Two items relevant to long COVID

One of the tricky issues in studying in long COVID is: how widely do researchers cast their net? Initial reports acknowledged that people who were hospitalized and in intensive care may take a while to get back on their feet. But the number of people who had SARS-CoV-2 infections and were NOT hospitalized, yet experienced lingering symptoms, may be greater. A recent report from the United Kingdom, published in PLOS Medicine, studied more than Read more

Signature of success for an HIV vaccine?

Efforts to produce a vaccine against HIV/AIDS have been sustained for more than a decade by a single, modest success: the RV144 clinical trial in Thailand, whose results were reported in 2009. Now Emory, Harvard and Case Western Reserve scientists have identified a gene activity signature that may explain why the vaccine regimen in the RV144 study was protective in some individuals, while other HIV vaccine studies were not successful. The researchers think that this signature, Read more

Challenges in islet transplantation

Two recent research papers from the Emory Transplant Center describe research on pancreatic islet transplantation, an experimental procedure that could help people with type I diabetes live without daily insulin injections.

Islet transplantation may offer people with type I diabetes the ability to produce their own insulin again

As with other types of transplantation, the challenge with islet transplantation is to avoid rejection of the donated organ and to balance that goal against side effects from the drugs needed to control the immune system. These papers illustrate how that balancing act is especially complex.

In the last decade, transplant specialists developed a method for islet transplantation named the “Edmonton protocol” after pioneers at the University of Alberta. While the emergence of this method was a major step forward, there are limitations:
