Review Dr. Tanzi’s full biography and publications.
A legacy of discovery
For more than four decades, Dr. Tanzi’s groundbreaking research has transformed how neurodegenerative diseases are understood and treated. From co-discovering all three genes associated with familial early-onset Alzheimer’s disease and co-inventing gamma-secretase modulators (GSMs) as a new class of therapeutics to pioneering Alzheimer’s-in-a-Dish™, his accomplishments have established him as one of the world’s most influential neuroscientists. His work continues to shape the global pursuit of Alzheimer’s prevention, treatment, and a cure.
Helped find the Huntington’s disease gene (with Dr. James F. Gusella) – the first disease gene to ever be found by genetic linkage analysis
Discovered the first early-onset familial Alzheimer’s disease gene, the amyloid precursor protein (APP)
Constructed the first complete genetic map of a human chromosome
Provided the chromosome map that led to the first familial ALS (Lou Gehrig’s disease) gene (SOD-1)
Discovered the gene responsible for the neurodegenerative disease causing Wilson’s disease
Showed zinc and copper drive the formation of toxic amyloid in the brain leading to Alzheimer’s disease
Co-discovered the second and third early-onset familial Alzheimer’s disease genes – presenilin 1 (PSEN1) and presenilin 2 (PSEN2)
On team that showed how the three early-onset familial Alzheimer’s disease genes lead to toxic brain amyloid and Alzheimer’s disease
Discovered the alpha-2 macroglobulin gene is associated with risk for late-onset Alzheimer’s disease
Reported the most common genetic risk factor for late-onset Alzheimer’s disease, Apolipoprotein E- e4, drives the aggregation of toxic beta-amyloid
Discovered genetic linkage of AD to chromosome 10 near the insulin degrading enzyme (IDE) gene
Conducted the first whole human genome genetic linkage study of late-onset familial Alzheimer’s disease
Reported the drug, clioquinol, blocks beta-amyloid formation and improves cognition in a phase 2 Alzheimer’s disease clinical trial
Discovered the LDL receptor-related protein (LRP) clears beta-amyloid
Discovered human autoantibodies to beta-amyloid that inspired the amyloid immunotherapies later approved to treat Alzheimer’s disease
Discovered the ubiquilin 1 gene is associated with risk for late-onset Alzheimer’s disease
Discovered the common inhalation anesthetic, isoflurane, increases brain levels of beta-amyloid that leads to Alzheimer’s disease
Established widely used gene databases (AlzGene, PDGene, SZGene)
Served on team that discovered one of the first autism genes
Reported the first familial Alzheimer’s disease genome-wide association study that led to the discovery of the first Alzheimer’s disease gene that implicated microglial cells and neuroinflammation in the disease process – CD33
Discovered the Alzheimer’s disease gene, ADAM10, with mutations that increase beta-amyloid production
Discovered that the amyloid beta-protein serves as antimicrobial (host-defense) peptide in the brain leading to the Antimicrobial Protection Hypothesis of Alzheimer’s disease
Discovered beta-amyloid in the lens of Down syndrome and Alzheimer’s patients
Discovered the first potent gamma-secretase modulators (GSM) with Dr. Steve Wagner– now a clinical candidate slated for phase I clinical trials in 2025
Discovered that the “bobble-head” effect in bomb blast leads to traumatic brain injury and Alzheimer’s disease pathology (with Dr. Lee Goldstein)
Discovered CD33 controls beta-amyloid clearance and neuroinflammation in Alzheimer’s disease, making it a drug target
Invented Alzheimer’s-in-a-Dish™, the first 3D human stem cell-derived neural culture AD model that fully recreates Alzheimer’s pathology and provides proof of concept that beta-amyloid causes tau tangles
Showed amyloid-beta protein can protect against infection by bacteria and fungus
Showed with Dr. Sam Sisodia that the gut microbiome can be modified to clear brain beta-amyloid in mice
Reported with Dr. Steve Wagner a highly potent gamma secretase that can lower the production of toxic Ab42 in the brain
Showed amyloid-beta protein can protect against herpes virus 1 (HSV1) infection
Reported exercise can restore cognitive function in Alzheimer’s disease mice and be mimicked with pharmacological treatments
Created the first 3D human cell culture blood brain barrier model of Alzheimer’s disease pathology
Showed the gene responsible for cerebellar ataxia (ATXN1) controls amyloid production in Alzheimer’s disease
Demonstrated that the two Alzheimer’s CD33 and TREM2 have opposite effects on the clearance of brain amyloid and neuroinflammation
Showed that cluster (oligomer) amyloid beta-protein directly induces tangle pathology in Alzheimer’s disease
Reported with Amylyx that the drug Relyvrio™ improves symptoms of ALS in phase 2 clinical trial, leading to subsequent approval
Discovered over a dozen new Alzheimer’s disease genes involved with synaptic function, using whole genome sequencing

The SHIELD Plan, developed by Dr. Tanzi, is a great way to remember how to take care of your brain now. If you can improve your brain health today, you’ll reduce your risk for brain disease in the future.
