How helper proteins recognize harmful tau in Alzheimer's disease
J-domain protein conformational selectivity for tau in disease
This project looks at whether helper proteins called J-domain proteins can recognize and change the harmful shapes of tau that drive Alzheimer's disease.

What this research studies
Scientists will examine how different J-domain proteins bind to the tau protein shapes seen in Alzheimer's and related tauopathies. They will study patient-derived tau samples alongside cell models, cryo-EM structural analysis, and animal experiments to compare interactions with normal versus disease-associated tau. The team will test whether altering J-domain protein activity can reduce tau aggregation in living models. Findings will be used to inform possible diagnostic markers or therapeutic approaches targeting specific tau conformations.
Who could benefit from this research
Good fit: People with Alzheimer's disease or other tau-related disorders who can provide biospecimens (for example, brain tissue or cerebrospinal fluid) or participate in linked sample-collection efforts would be most relevant.
Not a fit: Patients seeking immediate clinical treatment are unlikely to receive direct benefit because the project is focused on laboratory and preclinical research rather than a therapy trial.
Why it matters
Potential benefit: If successful, this work could lead to new diagnostics for harmful tau forms and therapies that prevent or reduce tau aggregation in Alzheimer's and related diseases.
How similar studies have performed: Prior laboratory and patient-sample studies suggest molecular chaperones can influence tau aggregation, but translating these findings into proven human therapies has not yet been achieved.
