Intraperitoneal administration of group A streptococcal cell walls to Lewis rats induces a chronic arthritis, whereas the Fischer strain is resistant to the development of the lesion. Spleen cells from cell wall-treated rats (Lewis and Fischer) are deficient in the synthesis of IL-2. Using an mAb directed against the rat IL-2-R, the present studies indicate that the expression of IL-2-R on spleens of cell wall-treated rats is normal. However, the addition of exogenous IL-2 to spleen cells cultured with Con A does not stimulate the mitogenic response.
给Lewis大鼠腹腔注射A组链球菌细胞壁可诱发慢性关节炎,而Fischer品系大鼠对该病变的发展具有抗性。用细胞壁处理过的大鼠(Lewis和Fischer)的脾细胞合成白细胞介素-2(IL-2)的能力不足。利用一种针对大鼠IL-2受体的单克隆抗体,目前的研究表明,用细胞壁处理过的大鼠脾脏上IL-2受体的表达是正常的。然而,向用刀豆蛋白A培养的脾细胞中添加外源性IL-2并不能刺激有丝分裂反应。
