Heterochronic Parabiosis
A preprint published on bioRxiv, whose authors include well-known biogerontologist Vadim Gladyshev, has shown us many interesting details of the effects that heterochronic parabiosis has on aging mice. An old concept studied in new depth Heterochronic parabiosis is the linking of the circulatory systems of young and aged animals. While the researchers note that this...
Bone Marrow
In a study published in Aging, researchers have found that younger hematopoietic cells can restore older hematopoietic cells through microvesicles, which are facilitators of intercellular communication. Why we Age: Altered Intercellular CommunicationAltered intercellular communication, as described in the Hallmarks of Aging, is the change in signals between cells that can lead to some of the...
DNA Blood Cells
Researchers publishing in Cell Stem Cell have identified a protein that helps hematopoietic stem cells (HSCs) both in ex vivo cultures and in aging tissues. The problem with culturing cells Why we Age: Loss of ProteostasisThe loss of proteostasis is the failure of the protein building machinery of the cell and the accumulation of misfolded...
UCSD Blood Flow Monitor
Researchers from the University of California San Diego have developed a new non-invasive way to measure blood flow using an ultrasound patch [1]. Realtime blood flow monitoring just got easier This new flexible polymer patch sticks to the skin and can monitor the flow of blood in vessels up to 14 centimeters deep into the...
X10 Young Blood
On this episode of X10, we talk about a plasma transfusion experiment that studied what happens when young plasma is injected into older animals. Script Is the blood of the young really an elixir of youth? Can it keep us healthy as we age, and, if so, what hidden components give it this great power?...
Blood cells in an artery
A mouse study published in Aging Cell has outlined the similarities between artificially restricted cerebral blood flow and the reduced blood flow associated with aging. Aiming to understand vascular dementia Prior research has shown that reduced cerebral blood flow, known as hypoperfusion, results in vascular dementia and brain atrophy through multiple mechanisms, including neuroinflammation and...
