Zaireebolavirus (EBOV) is a highly pathogenic filovirus which can result in Ebola virus disease (EVD); a serious medical condition that presents as flu like symptoms but then often leads to more serious or fatal outcomes. The 2013-16 West Africa epidemic saw an unparalleled number of cases. Here we show characterisation and identification of T cell epitopes in surviving patients from Guinea to the EBOV glycoprotein. We perform interferon gamma (IFN gamma) ELISpot using a glycoprotein peptide library to identify T cell epitopes and determine the CD4(+) or CD8(+) T cell component response. Additionally, we generate data on the T cell phenotype and measure polyfunctional cytokine secretion by these antigen specific cells. We show candidate peptides able to elicit a T cell response in EBOV survivors and provide inferred human leukocyte antigen (HLA) allele restriction. This data informs on the long-term T cell response to Ebola virus disease and highlights potentially important immunodominant peptides. T cell responses are known to be essential in the immune response to Ebola virus infection, and the viral glycoprotein is a major antigenic target. Here the authors provide fine detail mapping of T cell antigens and their characterisation in Ebola virus survivor patients.
