Mechanisms of membrane biogenesis and peptidoglycan remodeling during sporulation

我的研究项目旨在了解细菌生长和细胞分裂过程中发生的细胞包膜结构和功能变化。虽然细菌占据了生物圈的每一个生态位，维持着这个星球上的生命，但它们面临着不可预测的环境。为了生存，它们进化出一种复杂的多层细胞包膜结构，由一层或两层膜和网状聚合物（肽聚糖）组成，在允许营养物质和废物选择性通过的同时保护它们。细胞包膜变化的时空调控对细菌的生长和分裂至关重要。此外，细菌的细胞包膜是抗菌剂的主要靶点。因此，对细菌包膜的研究提供了对基本生物过程的洞察，对理解人类健康和疾病至关重要。

My research program seeks to understand the structural and functional changes that occur in the bacterial cell envelope during growth and cell division. Although bacteria occupy every niche in the biosphere and sustain life on this planet, they are faced with unpredictable environments. To survive, they have evolved a sophisticated, multilayered cell envelope structure composed of either one or two membranes and a mesh-like polymer (peptidoglycan) that protects them while allowing the selective passage of nutrients and waste products. Spatial and temporal regulation of changes in the cell envelope is essential to bacterial growth and division. Moreover, the bacterial cell envelope is a major target for antimicrobials. Thus, research into the bacterial cell envelope provides insight into fundamental biological processes and is critical for understanding human health and disease.
