Thalamus Found to Modulate Cortical Sensitivity to Touch

The cerebral cortex processes sensory information via a complex network of neural connections. How are these signals modulated to refine perception? A team from the University of Geneva (UNIGE) has identified a mechanism by which certain thalamic projections target neurons and modify their excitability.

PD-1 Guides T Cells to Become Long-Term Immune Defenders in the Skin

Weill Cornell Medicine researchers have discovered that PD-1—a molecule best known for putting the brakes on immune cells—also plays a critical role in helping T cells become long-term immune defenders in the skin.

Discovery of New Mitophagy Trigger Offers Hope for Parkinson’s Disease

Autophagy is essentially the 'rubbish collection' of our cells. If there are problems in this process, which is so important for our health, diseases such as Parkinson's can result. In their latest study, leading cell biologists at the Max Perutz Labs at the University of Vienna investigated mitophagy – a form of autophagy – and came to a remarkable conclusion: the researchers have described a new trigger for mitophagy.

Uncovering the Molecular Roots of Neural Stem Cell Decline

Age often brings a gradual decline in the ability to learn new things and retain memories. This phenomenon, often associated with the elderly, is linked to the brain's deteriorating capacity to generate new neurons-a process that primarily occurs in the hippocampus -as neural stem cells (NSCs) divide and mature.

How DNA Packaging Shapes p53 Activity

Each cell in our bodies carries about two meters of DNA in its nucleus, packed into a tiny volume of just a few hundred cubic micrometers-about a millionth of a milliliter.

New Computer Program Mimics Human and Animal Cell Behavior

Using mathematical analysis of patterns of human and animal cell behavior, scientists say they have developed a computer program that mimics the behavior of such cells in any part of the body.
