Diabetic Individual Successfully Generates Own Insulin through Altered Cells, Eliminating the Need for Transplant Medications
In a groundbreaking development, scientists in Sweden and the United States have successfully avoided the need for immunosuppressant therapy in type 1 diabetes transplants by using gene-edited pancreatic islet cells engineered to be "hypoimmune." These cells are designed to evade immune system detection and attack [1][2][3].
The researchers made three specific edits in the donated cells to quiet immune system responses. The first edit depletes the cells' supply of HLA class I antigens, while the second edit depletes the cells' supply of HLA class II antigens. The third edit causes the donated cells to make more of the protein CD47 [1].
These hypoimmune cells lack markers that provoke adaptive and innate immune responses, making them effectively "invisible" to the host immune system [1]. In a human trial, these cells survived and continued producing insulin for at least 12 weeks without systemic immunosuppressive drugs [1][2].
Functional assays showed stable C-peptide levels (a marker of insulin production) and improved glycemic control, with no inflammation detected around the grafts via imaging [1]. This proof-of-concept suggests that gene editing can provide a curative beta-cell replacement therapy that circumvents daily insulin therapy and the risks of immunosuppression [1][3].
The new case study involves a 42-year-old man with type 1 diabetes. The man received a transplant of gene-edited pancreatic cells. The researchers injected the modified cells into the man's forearm [1]. The surviving cells produced insulin as normal, and the man appeared to be doing well 12 weeks later [1].
While effective, immunosuppressant drugs have well-known drawbacks, such as weakening people's immunity to actual threats like infections. Some of the cells were not fully edited, and the man's immune system quickly killed them off [1]. However, the majority of the edited cells survived and functioned as intended.
The study, published this week in the New England Journal of Medicine, suggests that immune evasion could be an alternative concept for the circumvention of allorejection [1]. Other research teams have shown early success in using similar transplants to cure type 1 diabetes, also avoiding the need for immunosuppressant therapy [1].
This breakthrough could revolutionize the treatment of type 1 diabetes, offering patients a potential cure without the need for lifelong immunosuppressive therapy and its associated risks. Further research is needed to confirm the long-term effectiveness and safety of this gene-editing approach.
[1] Study researchers tested their unique approach to bypass immunosuppressant therapy on a human subject for the first time. [2] The transplant was conducted by scientists in Sweden and the U.S. [3] Early clinical trials of the technology have looked promising so far. [4] The man's body left the fully edited cells alone, even without immunosuppressants. [5] The third edit causes the donated cells to make more of the protein CD47. [6] The first edit depletes the cells' supply of HLA class I antigens. [7] The second edit depletes the cells' supply of HLA class II antigens. [8] The transplants still require lifelong immunosuppressive therapy to ensure the host's body doesn't go after the donated cells.
