Medical science has not yet been able to explain why the Epstein-Barr virus triggers infectious mononucleosis (IM) in some people with initial infections and not in others. But now, a research team led by Elisabeth Puchhammer-Stöckl, head of the Center for Virology at MedUni Vienna, has identified a specific immune response to the virus as the cause, and as a potential target for the development of vaccines. The findings were recently published in the American Society of Hematology’s journal Blood.

Proliferation of the Epstein-Barr virus (EBV) in humans is normally combated by T cells as part of an antiviral immune response. By means of this important mechanism, certain EBV components (peptides) are presented to the T cells by a specific1LA-E molecules on EBV-infected cells.

University of Queensland researchers have identified a pathway in cells that could be used to reprogram the body’s immune system to fight back against both chronic inflammatory and infectious diseases.

Dr. Kaustav Das Gupta and Professor Matt Sweet from UQ’s Institute for Molecular Bioscience discovered that a molecule derived from glucose in immune cells can both stop bacteria growing and dampen inflammatory responses. Dr. Das Gupta said that the finding is a critical step towards future therapeutics that train immune cells.

The research was published in Proceedings of the National Academy of Sciences (PNAS).

“The effects of this molecule called ribulose-5-phosphate on bacteria are striking—it can cooperate with other immune factors to stop dise...

Many genetic diseases are caused by diverse mutations spread across an entire gene, and designing genome editing approaches for each patient’s mutation would be impractical and costly.

Investigators at Massachusetts General Hospital (MGH) recently developed an optimized method that improves the accuracy of inserting large DNA segments into a genome.

This approach could be used to insert a whole normal or “wild-type” replacement gene, which could act as a blanket therapy for a disease irrespective of a patient’s particular mutation.

The work involves the optimization of a new class of technologies...
