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".

New insights into the human immune defense against poxviruses

—An international research team involving Bonn scientist has made an important contribution to understanding the human immune response to poxviruses: The scientists were able to show for the first time that different human cell types recognize poxviruses via different sensors in order to trigger inflammatory responses. At the same time, the team developed the world's first nanobodies that can specifically block the DNA sensor AIM2 – a tool that opens up new possibilities for inflammation and infection research. The paper has now been published in The EMBO Journal.

Multiple Sclerosis: Potential biomarker linked to progression and brain inflammation identified

—Better ways to detect ongoing brain damage in multiple sclerosis (MS) are urgently needed. An international team of scientists, including ImmunoSensation³ member Prof. Anne-Katrin Pröbstel, has identified a molecular circuit that drives brain injury in MS. In a mouse model, blocking the enzyme Bruton's tyrosine kinase prevented harmful clustering of immune cell and brain tissue demage. Patient data revealed the same immune signaling pattern, suggesting strong translational potential for diagnosis. The study was recently published in Nature Immunology.

Instructions for building antibodies decoded

—MOG Antibody-associated Disease (MOGAD) is a rare autoimmune disease of the central nervous system. The blood of patients contains antibodies against myelin oligodendrocyte glycoprotein (MOG), a protein in the myelin layer that surrounds the neurons in the brain. It is believed that these antibodies contribute to the destruction of this protective layer in the brain. Researchers at the University Hospital Bonn (UKB) and the Universities of Basel and Bonn, in collaboration with an international team, have now deciphered the construction plan of the anti-MOG antibodies.
