S100b Counteracts Neurodegeneration of Rat Cholinergic Neurons in Brain Slices after Oxygen-Glucose Deprivation

Figure 1

Immunohistochemistry for cholinergic choline acetyltransferase (ChAT) positive neurons (a)–(c) and c-fos immunoreactive nuclei (d)–(f) in organotypic brain slices of the basal nucleus of Meynert. Slices show control stainings before ((a), (c), (d)), or 3 days (ChAT⁺, (b)) or 3 hours (c-fos+, (e) and (f)) after oxygen-glucose deprivation. Scale bar in 𝐴=300 𝜇m ((a), (b), (d), and (e)) and 75 𝜇m ((c) and (f)).
