Abstract

B cells have limited endocytic capacity and are reported to endocytose and present liposome-encapsulated antigens poorly. B cells also endocytose soluble antigens poorly, except those for which their surface immunoglobulin is specific, which are taken up and presented efficiently. We present results indicating that, in vitro, B cells endocytose small liposomes bearing antigen with affinity for their surface immunoglobulin. Antigen encapsulated in liposomes targeted by antibody specific for surface immunoglobulin is presented to T cells as efficiently as specific antigen in soluble form. These studies provide a rational basis for the design of liposomes optimized to stimulate T-dependent B-cell responses.
