Hair loss gene discovery

Hairlessness, skin changes, a strong hypersensitivity to light: these are the symptoms of the so-called IFAP syndrome. Scientists from the universities of Beijing, Hamburg and Bonn have now identified a genetic defect that triggers the rare disorder. The results have been published in the "American Journal of Human Genetics". IFAP syndrome is very rare; Probably not even 100 people in Germany suffer from this congenital disorder. Those affected are sparsely hairy to complete hairlessness, even eyebrows and eyelashes may be missing. The skin is often keratinized; Sunlight or strong artificial light hurts the eyes. The abbreviation "IFAP" stands for the medical names of these three key symptoms.

In the medium term, the study could also open up new ways of treating IFAP syndrome. Perhaps, for example, the lack of cholesterol in the skin can be improved by special fatty ointments. However, further studies have to show whether this really works. The results already provide an insight into the diverse processes that must work together for the healthy development of skin and hair.

Study reveals dynamic interactions between brain tumors and immune cells

—Glioblastoma, the most common and aggressive brain tumor in adults, is difficult to treat because this cancer can invade the surrounding brain tissue and spread far beyond the original tumor mass. Researchers from the DZNE, the University Hospital Bonn (UKB), and ImmunoSensation³ at the University of Bonn have observed this infiltration process in the living brain using high-tech microscopy. Their study is based on research in mice with a form of brain tumor that closely resembles human glioblastoma.

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.
