Enlarged heart

The Link Between NAD+ and Heart Failure

A paper published today in Nature Cardiovascular Research has explained a relationship between dilated cardiac myopathy (DCM), epigenetic dysregulation, NAD+, and the epigenetic regulatory molecule Kdm8. A gradual decline of ability DCM occurs when the left ventricle of the heart becomes enlarged and loses its ability

Tendon inflammation

Extracellular Vesicles for Tendon Healing

Researchers publishing in Journal of Nanobiotechnology have found that extracellular vesicles derived from young cells are effective in treating a model of a common tendon disease. Tendinopathy and stem cells Swelling, weakness, tenderness, and tendon pain during activities are the characteristic symptoms of chronic tendinopathy [1],

Viral Exposure Might Increase the Risk of Neurodegeneration

In a paper published in Neuron, researchers have shown an association between exposure to various viruses and an increased risk of several neurodegenerative diseases, including Alzheimer’s and Parkinson’s diseases [1]. Roots of neurodegeneration There are many causes underlying neurodegeneration, such as genetic predisposition, toxin exposure, poor

Old DNA

Retroviruses Contribute to the Spread of Cellular Senescence

Scientists have found that the remnants of the ancient retrovirus family HERVK, which reside in our genome, are transcribed more frequently in aged cells. This is caused by cellular senescence and accelerates it, including in the neighboring cells, when those are infected by retroviral particles [1].

Is Increasing Human Lifespan Unnatural?

Whenever the topic of any possible increased healthy longevity through science is discussed, a common objection to developing the technology is that it is unnatural. This argument usually arises during discussions of therapies that directly address the various processes of aging, and it is important to understand their basis

A Light-Sensitive Drug to Remove Senescent Cells

Photosensitive Drug Clears Senescent Cells

Research published in Nature Aging has shown that a photosensitive senolytic drug can be used to selectively remove senescent cells, slowing functional organ aging in mice. A problem of delivery The researchers name three problems with senolytic drugs: specificity to senescent cells (accuracy), controllability of administration

Ultrasound Machine

Ultrasound Rejuvenates Senescent Cells Through Autophagy

In a preprint paper, the researchers have shown that low-frequency ultrasound treatment decreases senescence and improves the physical performance of aged mice [1]. Mechanical approach Cellular senescence, the inability of aged cells to divide while still being metabolically active, is one of the hallmarks of aging.
