CellAge Campaign Q&A: Is It Safe To Remove Senescent Cells? | Lifespan.io

Posted by in categories: biotech/medical, health, life extension

Is it safe to remove senescent cells? This is a common question we hear when talking about senolytic therapies designed to remove these problem cells that accumulate with age and play havoc with the body and its ability to repair.


Mantas from CellAge answers a question from one of our readers about senescent cell removal therapy. The removal of senescent cells has become a very hot topic this year with numerous experiments showing positive results for health and disease mitigation.

Classifying Aging As a Disease: The Role of Microbes

Posted by in categories: biotech/medical, health, life extension

The body is under constant invasion by microbes so rejuvenation of the immune system and reduction of imflammation is a big priority for rejuvenation biotechnology.


Recent publications have proposed that aging should be classified as a disease (Bulterijs et al., 2015; Zhavoronkov and Bhullar, 2015; Zhavoronkov and Moskalev, 2016). The goal of this manuscript is not to dispute these claims, but rather to suggest that when classifying aging as a disease, it is important to include the contribution of microbes.

As recently as ~115 years ago, more than half of all deaths were caused by infectious diseases, including pneumonia, influenza, tuberculosis, gastrointestinal infections, and diphtheria (Jones et al., 2012). Since then, the establishment of public health departments that focused on improved sanitation and hygiene, and the introduction of antibiotics and vaccines allowed for a dramatic decrease in infectious disease-related mortality (Report, 1999). In 2010, the death rate for infectious diseases was reduced to 3% (Jones et al., 2012). Simultaneously, as infectious disease-related mortality rates have decreased, global lifespan has increased from ~30 to ~70 years (Riley, 2005).

Bionic pancreas system manages blood sugar levels in patients with type 1 diabetes living at home

Posted by in categories: biotech/medical, cyborgs, engineering, health, transhumanism

The bionic pancreas system developed by Boston University (BU) investigators proved better than either conventional or sensor-augmented insulin pump therapy at managing blood sugar levels in patients with type 1 diabetes living at home, with no restrictions, over 11 days. The report of a clinical trial led by a Massachusetts General Hospital (MGH) physician is receiving advance online publication in The Lancet.

“For study participants living at home without limitations on their activity and diet, the bionic pancreas successfully reduced average blood glucose, while at the same time decreasing the risk of hypoglycemia,” says Steven Russell, MD, PhD, of the MGH Diabetes Unit. “This system requires no information other than the patient’s body weight to start, so it will require much less time and effort by health care providers to initiate treatment. And since no carbohydrate counting is required, it significantly reduces the burden on patients associated with diabetes management.”

Developed by Edward Damiano, PhD, and Firas El-Khatib, PhD, of the BU Department of Biomedical Engineering, the bionic pancreas controls patients’ blood sugar with both insulin and glucagon, a hormone that increases glucose levels. After a 2010 clinical trial confirmed that the original version of the device could maintain near-normal blood sugar levels for more than 24 hours in adult patients, two follow-up trials — reported in a 2014 New England Journal of Medicine paper — showed that an updated version of the system successfully controlled blood sugar levels in adults and adolescents for five days. Another follow-up trial published in The Lancet Diabetes and Endocrinology in 2016 showed it could do the same for children as young as 6 years of age.

Piperlongumine as a Senolytic Drug Candidate with Fewer Side-Effects

Posted by in categories: biotech/medical, health, life extension

Senescent cell removal is the first true rejuvenation therapy to treat one of the aging processes and with human clinicial trials in the next 18 months these are some very exciting times. Here is yet another study showing natural compounds can be used in combination with drugs to kill senescent cells.


Today’s open access research paper outlines the discovery of yet another new candidate drug for the selective destruction of senescent cells. This is an increasingly popular research topic nowadays. Senescent cells perform a variety of functions, but on the whole they are bad news. Cells become senescent in response to stresses or reaching the Hayflick limit to replication. They cease further division and start to generate a potent mix of signals, the senescence-associated secretory phenotype or SASP, that can provoke inflammation, disarray the surrounding extracellular matrix structures, and change behavior of nearby cells for the worse. Then they destroy themselves, or are destroyed by the immune system — for the most part at least. This is helpful in wound healing, and in small doses helps to reduce cancer incidence by removing those cells most at risk of becoming cancerous. Unfortunately a growing number of these cells linger without being destroyed, more with every passing year, and their presence eventually causes significant dysfunction. That in turn produces age-related disease, frailty, and eventually death. Senescent cells are not the only root cause of aging, but they provide a significant contribution to the downward spiral of health and wellbeing, and even only their own would eventually produce death by aging.

The beneficial aspects of senescent cells seem to require only a transient presence, so the most direct approach to the problem presented by these cells is to destroy them every so often. Build a targeted therapy capable of sweeping senenscent cells from tissues, and make it efficient enough to keep the count of such cells low. That is the way to prevent senescent cells form contributing to age-related disease. Working in mice, researchers have produced results such as functional rejuvenation in aged lungs and extended life span through the targeted destruction of senescent cells. Since perhaps only a few percent of the cells in old tissue are senescent, this targeted destruction can be accomplished with few side-effects beyond those generated by off-target effects of the medication itself.

The disturbingly accurate brain science that identifies potential criminals while they’re still toddlers

Posted by in categories: bioengineering, health, neuroscience, science

Scientists are able to use brain tests on three-year-olds to determine which children are more likely to grow up to become criminals. It sounds like Minority Report come to life: An uncomfortable idea presenting myriad ethical concerns. But, though unnerving, the research is nuanced and could potentially be put to good use.

In the study, published in Nature Human Behavior this week, researchers led by neuroscientists at Duke University showed that those with the lowest 20% brain health results aged three went on to commit more than 80% of crimes as adults. The research used data from a New Zealand longitudinal study of more than 1,000 people from birth in the early 1970s until they reached 38 years old. This distribution, of 20% of a population accounting for 80% of an effect, is strong but not unusual. In fact, it follows the “Pareto principle.” The authors write in their paper:

In Pareto’s day, the problem definition was that 20% of families owned 80% of land in Italy. The so-called Pareto principle is alive and useful today: for example, in software engineering, 20% of the code is said to contain 80% of the errors.

Cellular reprogramming reverses signs of aging

Posted by in categories: biotech/medical, health, life extension

An interesting but predictably hyped research study currently doing the rounds. Epigentic changes are one of the Hallmarks of Aging and this study reinforces their importance despite the usual media hype.


Graying hair, crow’s feet, an injury that’s taking longer to heal than when we were 20—faced with the unmistakable signs of aging, most of us have had a least one fantasy of turning back time. Now, scientists at the Salk Institute have found that intermittent expression of genes normally associated with an embryonic state can reverse the hallmarks of old age.

This approach, which not only prompted in a dish to look and behave young again, also resulted in the rejuvenation of with a , countering signs of aging and increasing the animals’ lifespan by 30 percent. The early-stage work provides insight both into the cellular drivers of aging and possible therapeutic approaches for improving human health and longevity.

Aging May Be Reversible: Researchers Rejuvenate Older Mice

Posted by in categories: biotech/medical, health, life extension

Getting old may not be inevitable — scientists have found a way to turn back the clock on human and animal cells, making them look and behave like younger versions of themselves.

The researchers also used the method to treat mice with a rare disease that causes them to age prematurely and die early, and found that the method increased the animals’ lifespan by 30 percent. And, when normal mice received the treatment, they appeared to be rejuvenated, with some of their cells healing faster than normal in response to injury.

The researchers said that their findings may help scientists better understand the process of aging. One day, it may be possible to use a similar approach to ward off age-related diseases in humans, and thus improve people’s health and increase their lifespan, they said.
