Neutrophils are the first responders to inflammation and infection. Recently, an elevated neutrophil-to-lymphocyte ratio has generally become a prognostic indicator of poor overall survival in cancer. Accordingly, heterogeneous ill-defined neutrophil-like populations have been increasingly recognized as important players in cancer development. In addition, neutrophil granule proteins released upon cell activation have been associated with tumor progression; this differential granule mobilization may allow neutrophils - and possibly associated cancer cells - to leave the bloodstream and enter inflamed/infected tissues. This review discusses and proposes how granule mobilization may facilitate neutrophil-mediated transport of cancer cells into different tissues as well as leading to different cellular phenotypes that underlie remarkable neutrophil plasticity. This concept might inform novel neutrophil-centered approaches to putative cancer therapies.

中性粒细胞脱粒,可塑性和癌症转移。

中性粒细胞是炎症和感染的第一反应者。近来,嗜中性粒细胞与淋巴细胞之比的升高通常已成为癌症总体存活率低的预后指标。因此,异质性不明确的嗜中性粒细胞样人群已被越来越多地认为是癌症发展的重要参与者。另外,细胞活化后释放的中性粒细胞颗粒蛋白与肿瘤进展有关。这种不同的颗粒动员可以使中性粒细胞-以及可能的相关癌细胞-离开血流并进入发炎/感染的组织。这篇综述讨论并提出了颗粒动员如何促进嗜中性粒细胞介导的癌细胞向不同组织的运输以及如何导致构成显着嗜中性粒细胞可塑性的不同细胞表型。这个概念可能会为以中性粒细胞为中心的新型癌症治疗方法提供参考。
