  • ANTIGENIC TRIPEPTIDES DERIVED FROM MYCOBACTERIUM AVIUM SUBSP. PARATUBERCULOSIS S-TYPE STRAINS, DERIVATIVES AND USES THEREOF
    Publication number: 20230046953
    Abstract: The present invention is directed to an isolated synthetic tripeptide of formula H-D-Phe-N-Methyl-L-Val-L-Ala-OMe (SEQ ID NO:1), or a derivative thereof, and to the corresponding lipotripeptides, which are specific to Mycobacterium avium subsp. paratuberculosis (Map)S-type strain, as well as derivatives and conjugates thereof. The invention also concerns the use of these antigens in different methods and tests for detecting Map infection, especially by detecting humoral response and cell mediated response of infected animals.

  • CD31SHED AS A MOLECULAR TARGET FOR IMAGING OF INFLAMMATION
    Publication number: 20210347890
    Abstract: Disclosed is CD31shed for use as a molecular imaging target in the molecular imaging of an inflammatory condition. Administering the radiolabeled peptide P8RI as CD31shed ligand in different rat models of inflammation indeed showed that CD31shed is present on activated cells in a quantity allowing a detectable signal, whereas the noise signal corresponding to CD31shed present on activated circulating cells and on other organs or cells not involved in inflammation was little. Also disclosed is a labeled CD31shed 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.
