The mechanisms underlying the inhibition of T-cell proliferation by methylprednisolone (MPS) have been investigated using a T-cell colony assay. Cell fractionation experiments have demonstrated that MPS exerted its effects at the level of both T-cells and monocytes. Thus, monocytes treated with MPS released a soluble factor that had suppressor activity on T-cell proliferation. Moreover, MPS directly blocked the proliferative capacity of T-cells, as demonstrated by the finding that MPS-treated T-cells formed reduced numbers of colonies even under optimal culture conditions and in the presence of exogenous IL-2.
已使用T细胞集落测定法研究了甲基强的松龙(MPS)抑制T细胞增殖的潜在机制。细胞分级分离实验表明,MPS在T细胞和单核细胞水平上均发挥作用。因此,用MPS处理的单核细胞释放出一种对T细胞增殖具有抑制活性的可溶性因子。此外,MPS直接阻断T细胞的增殖能力,这一发现表明,即使在最佳培养条件下且存在外源性白细胞介素-2的情况下,经MPS处理的T细胞形成的集落数量也会减少。
