COMPOSITIONS AND METHODS FOR PREVENTING OR TREATING CHRONIC LUNG ALLOGRAFT DYSFUNCTION AND IDIOPATHIC PULMONARY FIBROSIS

摘要

The described invention provides compositions and methods for reducing lung allograft dysfunction after lung transplant and for treating a severe pulmonary fibrosis characterized by aberrant fibroblast proliferation and extracellular matrix deposition in a tissue of a subject. The methods comprise administering to a subject in need thereof a composition comprising an antibody component comprising a therapeutic amount of an anti-CD44 antibody; and an MK2 inhibitor component comprising a therapeutic amount of an MK2 inhibitor (MK2i) polypeptide of amino acid sequence YARAAARQARAKALARQLGVAA (SEQ ID NO: 1) or at least one peptide functionally equivalent to the therapeutic domain thereof selected from a polypeptide of amino acid sequence KALARQLAVA (SEQ ID NO: 8), a polypeptide of amino acid sequence KALARQLGVA (SEQ ID NO: 9) and a polypeptide of aminoacid sequence KALARQLGVAA (SEQ ID NO: 1), or a functional equivalent thereof, and a pharmaceutically acceptable carrier.
