AI Technical Summary
Existing follistatin-based therapies face challenges due to difficulties in expressing follistatin in vitro and its short half-life in vivo, limiting its therapeutic potential.
Development of follistatin fusion proteins incorporating an antigen-binding antibody portion, such as Fab, which enhances expression and stability by binding to albumin, thereby improving half-life and efficacy.
The fusion proteins exhibit improved expression levels and extended half-life, maintaining biological activity and inhibitory effects on activin ligands, making them more effective therapeutic agents.
