Apoptotic bodies in spleens following 30-day MWCNT exposure + 10 days recovery. Light photomicrographs of spleen from control mice (a, b) and exposed mice (c, d) that were histochemically stained with hematoxylin and eosin (a, c) and immunohistochemically stained for CD45R (B cells) and counter stained with hematoxylin (d, d). There are areas of apoptotic cells/bodies (arrows) in periarteriolar T cell areas of the white pulp (WP) in exposed mice but not control mice. WP – white pulp, RP - Red pulp, a – arterioles, bc (M) - B cells in mantle zone of WP
