Biomaterials:纤维素纳米晶体调节肺泡巨噬细胞表型和吞噬功能

2019-04-27 不详 网络

纳米纤维素是一种有前景的生物纳米材料,具有吸引人的特性,适用于多种工业应用。纳米纤维素的使用增加可能导致职业暴露和负面的健康结果。然而,关于其健康影响的了解是有限的,并且虽然纳米纤维素暴露可能在肺中诱导急性炎症反应,但潜在的机制是未知的。肺泡巨噬细胞是肺泡颗粒清除中的关键细胞,其活化和功能可能受到各种颗粒的影响。在这里,我们研究了原始纤维素纳米晶体(CNC)的摄取,以及它们对肺泡巨噬细胞极化和生物

纳米纤维素是一种有前景的生物纳米材料,具有吸引人的特性,适用于多种工业应用。纳米纤维素的使用增加可能导致职业暴露和负面的健康结果。然而,关于其健康影响的了解是有限的,并且虽然纳米纤维素暴露可能在肺中诱导急性炎症反应,但潜在的机制是未知的。

肺泡巨噬细胞是肺泡颗粒清除中的关键细胞,其活化和功能可能受到各种颗粒的影响。在这里,我们研究了原始纤维素纳米晶体(CNC)的摄取,以及它们对肺泡巨噬细胞极化和生物学功能的影响。CNC摄取增强了几种细胞因子的分泌,但本身并没有诱导完整的巨噬细胞极化。存在巨噬细胞活化剂如LPS / IFNG和IL4 / IL13的情况下,CNC暴露增强了M1表型标志物的表达和促炎细胞因子和趋化因子的分泌,同时降低了M2标志物。CNC暴露也影响活化的肺泡巨噬细胞的功能,导致突出的细胞因子破裂和改变的吞噬活性。

总之,CNC暴露可能导致巨噬细胞活化和功能的失调,这对肺部的炎症反应至关重要。
