最近胸腺移出者(RTEs)是最近完成选择和胸腺流出的外周T细胞,并且包含表型和功能上不同于其更成熟的对应物的群体。抗原活化的RTE是比活化的成熟T细胞效力更低的效应物,部分原因是有氧糖酵解减少(可通过外源性IL-2校正),这反过来影响IFN-γ产生。线粒体作为细胞功能的节点调节器,但它们对RTEs独特生物学的贡献尚不清楚。在这里,我们表明,激活小鼠RTEs受损的氧化磷酸化,即使在外源性IL-2的存在下。这种改变的呼吸表型是相对于成熟T细胞,RTEs中CD 28信号传导减少、转氨酶诱导减少和线粒体质量减少的结果。这些结果表明解偶联,由此IL-2调节RTE糖酵解代谢的速率,而RTE线粒体代谢的独特特征是“硬连线”。
Recent thymic emigrants (RTEs) are peripheral T cells that have most recently completed selection and thymic egress and comprise a population that is phenotypically and functionally distinct from its more mature counterpart. Antigen-activated RTEs are less potent effectors than are activated mature T cells, due in part to reduced aerobic glycolysis (correctable by exogenous IL-2), which in turn impacts IFN-γ production. Mitochondria serve as nodal regulators of cell function but their contribution to the unique biology of RTEs is unknown. Here, we show that activated mouse RTEs have impaired oxidative phosphorylation, even in the presence of exogenous IL-2. This altered respiratory phenotype is the result of decreased CD28 signaling, reduced glutaminase induction, and diminished mitochondrial mass in RTEs relative to mature T cells. These results suggest an uncoupling, whereby IL-2 tunes the rate of RTE glycolytic metabolism while the unique profile of RTE mitochondrial metabolism is ‘hard wired’.
