In Nature Communications, researchers have described how small extracellular vesicles (sEVs) fused with plasma membrane proteins successfully treated heart arrhythmia in a rat model. Why do people need pacemakers? In a healthy heart, the sinoatrial node (SAN) serves as a natural regulator, commanding the heart to regularly contract. As it becomes dysfunctional and fibrotic with...

Researchers publishing in Aging Cell have discovered that cells derived from the human placenta may be useful in estimating the effects of potential anti-aging treatments. A seemingly odd choice Of all the organs in the body, the placenta may be the least concerning with regards to aging; it only exists for at most 10 months,...

Resesarchers have found that thrombospondin-1 (TSP-1), a compound that is critical in growing brain synapses, is secreted by normal astrocytes but not senescent ones. Senescence is harmful to the brain Cellular SenescenceAs your body ages, more of your cells become senescent. Senescent cells do not divide or support the tissues of which they are part;...

In Aging Cell, four Japanese researchers have recently described the aging of the hematopoietic system, which is responsible for the creation of blood. A system that affects all the others Aging and age-related diseases are often discussed in terms of hallmarks, such as senescence and genomic instability. However, the bodies of complex organisms, such as...

Researchers publishing in Aging Cell have found that Hevin, a protein found in the extracellular matrix that increases with age, leads to heart problems in older male mice. Inflammaging contributes to heart disease Chronic InflammationChronic inflammation refers to a persistent, low-grade buzz of immune activity that settles into the body without the drama of an...

In a paper published in Aging Cell, researchers have described how older cells send long interspersed nuclear element-1 (LINE-1) RNA to other cells in extracellular vesicles (EVs), spurring inflammation. Evil EVs In the literature, EVs are often discussed in a therapeutic context, as they can be used to send beneficial signals. However, EVs are the...
