Adoptive transfer of virus-specific T cells (VSTs) represents a prophylactic and curative approach for opportunistic viral infections and reactivations after transplantation. However, inadequate frequencies of circulating memory VSTs in the T-cell donor’s peripheral blood often result in insufficient enrichment efficiency and purity of the final T-cell product, limiting the effectiveness of this approach. This pilot study was designed as a cross-over trial and compared the effect of a single bout (30 min) of high-intensity interval training (HIT) with that of 30 min of continuous exercise (CONT) on the frequency and function of circulating donor VSTs. To this end, we used established immunoassays to examine the donors’ cellular immune status, in particular, with respect to the frequency and specific characteristics of VSTs restricted against Cytomegalovirus (CMV)-, Epstein–Barr-Virus (EBV)- and Adenovirus (AdV)-derived antigens. T-cell function, phenotype, activation and proliferation were examined at different time points before and after exercise to identify the most suitable time for T-cell donation. The clinical applicability was determined by small-scale T-cell enrichment using interferon- (IFN-) γ cytokine secretion assay and virus-derived overlapping peptide pools. HIT proved to be the most effective exercise program with up to fivefold higher VST response. In general, donors with a moderate fitness level had higher starting and post-exercise frequencies of VSTs than highly fit donors, who showed significantly lower post-exercise increases in VST frequencies. Both exercise programs boosted the number of VSTs against less immunodominant antigens, specifically CMV (IE-1), EBV (EBNA-1) and AdV (Hexon, Penton), compared to VSTs against immunodominant antigens with higher memory T-cell frequencies. This study demonstrates that exercise before T-cell donation has a beneficial effect on the donor’s cellular immunity with respect to the proportion of circulating functionally active VSTs. We conclude that a single bout of HIT exercise 24 h before T-cell donation can significantly improve manufacturing of clinically applicable VSTs. This simple and economical adjuvant treatment proved to be especially efficient in enhancing virus-specific memory T cells with low precursor frequencies.

同种异体过继性T细胞免疫疗法中的高强度间歇训练-HIT大吗?

病毒特异性T细胞(VST)的过继转移代表了机会性病毒感染和移植后再激活的预防和治疗方法。但是,T细胞供体外周血中循环记忆VST的频率不足通常会导致最终T细胞产物的富集效率和纯度不足,从而限制了该方法的有效性。这项初步研究旨在作为一项交叉试验,并比较了单次练习(30分钟)和高强度间歇训练(HIT)与30分钟连续运动(CONT)对循环频率和功能的影响供体VST。为此,我们使用既定的免疫分析方法检查了供体的细胞免疫状态,特别是,限制针对巨细胞病毒(CMV),爱泼斯坦-巴尔病毒(EBV)和腺病毒(AdV)衍生的抗原的VST的频率和特定特征。在运动前后的不同时间点检查T细胞功能,表型,激活和增殖,以确定最合适的T细胞捐赠时间。通过使用干扰素(IFN-)γ细胞因子分泌分析和病毒衍生的重叠肽库进行小规模T细胞富集来确定临床适用性。HIT被证明是最有效的运动计划,其VST响应高出五倍。一般而言,具有适度健身水平的供体的VST开始和运动后频率要比高度适合的供体,后者的VST频率运动后增加幅度要低得多。与针对记忆力较高的T细胞频率的针对免疫优势抗原的VST相比,这两种运动计划均提高了针对较少免疫优势抗原的VST的数量,特别是CMV(IE-1),EBV(EBNA-1)和AdV(Hexon,Penton)。这项研究表明,就循环功能活性VST的比例而言,捐献T细胞之前的锻炼对捐献者的细胞免疫具有有益的影响。我们得出的结论是,在捐赠T细胞前24小时进行一次HIT运动可以显着改善临床上可应用的VST的制造。事实证明,这种简单且经济的佐剂处理在增强低前体频率的病毒特异性记忆T细胞方面特别有效。与具有更高记忆T细胞频率的针对免疫优势抗原的VST相比。这项研究表明,就循环功能活跃的VST的比例而言,捐献T细胞之前的锻炼对捐献者的细胞免疫具有有益的影响。我们得出的结论是,在捐赠T细胞前24小时进行一次HIT锻炼可以显着改善临床上可应用的VST的制造。事实证明,这种简单且经济的佐剂处理在增强低前体频率的病毒特异性记忆T细胞方面特别有效。与针对具有更高记忆T细胞频率的免疫优势抗原的VST相比。这项研究表明,就循环功能活性VST的比例而言,捐献T细胞之前的锻炼对捐献者的细胞免疫具有有益的影响。我们得出的结论是,在捐赠T细胞前24小时进行一次HIT运动可以显着改善临床上可应用的VST的制造。事实证明,这种简单且经济的佐剂处理在增强低前体频率的病毒特异性记忆T细胞方面特别有效。我们得出的结论是,在捐赠T细胞前24小时进行一次HIT运动可以显着改善临床上可应用的VST的制造。事实证明,这种简单且经济的佐剂处理在增强低前体频率的病毒特异性记忆T细胞方面特别有效。我们得出的结论是,在捐赠T细胞前24小时进行一次HIT运动可以显着改善临床上可应用的VST的制造。事实证明,这种简单且经济的佐剂处理在增强低前体频率的病毒特异性记忆T细胞方面特别有效。
