Effects of overexpression of caRhoA on SHP2 deletion–resultant inflammatory cell infiltration into lungs and airway hyperreactivity. Mice with the indicated genotypes were sensitized and subsequently challenged with OVA; 24 h after the last OVA challenge, mice were subjected to preparation of BALFs for inflammatory cell counting and classification (A), paraffin-embedded sections, H&E staining, and CCR3 immunostaining (B), examination of methacholine-provoked airway hyperreactivity (C) (n = 6). Square frames define the magnifiesd regions. +P < 0.05; ++P < 0.01 vs.
