Abstract

The potential of lipopolysaccharide (LPS) to induce antigen-specific B cell responses to acetylcholine receptor (AChR) in myasthenia gravis (MG) was evaluated in wild type (WT) and CD4-/- C57BL/6 mice. The WT mice immunized with AChR in LPS developed an MG-like disease (LPS-EAMG) similar to that induced by immunization with AChR in complete Freund's adjuvant (CFA-EAMG). CD4-/- mice were resistant to CFA-EAMG but susceptible to LPS-EAMG. LPS abrogated EAMG resistance in CD4-/- mice by increasing high-affinity anti-AChR IgG2b in sera and enhancing immune complex deposition in muscle.
