Therefore, to further investigate whether FABP5 increases according to the progression of prion disease, we compared mice intracranially mock inoculated with normal brain homogenates (NBH) or RML scrapie prions for protein levels at 80- (mid-incubation period), 108- (early symptom onset), and 160- (terminal disease onset) days post-infection. Here, FABP5 is linked to infection.
