Modulation of Host Cell Metabolism by .

Propagation of the intracellular bacterial pathogen is strictly bound to its host cells. The bacterium has evolved by minimizing its genome size at the cost of being completely dependent on its host. Many of the vital nutrients are synthesized only by the host, and this has complex implications.

Chronic Chlamydia infection in human organoids increases stemness and promotes age-dependent CpG methylation.

Chronic infections of the fallopian tubes with Chlamydia trachomatis (Ctr) cause scarring and can lead to infertility. Here we use human fallopian tube organoids and genital Ctr serovars D, K and E for long-term in vitro analysis. The epithelial monolayer responds with active expulsion of the bacteria into the lumen and with compensatory cellular proliferation-demonstrating a role of epithelial homeostasis in the defense against this pathogen.

Combined Human Genome-wide RNAi and Metabolite Analyses Identify IMPDH as a Host-Directed Target against Chlamydia Infection.

Chlamydia trachomatis (Ctr) accounts for >130 million human infections annually. Since chronic Ctr infections are extremely difficult to treat, there is an urgent need for more effective therapeutics. As an obligate intracellular bacterium, Ctr strictly depends on the functional contribution of the host cell.
