  • Publication number: 20240165279
    Abstract: Excessive deposition of extracellular matrix is a hallmark of Idiopathic pulmonary fibrosis (IPF); it is advantageous to target the cells and the mechanisms associated with this process. By targeting myofibroblasts (specialized contractile fibroblasts) that are key for the development of IPF with drugs conjugated with fibroblast activation protein (FAP), this technology helps minimize the production of extracellular matrix in the lungs and provides a new treatment option for patients diagnosed with IPF.
