Programming synthetic exosomes to optimize wound healing

Scientists create synthetic exosomes with natural functionalities and present their therapeutic application. Scientists from the Max Planck Institute for Medical Research in Heidelberg and colleagues at the DWI Leibniz Institute for Interactive Materials in Aachen have engineered synthetic exosomes that regulate cellular signaling during wound closure. The synthetic structures are […]

Reviewing the Ability of Calorie Restriction to Slow Aging

Calorie restriction is the most studied means to slow aging, and from this numerous lines of work have emerged, each focused on one small subset of the sweeping changes in metabolism that occur in response to a lowered intake of nutrition. Lack of nutrients puts stress on cells and organisms, […]

The Accelerated Aging Produced by Chronic Kidney Disease

Many lines of evidence point to kidney function as being particularly important to the health of organs throughout the body. To pick one example, one of the better known longevity-associated genes, klotho, appears to act in the kidney, and yet is well known for producing improvements in cognitive function. Here, […]

The Impact of Viral Infection on Microglia and the Aging of the Brain

A growing school of thought sees persistent viral infection as an important contributing factor in age-related neurodegeneration. The widely varying burden of infection that is present in the population could help to explain the puzzling epidemiology of conditions such as Alzheimer's disease, in that only some of the people with […]

Researchers use CERN technology to evaluate risk of COVID-19 transmission

The CERN-developed COVID Airborne Risk Assessment tool (CARA) is helping researchers from the University of Geneva assess the effectiveness of different measures to limit SARS-CoV-2 aerosol transmission in schools. Having good safety measures at schools is very important as children start going back to the classroom. But which measures are […]

A Reduced Memory B Cell Population in Older People Impairs Immune Response

The age-related decline of the immune system is complex. There are many facets to the issues of increased systemic inflammation and reduced immune competence. Here, researchers show that a necessary population of memory B cells is reduced with age, and this impairs the ability of the immune system to respond […]
