Microglia/macrophages immunohistochemistry and ramification using Sholl analysis were also evaluated. Neutralizing IL-1 resulted in attenuated cell death, indicated by cleaved caspase-3 manifestation, and attenuated loss of adult OLs from two to seven days post-injury in brain-injured animals. IL-1 neutralization also attenuated the early, two day time post-injury increase of microglia/macrophage immunoreactivity and modified their ramification. The proliferation of OPCs in brain-injured animals was not modified, however. Our data suggest that IL-1 is definitely involved in the TBI-induced loss of OLs and early microglia/macrophage activation, although not the OPC proliferation. Attenuated oligodendrocyte cell loss may contribute to the improved behavioral end result observed by IL-1 neutralization with this mouse model of diffuse TBI. on a 12?h light/dark cycle.

Co-localization of cleaved caspase-3/MOG (myelin-oligodendrocyte-glycoprotein) was also made with hybridization to confirm apoptotic OLs. Immunohistochemistry Cleaved caspase-3 staining and staining for CC1 positive adult OLs was used to study OL cell loss. Sections were placed in 1x PBS +0.1% triton and washed 3??5?min.
