Abstract:
:Early diagnosis of Alzheimer`s disease (AD) is currently difficult and involves a complex approach including clinical assessment, neuroimaging, and measurement of amyloid-β (Aβ) and tau levels in cerebrospinal fluid (CSF). A better mechanistic understanding is needed to develop more accurate and even presymptomatic diagnostic tools. It has been shown that Aβ derived from amyloid-containing brain tissue has prion-like properties: it induces misfolding and aggregation of Aβ when injected into human amyloid precursor protein (APP) transgenic mice. In contrast, Aβ in the CSF has been less studied, and it is not clear whether it also exhibits prion-like characteristics, which might provide a sensitive diagnostic tool. Therefore, we collected CSF from APP transgenic mice carrying the Swedish mutation (APP23 mice), and injected it intracerebrally into young mice from the same transgenic line. We found that CSF derived Aβ did not induce increased β-amyloidosis, even after long incubation periods and additional concentration. This suggests that Aβ present in the CSF does not have the same prion-like properties as the Aβ species in the brain.
