Abstract

Splenocytes from adult C57BL6 (H-2b) mice orally inoculated with nonmurine rotaviruses lysed syngeneic rotavirus-infected target cells. Cytotoxic T lymphocytes (CTLs) were responsible for this cytotoxic activity. Cytotoxic activity was (i) detected 7 days after primary oral inoculation; (ii) not detected in uninoculated animals; (iii) specific for rotavirus-infected target cells; (iv) eliminated by treatment with Thy 1.2-specific immunoglobulin M and complement; and (v) restricted at H-2Db. In addition, rotavirus-specific CTLs cross-reacted with target cells infected with different human or animal rotavirus serotypes. Heterotypic protection against rotavirus challenge may be mediated by cross-reactive CTLs.

摘要

用非鼠类轮状病毒经口接种的成年C57BL6(H-2b)小鼠的脾细胞可裂解同基因的轮状病毒感染的靶细胞。细胞毒性T淋巴细胞(CTL)负责这种细胞毒性活性。细胞毒性活性表现为:(i)初次经口接种7天后可检测到;(ii)未接种的动物中未检测到;(iii)对轮状病毒感染的靶细胞具有特异性;(iv)用Thy 1.2特异性免疫球蛋白M和补体处理后消除;(v)受H-2Db限制。此外,轮状病毒特异性CTL与感染不同人或动物轮状病毒血清型的靶细胞发生交叉反应。针对轮状病毒攻击的异型保护可能由交叉反应性CTL介导。
