What does Joshua A Weiner research?

Joshua A Weiner studies how various factors influence the success and survival of patients after receiving intestinal transplants. He examines conditions that affect this type of transplant, analyzing data from past patients to determine what predicts longer survival. His work also involves research on how matching certain proteins, known as MHC class II, among transplant donors and recipients can lead to better acceptance of transplanted intestines. This research is particularly relevant for patients suffering from intestinal failure and their healthcare providers, as it guides treatment decisions and improves patient chances of a successful recovery.

Key findings

  • In a study of 567 intestinal transplant patients, older age and repeated infections before the transplant were associated with lower survival rates, while lower bilirubin levels were linked to a better chance of survival.
  • Matching MHC class II proteins in a study using pigs led to improved acceptance of transplanted intestines, indicating that partial matches can promote a beneficial immune response.
  • The research indicates that patients needing a simultaneous liver transplant with their intestinal transplant may face reduced survival odds.

This study focused on how ferret immune proteins called Fcγ receptors interact with different types of antibodies (IgG) from both ferrets and humans. Researchers found that ferret antibodies tended to bind more effectively to these receptors than human antibodies, which is important for understanding how immune responses work in ferrets. This research helps in improving vaccine development and treatment strategies that involve antibodies, especially for diseases affecting the respiratory system. Who this helps: Patients needing better vaccines and treatments for respiratory illnesses.

Science signaling

Man KNM, Rougé SLS, Berumen RA, Jacobi AA, Weiner JC +11 more

Plain English
This study looked at how dopamine, a brain chemical, affects working memory by influencing specific calcium channels in brain cells. Researchers found that when dopamine was activated, it increased the activity of a calcium channel called Ca1.2, which in turn improved spatial working memory in mice. Specifically, the improvement was observed in normal mice but not in those genetically modified to block this channel, indicating that Ca1.2 is essential for the memory-enhancing effects of dopamine. Who this helps: This benefits patients with memory-related conditions, such as those with ADHD or cognitive impairments.

Plain English
This study examined how a protein called vaspin affects fat cells and their role in burning energy, particularly when the body is cold or fasting. Researchers found that when vaspin levels were increased in mice, it decreased the activity of beneficial brown fat, leading to problems with temperature regulation. Specifically, higher vaspin reduced energy expenditure in cold conditions, which could contribute to issues like obesity and heart disease. Who this helps: This information benefits doctors and researchers working on obesity and metabolic disorders.

Hartung T, Freyer D, Zemella A, Radbruch H, Weiner J +3 more

Plain English
This research studied a version of a protein called erythropoietin (EPO) that is made in the human brain and helps protect brain cells. The researchers found that a specific variant, called hS3, is more active in certain brain diseases like stroke and inflammation, while it is less active in neurodegenerative diseases. They discovered that hS3 is better at protecting nerve cells than regular EPO, especially when combined with a small peptide called PD29, and could help develop new treatments for brain injuries and diseases. Who this helps: This helps patients with brain injuries and neurodegenerative diseases.

Plain English
This study looked at new ways to provide hearts for transplant when human donors are in short supply. Researchers found that genetically modified pig hearts could be successfully transplanted into baboons, and two patients who received these pig hearts survived for up to 2 months. Solving remaining challenges could allow patients to survive even longer, which would greatly increase the availability of hearts for transplantation. Who this helps: This benefits patients with end-stage heart failure who need a transplant.

Transplantation

Chauhan I, Llore NP, Hirakata A, Ishikawa Y, Vallabhajosyula P +4 more

Plain English
This study looked at how miniature pigs that received a combined islet and kidney transplant (called an islet-kidney graft) developed high blood sugar levels (hyperglycemia) as they grew. It found that all four pigs gained weight, which was linked to their increased blood sugar, but not because the islets were failing; rather, their bodies needed more insulin due to their growth. The results suggest that managing weight and insulin needs is crucial for the long-term success of this transplant method. Who this helps: This helps patients with type 1 diabetes who may benefit from islet-kidney transplants.

Transplantation

Gunes ME, Patwardhan S, Merl S, Yang K, Jones R +23 more

Plain English
This study looked at how matching specific proteins (called MHC class II) affects the success of intestinal transplants in pigs. The research found that when there was some matching of these proteins (out of a total of three different types), the pigs were able to accept the transplanted intestines better than when there was no matching; specifically, the partially matched pigs developed a unique type of tolerance that included protective immune cells. These results are important because they suggest that matching MHC class II proteins may help improve the success of intestinal transplants in humans. Who this helps: This helps patients needing intestinal transplants and their doctors.
