正常小鼠肝脏含有显著的CD4⁺8⁻和CD4⁻8⁻ T细胞受体(TCR)-α/β⁺细胞亚群,其TCR水平处于中等。我们在此表明,这些细胞表达自然杀伤(NK)1.1表面抗原,并且具有受限的TCRVβ库,该库高度偏向Vβ7和Vβ8。令人惊讶的是,在β2 - 微球蛋白缺陷型小鼠的肝脏中,NK1.1⁺TCR - α/β⁺细胞的CD4⁺8⁻和CD4⁻8⁻亚群均缺失,这些小鼠不表达主要组织相容性复合体(MHC)I类或“I类样”分子。对用β2 - 微球蛋白缺陷型和野生型小鼠建立的相互辐射骨髓嵌合体的分析表明,辐射敏感(可能是造血)细胞上的MHC I类表达是肝脏中NK1.1⁺TCR - α/β⁺细胞发育所必需的。在MHC II类缺陷型小鼠的肝脏中,NK1.1⁺TCR - α/β⁺细胞的CD4⁺8⁻和CD4⁻8⁻亚群正常发育。总体而言,我们的数据表明肝脏中的NK1.1⁺TCR - α/β⁺细胞需要与造血细胞上的MHC I类相关配体相互作用才能发育。肝脏T细胞的这种特殊性质也为一部分CD4⁻8⁻NK1.1⁺TCR - α/β⁺胸腺细胞所共有,这表明存在一个独立于T细胞发育主流的共同谱系。
Normal mouse liver contains prominent subsets of CD4+8- and CD4-8- T cell receptor (TCR)-alpha/beta+ cells with intermediate TCR levels. We show here that these cells express the natural killer (NK)1.1 surface antigen and have a restricted TCRV beta repertoire that is highly skewed to V beta 7 and V beta 8. Surprisingly, both CD4+8- and CD4-8- subsets of NK1.1+TCR-alpha/beta+ cells are absent in the liver of beta 2-microglobulin deficient mice, which do not express major histocompatibility complex (MHC) class I or "class I-like" molecules. Analysis of reciprocal radiation bone marrow chimeras established with beta 2-microglobulin deficient and wild-type mice demonstrates that MHC class I expression on radiosensitive (presumably hematopoietic) cells is required for the development of NK1.1+TCR-alpha/beta+ cells in the liver. In the liver of MHC class II deficient mice, the CD4+8- and CD4- 8- subsets of NK1.1+TCR-alpha/beta+ cells develop normally. Collectively our data suggest that NK1.1+TCR-alpha/beta+ cells in liver require interaction with a MHC class I-related ligand on hematopoietic cells for their development. This unusual property of liver T cells is shared by a subset of CD4-8-NK1.1+TCR-alpha/beta+ thymocytes, suggesting a common lineage independent of the mainstream of T cell development.
