摘要

Among white blood cells (WBCs), neutrophils are the most abundant and multifunctional immune cells in the blood, which are also involved in diverse physiological and pathological processes, particularly affecting the deterioration of the tumor. Neutrophil extracellular traps (NETs), composed of chromatin DNA studded with granule proteins, play a crucial role in reactive sterile inflammation. Recently, neutrophils have garnered focus in cancer research due to their participation in cancer initiation, proliferation and metastasis. As important players in the tumor microenvironment (TME), tumor-associated neutrophils (TANs) are viewed as “a double-edged sword” in cancer pathophysiology.In this review, we introduce the NETs formation and associated signaling pathways. Meanwhile, recent studies on the mechanisms through by which neutrophils could promote tumors development will be described. Additionally, we outline the complex complicated molecular mechanisms underlying cancer therapy resistances and associated preface tumor treatment. Finally, we highlight latest advances in NETs-targeting treatment strategies designed to improve the efficacy of cancer therapies.
