Clinical disease activity score after DSS treatment.

Assessment of severity in controls (A, B) and DSS treated mice (1% DSS C, D and 1.5% DSS E, F) determined by an overall clinical disease activity score (A, C, E) and specifically by the change in body weight (B, D, F). Untreated controls exhibited low clinical scores (A) and a steady body weight (B). Mice treated with 1% (C, D) or 1.5% DSS (E, F) demonstrated increasing clinical scores and loss of body weight. Cd14^-/- mice showed significantly higher clinical scores and a significantly higher reduction of body weight than WT mice.
