Abstract: Golgi bodies hijacked Like many other intracellular pathogens Chlamydia trachomatis depends on host lipids for growth. A mechanism by which Chlamydia can acquire its lipids has now been demonstrated in infected HeLa epithelial cells. In the normal cell the Golgi apparatus acts to modify newly synthesized proteins and lipids for distribution within or outside the cell. The intracellular replication of C. trachomatis triggers the breakdown of the Golgi apparatus to generate functionally intact Golgi ministacks via cleavage of the matrix protein golgin-84. The Golgi ministacks, which align around the bacterial inclusion, appear to provide a conduit through which the pathogen can secure a supply of lipids. This work points to mechanistic involvement of inflammatory caspases and calpains, which may be used as novel molecular targets for antichlamydial agents.
