摘要： Despite Staphylococcus aureus (S. S. aureus) ) being a highly studied zoontic bacterium, its enteropathogenicity remains elusive. Herein, our findings demonstrated that S. aureus infection led to the accumulation of lipid droplets (LDs) in intestinal epithelial cells, accompanied by marked elevation inflammatory response that ultimately decreases intracellular bacterial load. The aforestated phenomenon may be partly attributed to the up-regulation of hypoxia-inducible lipid droplet-associated protein (HILPDA) and the concomitant down-regulation of cystathionine beta- synthase (CBS) protein. Moreover, S. aureus infection up-regulated the expression of HILPDA, thereby promoting LDs accumulation, and down-regulated that of CBS, consequently inhibiting microsomal triglyceride transfer protein (MTTP) expression. This process may suppress the transport of LDs to the extra- cellular environment, further contributing to the formation of intracellular LDs. In summary, the results of this study provide significant insights into the intricate mechanisms through which the host organism combats pathogens and maintains the balance of sulfur and lipid metabolism. These findings not only enhance our understanding of the host's defense mechanisms but also offer promising avenues for the development of novel strategies to combat intestinal infectious diseases.
