Figure 6From: Microglial phenotypes and toll-like receptor 2 in the substantia nigra and hippocampus of incidental Lewy body disease cases and Parkinson’s disease patients Iba1 immunopositive microglia in the substantia nigra (SN) and hippocampal CA2 region of control subjects, iLBD cases and PD patients. (a,b) Widely distributed Iba1 positive ramified microglial cells (arrow) in a control subject, (c,d) an iLBD case and (e,f) a PD patient. Iba1 positive microglia are present with ramified (arrow), primed/reactive (concave arrowhead) and amoeboid (short arrow) phenotypes; bar (a-f) = 50 μm.Back to article page
