Eta-1/Osteopontin-Deficient Mice Autoimmune Encephalomyelitis in Cutting Edge: Attenuated Experimental

The influence of the proinflammatory cytokine, osteopontin, on autoimmune demyelinating disease.

Multiple sclerosis is a demyelinating disease, characterized by inflammation in the brain and spinal cord, possibly due to autoimmunity. Large-scale sequencing of cDNA libraries, derived from plaques dissected from brains of patients with multiple sclerosis (MS), indicated an abundance of transcripts for osteopontin (OPN). Microarray analysis of spinal cords from rats paralyzed by experimental ...

Cutting edge: IL-21 is not essential for Th17 differentiation or experimental autoimmune encephalomyelitis.

Recent studies have suggested that IL-21 is a key factor in the development of IL-17-producing CD4 T cells (Th17) and that the induction of experimental autoimmune encephalomyelitis, which depends on mounting an efficient Th17 response, is reportedly impaired in the absence of IL-21 signaling. In this study, we provide supportive in vitro evidence that IL-21 can drive Th17 responses in conjunct...

SJL/J Mice Experimental Autoimmune Encephalomyelitis in Nitric Oxide Synthase Inhibits Induction of Cutting Edge: Antisense Knockdown of Inducible

Cutting edge: C3, a key component of complement activation, is not required for the development of myelin oligodendrocyte glycoprotein peptide-induced experimental autoimmune encephalomyelitis in mice.

Experimental autoimmune encephalomyelitis (EAE), an inflammatory demyelinating disease of the CNS, is regarded as an experimental model for multiple sclerosis. The complement has been implicated in the pathogenesis of multiple sclerosis. To clarify the role of C in mouse EAE, we immunized mice deficient in C3 (C3(-/-)) and their wild-type (C3(+/+)) littermates with myelin oligodendrocyte glycop...

Cutting edge: IL-23 cross-regulates IL-12 production in T cell-dependent experimental colitis.

Although IL-12 and IL-23 share the common p40 subunit, IL-23, rather than IL-12, seems to drive the pathogenesis of experimental autoimmune encephalomyelitis and arthritis, because IL-23/p19 knockout mice are protected from disease. In contrast, we describe in this study that newly created LacZ knockin mice deficient for IL-23 p19 were highly susceptible for the development of experimental T ce...
