Severity of inflammatory bowel disease in IL-10 gene-targeted mice is in part determined by genetic back-ground. In the current study, a targeted IL-10 gene was transferred into the C3H/HeJBir substrain, known to exhibit high T-cell and B-cell responses to enteric flora, and to be highly sensitive to colitigenic stress. IL-10-deficient C3H/HeJBir mice developed early onset colitis in contrast to IL-10-deficient C57BL/6J congenic mice. Histopathologic analysis of disease in C3H/HeJBir.Il10-/- and C57BL/6J.Il10-/- mice showed significant differences at all ages studied. Hybrids of these congenic strains (F1.Il10-/-) were produced to study the mode of inheritance as well as subphenotypes that correlated with his-topathology. Lesions in F1 mice were intermediate between parental strains. C3H-contributed subphenotypes that correlated best with histopathology were peripheral blood granulocyte percentage, serum amyloid A concentration, spleen weight/body weight ratio, and mesenteric lymph node weight/ body weight ratio. Neither enhanced humoral immunity (secretory IgA; anti-Escherichia coli cellular membrane Ig) characteristic of C3H/HeJBir, nor T-cell percentages in peripheral blood correlated as well. This study represents a necessary step in elucidating murine genetic modifiers controlling colitis sensitivity.
