Tumour-associated macrophages (TAMs) represent as much as 50% of the solid mass in different types of human solid tumours including lung, breast, ovarian and pancreatic adenocarcinomas. The tumour microenvironment (TME) plays an important role in the polarisation of macrophages into the M1 phenotype, which is tumour-suppressive, or M2 phenotype, which is tumour promoting. Preclinical and clinical evidences suggest that TAMs are predominantly of the M2 phenotype that supports immune suppression, tumour growth, angiogenesis, metastasis and therapeutic resistance. Hence, significant attention has been focussed on the development of strategies for the modification of TAMs to halt lung cancer progression. The promotion of repolarisation from the M2 to the M1 subtype, or the prevention of M2 polarisation of TAMs in the stromal environment is potential approaches to reduce progression and metastasis of lung cancer. The focus of this article is an introduction to the development and evaluation of therapeutic agents that may halt lung cancer progression the manipulation of macrophage polarisation. This article will address recent advances in the therapeutic efficacy of nanomedicine exploiting surface functionalisation of nanoparticles and will also consider future perspectives.
肿瘤相关巨噬细胞(TAMs)在不同类型的人类实体瘤中占固体肿块的 50%,包括肺癌、乳腺癌、卵巢癌和胰腺腺癌。肿瘤微环境(TME)在巨噬细胞向肿瘤抑制型 M1 表型或肿瘤促进型 M2 表型极化中起着重要作用。临床前和临床证据表明,TAMs 主要是 M2 表型,支持免疫抑制、肿瘤生长、血管生成、转移和治疗耐药性。因此,人们高度关注开发策略来修饰 TAMs 以阻止肺癌的进展。促进从 M2 向 M1 亚型的再极化,或在基质环境中阻止 TAMs 向 M2 极化,是减少肺癌进展和转移的潜在方法。本文的重点是介绍可能阻止肺癌进展的治疗药物的开发和评估,即通过操纵巨噬细胞极化来实现。本文将介绍利用纳米颗粒表面功能化来开发纳米医学的治疗效果的最新进展,并考虑未来的展望。
