    NKGen Biotech Presents Troculeucel Mechanism of Action with Corresponding Phase 1 Biomarker Data at the Alzheimer's Association International Conference 2025

    Troculeucel, a cryopreserved autologous, non-genetically modified NK cell product, appears to cross the blood brain barrier (BBB) via CXCR3, to reduce neuroinflammation via a simple IV administration.
