Blood p-Tau181 and p-Tau217 Elevated in Systemic Amyloidoses, Not Specific to Alzheimer's Disease

🔬 Protein Info
Gene Symbolblood
Minimally invasiveLess invasive than cerebrospinal fluid collection via lumbar puncture
Primary care applicabilityCan be used in routine clinical settings without specialized infrastructure
High diagnostic accuracyAUC values exceeding 0.90 for distinguishing AD from controls
Cost-effectiveSignificantly cheaper than PET imaging or CSF analysis
Amyloidosis cohortPatients with confirmed systemic AL (immunoglobulin light chain) and ATTR (transthyretin) amyloidosis
Control cohortHealthy individuals and patients with non-amyloid-related polyneuropathy
AD cohortConfirmed Alzheimer's disease patients for comparison
MeasurementsSerum p-tau181 and p-tau217 using certified immunoassays
p-tau217 superiorityp-tau217 better discriminated ATTR from controls than p-tau181
Polyneuropathy independencep-tau217 was elevated even in ATTR patients without peripheral neuropathy
Cardiac involvementPatients with cardiac ATTR showed higher p-tau levels
