复杂的多细胞群落的发展过程,包括在形成特化结构期间对单个细胞的程序性消除,显示出原核生物和真核生物之间的基本相似之处。在分子水平上也可能存在机制上的相似之处,因为已经鉴定出与凋亡调节因子Bax/Bcl-2家族相关的细菌蛋白质,这加剧了人们对细菌PCD存在的猜测。在这里,我们回顾了控制金黄色葡萄球菌细胞死亡和裂解的调控网络,并检查了在生物被膜的发展过程中可能影响它们的环境参数。我们假设,在发育中的生物膜中发现的不同环境条件产生了不同的生理信号,协调细胞死亡和裂解效应的差异表达。
The processes involved in the development of complex multicellular communities, including the programmed elimination of individual cells during the formation of specialized structures, exhibits fundamental similarities between prokaryotic and eukaryotic organisms. Mechanistic similarities may also exist at the molecular level, as bacterial proteins hypothesized to be related to the apoptosis regulator Bax/Bcl-2 family, have been identified, fueling speculation about the existence of bacterial PCD. Here we review the regulatory networks controlling cell death and lysis in Staphylococcus aureus and examine the environmental parameters that might influence them during the development of a biofilm. We hypothesize that the heterogeneous environmental conditions found within a developing biofilm generate distinct physiological signals that coordinate the differential expression of cell death and lysis effectors.
