Abstract
To determine whether recombinant human (rh) interleukin (IL)-11 disrupts the clearance of microbial pathogens, mice were challenged with Listeria monocytogenes after receiving high-dose rhIL-11, anti-tumor necrosis factor (TNF) monoclonal antibody (MAb), anti-IL-11 MAb, or saline control. The LD50 was not affected by rhIL-11 but was 10-fold lower in the anti-TNF MAb group (P<.001). Plasma IL-6, IL-1beta, and TNF-alpha levels were not different between rhIL-11-treated animals and the control group; however, interferon-gamma levels were significantly reduced by IL-11 treatment (2477 vs. 0 pg/mL, P<.01). Compared with the control group, the quantitative level of L. monocytogenes in hepatic and splenic tissue was unchanged by rhIL-11 but was significantly increased by TNF or IL-11 inhibition. The results indicate that IL-11 down-regulates cytokine production but does not exacerbate systemic infection in the murine Listeria infection model.Entities:
