Figure 7: Immunohistochemical labeling: TYMP. A-B: Normal cortex shows minimal expression in cortex restricted to scattered microglial cells in grey matter (B). C-D: In cases of TBM, intense expression was seen in meningeal exudates (C, asterix) and microglial cells in cortical ribbon (C, D) and white matter was strongly labeled highlighting branching pattern of activated microglia. E-F: In cases of TBM with HIV, labeling of meningeal exudates (E, asterix) was more intense compared to cases of TBM, while activated microglia in grey matter attained amoeboid morphology (F).
