中性粒细胞和多形核骨髓源性抑制细胞 (PMN-MDSC) 具有相同的起源以及许多形态和表型特征。然而,它们具有不同的生物学作用。中性粒细胞是抵御病原体入侵的主要机制之一,而 PMN-MDSC 具有免疫抑制活性,并限制癌症、慢性传染病、创伤、脓毒症和许多其他病理状况中的免疫反应。尽管在健康成年人中,PMN-MDSC 无法或几乎无法检测到,但在癌症和许多其他疾病患者中,它们会不同程度地积累并与中性粒细胞共存。最近的进展可以更好地区分这些细胞并更好地理解它们的生物学作用。越来越多的证据表明 PMN-MDSC 作为病理激活的中性粒细胞,在免疫反应调节中发挥重要作用。在这篇综述中,我们概述了 PMN-MDSC 和中性粒细胞的定义和特征、它们在各种疾病中的病理意义以及它们与其他基质成分的相互作用。
Neutrophils and polymorphonucler myeloid-derived suppressor cells (PMN-MDSC) share origin and many morphological and phenotypic features. However, they have different biological role. Neutrophils are one of the major mechanisms of protection against invading pathogens, whereas PMN-MDSC have immune suppressive activity and restrict immune responses in cancer, chronic infectious disease, trauma, sepsis, and many other pathological conditions. Although in healthy adult individuals, PMN-MDSC are not or barely detectable, in patients with cancer and many other diseases they accumulate at various degree and co-exist with neutrophils. Recent advances allow for better distinction of these cells and better understanding of their biological role. Accumulating evidence indicates PMN-MDSC as pathologically activated neutrophils, with important role in regulation of immune responses. In this review, we provide an overview on the definition and characterization of PMN-MDSCs and neutrophils, their pathological significance in a variety of diseases, and their interaction with other stromal components.
