Intraneural PrP d accumulation in Golgi neurons of clinically affected BSE challenged deer. PrPd immunohistochemical labelling of the cerebellar cortex using Bar 224 antibody shows accumulation in granular and molecular layers. There is prominent intraneuronal PrPd accumulation in Golgi neurons (arrow). Linear forms of accumulation are also present, one of which is associated with a Golgi neuron cell body (brown pigment denotes PrPd). Bar = 100 μm.
