Abstract

Cats that have succumbed to feline infectious peritonitis, an immune-mediated disease caused by variants of feline coronaviruses, show apoptosis and T-cell depletion in their lymphoid organs. The ascitic fluid that develops in the course of the condition causes apoptosis in vitro but only in activated T cells. Since feline infectious peritonitis virus does not infect T cells, and viral proteins did not inhibit T-cell proliferation, we postulate that soluble mediators released during the infection cause apoptosis and T-cell depletion.

摘要

因感染猫冠状病毒变种而引发免疫介导疾病——猫传染性腹膜炎的猫,其淋巴器官会出现细胞凋亡和T细胞耗竭。该病症过程中产生的腹水在体外可导致细胞凋亡,但仅在活化的T细胞中出现这种情况。由于猫传染性腹膜炎病毒不会感染T细胞,且病毒蛋白也不会抑制T细胞增殖,因此我们推测,感染期间释放的可溶性介质会导致细胞凋亡和T细胞耗竭。
