APOM-FC FUSION PROTEINS AND USES THEREOF

Provided herein are engineered fusion proteins comprising ApoM (e.g., human or murine ApoM) fused to a constant region (Fc) of a immunoglobulin G (IgG, e.g., human IgG or murine IgG). In some embodiments, the ApoM-Fc fusion protein further comprises a signal peptide (e.g., IL-2 signal peptide) fused to the ApoM, allowing the fusion protein to be secreted once expressed recombinantly. Methods of using the ApoM-Fc fusion protein or the sponge variants in the treatment of various diseases or disorders are provided.
