Abstract
A complete prevention of clinical experimental autoimmune myasthenia gravis (EAMG) was observed in lymphotoxin (LT)-α deficient (LT-α-/-) mice compared to LT-α+/+ mice when immunized with acetylcholine receptor. However, only a partial prevention of clinical EAMG incidence was observed in LT-β-/- mice compared to LT-β+/+ mice. LT-α-/- and LT-β-/- mice had lower mean titers of total IgG, IgG1, IgG2a and IgG2b and higher or equal mean titers of IgM anti-AChR antibodies compared to controls. Therefore, LT-α-/- and LT-β-/- AChR immunized mice are capable of mounting a primary (IgM) humoral immune response to AChR, but are less capable of switching to the pathogenic anti-AChR IgG isotypes. LT could play a significant role in the pathogenesis of myasthenia gravis.
