    • Methods are described for diagnosis of a lymphoid hematological malignancy in a subject prior to treatment, and for detecting minimal residual disease (MRD) in the subject after treatment for the malignancy, by high throughput quantitative sequencing (HTS) of multiple unique adaptive immune receptor (TCR or Ig) encoding DNA molecules that have been amplified from DNA isolated from blood samples or other lymphoid cell-containing samples. Amplification employs oligonucleotide primer sets designed to amplify CDR3-encoding sequences within substantially all possible human VDJ or VJ combinations. Disease-characteristic adaptive immune receptor clonotypes occur, prior to treatment, at a relative frequency of at least 15-30% of rearranged receptor CDR3-encoding gene regions. Following treatment, persistence of at least one such clonotype at a detectable frequency of at least 10−6 or at least 10−5 receptor CDR3-encoding regions indicates MRD. Improved quantitative embodiments are provided by inclusion of a template composition for amplification factor determination and related methods.
    • 描述了用于在治疗前对受试者的淋巴血液恶性肿瘤进行诊断的方法,以及通过多种独特的适应性免疫受体的高通量定量测序(HTS)检测治疗恶性肿瘤后受试者中的最小残留病变(MRD) TCR或Ig)编码从分离自血液样本或其他含淋巴细胞样品的DNA扩增的DNA分子。 扩增使用设计用于在基本上所有可能的人类VDJ或VJ组合中扩增CDR3编码序列的寡核苷酸引物组。 疾病特征适应性免疫受体克隆型在治疗前以相对频率发生在重排的受体CDR3编码基因区域的至少15-30%。 在治疗后,以至少10-6或至少10-5个受体CDR3编码区的可检测频率持续存在至少一种此类克隆型,表示MRD。 通过包括用于扩增因子测定的模板组合物和相关方法来提供改进的定量实施方案。

    • The invention is directed to methods for determining antigen-specific T cells. In some embodiments, methods of the invention may be implemented by the steps of reacting under interaction conditions one or more antigens with T cells in a plurality of subsets of a tissue sample, such as peripheral blood; sorting antigen-interacting T cells from other T cells; separately sequencing for each subset recombined nucleic acid encoding a segment of a TCR chain from a sample of T cells prior to exposure to antigen and from a sample of T cells isolated based on their interaction with antigen, thereby forming a clonotype profile for the former sample and the latter sample for each subset; and identifying as antigen-specific T cells those T cells associated with a clonotype whose frequency increases in the latter sample relative to its frequency in the former sample.
    • 本发明涉及确定抗原特异性T细胞的方法。 在一些实施方案中,本发明的方法可以通过以下步骤实施:在相互作用条件下使一种或多种抗原与组织样品的多个子集中的T细胞例如外周血反应; 分选来自其他T细胞的抗原相互作用T细胞; 在暴露于抗原之前和从基于它们与抗原的相互作用分离的T细胞样品中分别对来自T细胞样品的编码TCR链区段的每个亚组重组核酸进行测序,由此形成前样品的克隆型谱 以及每个子集的后一个样本; 并鉴定与抗原特异性T细胞相关的与克隆型相关的T细胞,其频率在后者样品中相对于其在前样品中的频率增加。
