Abstract

Chromobacterium violaceum produces autoinducers, including homoserine lactones (HSLs), for genetic regulation. Among the seven HSLs derived from C. violaceum we evaluated, only C(12)-HSL stimulated the production of inflammatory cytokines in mammalian monocytic cell lines through the activation of the NF-kappaB signaling pathway besides their quorum-sensing role, like 3-oxo-C(12)-HSL from Pseudomonas aeruginosa.

摘要

紫色色杆菌产生自诱导物,包括高丝氨酸内酯(HSLs),用于基因调控。在我们评估的源自紫色色杆菌的七种HSLs中,只有C(12)-HSL除了具有群体感应作用外,还通过激活NF-κB信号通路刺激哺乳动物单核细胞系中炎性细胞因子的产生,就像铜绿假单胞菌的3-氧代-C(12)-HSL一样。
