Peripheral blood lymphocytes (PBL) from cats infected with feline immunodeficiency virus (FIV) were examined for the occurrence of apoptosis after short-term culture. In the PBL from FIV-infected cats, changes in flow-cytometry scattergram, morphological characteristics of apoptosis and nucleosomal DNA fragmentation were observed. Percentages of apoptotic cells by flowcytometry analysis in PBL from FIV-infected cats (22.4% +/- 9.4%) were significantly higher than those in PBL from uninfected control cats (9.2% +/- 3.5%). The lymphocytes which underwent apoptosis included CD5+, CD4+ and sIgM+ cells, indicating that induction of apoptosis was not restricted to a special subset of lymphocytes. These findings provide evidence of the apoptotic state of PBL in cats with FIV infection.
对感染猫免疫缺陷病毒（FIV）的猫的外周血淋巴细胞（PBL）进行短期培养后，检测其凋亡情况。在感染FIV的猫的PBL中，观察到流式细胞仪散射图的变化、凋亡的形态学特征和核小体DNA片段化。通过流式细胞术分析，感染FIV的猫的PBL中凋亡细胞的百分比（22.4%±9.4%）显著高于未感染对照猫的PBL（9.2%±3.5%）。发生凋亡的淋巴细胞包括CD5 +、CD4 +和sIgM +细胞，这表明凋亡的诱导并不局限于淋巴细胞的特定亚群。这些发现为FIV感染猫的PBL的凋亡状态提供了证据。
