T cell vaccination (TCV) activates Tregs of 2 kinds: anti-idiotypic (anti-id) and anti-ergotypic (anti-erg). These regulators furnish a useful view of the physiology of T cell regulation of the immune response. Anti-id Tregs recognize specific effector clones by their unique TCR CDR3 peptides; anti-id networks of CD4+ and CD8+ Tregs have been described in detail. Here we shall focus on anti-erg T regulators. Anti-erg T cells, unlike anti-id T cells, do not recognize the clonal identity of effector T cells; rather, anti-erg T cells recognize the state of activation of target effector T cells, irrespective of their TCR specificity. We consider several features of anti-erg T cells: their ontogeny, subset markers, and target ergotope molecules; mechanisms by which they regulate other T cells; mechanisms by which they get regulated; and therapeutic prospects for anti-erg upregulation and downregulation.
T细胞疫苗接种(TCV)可激活两种调节性T细胞(Tregs):抗独特型(抗id)和抗效应型(抗erg)。这些调节细胞为免疫反应中T细胞调节的生理学提供了一个有用的视角。抗id Tregs通过其独特的TCR CDR3肽识别特定的效应克隆;CD4+和CD8+ Tregs的抗id网络已得到详细描述。在此,我们将重点关注抗erg T调节细胞。与抗id T细胞不同,抗erg T细胞不识别效应T细胞的克隆身份;相反,抗erg T细胞识别靶效应T细胞的激活状态,而不考虑其TCR特异性。我们将探讨抗erg T细胞的几个特征:它们的个体发生、亚群标志物和靶效应表位分子;它们调节其他T细胞的机制;它们自身被调节的机制;以及抗erg上调和下调的治疗前景。
