**Problem:** Heart cells that are defective (e.g. due to mutations) **Tenaya Solution:** Restore cell function by using viral vectors to deliver healthy copies of genes or other therapeutic payloads [[Tenaya Deep Dive]] Gene Therapy platform uses AAVs to deliver genes to specific cells in the heart to correct or compensate for functional defects. We have the ability to use both known AAV capsids as well as novel capsids identified through our internal capsid engineering capabilities to target cardiomyocytes, cardiac fibroblasts  or other cells important to the proper functioning of the heart. The product candidates arising from this platform are intended to overcome the shortcomings of traditional therapies that are not able to address the underlying problems that contribute to heart disease. We believe this platform has potentially broad utility for both genetic and non-genetic forms of heart disease.
