TLR8 Publication in Immunity

Until now, the immune sensor TLR8 has remained in the shadows of science. A research team led by members of the Cluster of Excellence ImmunoSensation from the University of Bonn - Eva Bartok and Gunther Hartmann - has now discovered how this sensor plays an important role in defending human cells against intruders. The enzymes RNaseT2 and RNase2 cut ribonucleic acids (RNAs) of bacteria into small fragments that are as characteristic as a thumbprint. Only then can TLR8 recognize the dangerous pathogens and initiate countermeasures. The results have now been published in the renowned journal "Immunity".

How obesity also affects the next generation

—Children born to obese mothers are at higher risk of developing metabolic disorders, even if they follow a healthy diet themselves. A new study from the group of Elvira Mass at the University of Bonn offers an explanation for this phenomenon. In obese mice, certain cells in the embryo’s liver are reprogrammed during pregnancy. This leads to long-term changes in the offspring’s metabolism. The researchers believe that these findings could also be relevant for humans. The study has now been published in the journal Nature.

Immune Cells Drive Congenital Paralysis Disease

—Patients with spastic paraplegia type 15 develop movement disorders during adolescence that may ultimately require the use of a wheelchair. In the early stages of this rare hereditary disease the brain appears to play a major role by over-activating the immune system, as shown by a recent study published in the Journal of Experimental Medicine. The study was led by researchers at the University of Bonn and the German Center for Neurodegenerative Diseases (DZNE). These findings could also be relevant for Alzheimer's disease and other neurodegenerative conditions.

New way to prevent duodenal cancer

—People with the hereditary disease familial adenomatous polyposis (FAP) have a greatly increased risk of developing a malignant tumor of the duodenum. Researchers at the University Hospital Bonn (UKB) and the Cluster of Excellence ImmunoSensation2 at the University of Bonn have now discovered a mechanism in the local immune system that can drive the development of cancer. They see this as a promising new approach to preventing duodenal carcinoma in people with FAP. The results have now been published in the journal "Nature Communications".
