Diluting blood plasma rejuvenates tissue, reverses aging in mice
New study suggests that plasma exchange could be the key to unlocking the body’s regenerative capacities UNIVERSITY OF CALIFORNIA – BERKELEY CREDIT: IMAGE COURTESY IRINA CONBOY Berkeley — In 2005, University of California, Berkeley, researchers made the surprising discovery that making conjoined twins out of young and old mice — such that they share blood...

New structural ‘map’ solves mysteries of gigantic gene regulator
WALTER AND ELIZA HALL INSTITUTE Structural biology has been used to ‘map’ part of a protein called SMCHD1, explaining how some changes in SMCHD1 cause certain developmental and degenerative conditions. Publishing in the journal Science Signaling, the Walter and Eliza Hall Institute team revealed the structure of the portion of the SMCHD1 protein that is...

Blocking sugar metabolism slows lung tumor growth
by Emily Packer, Ecole Polytechnique Federale de Lausanne Blocking a pair of sugar-transporting proteins may be a useful treatment approach for lung cancer, suggests a new study in mice and human cells published today in eLife. Cancer cells use a lot of sugar to fuel their rapid growth and spread. This has led scientists to...

Study yields clues to how drug may boost aged mitochondria
An experimental drug that has been shown to improve the function of diseased and aged mitochondria binds to 12 key proteins involved in energy production, researchers at the University of Washington School of Medicine have found. The drug, elamipretide, also called SS-31, has shown promise for treating rare inherited diseases that affect the mitochondria, the...

How targeting killer T cells in the lungs could lead to immunity against respiratory viruses
by Salk Institute A significant site of damage during COVID-19 infection is the lungs. Understanding how the lungs’ immune cells are responding to viral infections could help scientists develop a vaccine. Now, a team of researchers led by Salk Professor Susan Kaech has discovered that the cellsresponsible for long-term immunity in the lungs can be...

Overactive enzyme causes hereditary hypertension
by Max Delbrück Center for Molecular Medicine A Turkish family from a village near the Black Sea caught the attention of medical researchers in the early 1970s, when a physician discovered that many members of this large family had both unusually short fingers and astronomically high blood pressure, sometimes twice as high as that of...

No use hiding your age: Scientists develop an eye scanner that can detect and track biological ageing in humans for the first time by analysing proteins in their lenses
he team created an eye scanner that can tell someone’s ‘real’ or biological age There is no universal method for tracking a person’s biological age, authors say By building this new scanner they were able to create one method to see the age The team say that biological age is a more accurate health measure...

Birmingham scientists ‘re-train’ immune system to prevent attack of healthy cells
The body’s immune system can be re-wired to prevent it from recognising its own proteins which, when attacked by the body, can cause autoimmune diseases like multiple sclerosis, a significant new study by UK scientists has found. Autoimmune diseases are caused when the immune system loses its normal focus on fighting infections or disease within...

Heralding a new era in protein analytics
Systems biologist Paola Picotti receives this year’s Rössler Prize for her groundbreaking work in the field of proteomics. She has developed a method of measuring structural changes in thousands of proteins at the same time, paving the way for personalised therapy. The announcement in March 2003 that a human genome had been completely sequenced for...
