| Research Abstract |
The feline immunodeficiency virus (FIV) specific cell-mediated immunity was investigated with experimentally FIV infected cats by ^<51>Cr-release assay. For making experimentally FIV infected cats. TM-2 strain of FIV was injected intraperitoneally(i.p.)to six FIV free(Ab negative)randome mazed cats. PBMC was separated from heparinized peripheral blood with Lymphocyte Separation Medium (Organon Teknika, Durham, NC). Fresh and conA activated PBMC was used as effector cells, and T lymphoblastoid cell line(TLCL) infected with TM-2 strain was used as target cells for ^<51>Cr-release assay. The FIV-specific lysis by fresh and conA activated PBMC was very weak in the present assay. The NK activity of PBMC of FIV infected cat against NK sensitive K562 cells was rather weak as compared with that of FIV negative control cat. We are now trying to make Herpes virus recombinant FIV virus to create the better CTL assay system, and also planning to use PBMC stimulated repeatedly with FIV infected autologous TLCL as effector cells for ^<51>Cr-release CTL assay.
