Engineered immunological niche directs therapeutic development in models of progressive multiple sclerosis.

ABSTRACT: Primary progressive multiple sclerosis (MS) is a demyelinating autoimmune disease with only a single class of FDA-approved treatment, B cell depletion. Novel treatments could emerge from a deeper understanding of the interplay between multiple cell types within diseased tissue throughout progression. We initially describe an engineered biomaterial-based immunological niche (IN) as a surrogate for diseased tissue to investigate immune cell function and phenotype dynamics throughout a chronic progressive mouse model of MS. Using these niches, we identify an array of dysregulated CC chemokine signaling as potential targets. We then develop antigen-loaded nanoparticles that reduce CC chemokine signaling, while delivering antigen. These nanoparticles serve as an antigen-specific treatment, and
