About Us

Alector is on a mission to develop therapies that improve healthy function to the brain.

By unlocking the power of immunology, neuroscience, and human genetics, we’re trailblazing immuno-neurology—a visionary therapeutic approach to stop neurodegeneration. Through a combination of relentless curiosity, exquisite science, and a determination to make a difference, we’re building an ambitious pipeline of one-of-a-kind therapeutic candidates that harness the body’s immune system to change the course of brain diseases and beyond.

We’re compelled to seek treatments in the hope of improving the lives of patients, caregivers, and families whose lives are devastated by such diseases as frontotemporal dementia, Alzheimer’s, Parkinson’s, amyotrophic lateral sclerosis, and others.

“Degenerative brain disorders are among the medical frontiers that have yet to be conquered. If we are successful in our mission…Alector will have a profound impact on humanity.”

Arnon Rosenthal, Ph.D.
