Abstract:
Magnetic Resonance Imaging, usually based on 1 H as the magnetic nucleus, is an important diagnostic technique that is commonly used in hospitals for the diagnosis of disease. MRI allows for the non- invasive imaging of soft tissue with a superb spatial resolution. Magnetic Resonance Imaging based on 19 F instead of 1 H opens up new diagnostic possibilities. The 19 F nucleus has a high gyromagnetic ratio (40 MHz/T) and a natural isotopic abundance ratio of 100%. In the human body, 19 F containing structures are exclusively present in the form of solid salts in e.g. teeth and bones. As a consequence, the J2 relaxation times of the endogenous 19 F atoms are extremely short and the MR signal is hardly detectable, in other words, the lack of endogenous, 19 F-based structures with relatively high transverse relaxation times assures a very low background MR signal. Therefore, exogenous 19 F-based MRI contrast agents allow for "hot spot" imaging in a way similar to other techniques such as PET (positron emission tomography). As a useful extension of its diagnostic use, MRI is also proposed for the monitoring of the delivery of bio-active agents such as therapeutic or diagnostic agents. I.e., MRI can not only be used for treatment planning, but also to control local drug delivery under image guidance.
Abstract:
The invention relates to antibodies that are capable to bind the extracellular domain of integrin. Another object of the invention concerns the use of said antibodies for detecting integrins in archival formalin fixed paraffin embedded (FFPE) tissue. The invention also relates to methods for preparing monoclonal rabbit antibodies, wherein the immunogen is an insect expression culture-derived recombinant extracellular integrin domain, and another method for screening anti-integrin antibodies that discriminate between closest integrin homologues and that are especially suited for immunohistochemistry in FFPE material.

Abstract:
The invention relates to a combination therapy for the treatment of tumors and tumor metastases comprising administration of integrin ligands, preferably integrin antagonists, together with co-therapeutic agents or therapy forms that have synergistic efficacy when administered consecutively with said ligands, such as chemotherapeutic agents and or radiation therapy. The therapy results in a synergistic potential increase of the inhibition effect of each individual therapeutic on tumor cell proliferation, yielding more effective treatment than found by administering an individual component alone, concurrently or not in the dosage regime of the present invention.

The invention relates to a combination therapy for the treatment of tumors and tumor metastases comprising administration of integrin ligands, preferably integrin antagonists, together with co-therapeutic agents or therapy forms that have synergistic efficacy when administered together with said ligands, such as chemotherapeutic agents and/or radiation therapy, in isolated organ perfusion. The therapy results in a synergistic potential increase of the inhibition effect of each individual therapeutic on tumor cell proliferation, yielding more effective treatment than found by administering an individual component alone.
Abstract:
The methods described herein provide for ways of modulating, specifically inhibiting, integrin activation. The methods include identifying compounds such as naturally occurring and non-naturally occurring polypeptides and small molecules which bind to the βA domain of an integrin thus mimicking the contact betwen the CD loop with βA domain. Contacting the βA domain in this manner locks the integrin such that it is unable to be activated.

Abstract:
The invention relates to a combination therapy for the treatment of tumors and tumor metastases comprising administration of receptor tyrosine kinase antagonists/inhibitors, especially ErbB receptor antagonists, more preferably EGF receptor (Her 1) antagonists and anti-angiogenic agents, preferably integrin antagonists, optionally together with agents or therapy forms that have additive or synergistic efficacy when administered together with said combination of antagonists/inhibitors, such as chemotherapeutic agents and or radiation therapy. The therapy can result in a synergistic potential increase of the inhibition effect of each individual therapeutic on tumor cell proliferation, yielding more effective treatment than found by administering an individual component alone.
