Scientists Find an Unusual Weapon Against Virus
Boosting Weak Immune System
19-Oct-2023 - Infections with cytomegalovirus (CMV) are extremely common and often pose no major threat to the vast majority of people. They can however be deadly for people whose immune system is weakened, e.g., after bone marrow transplantation. Current treatments against CMV infections are very limited and ...
Running on fumes? How fruit flies protect their brains during periods of starvation
Fruit flies stay sharp by flipping a metabolic switch in the brain
29-Jun-2023 - A new study led by scientists from TUD Dresden University of Technology reveals that the cells in the fruit fly brain possess a remarkable ability to shift their energy production to fats and send signals to the body's other organs, prompting them to start delivering lipids from fat stores to the ...
Benefits of “Zombie” Cells
Lessons From the Salamanders: Senescent Cells Aid Regeneration
17-Apr-2023 - Scientists show that so called senescent cells, i.e., cells that have permanently stopped dividing, boost production of new muscle cells to enhance regeneration of lost limbs in salamanders. Senescent cells, often referred to as "zombie" cells, have long been associated with aging and disease. ...
A glimpse of a cell’s sense of touch
Sensing the tissue architecture and cells change fate
03-Jan-2023 - Building tissues and organs is one of the most complex and essential tasks that cells must accomplish during embryogenesis. In this collective task, cells communicate through a variety of communication methods, including biochemical signals - similar to a cell's sense of smell - and mechanical ...
How Colon Cancer Hides from the Immune System
Researchers Identify New Targets for Immunotherapy in Colon Cancer
04-Apr-2022 - Scientists identify a pathway of immune cell inhibition that may provide the basis for novel approaches to immunotherapy of colon cancer. Their results also highlight important roles of the intestinal microbiota in the development of the disease. Colon cancer is one of the most common types of ...
Immune Cells Forget (Cell) Culture Shock
The results pave the way to new macrophage-based cell therapies
28-Feb-2022 - A recent study shows that certain immune cells can restore their normal functions when introduced back into the body, even after being multiplied in the laboratory to large numbers – the results pave the way to new cell therapies. Macrophages are immune cells crucial for immune response, tissue ...
Hydraulic instability decides who’s to die and who’s to live
Researchers discover that a mechanical cue is at the origin of cell death decision
01-Jun-2021 - In many species including humans, the cells responsible for reproduction, the germ cells, are often highly interconnected and share their cytoplasm. In the hermaphrodite nematode Caenorhabditis elegans, up to 500 germ cells are connected to each other in the gonad, the tissue that produces eggs ...
How do our cells respond to stress?
Molecular biologists reverse-engineer a complex cellular structure that is associated with neurodegenerative diseases such as ALS
23-Apr-2020 - Cells are often exposed to stressful conditions that can be life threatening, such as high temperatures or toxins. Fortunately, our cells are masters of stress management with a powerful response program: they cease to grow, produce stress-protective factors, and form large structures, which are ...
