Claims
- 1. Compositions for detecting and treating vulnerable plaque, said compositions comprising:
a binding molecule which specifically binds to markers on stressed or apoptotic cells which are characteristic of vulnerable plaque; a targeting molecule coupled to the binding molecule which permits localization of the composition when intravascularly bound to vulnerable plaque; and an effector molecule coupled to the binding molecule which selectively kills or inhibits the stressed or apoptotic cells.
- 2. Compositions as in claim 1, wherein the binding molecule comprises an annexin.
- 3. Compositions as in claims 1 and 2, wherein the targeting molecule composes a radiolabel such as technetium-99m.
- 4. Compositions as in claims 1-3, wherein the effector molecule comprises a photodynamic agent such as a porphyrin.
- 5. Compositions for detecting and treating vulnerable plaque, said compositions comprising:
an annexin; and a targeting molecule coupled to the annexin which permits localization of the composition when intravascularly bound to vulnerable plaque.
- 6. Compositions as in claim 5 wherein the annexin is annexin V.
- 7. Compositions as in claim 5 or 6, wherein the targeting molecule comprises a radiolabel such as technetium-99m.
- 8. A method for detecting and treating vulnerable plaque, said method comprising:
administering a composition to a patient suspected of having vulnerable plaque, said composition being capable of specifically binding to the vulnerable plaque, being localized when bound, and killing or inhibiting the apoptotic or stressed cells characteristic of vulnerable plaque; determining whether the composition has localized within the vasculature, and activating the composition to kill or inhibit the apoptotic or stressed cells the composition has localized.
- 9. A method as in claim 8, wherein the composition further comprises a photodynamic agent such as a porphyrin.
- 10. A method as in claim 8, wherein activating comprises photodynamic activation.
