Suckling mice are protected against murine rotavirus-induced gastroenteritis after adoptive transfer of splenic lymphocytes from immunized animals. Adoptive transfer of Thy1(+)-depleted or CD8(+)-depleted lymphocytes abrogated protection against challenge. (We previously found that depletion of Thy1+ or CD8+ lymphocytes from rotavirus-immunized mice decreased rotavirus-specific cytotoxic activity in vitro.) Protection against disease occurred in the absence of rotavirus-specific neutralizing antibodies in the sera of suckling mice. Rotavirus-specific cytotoxic T lymphocytes may be important in either amelioration of acute infection or protection against reinfection.
在将免疫动物的脾淋巴细胞进行过继转移后,乳鼠可免受鼠轮状病毒诱导的胃肠炎。过继转移去除Thy1(+)或CD8(+)的淋巴细胞可消除对攻击的保护作用。(我们之前发现,从轮状病毒免疫的小鼠中去除Thy1+或CD8+淋巴细胞会降低体外轮状病毒特异性细胞毒性活性。)在乳鼠血清中不存在轮状病毒特异性中和抗体的情况下也出现了对疾病的保护作用。轮状病毒特异性细胞毒性T淋巴细胞可能在急性感染的改善或预防再感染方面起重要作用。
