Study shows: Too much salt weakens the immune defense

Study by the University Hospital of Bonn shows: A diet rich in salt weakens the antibacterial immune defense

A high-salt diet is not only bad for one's blood pressure, but also for the immune system. This is the conclusion of a current study under the leadership of the University Hospital Bonn conducted by the Cluster member Prof. Christian Kurts.

Mice fed a high-salt diet were found to suffer from much more severe bacterial infections. Human volunteers who consumed an additional six grams of salt per day also showed pronounced immune deficiencies. This amount corresponds to the salt content of two fast food meals. The results are published in the journal "Science Translational Medicine". Five grams a day, no more: This is the maximum amount of salt that adults should consume according to the recommendations of the World Health Organization (WHO). It corresponds approximately to one level teaspoon. In reality, however, many Germans exceed this limit considerably: Figures from the Robert Koch Institute suggest that on average men consume ten, women more than eight grams a day.

Smartphones as Retinal Cameras: New Opportunities for Global Eye Care

—Smartphones could play an important role in the early detection of eye diseases, including in settings where specialized ophthalmic infrastructure is limited. An international team of experts led by the UKB and the University of Bonn has comprehensively reviewed the current global landscape of smartphone-based fundus imaging. The researchers highlight the technical and clinical possibilities that already exist today, identify the limitations of these methods, and outline the conditions that must be met so that smartphone-based retinal imaging can be more widely integrated into screening.

Microplastics Cause Fatty Liver Disease in Mice

—Microplastics appear capable of significantly impairing the function of phagocytes in the liver, at least in mice. In turn, this disrupts the metabolism of this vital organ and increases the build-up of fat inside it. These are the key findings from a joint German-Austrian study led by the University of Bonn, details of which have now been published in the journal “Nature Metabolism.”

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.
