A big question on people’s minds these days: How long does immunity to SARS-CoV-2 last following infection? Now a research team from La Jolla Institute for Immunology (LJI), The University of Liverpool and the University of Southampton has uncovered an interesting clue. Their new study suggests that people with severe COVID-19 cases may be left […]
Researchers find that CD8 T cells remain in the bloodstream, do not enter organs and other tissues
Immune cells called “killer T cells,” also known as cytotoxic or cytolytic CD8 T cells, normally stay in the bloodstream and do not enter organs and other tissues, according to a new study from scientists in the Perelman School of Medicine at the University of Pennsylvania. The discovery, published in Cell, may help resolve many […]
Stable connections between nerve cells are the basis of memory
Memories are part of our lives, the good and the bad. Through our senses, experiences reach our brain where networks of nerve cells encode them into a memory. It was previously unclear why only certain nerve cells join together for this purpose. Researchers from the Max Planck Institute of Psychiatry in Munich have now discovered […]
Release of immature blood cells from bone marrow as a signature of severe COVID-19
In severe cases of COVID-19 disease, not only classic immune cells play a role. In particular, the release of immature precursor cells from the bone marrow into the blood indicates a particularly severe course of the disease and could contribute to complications. This has been shown by an international research team involving the DFG Cluster […]
Stem cells: New insights for future regenerative medicine approaches
Stem cells are considered one of the most promising tools in the field of regenerative medicine because they are a cell type that can give rise to all the cells in our bodies and that has the potential to be used to treat tissue loss due to damage or disease. Stem cells that are similar […]
How to prevent the spread of tumor cells via the lymph vessels
What role do the lymphatic vessels play in the metastasis of cancer cells? Scientists from the German Cancer Research Center and the Mannheim Medical Faculty of the University of Heidelberg developed a method to investigate this question in mice. The aim of the work was to identify new ways to block the dangerous colonization and […]
Study identifies brain cells most affected by epilepsy and new targets for their treatment
Epilepsy is one of the most common neurological diseases. It is caused by a malfunction in brain cells and is usually treated with medicines that control or counteract the seizures. Scientists from the Faculty of Health and Medical Sciences, University of Copenhagen and Rigshospitalet have now identified the exact neurons that are most affected by […]
Circular RNA molecule not found in cancer cells after all
A new research result from Aarhus University shows that a so-called circular RNA molecule, which has been designated as carcinogenic, is actually not found in cancer cells. The results have just been published in Nature Communications. In a major surprise, researchers from Aarhus University have discovered that an otherwise extensively studied carcinogenic RNA molecule is […]
Method to derive blood vessel cells from skin cells suggests ways to slow aging
Salk scientists have used skin cells called fibroblasts from young and old patients to successfully create blood vessels cells that retain their molecular markers of age. The team’s approach, described in the journal eLife on September 8, 2020, revealed clues as to why blood vessels tend to become leaky and hardened with aging, and lets […]
Chemicals in e-cigarettes 'damage cells in lungs and blood vessels'
Chemicals in e-cigarettes mix to form entirely new combinations that are toxic to lung cells and blood vessels, scientists discover Researchers tested the effects of vaping chemicals on human cells in lab tests They found when the chemicals mixed they became unstable and harmful Study adds to growing evidence that e-cigarettes are not safe or […]
