Mouse lymphocyte populations of one parental H-2 type (A) were specificially depleted of alloreactive potential by filtration through irradiated A X B F1 recipients, and thoracic duct cells were then stimulated with virus in an A X B F1 environment. Experiments using T cells that had previously been exposed to influenza virus in the context of A established that cross-priming for recognition of viral components expressed on H-2-different (B) target cells does not occur. Furthermore, immunologically naive T cells stimulated with vaccinia virus, subsequent to negative selection for reactivity to B, could not be shown to interact with virus-infected cells of type B. Either there is no significant T-cell repertoire for recognition of virus associated with an H-2 determinant not encountered during ontogeny, or such T cells are also alloreactive and are removed during filtration.
一种亲本H-2类型(A)的小鼠淋巴细胞群体通过经照射的A×B F1受体过滤而特异性地消除了同种异体反应潜能,然后在A×B F1环境中用病毒刺激胸导管细胞。使用先前在A背景下接触过流感病毒的T细胞进行的实验表明,不会发生对在H-2不同(B)靶细胞上表达的病毒成分识别的交叉致敏。此外,在用痘苗病毒刺激后,对B无反应性进行阴性选择的免疫未成熟T细胞,未显示出与B型病毒感染细胞相互作用。要么不存在用于识别在个体发育过程中未遇到的与H-2决定簇相关的病毒的重要T细胞库,要么此类T细胞也是同种异体反应性的,并在过滤过程中被清除。
