Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of cells and have a tremendous potential to suppress immune responses. MDSCs accumulate during tumor progression, autoimmunity, chronic infection, transplantation, and other pathological conditions and can potently suppress T-cell function. Here, we discuss recent findings that describe the molecular mechanisms of MDSCs suppressing T-cell immune responses as well as recent observations that MDSCs may have roles in transplant tolerance.
髓系来源的抑制性细胞(MDSCs)是一类异质性细胞群体,具有强大的抑制免疫反应的潜力。在肿瘤进展、自身免疫、慢性感染、移植及其他病理状况下,MDSCs会积聚,并能有效抑制T细胞功能。在此,我们讨论描述MDSCs抑制T细胞免疫反应分子机制的最新研究发现,以及MDSCs可能在移植耐受中发挥作用的最新观察结果。
