肉芽肿是在非感染性疾病以及感染性疾病中发现的免疫细胞的精细聚集体。它是结核病(TB)的标志。主要被认为是一个主机驱动的策略,以限制杆菌和防止传播,最近的发现表明肉芽肿也可以调制成一个有效的工具,以促进微生物的发病机制。未来研究的目的肯定会集中在更好地表征驱动肉芽肿功能调节的机制。在这里,我们提供了独特的观点,从先天性和适应性免疫系统在结核肉芽肿的形成和作用。由于巨噬细胞(M β s)构成了肉芽肿的主体,我们强调了M β极化的新概念及其在杀微生物剂反应和其他活动中的潜在影响,这些活动可能最终影响肉芽肿的命运。或者,我们揭示了B细胞影响肉芽肿内炎症状态的能力。
The granuloma is an elaborated aggregate of immune cells found in non-infectious as well as infectious diseases. It is a hallmark of tuberculosis (TB). Predominantly thought as a host-driven strategy to constrain the bacilli and prevent dissemination, recent discoveries indicate the granuloma can also be modulated into an efficient tool to promote microbial pathogenesis. The aim of future studies will certainly focus on better characterization of the mechanisms driving the modulation of the granuloma functions. Here, we provide unique perspectives from both the innate and adaptive immune system in the formation and the role of the TB granuloma. As macrophages (Mϕs) comprise the bulk of granulomas, we highlight the emerging concept of Mϕ polarization and its potential impact in the microbicide response, and other activities, that may ultimately shape the fate of granulomas. Alternatively, we shed light on the ability of B-cells to influence inflammatory status within the granuloma.
