Neoepobin - Patched

Neoepobin (developmental code: NRG-12β) is a synthetic neuregulin-1 analog. Historically, neuregulins are growth factors crucial for neural development, synaptic plasticity, and myelination. However, native neuregulin-1 has a fatal flaw: it is large, unstable in the bloodstream, and notoriously poor at crossing the blood-brain barrier (BBB).

For patients with PSP, multiple sclerosis, or rare leukodystrophies, the arrival of represents the first credible promise of not just slowing decline, but rebuilding what was lost. neoepobin patched
