The abstract shows that AD/CTE prions containing both tau isoforms cannot efficiently infect cells expressing only 3R or 4R tau, contradicting expectations that mixed prions should interact with either isoform. This suggests unknown conformational or structural constraints that could inform therapeutic targeting.
