IL10RA and inflammatory response: Following induction of acute lung inflammation with papain, we found that compared to control and IgG1-treated T. muris-infected (T. muris IgG1) mice, anti-IL-10R-treated T. muris-infected (T. muris anti-IL-10R) mice trended toward an increase in total airway cellular infiltration as measured by total BAL fluid cell counts comprised of mainly neutrophils (Fig. 7B).
