Figure 4. IL-6 is elevated in Nippo mice.

Levels of (A) TNF-α, (B) IL-6, and (C) IL-1β were measured by ELISA in peritoneal lavage fluid from WT or Nippo mice at baseline, 4 and 24 h after i.p. injection of 150 CFU of K. pneumoniae. (n = 7–9 mice/time point, *P<0.05 for Nippo mice compared to unparasitized control mice).
