To prevent an organism from developing autoimmunity the body limits the number of autoreactive cells through thymic negative selection and regulates their activity through induction of suppressor T cells.
Development of antigen-specific therapies provides an interesting opportunity to imitate the body's own, often effective, method of protection.
Our study demonstrates that DBA/1 mice could be protected from experimental autoimmune encephalomyelitis induced through injection of recombinant myelin oligodendrocyte glycoprotein (rMOG) when they were previously immunized intraperitoneally with rMOG adsorbed to aluminium hydroxide.
This protection was associated with a decreased IFN-gamma production by rMOG-specific cells, but not a decreased proliferative response.
Protection was long lasting, indicating that MOG-alum vaccination might be developed as a prophylactic therapy in multiple sclerosis.
