Suppressive DNA vaccination in Experimental Autoimmune Encephalomyelitis and how it affects gene expression of inflammatory mediatorsJakobsson, Charlotta January 2007 (has links)
<p>Vaccination with DNA encoding the encephalitogenic autoantigen myelin oligodendrocyte glycoprotein (MOG), pMOG91-108, induce a protective immunity against experimental autoimmune encephalomyelitis (EAE), an animal model of human multiple sclerosis. By injection of a DNA vaccine that contains a DNA region encoding short interfering RNA specific for IFNβ (pMOG-IFNβ) the protective effect of the DNA vaccination is totally inhibited.

IL-6 and IFNγ mRNA expression after MOG stimulation in rats treated with pCI, a control vaccine was significantly higher compared to the group vaccinated with vaccine containing pMOG-IFNβ.
