Figure 1. Influence of the host breed and genotype on the PrPd profiles when inoculated with ME7, 79A, 22A and 87V by the combined route. The x axis of the above graph refers to different morphological types of PrPd labeling identified by immunohistochemistry. PrPd types are: ITNR, intraneuronal; ITAS, intrastrocytic; ITMG, intramicroglial; STEL, stellate; SBPL, subpial; SBEP, subependymal; PRVS, perivascular; PVAC, perivacuolar; PART, fine particulate-coalescing; LINR, linear; PNER, perineuronal; EPEN, ependymal; NVPL, non vascular plaques; VASC, vascular plaques.
