Membrane proteins are a basic component of each individual cell of the human body and play a vital role in the cell’s structure, metabolism and transport. They ensure that many substances, such as hormones and other…
For about one hundred years it has been known that nutrient restriction and moderate stress can significantly prolong life. The researchers led by Prof. Mihaela Zavolan and Prof. Anne Spang, both at the Biozentrum of the…
Cells live and survive by taking up proteins, recycling and reusing or degrading them. The proteins are located on the cell surface and are transported from here into the cell’s interior. About 80 percent of these membrane…
Genetic information is protected in the cell nucleus by a membrane that contains numerous nuclear pores. These pores facilitate the traffic of proteins known as importins that deliver molecular cargoes between the nucleus…
Individual visual stimuli are not processed independently by our brain. Rather neurons exchange incoming information to form a coherent perceptual image from the myriad of visual details impinging on our eyes. How our visual…
Our brain generates new neurons throughout life. A diversity of stimuli promotes stem cells in their niche to form neurons that migrate to their place of action. In an animal model Prof. Fiona Doetsch’s team at the…
Hearing loss eventually affects almost everyone: Loud noises or simple aging gradually cause the auditory sensory cells and their synapses in the inner ear to degenerate and die off. The only treatment option is a hearing…
Most living organisms on our planet-whether plants, animals, or humans -contain mitochondria in their cells. Their main function is to supply energy for nearly all cellular processes. To achieve this, mitochondria use the…
In 1949, the Canadian psychologist Donald O. Hebb described that connections between neurons become stronger when the neurons are active at the same time, and that strengthened connections facilitate signal transmission. The…
You are likely to lose around one third of your muscle mass over your lifetime. An excessive loss of muscle mass and muscle strength is known as sarcopenia. As life expectancy increases, so does the number of people…
