Antiviral cytotoxic T cells cross-reactively recognize disparate peptide determinants from related viruses but ignore more similar self- and foreign determinants
We have investigated the reactivities of cytotoxic T (Tc) cells against the two immunodominant, H-2Kk-restricted determinants from the Flavivirus Murray Valley encephalitis virus (MVE), MVE1785 (REHSGNEI) and MVE1971 (DEGEGRVI). The respective Tc cell populations cross-reactively lysed target cells pulsed with determinants from the MVE1785- and MVE1971-corresponding positions of six other flaviviruses, despite low sequence homology in some cases. Notably, anti-MVE1785 Tc cells recognized a...[Show more]
