Immunonanotherapeutics that provide IgG humoral response without T-cell antigen

The present invention provides compositions and systems for delivery of nanocarriers to cells of the immune system. The invention provides nanocarriers capable of stimulating an immune response in T cells and/or in B cells. The invention provides nanocarriers that comprise an immunofeature surface having a plurality of nicotine moieties. The invention provides pharmaceutical compositions comprising inventive nanocarriers. The present invention provides methods of designing, manufacturing, and using inventive nanocarriers and pharmaceutical compositions thereof. For example, the present invention nanocarriers capable of eliciting an immune response and the production of anti-nicotine antibodies.
