Abstract:
Disclosed are methods and compositions wherein opsonin-enhanced cells, that is, cells which have been 1) modified so as to express an opsonin from a recombinant nucleic acid, 2) modified so as to express higher levels of an endogenous opsonin, or 3) mixed with an exogenous opsonin, when administered to a subject, modulate the immune response in the recipient to a selected antigen or antigens contained in or attached to the cells.
