Immunohistochemical labeling of NFASC protein overexpressed in TBM. Normal controls (A, B): Light labeling of the cortical ribbon (A) in the frontal cortex with synaptic pattern (B). TBM(C-G): Whole mount preparation (C) highlight the darker labeling of the cortical ribbon and the inflammatory exudate in the subarachnoid space. The macrophages (E) entrapped in the inflammatory exudate are strongly labeled. Glial cells (F, arrows) and linearly arranged neuronal cytoplasm (G, arrows) are strongly labeled in the grey matter. [A, C: x10, B, D: xObj.5, E-G: xObj.20].
