  • Patent number: 11820833
    Abstract: An isolated peptide of up to 6 amino acids comprising an amino acid sequence which inhibits binding of an endothelial cell protein C receptor (EPCR) ligand to the EPCR is disclosed. Also disclosed is an isolated peptide comprising an amino acid sequence which inhibits binding of an endothelial cell protein C receptor (EPCR) ligand to the EPCR, wherein the peptide comprises a modification in at least one amino acid. Also disclosed is a molecule comprising an amino acid sequence which inhibits binding of an endothelial cell protein C receptor (EPCR) ligand to the EPCR attached to a heterologous moiety. Pharmaceutical compositions and methods of treatment are also disclosed.
