Abstract
A generally spherical growth factor sensitive vesicle bearing growth factor receptors (12) having chemical compounds (14) covalently cross-linked to their non-growth factor binding domains. The chemical compounds are capable of associating to form larger chemical compounds (16) capable of destabilizing the vesicle. Methods for treating growth factor-overexpressing neoplasms are disclosed.
Claims5
A growth factor sensitive vesicle, comprising:
- an external shell which defines a generally spherical closed body;
- said shell bearing at least two growth factor receptors having functional growth factor binding domains facing outside said shell, at least two of said growth factor receptors each having at least one non-growth factor binding domain covalently cross-linked to at least one chemical compound, at least two of said chemical compounds being capable of associating to form a chemical compound capable of destabilizing or permeabilizing said shell, permitting the release of the contents, if any, orginally enclosed within said shell.
