Detail Information

Integrins are transmembrane cell surface receptors which mediate signal transduction, cell-to-cell interaction and cell-to extracellular matrix adhesion, key processes involved in angiogenesis, tumorigenesis and metastasis. Integrins have thus been hailed as clinically-relevant biomarkers of pathological conditions such as inflammation and tumor progression. The integrin avb3 is significantly upregulated in tumor cells and activated endothelial cells during neoangiogenesis. 

IntegriSense™ 645 fluorescent imaging agent is used for in vivo detection of avb3 using a low molecular weight peptidomimetic antagonist coupled to a red fluorochrome. IntegriSense 645, an integrin-targeted molecular imaging agent allows the non-invasive imaging of disease status and progression. Pairing of an integrin antagonist treatment with IntegriSense 645 provides a mechanistic biomarker approach for assessing target coverage.

Application Note

In Vivo Imaging of Atherosclerosis Disease Using FMT

Current means of measuring disease in preclinical models of atherosclerosis include ex vivo assessment of disease tissues post-mortem and non-invasive imaging primarily of structural and anatomic features of lesions, in vivo. A non-invasive, quantitative means of imaging known biologic profiles associated with atherosclerotic disease, in vivo, would enable a robust additional understanding and analysis of disease progression and therapeutic response in research and drug development. We report the utility of the near infrared (NIR) protease-sensing, ProSense® 750 Fluorescent Pre-clinical Imaging Agent, in combination with the FMT® 2500 Quantitative Pre-clinical Imaging System for the non-invasive quantitative measurement of atherosclerotic disease biology and related response to therapy in apolipoprotein (apo) E-deficient mice in vivo. FMT (Fluorescence Molecular Tomography) imaging measured significant increases in aortic region protease activity with a range of values that were comparable to the range seen in the ex vivo aortic arches assessed by fluorescence reflectance imaging (FRI).
