Sperm are masters of tetris packing
Sperm are masters of tetris packing
Study sheds light on the process that plays a central role During sperm production, an enormous amount of DNA has to be packed into a very small space without breaking anything. A central role is played by certain proteins around which the DNA thread is wrapped - the protamines. A recent study by the University of Bonn provides new insights into this important mechanism.

Inflammatory response in blood driving factor
Inflammatory response in blood driving factor
What factors influence the life expectancy of patients with advanced gastric cancer? Scientists at Leipzig University Hospital have discovered that the body's inflammatory response is accompanied by reduced muscle quality in patients and ultimately constitutes the decisive factor for the prognosis. Their results have been published in the -Annals of Oncology-.

Molecules boosting plant immunity identified
Researchers identify two classes of molecules that control immune responses in plants / Publication in Science Two studies published in the journal Science by researchers at the Max Planck Institute for Plant Breeding Research in Cologne, Germany in collaboration with colleagues in China have discovered natural cellular molecules that drive critical plant immune responses.

Molecule boosts fat burning
Molecule boosts fat burning
Study identifies a new signaling molecule that increases the energy consumption of brown fat cells A study led by the University of Bonn and the University Hospital Bonn has identified a molecule - the purine inosine - that boosts fat burning in brown adipocytes. The mechanism was discovered in mice, but probably exists in humans as well: If a transporter for inosine is less active, the mice remain significantly leaner despite a high-fat diet.

Lung cancer: When radiation does not work
Lung cancer: When radiation does not work
Some lung tumors do not respond to radiation therapy. This effect can be reversed by blocking an enzyme in the tumor cells, as a Würzburg research team reports. Lung cancer is the most common cancer in the world, with 2.2 million new cases and around 1.8 million deaths in 2020 alone. While knowledge about the disease has improved considerably and new therapeutic strategies can prolong the lives of previously incurable patients, the figures clearly show that the mortality rate is still far too high.

A step on the way to better therapies against viruses
A step on the way to better therapies against viruses
Researchers from the MHH and RESIST show how a cell protein of the innate immune response prevents the multiplication of herpes viruses Most body cells can defend themselves against viruses after they have been activated by the body's own messenger substances (interferons). This happens with the help of proteins that recognise invading virus components and interfere with virus replication.

Smoking promotes development of severe pulmonary hypertension
Smoking promotes development of severe pulmonary hypertension
Analysis of registry data leads MHH researchers to new insights into certain forms of the disease About one percent of the world's adult population suffers from pulmonary hypertension (PH). There are many forms of this disease. One of them is idiopathic pulmonary arterial hypertension (IPAH). This is a rare but very severe form of pulmonary hypertension.

New app helps Syrian refugees deal with post-traumatic stress
Researchers at Leipzig University have partnered with Syrian refugees and an agency for e-mental health services to develop and scientifically test an app to help users deal with post-traumatic stress and related mental strain. The app - Sanadak - has now been published in Arabic and German and can be downloaded free of charge.

Signaling pathway in the brain to control food intake decoded
Signaling pathway in the brain to control food intake decoded
Binge eating bye bye: Signaling pathway in the brain to control food intake decoded A group of researchers has found a completely new approach to treating eating disorders. The scientists have demonstrated that a group of nerve cells in the hypothalamus (known as AgRP, agouti-related peptide neurons) control the release of endogenous lysophospholipids, which in turn control the excitability of nerve cells in the cerebral cortex, stimulating food intake.

Tracking down the causes of rare diseases in children
Tracking down the causes of rare diseases in children
The causes of intelligence impairment or epilepsy remain unexplained in more than 50 per cent of cases. Together with international colleagues, researchers at Leipzig University Hospital have discovered two genes with mutations that cause neurodevelopmental disorders in children. Their findings have now been published in scientific journals.

Importance of Selenium in the Opening Stages of Protein Synthesis
An international team of researchers with members from Freie Universität Berlin has made an important contribution to our understanding of the essential trace element selenium. The team was able to demonstrate how selenocysteine is incorporated into the proteins of eukaryotes. Using a specialized cryo-electron microscope, the researchers from Charité - Universitätsmedizin Berlin, the Max Planck Institute for Molecular Genetics, Rutgers University, New Jersey, USA, and the University of Illinois, Chicago, USA, succeeded in visualizing the first steps in selenoprotein synthesis.

Protein changes in the liquor indicate inflammatory processes in the brain
Alzheimer's, Parkinson's and other neurodegenerative diseases are associated with inflammatory processes in the brain. German researchers have succeeded in identifying a group of proteins in the liquor that could provide information about such inflammatory processes. As so-called biomarkers, the proteins could help to better understand disease processes in the future and to test the effect of potential drugs against brain inflammation.

Cell Biology: Diversity of centrosomes
Scientists from LMU and Helmholtz Munich have gained new insights into the human centrosome, whose malfunction is linked to many neurodevelopmental disorders. The centrosome is the organelle responsible for the organization of the cytoskeleton during cell division, an essential function in organisms from yeast to humans.

06/15/2022 Similar to the vaccines against the coronavirus, RNA-based antibiotics could significantly improve modern medicine. Research teams from Würzburg have investigated the prerequisites that such antibiotics must meet for this strategy to work. In the fight against the Covid-19 pandemic, mRNA-based vaccines have impressively demonstrated their potential.

Thanks to umbilical cord stem cells: First successful treatment of severe pulmonary hypertension
Hannover Medical School doctors successfully treat three-year-old girl. Clinical researchers at Hannover Medical School (MHH) have succeeded for the first time worldwide in stopping the usually fatal course of the disease in severe pulmonary hypertension thanks to a novel therapeutic approach. A three-year-old girl suffering from so-called pulmonary arterial hypertension (PAH) was treated for six months a total of five times with mesenchymal stem cell products obtained from a human umbilical cord.

3D printed, bioinspired heart valves
Researchers have developed 3D printed artificial heart valves designed to allow a patient's own cells to form new tissue. To form these scaffolds using melt electrowriting - an advanced additive manufacturing technique - the team has created a new fabrication platform that enables them to combine different precise, customized patterns and hence to fine-tune the scaffold's mechanical properties.
