Abstract

Mounting evidence from animal models has demonstrated that alterations in T-cell receptor (TCR) signaling alone can lead to dramatically skewed differentiation of naive T cells into T(H)2 cells, to T(H)2 effector functions, and to T(H)2-related diseases. There is significant potential relevance of these observations to human disease. Specifically, a number of immunodeficiencies associated with atopic disease might have atopy as a manifestation because of aberrant TCR signaling. It is therefore important to attempt to identify a role for defects in TCR signaling in the pathogenesis of common atopic diseases.

摘要

越来越多的动物模型研究表明,T 细胞受体 (TCR) 信号的改变单独作用就可以导致初始 T 细胞极向分化为 T(H)2 细胞,并获得 T(H)2 效应功能,从而导致 T(H)2 相关疾病。这些观察结果与人类疾病有很大的相关性。具体来说,一些与特应性疾病相关的免疫缺陷可能由于 TCR 信号的异常而表现出特应性。因此,尝试确定 TCR 信号缺陷在常见特应性疾病发病机制中的作用非常重要。
