Researchers identify novel protein that reduces adverse effect of hypertonicity

A University of Houston College of Medicine researcher has found how a protein inside the body reduces the adverse effects of hypertonicity, an imbalance of water and solutes inside cells. Hypertonicity causes cell shrinkage and eventual cell death.

Study: "Memory" T cells that recognize common cold coronaviruses also recognize SARS-CoV-2

Your immune system's "memory" T cells keep track of the viruses they have seen before. This immune cell memory gives the cells a headstart in recognizing and fighting off repeat invaders.

Biomedical engineers create artificial organelles to control biological function in cells

Biomedical engineers at Duke University have demonstrated a method for controlling the phase separation of an emerging class of proteins to create artificial membrane-less organelles within human cells.

UC Riverside joins ATP-Bio to preserve a wide range of biological systems

The National Science Foundation, or NSF, announced today that it has awarded a $26 million Engineering Research Center grant to the University of Minnesota and Massachusetts General Hospital, in collaboration with UC Riverside and UC Berkeley.

Decoy receptor neutralizes SARS-CoV-2 virus in tissue cultures

As the COVID-19 pandemic continues to spread, scientists and health care providers are seeking ways to keep the coronavirus from infecting tissues once they're exposed. A new study suggests luring the virus with a decoy - an engineered, free-floating receptor protein - binds the virus and blocks infection.

New method reveals the dynamics of cell development and gene activity

Traditional single-cell sequencing methods help to reveal insights about cellular differences and functions - but they do this with static snapshots only rather than time-lapse films.

Chlamydiae need a lot of glutamine to multiply in human cells

If chlamydiae want to multiply in a human cell, the first thing they need is a lot of glutamine. Würzburg researchers have clarified how the pathogenic bacteria obtain this substance.

Membrane protein regulates epigenetic plasticity by mediating iron endocytosis

CNRS researchers at the Institut Curie have recently shown that cancer cells use a membrane protein that has been known for several decades to internalise iron.

High-speed atomic force microscopy reveals diverse amyloid structures and dynamics

In the human body, proteins sometimes occur in fibrillar aggregates called amyloids. Although certain amyloids are known to have a biological function, amyloid formation is often associated with pathologies, including Alzheimer's and Parkinson's diseases.

New method to detect rare circulating tumor cells in blood samples

Metastasis - the development of tumor growth at a secondary site - is responsible for the majority of cancer-related deaths. It occurs when the primary tumor site sheds cancerous cells which are then circulated through the body via blood vessels or lymph nodes.

Study: ANGEL2 enzyme performs unique chemical reaction at the end of RNA molecules

Scientists led by Javier Martinez from the Max Perutz Labs, a joint venture of the Medical University of Vienna and the University of Vienna, have identified a unique chemical reaction at the end of RNA molecules for the first time in human cells.

Multiple, intertwined cell death systems to prevent the spread of 'intracellular' bacteria

Melbourne researchers have revealed the multiple, intertwined cell death systems that prevent the spread of the 'intracellular' bacterium Salmonella, an important cause of typhoid fever which kills more than 100,000 people annually.

Immunosuppressive steroids help tumors to evade the immune system

A new study has revealed that tumors can evade the immune system by telling immune cells to produce immunosuppressive steroids.

Mice born with Fragile X syndrome have fewer cell antennas

Structures called primary cilia - which act like TV antennas for cells to detect signals - are present in fewer numbers in mice born with Fragile X syndrome, according to researchers from The University of Texas Health Science Center at San Antonio.

Study finds fungal isolates with high levels of virulence in different hospitals

A group of researchers from Brazil, Denmark, Italy and Spain analyzed 884 samples of fungi of the genus Candida collected from 16 hospitals and found a significant number of clusters in more than one hospital.

New maps of chemical marks on DNA could help illuminate the causes of developmental disorders

In research that aims to illuminate the causes of human developmental disorders, Salk scientists have generated 168 new maps of chemical marks on strands of DNA--called methylation--in developing mice.

Study reveals mechanisms of mechanical stretch induced skin expansion

The capacity of the skin to expand by mechanical stretching has been used for decades in plastic and reconstructive surgery to generate an excess of skin that can be used to repair birth defects, damaged tissues, and breast reconstruction after mastectomy.

Research may provide new insights into wound healing

When we get a wound on our skin, the cells in our bodies quickly mobilize to repair it. While it has been known how cells heal wounds and how scars form, a team led by researchers from Washington University in St. Louis has determined for the first time how the process begins, which may provide new insight into wound healing, fibrosis and cancer metastasis.
