  • Publication number: 20240148912
    Abstract: The present disclosure provides activatable and detectable membrane-interacting peptides that, following activation, can interact with phospholipid bilayers, such as cell membranes. The present disclosure also provides methods of use of such compounds. The compounds of the present disclosure are of the general structure X1a-A-X2-Z-X1b, where A is a membrane-interacting peptide region having a plurality of nonpolar hydrophobic amino acid residues that, following separation from portions Z, is capable of interaction with a phospholipid bilayer; Z is an inhibitory peptide region that can inhibit the activity of portion A; X2 is a cleavable linker that can be cleaved to release cleavage products from the compound; and X1a and X1b are optionally-present chemical handles that facilitate conjugation of various cargo moieties to the compound. Prior to cleavage of the composition at X2, the composition acts as a promolecule that does not associate with cellular membranes to a significant or detectable level.

  • Publication number: 20220381784
    Abstract: Diagnostic platforms for the detection of mucinous and high grade cysts in the pancreas of subjects are provided. The disclosure provides a system comprising enzyme specific substrate, that are specific for detection and/or quantification of serine protease TPP-1, the value of which corresponding to a determination of whether a mucinous cyst in the pancreas is malignant or benign. The disclosure also provides for a two-step method, in which a sample from a pancreatic cyst is determined mucinous by detection and/or quantification of aspartyl protease expression, and then the same cyst is determined high grade dysplasia or malignant by detection and/or quantification of serine protease expression.

  • Patent number: 10239954
    Abstract: The present disclosure relates to antibodies specific for urokinase-type plasminogen activator (uPA). According to certain embodiments, the anti-uPA antibody specifically binds to the active form of uPA. In certain aspects, the anti-uPA antibody that specifically binds to active uPA binds specifically to the active form of human uPA (e.g., the antibody does not cross-react with active forms of uPA from non-human organisms). In certain aspects, an anti-uPA antibody of the present disclosure competes for specific binding to uPA with plasminogen activator inhibitor type 1 (PAI-1), where binding of the antibody to uPA results in internalization of a complex that includes the antibody, uPA, and urokinase-type plasminogen activator receptor (uPAR). Also provided are antibodies that specifically bind to uPA and compete for binding to uPA with a synthetic ligand of uPA. The disclosure also provides anti-uPA antibody conjugates and compositions (e.g.
