Abstract
The various embodiments provide a composition that provides local control over inflammation. The composition localizes the activities of the cytokine-neutralizing antibodies to the site of inflammation through covalent attachment to hydrophilic matrices. The various embodiments including a hydrophilic polymer, a ligand binding moiety covalently attached to the polymer, and optionally, a cellular adhesion peptide covalently attached to the polymer. The hydrophilic polymer may be a glycosaminoglycan such as hyaluronan. The cellular adhesion peptide may be a linear RGD peptide sequence covalently attached to the polymer. The ligand binding moiety may be a monoclonal antibody covalently attached to the polymer. The antibody may be selected from the group consisting of an anti-IL-1β, an anti-IL-6, an anti-TNF-α, and combinations thereof. The polymer functions as a substrate or matrix for cell migration and tissue regeneration. The RGD peptide functions to promote cellular proliferation, migration and attachment to the polymer. The monoclonal antibody functions to inhibit the inflammatory response.
