Why We Exist

More than 15 million Americans live with autoimmune disease today, cycling through treatments that manage symptoms without ever reaching the source. ai3Bio was founded to change that.

The Science

Our Platform

Two Platforms. One Target: CD161+ T Cells

LNP/mRNA Platform

A lipid nanoparticle delivers mRNA that triggers disease-causing T cells to self-destruct — precisely, in vivo, in one step.

Antibody Platform

A targeting antibody recruits the body's own immune cells to seek out and clear those same disease-causing T cells.
