Micoy Therapeutics develops therapeutics and companion diagnostics that target harmful autoantibodies. Our lead programs address autoantibodies against Type I Interferons, which weaken antiviral immunity, and against Folate Receptor alpha (FRα), which block folate transport and are linked to infertility, pregnancy loss, and neurodevelopmental disorders. We are creating safe “decoy” biologics and rapid blood tests to identify and neutralize these autoantibodies early.
Learn MoreThe immune system is meant to protect us from harm—but sometimes it turns against the body’s own essential molecules. Micoy Therapeutics is uncovering this hidden layer of immune dysfunction: autoantibodies that block critical biological pathways and quietly contribute to disease.
Our work bridges immunology, protein engineering, and diagnostic innovation to detect and neutralize these harmful antibodies. By combining rapid blood tests, we aim to identify risk early, restore balance, and prevent long-term health effects.
Folate is essential for cell growth, fertility, and brain development. Some people develop autoantibodies against the Folate Receptor alpha (FRα) — the protein responsible for transporting folate into cells. These FRAAs can block folate uptake even when blood levels appear normal, leading to infertility, pregnancy loss, and neurodevelopmental disorders.
Micoy is developing NeuroLume™, a rapid, finger-prick test that detects FRAAs in minutes. This easy-to-use tool will help clinicians identify at-risk individuals early and guide folate-based interventions to support reproductive and neurological health.

Type I interferons are key immune molecules that protect against viral infections. In some individuals, autoantibodies against interferons can neutralize these natural defenses, increasing susceptibility to severe illness.
Micoy is developing diagnostic assays to detect these autoantibodies and therapeutic decoys that safely neutralize them, helping restore normal immune protection.
Across both programs, Micoy is building a platform that links precision diagnostics with targeted therapeutics. Our mission is to reveal how autoantibodies shape human health—and to create practical solutions that restore balance and resilience across the lifespan.
Micoy Therapeutics is seeking accredited investors to join us in developing decoy therapies and restore immune function.
