IsySource is a pioneering biotechnology company focused on the development of circular RNA (circRNA) therapeutics. Founded in 2021 by Dr. Wang Zefeng, a leading expert in RNA biology, the company leverages a proprietary platform to engineer stable and long-acting circRNA molecules. Unlike linear mRNA, circRNA's closed-loop structure provides enhanced stability and resistance to degradation, potentially offering superior efficacy and duration of protein expression. IsySource's pipeline includes vaccines for infectious diseases and protein replacement therapies for rare diseases and oncology. The company is backed by prominent investors such as IDG Capital and Lilly Asia Ventures, positioning it as a key player in the emerging circRNA field.
