RBL1 and colitis: Contrary to the groups of C57BL/6 mice subjected to the induction of experimental colitis where local IL-10 levels were similar to NC (Figure 5), local IL-10 levels remained elevated in recovered BALB/c mice (compared to NC: p ˂ 0.005 for rBL0.1, p ˂ 0.001 for rBL1, rBL10, and PC).
