Abstract

Chlamydia trachomatis is a significant pathogen with global and economic impact. As an obligate intracellular pathogen, C. trachomatis resides inside the inclusion, a parasitophorous vacuole, and depends on the host cell for survival and transition through a biphasic development cycle. During infection C. trachomatis is known to manipulate multiple signaling pathways and recruit an assortment of host proteins to the inclusion membrane, including host kinases. Here we show recruitment of multiple isoforms of Protein Kinase C (PKC) including active phosphorylated PKC isoforms to the chlamydial inclusion colocalizing with active Src family kinases. Pharmacological inhibition of PKC led to a modest reduction of infectious progeny production. PKC phosphorylated substrates were seen recruited to the entire periphery of the inclusion membrane. Infected whole cell lysates showed altered PKC phosphorylation of substrates during the course of infection. Assessment of different chlamydial species showed recruitment of PKC and PKC phosphorylated substrates were limited to C. trachomatis. Taken together, PKC and PKC substrate recruitment may provide significant insights into how C. trachomatis manipulates multiple host signaling cascades during infection.
