Mitochondria are known to provide energy for our cells, but they also play an important role in the defense against pathogens. They can trigger immune responses and deprive pathogens of the nutrients they need to grow. A research team led by the Max Planck Institute for Biology of Aging in Cologne, Germany, has now shown that pathogens can turn off mitochondrial defense mechanisms by disabling a normal cellular response to stress. Scientists from the University of Bonn were also involved in the study, which was published in the journal Science.

The next science rally for children and young people aged 13 and over will take place on Saturday, January 29, 2022. Registration for the format "Science rally around Poppelsdorf digital" is possible up to and including Wednesday, January 26, 2022. On the day of the rally, science-loving participants will be welcomed at 10:00 a.m. in the Zoom webinar. Eleven virtual stations will then be open until 2:00 pm.

Long before the onset of dementia, there are signs of increased activity of the brain's immune system. Researchers at the DZNE and the University of Bonn have come to this conclusion based on a study of more than 1,000 older adults. Various proteins were recorded in the cerebrospinal fluid for this purpose: They served as so-called biomarkers that indicate inflammatory processes of the nervous system. As it turned out, some of these molecules are apparently part of an immune system damage limitation program - which could be useful for the development of new drugs. The study results have been published in the scientific journal "Neuron".
