N2 - Adenovirus (Ad) infection is a cause of significant morbidity and mortality in hematopoietic stem cell transplant recipients and virus-specific immunotherapy is one option for improved control. Cellular immunity is an important component in suppression of Ad replication but the frequency and population distribution of Ad-specific CD8 T cells has not been systematically investigated. This is an important question in relation to the potential use of these cells for adoptive transfer. To address this question, HLA-peptide multimers were generated for 8 HLA class I-restricted Ad epitopes, which are highly conserved across Ad species.
