Infection with Francisella tularensis, the causative agent of the human disease tularemia, results in the overproduction of inflammatory cytokines, termed the cytokine storm.
Excess metabolic byproducts of obesity accumulate in obese individuals and activate the same inflammatory signaling pathways as F.
tularensis infection.
In addition, elevated levels of leptin in obese individuals also increase inflammation.
Since leptin is produced by adipocytes, we hypothesized that increased fat of obese females may make them more susceptible to F.
tularensis infection compared with lean individuals.
Lean and obese female mice were infected with F.
tularensis and the immunopathology and susceptibility monitored.
Plasma and tissue cytokines were analyzed by multiplex ELISA and real-time RT-PCR, respectively.
Obese mice were more sensitive to infection, developing a more intense cytokine storm, which was associated with increased death of obese mice compared with lean mice.
This enhanced inflammatory response correlated with in vitro bacteria-infected macrophage cultures where addition of leptin led to increased production of inflammatory cytokines.
We conclude that increased basal leptin expression in obese individuals causes a persistent low-level inflammatory response making them more susceptible to F.
tularensis infection and heightening the generation of the immunopathological cytokine storm.
