摘要
肺巨噬细胞通过特异性和非特异性机制,在先天免疫和免疫反应中发挥作用,即吞噬作用,并且能通过主要组织相容性复合体、T细胞活化与炎性因子的释放而对抗原加工与提呈产生重要影响。尽管他们在正常状态下对损伤有保护作用,但它们能引起多种肺疾病,因为它们可以通过聚集其他炎症细胞形成肺泡空间、释放炎症细胞因子或刺激胶原沉积的来介导疾病过程。肺巨噬细胞是治疗肺病的极佳靶点。随着纳米技术的发展,针对这些细胞的靶向药物的载体已经被科学家所设计。常用的方法之一是使对肺巨噬细胞表面受体具有亲和力的配体附着在纳米载体上。本综重点讲述了肺巨噬细胞在宿主防御中的重要性、其对不同肺疾病的影响,以及肺泡巨噬细胞的靶向性的不同措施。

摘要: Lung macrophages present an effective role in innate and immune response through specific and non-specific mechanisms, namely phagocytosis, antigen processing and presentation through major histocompatibility complex, activation of T cells and inflammatory cytokines release. Despite their protective role against injury in normal condition, they can cause several lung conditions, since they can mediate several processes, through recruitment of other inflammatory cells for alveolar space, release of proinflammatory cytokines or stimulation of collagen deposition. Lung macrophages constitute a good therapeutic target. With the development of nanotechnology, new carriers have been designed to target drugs towards these cells. One of the commonly used approaches is the attachment of ligands with affinity to receptors presented at lung macrophage surface, to the nanocarriers. This review will focus on the importance of lung macrophages in host-defense, their influence on different pulmonary diseases and different strategies for alveolar macrophage targeting.
