The present invention is related to compositions and methods to stimulate the immune system. For example, antigen-specific antibodies may be produced by stimulating B cell populations with specific antigenic compounds, such as an adjuvant comprising a macromolecule capable of activating a Toll-Like receptor (TLR). For example, a BCR adapter IgM (BCRAM) is described to exemplify delivery of autoantigens to polyclonal B cell populations resulting in immunoactivation by TLR activation. Alternatively, a compound is described that inhibits TLR activation.
