Liposome-based immunotherapy against autoimmune diseases: therapeutic effect on multiple sclerosis.
Nanomedicine (Lond). 2017 Jun;12(11):1231-1242.

    AIM: Based on the ability of apoptosis to induce immunological tolerance, liposomes were generated mimicking apoptotic cells, and they arrest autoimmunity in Type 1 diabetes. Our aim was to validate the immunotherapy in other autoimmune disease: multiple sclerosis.

    MATERIALS & METHODS: Phosphatidylserine-rich liposomes were loaded with disease-specific autoantigen. Therapeutic capability of liposomes was assessed in vitro and in vivo.

    RESULTS: Liposomes induced a tolerogenic phenotype in dendritic cells, and arrested autoimmunity, thus decreasing the incidence, delaying the onset and reducing the severity of experimental disease, correlating with an increase in a probably regulatory CD25+ FoxP3- CD4+ T-cell subset.

    CONCLUSION: This is the first work that confirms phosphatidylserine-liposomes as a powerful tool to arrest multiple sclerosis, demonstrating its relevance for clinical application.
