Multiple sclerosis (MS) is an inflammatory, demyelinating disease of the central nervous system (CNS) characterized by blood-brain barrier (BBB) breakdown. Disruptions of BBB continuity result in an influx of activated T cells and monocytes, and could contribute to lesion formation in the CNS. Matrix metalloproteinases (MMP) are enzymes implicated in BBB(More)
Experimental autoimmune myasthenia gravis (EAMG) is an animal model for human myasthenia gravis (MG), characterized by an autoaggressive T-cell-dependent antibody-mediated immune response directed against the acetylcholine receptor (AChR) of the neuromuscular junction. Dendritic cells (DC) are unique antigen-presenting cells which control T- and B-cell(More)
Suppression of interleukin 12 (IL-12) production by dendritic cells (DCs) has been hypothesized to be a principal mechanism underlying the biological action of interferon (IFN)-beta used for treatment of multiple sclerosis (MS), a chronic inflammatory disease of the central nervous system with possible autoimmune origin. How IFN-beta interacts with DCs to(More)
Oligoclonal T cell expansions (TCE) are common in old humans and mice, but it is not known whether the T cell response to a specific antigen is more restricted in old vs. young animals. Herein, we describe an enhanced and prolonged response of tumor antigen-specific CD8 cells in old mice identified by K(d)/peptide tetramers and Vbeta10 staining. At the(More)
