Scientists reverse fibrosis in preclinical studies – Lung and Liver

The publication reports on a new target: a dopamine receptor. The authors found that the receptor is unique to lung and liver fibroblasts. Stimulating it blocks YAP and TAZ, reducing and reversing the growth and scar-forming abilities of fibroblasts. Stimulating the dopamine receptor in fibroblasts appeared to switch them from a matrix-depositing state that supports fibrosis to a matrix-degrading state that supports resolution or reversal of fibrosis. In lung and liver fibrosis models, the approach reversed the fibrotic process in these organs.
