ITGAM and Splenomegaly: In detail, while splenic CD11b protein expression was only slightly increased or not affected on days 8 and 9 of CSC and day 20 + 30d SH when CSC-induced splenomegaly and splenic GC resistance were absent or only of mild severity, splenic CD11b protein expression was strongly increased on days 15 and 16, when CSC-induced splenomegaly and splenic GC resistance were most pronounced.
