Mutant PrP aggregates from Tg(PG14) and Tg(CJD) mice are toxic to primary neurons.

<p>Cortical neurons from C57BL/6 mice were exposed to ∼15 nM of PrP aggregates purified from Tg(PG14) and Tg(CJD) mice, to the vehicle alone (PBS), or to 15B3-immunoprecipitated P3 fractions from <i>Prnp</i><sup>0/0</sup> mice. Cell survival was quantified by MTT assay after seven days, and expressed as a percentage of untreated cells. Data are the mean±SEM of 8–24 replicates from three independent experiments. **<i>p</i><0.005 and ***<i>p</i><0.0001 <i>vs.</i> untreated (Mann-Whitney test).</p>
