Abstract (en)

[origin: WO9608263A1] A composition for specific intracellular delivery of a chemical agent into a CR2 receptor-bearing cell comprises a CR2 receptor binding and endocytosis inducing ligand (CBEL) coupled to the chemical agent. The CBEL binds to the CR2 receptor and elicits endocytosis of the composition. Optionally, the composition can include a spacer, which can be either biodegradable or non-biodegradable, for coupling the CBEL to the chemical agent. Chemical agents can include cytotoxins, transforming nucleic acids, gene regulators, labels, antigens, drugs, and the like. The composition can further comprise a carrier such as a water soluble polymer, liposome, or particulate. Methods of using these compositions for delivering a chemical agent in vivo or in vitro are also disclosed.
