A key player in hepatitis A virus infection discovered

How hepatitis A virus manages to enter liver cells called hepatocytes and initiate infection had remained a mystery for fifty years until now.

Collagen maturation regulates PEDF availability, study shows

Cells are like tiny self-contained machines that are constantly fine-tuned in response to both internal and external signals. Some of these signals are induced by extracellular ligands, specialized proteins that bind to specific receptors on the cell surface, stimulating signaling pathways and altering gene expression.

UZH researchers develop new X-ray contrast agent for high-resolution vascular imaging

Various diseases in humans and animals - such as tumors, strokes or chronic kidney disease - damage the blood vessels. Capillaries, the smallest blood vessels in the body, are particularly affected.

Minuscule tracking devices give unprecedented peek into how cells change with time

For the first time, scientists have introduced minuscule tracking devices directly into the interior of mammalian cells, giving an unprecedented peek into the processes that govern the beginning of development.

The eye initiates an immune response in the lens after injury

The lens of the eye is an unusual organ. Unlike most of the body's organs, blood vessels don't reach the lens. If they did, they'd obscure our vision and we wouldn't be able to see.

Biophysicists determine the optimal age of reprogrammed stem cells

Biophysicists from the Moscow Institute of Physics and Technology and Vladimirsky Moscow Regional Clinical Research Institute have determined the optimal age of reprogrammed stem cells suitable for restoring heart tissue.

'Good' bacteria have a niche in our noses, study suggests

Beneficial strains of bacteria residing in our guts, genital tracts, and skin have been shown to play a role in human health, and now, researchers publishing May 26 in the journal Cell Reports suggest that some of these "good" bacteria also have a niche in our noses.

Warwick researchers discover how cells activate autophagy genes during fasting

As modern life-styles and high calorie diets drive the UK's obesity levels up, researchers from the University of Warwick have found how cells respond to fasting and activate the process called autophagy, which means a healthier lifestyle can be promoted to help people maintain a healthy body weight.

Women with Neandertal gene have increased fertility

One in three women in Europe inherited the receptor for progesterone from Neandertals - a gene variant associated with increased fertility, fewer bleedings during early pregnancy and fewer miscarriages.

New technique for fast, easy optimization of antibodies using chicken cells

Antibodies for potential use as medicines can be made rapidly in chicken cells grown in laboratories. Researchers refer to their technique as the human ADLib system, short for autonomously diversifying libraries.

Rejuvenated fibroblasts could be used in regenerative medicine, stem cell engineering

Fibroblasts are the most common connective tissue cells. They produce the structural framework for animal tissues, synthesize the extracellular matrix and collagen, and play a critical role in wound healing.

Researchers identify genetic mechanisms that produce radioresistance in cancer cells

Cancer stem cells are a cell type that was previously little known. They are resistant to irradiation and prevent the effective treatment of many types of cancer. A research group from Innsbruck has now identified two genetic mechanisms that produce this radioresistance.
