UNLABELLED
, a Gram-negative bacterium with seven serotypes (a-g) according to the structure of its LPS, has been defined as one of the most important pathogens in the development of a dysbiotic periodontal biofilm and the onset of periodontitis (an inflammatory chronic disease of the tissues around the teeth), where the serotype b is characterized as the most virulent compared with the other serotypes. The aim of this study was to evaluate the expression of the macrophage polarization markers M0, M1, and M2 against .
METHODS
THP-1 cells were infected with serotypes a, b, and c. The expression of CD11b, CD4, CD14, and CD68 for M0; IL-6, HLA/DRA, and CXCL10 for M21, and IL-10, CD163, fibronectin-1 or FN1, and CCL17 was evaluated by qPCR at 2 and 24 h after infection.
RESULTS
An increase in the expression of these molecules was induced by all serotypes at both times of infection, showing higher levels of expression to the M1 panel at 2 and 24 h compared to other markers.
CONCLUSIONS
has a role in the macrophage polarization to the M1 phenotype in a non-serotype-dependent manner.
未标记
，一种革兰氏阴性菌，根据其脂多糖结构有七种血清型（a - g），已被定义为在生态失调的牙周生物膜形成和牙周炎（牙齿周围组织的一种慢性炎症性疾病）发病过程中最重要的病原体之一，其中血清型b被认为是与其他血清型相比毒性最强的。本研究的目的是评估巨噬细胞极化标志物M0、M1和M2对 的表达情况。
方法
用血清型a、b和c感染THP - 1细胞。在感染后2小时和24小时通过qPCR评估M0的CD11b、CD4、CD14和CD68；M1的IL - 6、HLA/DRA和CXCL10，以及IL - 10、CD163、纤连蛋白 - 1或FN1和CCL17的表达。
结果
在两个感染时间点，所有血清型均诱导这些分子的表达增加，与其他标志物相比，在2小时和24小时时M1组的表达水平更高。
结论
以非血清型依赖的方式在巨噬细胞向M1表型的极化中起作用。
