Help for the weakened heart
Help for the weakened heart
MHH research team demonstrates how inflammatory cells improve the function of diseased heart muscle cells Heart failure or cardiac insufficiency is one of the most common causes of death in Germany and is caused by heart attacks, high blood pressure or heart valve defects. The heart is then no longer able to pump a sufficient amount of blood through the body and supply organs, muscles or other tissues with enough oxygen and nutrients.

New test improves diagnosis of rare liver disease
New test improves diagnosis of rare liver disease
Polyreactive antibodies as markers for autoimmune hepatitis Autoimmune hepatitis (AIH) is a chronic liver inflammation that is triggered by an immunological malfunction. In this case, the immune system falsely recognises the patient's own liver cells as "foreign to the body". The symptoms of this rare liver disease are unspecific, and the exact cause is not yet known.

Tackling the collateral damage from antibiotics
Tackling the collateral damage from antibiotics
Antibiotics help us to treat bacterial infections and save millions of lives each year. But they can also harm the helpful microbes residing in our gut, weakening one of our body's first lines of defence against pathogens and compromising the multiple beneficial effects our microbiota has for our health.

How a small RNA and a small protein regulate the metabolism of cholera bacteria and the production of the cholera toxin The human gut is a multi-species habitat that can control our health and well-being. Bacteria, viruses and microbial fungi are part of this complex microbial community and help us with our digestion and immune defense.

Protein causes more severe cancer disease in men A remarkable number of life-threatening diseases manifest more severely in males than in females. One current example is COVID-19 caused by SARS CoV-2. Another example is the significantly higher risk of severe cancer progression for men. A research team at the Technical University of Munich (TUM) has now discovered a molecular cause for this difference between sexes.

B cells of the immune system discovered in the meninges
B cells of the immune system discovered in the meninges
A comprehensive analysis of white blood cells in the tissue surrounding the brain / Study published in the journal "Nature Neuroscience" The brain holds numerous unsolved medical mysteries. Only a few years ago it was discovered that the outer layer of the meninges is interlaced with lymphatic vessels.

Molecular Achilles heel of cancer cells discovered
Molecular Achilles heel of cancer cells discovered
Changes in fat metabolism of colorectal cancer cells demonstrated for the first time Where does a malignant tumor obtain the energy to keep growing? That is a key question in cancer research. If the energy source were known, the tumor could be "starved". Researchers have now laid the foundation for this approach: For the first time, they have demonstrated a fundamental difference in the fat metabolism of healthy cells in the inner lining of the intestinal tract and colorectal cancer cells.

Insights into the cellular and molecular changes in male infertility
Insights into the cellular and molecular changes in male infertility
"You can't see the wood for the trees" is a phrase which we certainly don't associate immediately with the medical examination and analysis of testicles. But in a certain way it applies here, too: testicles consist of many different types of cells, and up to now this complex quality prevented these types from being isolated and then analysed.

Messengers from gut to brain
Messengers from gut to brain
Seen for the first time: T cells traveling from the gut and skin to the central nervous system Scientists have long been aware of a link between the gut microbiome and the central nervous system (CNS). Until now, however, the immune cells that move from the gut into the CNS and thus the brain had not been identified.

Bypassing side effects: Nanocontainers transport active ingredients directly to their target
Bypassing side effects: Nanocontainers transport active ingredients directly to their target
Using nanoparticles, a Jena research team implemented the targeted transport of an active ingredient into liver tissue. Using nanoparticles, a Jena research team implemented the targeted transport of an active ingredient into liver tissue. The particles were functionalized with a dye that is specifically absorbed by liver cells, and they carried an inhibitor of the signal protein PI3Kinase ? , which contributes to the development of liver failure in sepsis.

Hobit Turns Immune Cells Into Killers
Hobit Turns Immune Cells Into Killers
08/30/2021 Against infections, tumours and inflammations, immune cells are locally positioned as rapid reaction forces in the organs of the body. On site, they specialise and take on various tasks. When pathogens invade the human body, a rapid response is required. At the forefront of the immune response are special immune cells.

New approach identifies T cells in Covid-19 patients
Immune cell profile reveals appearance, number and activity level against SARS-CoV-2 T cells play a decisive role in fighting the coronavirus and preventing infected individuals from becoming seriously ill. They identify and fight the virus directly within the infected cells. A team of researchers working in Munich have produced a precise profile of the T cells that respond to SARS-CoV-2 and described them at various stages of the illness.

Understanding Lung Damage in Patients with Covid-19
Model to serve as basis for new therapeutic strategies / Joint press release by Charité - Universitätsmedizin Berlin, the MDC, and Freie Universität Berlin Covid-19 disease severity is determined by the individual patient's immune response. The precise mechanisms taking place inside the lungs and blood during the early phase of the disease, however, remain unclear.

Taking aim at skin bacteria
Enzyme treatment of skin samples improves microbiome analysis Healthy skin has a bacterial shield to protect against germs: the microbiome. This complex assembly of microorganisms was previously believed to be difficult to decipher. A team of researchers has now succeeded in using the enzyme benzonase to identify the living bacteria in skin swabs through sequencing.

Intranasal Droplets and Sprays Could Help Tackle SARS-CoV-2
Researchers from Freie Universität Berlin and the University of Bern have published the results of a groundbreaking study No 155/2021 from Aug 10, 2021 Scientists at Freie Universität Berlin and the University of Bern (Switzerland) have developed highly effective SARS-CoV-2 preclinical vaccine candidates that can be administered in the form of nasal drops or sprays.

Study tracks global death toll of COVID-19 pandemic
Comparing the impact of COVID-19 between countries or during a given period of time is challenging because reported numbers of cases and deaths can be affected by testing capacity and reporting policy. The current study provides a more accurate picture of the effects of COVID-19 than using these numbers, and may improve our understanding of this and future pandemics.

Combination vaccines against Covid-19 tested
Immune response stronger than after two doses of AstraZeneca vaccine People under the age of 60 who initially received a vaccine from AstraZeneca should be given an mRNA vaccine at their second appointment. This is recommended by the German Standing Committee on Vaccination. However, up until now, there were no data available to indicate to what extent the human organism would react to such a combined vaccination and start to form antibodies.

New strategy against sepsis
New strategy against sepsis
Some cases of bloodstream infections are mild, but many have a fatal outcome - the reasons for these differences have remained in the dark despite decades of research. Researchers from the Cluster of Excellence "Controlling Microbes to Fight Infections" (CMFI), the Interfaculty Institute of Microbiology and Infection Medicine Tübingen (IMIT) at the University of Tübingen and the German Center for Infection Research (DZIF) have now discovered a possible cause and on this basis developed a new experimental strategy to combat bacterial sepsis.

Energy for undisturbed rest
Energy for undisturbed rest
07/29/2021 In the fruit fly Drosophila, a hormone helps to balance rest and activity. This is shown by a new study of a research team led by the University of Würzburg. Might humans have a hormone with comparable function? Searching for food, eating, resting: in rough terms, this is the rhythm of life that many animals follow.
