Fight Aging!

What are the important steps in the progression of neurodegenerative diseases characterized by the presence of protein aggregates? These aggregates are misfolded or otherwise altered proteins that precipitate to form solid deposits. This means α-synuclein in the case of Parkinson’s disease, or amyloid-β and tau in the cause of Alzheimer’s disease, to pick the best…

Fight Aging!

It is quite easy to find correlations between the many varied aspects of aging. People age at different rates, largely due to differences in lifestyle choices: exercise, calorie intake, smoking, and so forth. Genetics are less of an influence. While there is tremendous interest in the genetics of aging, I have to think that this…

Towards Restoration of Neural Stem Cell Function in the Old

Every tissue in the body supported by its own specialized small stem cell populations. The vast majority of cells in the body, known as somatic cells, are limited in the number of times they can divide. Their telomeres shorten with each cell division, and they become senescent or self-destruct when reaching the Hayflick limit on…

Anethole Trithione is a Mitochondrial ROS Blocker

Mitochondria, the power plants of the cell, generate reactive oxygen species (ROS) as a side effect of the energetic operations needed to package fuel supplies used by cellular processes. While ROS are necessary signals in many physiological circumstances, such as the beneficial reaction to exercise, excessive ROS generation can be harmful. Excessive ROS generation is…

The Goal of Fixing the Power Plants of the Cell

The power plants of the cell are, of course, the mitochondria. Every cell has a herd of hundreds of mitochondria roaming its cytoplasm, working to generate ever more copies of the chemical energy store molecule adenosine triphosphate that is used power cellular processes. Mitochondria are the distant descendants of ancient symbiotic bacteria. Like bacteria they…

Targeted Destruction of B Cells Rejuvenates the Immune System, but Other Obstacles Still Block Improvement of Immune Function

B cells are an important part of the adaptive immune system, using antibodies to coordinate the T cell response to pathogens and other targets of opportunity that immune cells should attack. As is the case for all aspects of the immune system, B cell function degenerates with age. Growing numbers of what are known as…

Bioprinting Engineered Tissues Containing Intricate Small-Scale Vascular Networks

The generation of appropriately dense and small-scale capillary networks remains the major roadblock in the progression of tissue engineering, and this has been the case for many years now. Researchers have established the recipes needed to generate functional tissue structures for many organs, from lungs to liver, but in order to grow more than millimeter-thick…

Fight Aging!

Progerin is the malformed version of LMNA, a protein vital to the structure of the cell nucleus. It is the cause of progeria, a rare condition that has the superficial appearance of greatly accelerated aging. It isn’t aging, however, but rather an enormous burden of cellular damage and dysfunction resulting from structural issues in the…

Presenting the SASP Atlas for the Senescence-Associated Secretory Phenotype

The presence of growing numbers of lingering senescent cells is one of the root causes of aging. Vast numbers of cells become senescent every day, but near all are quickly removed, either via programmed cell death or the actions of the immune system. A tiny number survive, however, and that alone would eventually be enough…

Fight Aging!

Advanced glycation end-products (AGEs) form in tissues as a side-effect of the normal operation of cellular metabolism where it touches on the processing of sugars. There are many types of AGEs, most short-lived, but some persistent and challenging for our biochemistry to break down. These persistent AGEs lead to cross-links, binding together molecules in the…
