中枢记忆性T细胞和效应记忆性T细胞

Central Memory T Cells and Effector Memory T Cells

免疫记忆是适应性免疫应答的重要特征,其细胞学基础的阐明是疫苗开发和疾病预防的关键。近年来的研究表明,记忆性T细胞可以被进一步划分为中枢记忆性T细胞和外周记忆性T细胞2个亚群,它们的分布和功能迥异,在生物学特性上也不尽相同。二者关系的深入探讨对于免疫记忆的认识和疾病防治均具有重大的理论和实践意义。

Immunological memory is an important characteristic of adaptive immune response and elucidation of its cellular basis is critical for vaccine exploration and disease prevention. Recent studies have shown that memory T cells could be divided into central memory T cells and effector memory T ceils, which were different in distribution, function and biological characteristics. Further investigations on their relationship may contribute to our understanding of immunological memory and the clinical therapy of tumor.
