The invention provides compositions and methods for increasing the levels of an autoantigen-specific IgM antibody in a mammal and, thus, decreasing the levels of a circulating autoantigen in a mammal. Using these autoantigen-specific IgM antibodies, the invention provides compositions and methods for ameliorating an autoimmune disease in a mammal. In one aspect, the invention provides compositions and methods for increasing the levels of an antigen-specific IgG antibody in a mammal and, thus, decreasing the levels of a circulating antigen in a mammal. Using these antigen-specific IgG antibodies, the invention provides compositions and methods for ameliorating a disease or condition in a mammal, e.g., a cancer or a foreign antigen, such as a pathogen.
