Analysis of global temporal gene expression by human intestinal cells when exposed to Lactobacillus acidophilus revealed induction of immune-related pathways and NF-κB target genes after a 1-h exposure, compared to a 4- or 8-h exposure. Additionally, an L. acidophilus derivative expressing covalently bound flagellin resulted in increased induction of il8, cxc1, and cxcl2 compared to the parent L. acidophilus.
分析人类肠道细胞暴露于嗜酸乳杆菌时的全球时空调控基因表达,与暴露 4 或 8 小时相比,1 小时暴露后诱导免疫相关途径和 NF-κB 靶基因。此外,与亲本嗜酸乳杆菌相比,表达共价结合鞭毛蛋白的嗜酸乳杆菌衍生物导致 il8、cxc1 和 cxcl2 的诱导增加。
