Blame Tau for Much of the Harm Caused by Cerebral Amyloid Angiopathy
Cerebral amyloid angiopathy, as the name might suggest, is an amyloidosis. It involves the build up of amyloid-β, and in some cases significant amounts of other forms of amyloid, in blood vessel walls in the brain, and dysfunction results. As the brain is a nutrient-hungry organ, any disruption of the blood supply will cause issues over the long term, contributing to the development of dementia. As most readers here no doubt know, amyloid-β deposits are the primary feature of early Alzheimer's disease, at the stages leading into mild cognitive impairment. Amyloid deposition and the changes in cellular biochemistry that r...

RAGE Knockout Reduces Age-Related Kidney Damage in Mice
RAGE is the receptor for advanced glycation end-products (AGEs), the mechanism by which cells react to the presence of AGEs. AGEs are metabolic byproducts that are both created in the body and present in the diet; cooking animal fat produces AGEs, for example. Diets heavy in meat and the related, fun, unhealthy products so prevalent in this modern calorie-packed world of ours are also heavy in AGEs of various sorts. It remains a topic for discussion as to the degree to which dietary AGEs are a problem, however. Do they contribute significantly to the issues caused by AGEs in general, or only in conditions in which metaboli...

In this report, we propose that the molecular mechanisms of beneficial actions of CR should be classified and discussed according to whether they operate under rich or insufficient energy resource conditions. Future studies of the molecular mechanisms of the beneficial actions of CR should also consider the extent to which the signals/factors involved contribute to the anti-oxidative, anti-inflammatory, anti-tumor and other CR actions in each tissue or organ, and thereby lead to anti-aging and prolongevity.

Anti-Amyloid CPHPC Therapy Used in a Clinical Trial for Alzheimer's Disease
CPHPC, now called miridesap, is a cautionary tale of what all too often happens to promising approaches in the field of medical development, once they advance to the point of expensive clinical trials and the requirement for partners with deep pockets to fund those trials. Miridesap was one of the earlier methodologies demonstrated to clear out transthyretin amyloid from tissues. This form of amyloid appears to be an important contribution to risk of cardiovascular disease, as well as a factor in osteoarthritis, and the evidence suggests it is the majority cause of death in supercentenarians. Its accumulation in old tissue...

First Generation Pharmaceutical Treatments for Transthyretin Amyloidosis Continue to Make Progress
Perhaps a score of the countless proteins in the human body misfold in large amounts in later life. The misfolded form is insoluble, leading to solid deposits of the protein in and around cells. These problem proteins are known as amyloids, and the accumulation of amyloids is one of the root causes of aging. Amyloidosis conditions arise from the presence of amyloid and the disruptive effect it has on cellular biochemistry. The best known form of amyloid is the amyloid-β thought to cause Alzheimer's disease, but the research community is beginning to appreciate that other forms may be just as big a problem over the course ...

Evidence for Herpesvirus Infection to be a Significant Cause of Alzheimer's Disease
A few recent papers have, collectively, added evidence for persistent viral infection to be a significant contributing cause of Alzheimer's disease. A number of viruses in the herpesvirus family are prevalent in the population but cause few obvious symptoms, such as HSV-1 and cytomegalovirus (CMV). Some of these, particularly CMV, are already under suspicion as being the cause of long-term dysfunction in the immune system. Viral infection is an attractive way to explain why only some of the people who exhibit all of the known risk factors for Alzheimer's disease actually go on to develop the full clinical manifestation of ...

When I am Eighty-Five
I will be 85 somewhere in the mid 2050s. It seems like a mirage, an impossible thing, but the future eventually arrives regardless of whatever you or I might think about it. We all have a vision of what it is to be 85 today, informed by our interactions with elder family members, if nothing else. People at that age are greatly impacted by aging. They falter, their minds are often slowed. They are physically weak, in need of aid. Perhaps that is why we find it hard to put ourselves into that position; it isn't a pleasant topic to think about. Four decades out into the future may as well be a science fiction novel, a far awa...

This study demonstrates that small peptide domains derived from native protein amelogenin can be utilized to construct a mineral layer on damaged human enamel in vitro. Six groups were prepared to carry out remineralization on artificially created lesions on enamel: (1) no treatment, (2) Ca2+ and PO43- only, (3) 1100 ppm fluoride (F), (4) 20 000 ppm F, (5) 1100 ppm F and peptide, and (6) peptide alone. While the 1100 ppm F sample (indicative of common F content of toothpaste for homecare) did not deliver F to the thinly deposited mineral layer, high F test sample (indicative of clinical varnish treatment) formed mainly C...

Vast Funding is Available for the Later Stages of Development of any Credible Therapy that Addresses a Cause of Aging
Today I'll point out a couple of recent news items that illustrate there is no funding drought for any group that manages to bring a credible approach to addressing one of the causes of aging to the point of human clinical trials. This is the case even when it is generally understood by all involved that the therapies in question are first generation attempts at implementation, subject to all the normal challenges that brings, and in principle not as good as competing forms of technology that are still at an earlier stage in the process of development. The drought lies in the number of groups who can make it to this stage,...

A Short Report from the Undoing Aging Conference
The LongLongLife team here reports briefly on their time at the recent Undoing Aging conference. This was the first in a series of conferences, hosted jointly by the SENS Research Foundation and Forever Healthy Foundation, that will mix the scientific and academic focus of the SENS rejuvenation research conferences with the biotechnology industry focus of the Rejuvenation Biotechnology conferences. By all accounts the initial Undoing Aging event was well received.
The very first Undoing Aging Congress was held in March 2018 in Berlin, and was attended by 350 people from a total of 36 countries. Initiated by Aubrey...

Tau and α-synuclein act in Synergy to Produce Neurodegeneration
The three most harmful forms of metabolic waste in the aging brain are amyloid-β, hyperphosphorylated tau, and α-synuclein, all of which precipitate into solid deposits with a complex halo of surrounding biochemistry that damages and ultimately kills cells. They contribute to various age-related neurodegenerative conditions that are classified as amyloidosis, tauopathy, and synucleinopathy, respectively. Looking at just one of these forms of waste in isolation misses the real story, however. An aging brain has some of each, and it is apparent from the study of Alzheimer's disease that amyloid-β and tau interact to produ...
