SUMMARYThe lipid homeostasis pathways of bacterial pathogens have been studied comprehensively for their biochemical functionality. However, new and refined technologies have supported the interrogation of bacterial lipid and fatty acid homeostasis mechanisms in more complex environments, such as mammalian host niches. In particular, emerging findings on the breadth and depth of host fatty acid uptake have demonstrated their importance beyond merely fatty acid utilization for membrane synthesis, as they can contribute to virulence factor regulation, pathogenesis, and group-based behaviors. Lipid homeostasis is also intertwined with other metabolic and physiological processes in the bacterial cells, which appear to be largely unique per species, but overarching themes can be derived. This review combines the latest biochemical and structural findings and places these in the context of bacterial pathogenesis, thereby shedding light on the far-reaching implications of lipid homeostasis on bacterial success.
