Detection of anti-rabies virus cytotoxic T lymphocytes in mice of four distinct H-2 haplotypes using target cells persistently infected with ERA rabies virus.
Cells persistently infected with Evelyn-Rokitnicki-Abelseth (ERA) rabies virus were established. The cells were used as stimulator and target cells to compare H-2 restricted cytotoxic T lymphocyte (CTL) responses specific for rabies virus in A/WySnJ (H-2a), C57BL/6J (H-2b), BALB/cByJ (H-2d), A.SW/SnJ (H-2s) and SJL/J (H-2s) mice. Using a 51chromium release assay, it was determined that an effector/target (E/T) ratio of 5:1 was necessary to demonstrate specific lysis of ERA virus persistently infected mouse neuroblastoma (MNB) (H-2a), EL-4 (H-2b) and P815 (H-2d) cells. Effectors at an E:T ratio of only 0.05:1 specifically lysed an SV-40 transformed SJL/J mouse fibroblast (SSSV) (H-2s) target monolayer. The CTL destruction of the SSSV monolayer was observed visually following Giemsa staining. This is the first instance in which a detailed method for detection of murine anti-rabies virus CTLs has been reported. Furthermore, it is the first time target cells persistently infected with rabies virus were used as stimulator cells to amplify CTLs in vitro and as target cells in the CTL assay. It also is the initial report in which rabies specific CTLs were characterized in H-2d and H-2s rabies virus infected mice.
