A new approach to recording cellular activities
Potential for accelerating research: A novel chemical labeling method allows transient events in cells to be recorded for later analysis
27-Feb-2024 - In living cells, a vast number of transient events occur simultaneously, each of them important for a given cell in carrying out its function. The faithful recording of these transient activities is a prerequisite for a molecular understanding of life, yet obtaining such recordings is extremely ...
A new Achilles heel of the bacterial cell wall
How a single regulatory protein acts as a multi-tool of bacterial cell wall remodeling: New hope against bacterial infections
24-Jul-2023 - The bacterial cell wall must be constantly remodeled in order to grow and divide. This involves the close coordination of lytic enzymes (autolysins) and peptidoglycan synthesis. Researchers led by Prof. Dr. Martin Thanbichler have now found that a central regulator can control completely ...
Can we promote healthy ageing of our cells?
The "firefighter" protein calls for the degradation of defective proteins
21-Jun-2023 - All biological processes in our cells are constantly monitored to prevent the accumulation of defective proteins. In the worst case, such "protein clumps" can trigger diseases. The synthesis of new proteins is particularly susceptible to errors. Erronous proteins must then be removed by our ...
Poorly insulated nerve cells promote Alzheimer’s disease in old age
The results of the study show, for the first time, that defective myelin in the aging brain increases the risk of Aꞵ peptide deposition
08-Jun-2023 - Alzheimer’s disease, an irreversible form of dementia, is considered the world’s most common neurodegenerative disease. The prime risk factor for Alzheimer’s is age, although it remains unclear why. It is known that the insulating layer around nerve cells in the brain, named myelin, degenerates ...
Wiggly proteins guard the genome
Dynamic network in the pores of the nuclear envelope blocks dangerous invaders
03-May-2023 - Tiny pores in the cell nucleus play an essential role for healthy aging by protecting and preserving the genetic material. A team in Germany from the Department of Theoretical Biophysics at the Max Planck Institute of Biophysics in Frankfurt am Main and the Synthetic Biophysics of Protein ...
Hungry? Brain tells liver to start recycling
Brain releases hormone after short fasting that boosts autophagy
20-Apr-2023 - Fasting triggers autophagy in our body. The body switches on the waste disposal system in the cells and gains new energy. Researchers at the Max Planck Institute for Metabolism Research in Cologne have now shown in mice that the brain plays a decisive role in this process. Even after a short ...
Creating 3D objects with sound
Scientists introduce a new technology to assemble matter in 3D using sound waves for 3D printing
14-Feb-2023 - Scientists from the Micro, Nano and Molecular Systems Lab at the Max Planck Institute for Medical Research and the Institute for Molecular Systems Engineering and Advanced Materials at Heidelberg University have created a new technology to assemble matter in 3D. Their concept uses multiple ...
Protein droplets may cause many types of genetic disease
Malfunction of cellular condensates is a disease mechanism relevant for congenital malformations, common diseases, and cancer
10-Feb-2023 - Most proteins localize to distinct protein-rich droplets in cells, also known as “cellular condensates”. Such proteins contain sequence features that function as address labels, telling the protein which condensate to move into. When the labels get screwed up, proteins may end up in the wrong ...
Structures considered key to gene expression are surprisingly fleeting
Study finds genome loops don’t last long in cells; theories of how loops control gene expression may need to be revised
20-Apr-2022 - In human chromosomes, DNA is coated by proteins to form an exceedingly long beaded string. This “string” is folded into numerous loops, which are believed to help cells control gene expression and facilitate DNA repair, among other functions. A new study from the Massachusetts Institute of ...
A new dimension in Stem Cell Signaling
Molecular morse code in stem cells encrypting differentiation information revealed
01-Mar-2022 - Divide, differentiate or die? Making decisions at the right time and place is what defines a cell’s behavior and is particularly critical for stem cells of an developing organisms. Decision making relies on how information is processed by networks of signaling proteins. The teams around Christian ...
