1. A method of reducing the severity of an autoimmune disorder, comprising identifying a subject suffering from an autoimmune disorder and administering to said subject a scaffold composition comprising an antigen, a recruitment composition, and a tolerogen,wherein said antigen is derived from a cell to which a pathologic autoimmune response associated with said disorder is directed;
- wherein said tolerogen induces immune tolerance or a reduction in an immune response;
wherein said tolerogen is selected from the group consisting of retinoic acid, rapamycin, aspirin, and vasoactive intestinal peptide; and
wherein the scaffold composition does not comprise IL-10, dexamethasone, vitamin D, or TGF-beta.

Abstract
Biomaterial systems, e.g., gel scaffolds, are used in vivo to recruit immune cells and promote their activation towards a non-inflammatory phenotype, thereby leading suppression of inflammation. The compositions and methods are useful to reduce the severity of autoimmunity, chronic inflammation, allergy, and periodontal disease.
