Аннотация
Apoptosis is frequently observed in feline lymphocytes in association with feline immunodeficiency virus (FIV) infection. In this study, to investigate the mechanism of FIV-induced apoptosis, levels of Fas and Fas ligand mRNAs were measured by real-time reverse transcription-PCR. In a feline T-lymphoid cell line the amounts of Fas ligand mRNA increased along with the induction of apoptosis after in vitro infection with FIV. In PBMC collected from 10 cats naturally infected with FIV, Fas ligand mRNA levels were significantly higher than those in PBMC from five uninfected cats. These results indicate that the increased expression of Fas ligand may be involved in the induction of apoptosis of lymphocytes in FIV infection.
