Cardiac fibrosis is the final common pathology in heart disease. Here we establish an integrated imaging-genomic discovery platform using primary human heart fibroblasts to identify new drug targets for cardiac fibrosis. Genome wide analyses identify IL11, a secreted cytokine amenable to therapeutic inhibition, as the leading pro-fibrotic candidate. We demonstrate an autocrine loop of IL11 activity that is critical for fibrosis and acts as a nexus of signalling convergence for multiple pro-fibrotic stimuli. IL11 signals in cis and trans via the ERK cascade to activate a programme of fibrosis primarily at the level of protein translation. Injection of IL11 to mice causes fibrosis of the heart, kidney, lung, skin and liver whereas genetic ablation of the IL11 receptor prevented fibrosis across tissues. These data define a new non-canonical fibrogenic pathway and prioritise IL11 as a novel therapeutic target for fibrosis of the heart and other organs SOURCE: Sonia Chothani (e0081753@u.duke.nus.edu) - Prof. Stuart Cook Duke-NUS school of medicine
