虽然人类胸腺细胞在免疫治疗方面有着巨大的前景,但它们的生物学变异性对临床应用提出了挑战。在这里,我们检查了新鲜分离和培养扩增的人PBMC来源的Treg的定义子集的临床相关活性。与高度抑制性但可塑性记忆TclG(memTreg)不同,幼稚TclG(nvTreg)表现出最大的增殖、刺激后的抑制能力和Treg谱系保真度。然而,与memTactase不同,nvTactase缺乏岩藻糖基转移酶VII,并显示低sLeX表达,伴随着较差的归巢能力。体外nvTreg扩增增强了它们的抑制功能,但不改变nvTreg sLeX-1 ° w糖组。然而,nvTreg表面的外岩藻糖基化产生高sLeX表达,促进内皮粘附并增强异种aGVHD的抑制。这些数据表明,未成熟的Treg糖组处于独特的调节下,并且成人PBMC可以是自体来源的治疗性Treg的理想来源,前提是进行子集选择和聚糖工程化以优化其免疫调节和对炎症部位的向性。
While human Tregs hold immense promise for immunotherapy, their biologic variability poses challenges for clinical use. Here, we examined clinically-relevant activities of defined subsets of freshly-isolated and culture-expanded human PBMC-derived Tregs. Unlike highly suppressive but plastic memory Tregs (memTreg), naïve Tregs (nvTreg) exhibited the greatest proliferation, suppressive capacity after stimulation, and Treg lineage fidelity. Yet, unlike memTregs, nvTregs lack Fucosyltransferase VII and display low sLeX expression, with concomitant poor homing capacity. In vitro nvTreg expansion augmented their suppressive function, but did not alter the nvTreg sLeX-l ° w glycome. However, exofucosylation of the nvTreg surface yielded high sLeX expression, promoting endothelial adhesion and enhanced inhibition of xenogeneic aGVHD. These data indicate that the immature Treg glycome is under unique regulation and that adult PBMCs can be an ideal source of autologous-derived therapeutic Tregs, provided that subset selection and glycan engineering are engaged to optimize both their immunomodulation and tropism for inflammatory sites.
