    Dr. Ling Yin is a pioneer in gene therapy, and through her advancements in the use of adeno-associated viruses (AAV), she has revolutionized treatments for genetic disorders and beyond. Her groundbreaking work redefines possibilities in gene therapy and inspires a new era of medicine that could change lives.

    Born in Shandong, China, Dr. Yin always wanted to explore and understand the world, which science allowed her to do.

    “When I first encountered science, I realized it was an art—a process of creativity, revolution and adventure,” Dr. Yin explains. “It fascinated me how science could challenge old norms and create new possibilities. This sense of innovation resonated deeply with me.”

    She began her academic journey in agriculture, particularly interested in the growing global population and its impact on food security. Crop breeding for quantity became her area of interest, which led to improving food quality. Her exploration of this space led to a Bachelor of Science in seed science and engineering and a Master of Science in vegetable genetics and breeding.

    From 2013 to 2016, Dr. Yin attended South China Agricultural University for her Doctor of Philosophy in vegetable genetics and breeding. While working on vegetable breeding of Chinese kale, she focused on its potential to produce anticancer materials.

    This bridging of agriculture and medicine inspired her to pursue medical science. In 2017 she moved to the U.S. to explore this space and began studying virology, gene therapy, and working with AAVs.

    “AAV is a game-changer in gene therapy,” says Dr. Yin. “Its unique ability to deliver genetic material into cells with precision and minimal immune response makes it an ideal tool for treating a wide range of diseases.”

    Dr. Yin’s expertise lies in developing innovative AAV-based platforms that push the boundaries of what’s possible in modern medicine. Her research focuses on optimizing AAV’s safety, efficacy, and adaptability, unlocking its potential to target diseases once deemed untreatable.

    A Visionary Approach to AAV Technology

    Dr. Yin’s holistic approach to AAV research combines molecular biology, virology and advanced computational techniques.

    This unique approach addresses critical challenges in the field, such as overcoming immune resistance, enhancing gene delivery efficiency, and expanding the range of tissues and conditions AAV can target.

    “The versatility of AAV is incredible,” Dr. Yin explains. “It’s like a delivery system that can be tailored to specific destinations in the body. Our job as researchers is to refine this system to ensure it’s as effective and safe as possible.”

    Dr. Yin has been at the forefront of designing next-generation AAV vectors capable of addressing complex genetic diseases, including muscular dystrophy, haemophilia, and certain neurodegenerative disorders. Her contributions include the development of engineered capsids—the protein shells of AAV—that enhance the virus’s ability to navigate the human body and deliver therapeutic genes precisely where they’re needed.

    This much-needed research was recognized by the Nobel Prize in Physiology or Medicine this year. It was awarded jointly to Victor Ambros and Gary Ruvkun “for discovering microRNA and its role in post-transcriptional gene regulation.”

    Arun Srivastava, Ph.D., is a professor in the division of Cellular and Molecular Therapy at the University of Florida. He worked with Dr. Yin in his laboratory to advance the use of AAVs.

    In two studies involving AAV3 and AAV6 serotypes, Dr. Yin found potential gene therapies for both liver cancer and blood disorders through the delivery of two microRNAs (miR-26a and miR-122).

    “The combined use of miR-26a and miR-122 delivered by AAV3 vectors offers a potentially useful way to target human liver tumors, and shows her ability to combine cutting-edge AAV virology with cancer biology,” Dr. Srivastava explains.

    During these studies, Dr. Yin also worked with Geoffrey D. Keeler, Ph.D., a research assistant professor at UF. For him, her development of the AAV3 vectors was a novel approach.

    “It showcases Dr. Yin’s ability to dissect complex problems in very difficult fields such as cancer biology and develop new approaches that are effective,” Dr. Keeler explains. “This is not a trait often seen. In fact, more often than not this trait is missing from individuals ‘toolbox’.”

    Dr. Chen Ling, Ph.D. is a professor at Fudan University’s School of Life Sciences in the genetics department. He sees Dr. Yin as a leading figure in gene therapy, particularly in optimizing AAV vectors for therapeutic applications .

    “Her innovative research transforms the treatment of genetic disorders by directly addressing underlying DNA mutations,” explains Dr. Ling. “With the anticipated approval of up to 17 new gene therapies by regulatory agencies in 2024, Dr. Yin’s work aligns perfectly with this rapidly evolving field.”

    As one of her several proposed research endeavors, Dr. Yin’s AAV findings are intended to have a future impact on the U.S. healthcare system in several ways.

    While effective, gene therapy could cost the U.S. $25 billion by 2034. Dr. Yin’s research aims also to reduce treatment costs through a long-term outlook.

    Making therapy cheaper and faster to produce creates greater accessibility to treatment and improved health outcomes, which reduces healthcare expenditures over time.

    AAV also offers a safe, efficient way to address diseases at the genetic level with fewer patient side effects. Her research aligns with the U.S. government’s priorities in personalized medicine, biotechnology and healthcare innovation.

    Dr. Yin has written a peer-reviewed manuscript entitled: ‘Enhanced Transduction of Human Hematopoietic Stem Cells by AAV6 Vectors: Implications in Gene Therapy and Genome Editing.’
