare an international public health emergency, according to recent news reports. Outbreaks of EVD have occurred in Africa in the past; however the current epidemic, caused by Zaire Ebolavirus, has been characterized by its unprecedented breadth and rapid spread.
