Title: Cd31 shed as molecular marker for inflammation imaging
IPC: C12N15/12
Filed: 2022-03-16
Abstract: PROBLEM TO BE SOLVED: To provide a reliable solution relating to imaging and diagnosis of an inflammatory condition. 
     SOLUTION: Provided is a CD31 shed  for use as a target in molecular imaging of an inflammatory condition. Administering a radiolabeled peptide P8RI as CD31 shed  ligand in different rat models of inflammation indeed showed that CD31 shed  is present on activated cells in a quantity allowing a detectable signal, whereas the noise signal corresponding to CD31 shed  present on activated circulating cells and on other organs or cells not involved in inflammation was little. The present invention thus also relates to a labeled CD31 shed  ligand and the use thereof as a molecular imaging agent in the molecular imaging of an inflammatory condition. The molecular imaging of inflammatory sites particularly allows determining whether a subject suffers from or is at risk of having an inflammatory condition or is at risk of recurrence of an inflammatory condition after an anti-inflammatory treatment.
