Inflammatory Processes Drive Progression of Alzheimer's and Other Brain Diseases

Report in "Nature" Inflammation drives the progression of neurodegenerative brain diseases and plays a major role in the accumulation of tau proteins within neurons. An international research team led by Prof. Michael Heneka (DZNE), member of cluster of excellence ImmunoSensation, and the University of Bonn comes to this conclusion in the journal "Nature". The findings are based on the analyses of human brain tissue and further lab studies. In the particular case of Alzheimer's the results reveal a hitherto unknown connection between Abeta and tau pathology. Furthermore, the results indicate that inflammatory processes represent a potential target for future therapies. ies.

Decoding the Effects of Obesity

—A group of innate immune cells known as group 2 innate lymphoid cells (ILC2s) are essential for maintaining a healthy metabolic balance in adipose tissue. Obesity significantly impairs the number and function of ILC2s. How ILC2s are disrupted by obesity has so far remained unclear. Researchers from the UKB and the University of Bonn have now shown in obese mice that acetyl-CoA carboxylase 1, a key enzyme in fatty acid biosynthesis, is a crucial regulator of the maintenance and function of ILC2 immune cells in adipose tissue. The results have now been published in the journal Cell Metabolism.

As Temperatures Fall, so does the Risk of Malaria Transmission

—The good news comes with autumn: As temperatures fall, the risk of further malaria transmission in Germany also decreases significantly. However, the current cases reported in the vicinity of Frankfurt Airport show that, in very rare cases, malaria can occur in Germany even without previous travel abroad. In such cases, early diagnosis is crucial.

New Findings on Information Processing in the Brain

—Neurons receive thousands of signals via tree-like extensions called dendrites. Until now, these dendrites were thought to be relatively smooth cables that conduct electrical signals to the cell body. Using various advanced microscopy techniques, an international research team has identified tiny, previously overlooked constrictions along the dendrites. The study results have now been published in the journal Science Advances.
