    • The invention provides a method of obtaining a population of antigen-specific T cells from peripheral blood of a host. An embodiment of the method of the invention comprises (i) dividing PBMCs from peripheral blood of a host into more than one sub-population; (ii) contacting the PBMCs with an antigen and IL-2; (iii) obtaining a sample of PBMCs from each sub-population; (iv) identifying an antigen-reactive sub-population by determining by high throughput quantitative PCR the expression of a factor produced by the PBMCs of each sample; (v) dividing the antigen-reactive sub-population into microcultures; (vi) identifying the antigen-reactive microculture; and (vii) expanding the microculture, thereby obtaining a population of T cells specific for the antigen. The invention also provides a population of T cells obtained by the inventive method, a pharmaceutical composition comprising the same, and a method of treating a disease in a host using the pharmaceutical composition. Related isolating and screening methods are further provided.
    • 本发明提供从宿主的外周血获得抗原特异性T细胞群体的方法。 本发明方法的一个实施方案包括:(i)将来自宿主的外周血的PBMC分成多于一个亚群; (ii)使PBMC与抗原和IL-2接触; (iii)从每个子群体获得PBMC的样品; (iv)通过高通量定量PCR确定由每个样品的PBMC产生的因子的表达来鉴定抗原反应性亚群体; (v)将抗原反应性亚群分为微量培养物; (vi)鉴定抗原反应性微量培养物; 和(vii)扩大微量培养物,从而获得对抗原特异性的T细胞群体。 本发明还提供了通过本发明方法获得的一组T细胞,包含其的药物组合物和使用该药物组合物治疗宿主中的疾病的方法。 进一步提供相关的分离和筛选方法。
