title = "The IgM Response to Modified LDL in Experimental Atherosclerosis Hypochlorite-modified LDL IgM Antibodies versus Classical Natural T15 IgM Antibodies",
abstract = "Introduction: It is hypothesized that IgM antibodies to oxidized LDL are anti-atherogenic. Myeloperoxidase from plaque-infiltrating neutrophils catalyzes the production of hypochlorite (HOCl), which oxidizes LDL. Here we study the IgM response to HOCl-modified LDL in comparison to titers of T15 clonotypic natural antibodies. Methods: Plasma of LDLR-/- mice fed a normal chow or high-fat diet was obtained after 6 and 16 weeks. The IgM responses to HOCl-modified LDL and T15 clonotypic natural IgM antibodies were measured by ELISA. Results: The IgM levels in response to HOCl-modified LDL increased dramatically in the atherosclerotic group after introduction of the high-fat diet, but not in mice on normal chow. The natural IgM T15 clonotypic antibody titers revealed a more moderate increase during atherogenesis. Conclusion: Our results show that during atherogenesis there is a strong induction of IgM antibodies to HOCl-modified LDL particles. Whether these induced IgM antibodies are pro- or anti-atherogenic remains to be established.",
