New method identifies aggressive breast cancer

Aggressive forms of breast cancer often manipulate the immune response in their favor. This manipulation is revealed in humans by the same immunological "signature" as in mice. This is shown by a study carried out by scientists from the University of Bonn and memebers of the Cluster of Excellence ImmunoSensation together with Dutch colleagues. Their method makes it possible to obtain an indication of the prognosis of the disease using patients' tumor tissue. The results are published in the journal "Cell Reports".

New Findings on Immunotherapy for a Rare Brain Infection

Progressive multifocal leukoencephalopathy (PML) is a rare but very serious brain disease. It is caused by the reactivation of the widespread JC virus when the immune system is severely weakened. There is currently no targeted antiviral therapy available, which is why new treatment approaches are urgently needed. In recent years, so-called immune checkpoint inhibitors have been increasingly used; these “unlock” the immune system and reactivate the body’s own immune cells. The results were recently published in the journal JAMA Neurology.

What Makes Sea Urchin and Salmon Sperm Swim

A recent study by the Max Planck Institute for Multidisciplinary Sciences and the University of Bonn shows that pH plays a crucial role in sperm motility in sea urchins and salmon. A rise in pH activates the enzyme soluble adenylyl cyclase (sAC), which produces the messenger molecule cAMP and thereby regulates sperm movement. This mechanism may be widespread in many marine invertebrates and fish. The findings have now been published in the Journal Proceedings of the National Academy of Sciences.

Immune cells remember their location

A new AI-based method reconstructs spatial information about where immune cells were originally located in an organ, even after these cells have been removed from the tissue and analyzed individually. To accomplish this, Researchers at the University Hospital Bonn (UKB) and the University of Bonn use the transcriptome, i.e., the entirety of all messenger RNA transcripts produced by genes within a cell at a given time. The work has now been published in the journal Advanced Science and introduces the new MERLIN algorithm.
