Nanoparticle compositions and uses thereof

Abstract

The present developments provide methods and compositions for treating and/or preventing autoimmune diseases. In certain aspects, the present disclosure relates to the use of short peptides loaded inside of nanoparticle nanospheres, nanocapsules, or PEGylated nanoparticles. Additionally, peptide-metal nanoparticle drug conjugates are described and disclosed. In some embodiments, these nanoparticles, whether polymer based or metal-conjugated, when linked or coupled to bioactive peptides provided herein, may be capable of interacting with CD40 proteins or CD40 complexes, and thereby may interfere with the ability of CD40 to interact with CD154. The present disclosure also relates to the use of such nanoparticle-peptide conjugates in reducing the inflammatory response, and in particular, the autoimmune inflammatory response. The present disclosure also relates to the use of such short peptides to prevent or reverse autoimmune disease, in particular in type 1 diabetes and multiple sclerosis, in individuals suffering from such diseases.
