Local Lung Delivery Of Ginkgetin For Therapeutic Intervention In Lung Fibrosis, Cimone L. Richardson

Theses and Dissertations

Lung fibrosis (LF) is a progressive, irreversible pathological condition in the lungs that is ultimately fatal. Current drug treatments (nintedanib, pirfenidone, and nerandomilast) slow disease progression but cause significant systemic adverse effects due to oral administration. Transient receptor potential vanilloid 4 (TRPV4), a mechanosensitive ion channel, may play a role in LF progression and represent a novel anti-LF target. Ginkgetin (GKT), a natural biflavonoid, is a potent TRPV4 inhibitor with anti-inflammatory and antioxidative properties. Local lung delivery could achieve high local lung concentrations while minimizing systemic exposure. Accordingly, this project evaluates GKT's therapeutic intervention efficacy in LF via local lung …
