The first naturally processed peptide synthesized
by a virus and recognized by classical CD8+ T cells
in association with the RT1.Al major histocompatibility
complex class I molecule of the Lewis rat is reported. Borna
disease virus-specific CD8+ T cells recognize
syngeneic target cells pulsed with peptides extracted from Borna
disease virus-infected cells. The predicted peptide sequence ASYAQMTTY
from the viral p40 protein coeluted with the cytotoxic
T-lymphocyte-reactive fraction was identified among natural ligands by
tandem mass spectrometry. Numerous naturally processed peptides derived
from intracellular bacteria, viruses, or tumors and recognized by
CD8+ T cells of man and mice are known, leading to a better
understanding of cellular immune mechanisms against pathogens in these
two species. In contrast, for the rat little information exists with
regard to the function and role of CD8+ T cells as part of
their cellular immune defense system. This first naturally processed
viral epitope in the rat contributes to the understanding of the rat
cellular immune response and might trigger the identification of more
cytotoxic T-lymphocyte epitopes in this animal.
