The CellAge AMA is open for questions, come along and ask about biotechnology, senolytics and so on.

Welcome to the CellAge AMA with Mantas Matjusaitis, PhD student in synthetic biology and founder of CellAge. I am here to talk about our work to improve the targeting of dysfunctional “senescent” cells in the body, and thereby aid in their eventual removal. This is important because removal of these cells has been shown to be a critical component in the effort to improve healthy human lifespan.

In short, CellAge is going to develop synthetic DNA promoters which are specific to senescent cells, as the promoters that are currently used for this purpose, such as the p16 gene promoter, suffer from various issues and limitations (not comprehensively targeting all senescent cells, collateral damage in targeting some cells that are not senescent, etc.). You can find more details in our technology video here, and on our Lifespan.io information page.

In Brief

• Facebook billionaire Mark Zuckerberg recently opened his wallet in order to create BioHub, a $600 million center that will focus on working to create a human cell directory.
• By mapping the trillions of cells in the human body, experts would be able to develop new drugs and vaccines to combat — and potentially end — disease.

Last month, we reported on the Human Cell Atlas, a project that plans to provide a detailed reference map of the human body’s trillions of cells. Yes, trillions. Once completed, the project could revolutionize healthcare by giving doctors and researchers a better way to predict, diagnose, and treat diseases.

Initiatives like this need funding – so Facebook billionaire Mark Zuckerberg opened his wallet and founded BioHub, a $600 million center that will focus on helping create a human cell directory. Zuckerberg and his wife, Priscilla Chan, plan to give away $3 billion over 10 years to fight disease, and BioHub is the couple’s first initiative.

Nice. Personalized Cancer Vaccine showing promise.

A majority of patients in a small clinical trial have been in remission from a deadly type of cancer for more than four years.

Excellent overview on BMI technology.

Less than a century ago, Hans Berger, a German psychiatrist, was placing silver foil electrodes on his patients’ heads and observing small ripples of continuous electrical voltage emerging from these. These were the first human brain waves to ever be recorded. Since Hans Berger’s first recordings, our knowledge on the brain structure and function has developed considerably. We now have a much clearer understanding of the neuronal sources that generate these electrical signals and the technology that is now available allows us to get a much denser and accurate picture of how these electrical signals change in time and across the human scalp.

The recording and analysis of brain signals has advanced to a level where people are now able to control and interact with devices around them with the use of their brain signals. The field of brain-computer interfaces has in fact garnered huge interest during the past two decades, and the development of low-cost hardware solutions together with the continuously evolving signal analysis techniques, have brought this technology closer to market than ever before.

In process similar to allergy testing, small quantities of different ‘barcoded’ drugs are tested inside patient’s tumor to determine effectiveness.

Excercise is the best low cost activity you can do as part of your personal longevity strategy. Here we see data showing it can improve resistance to oxidative stress.

Researchers digging deeper into the mechanisms by which exercise produces benefits have found that it improves the resistance of blood vessels to oxidative stress. With age the presence of oxidizing molecules and oxidative modification of proteins, preventing correct function, increases for reasons that include damage to mitochondria, the power plants of the cell. Oxidative damage to molecular machinery is somewhere in the middle of the chain of cause and effect that starts with fundamental forms of damage to cells and tissues and spirals down into age-related diseases. Near all of this oxidation is repaired very quickly, the damaged molecules dismantled and recycled, but in most contexts more of it over the long term is worse than less of it.

This is a big deal to children and adults impacted by cancer and chemo.

Devices reduce blood flow to hair follicles during chemotherapy treatments.

Wild.

The expression “once bitten, twice shy” is an illustration of how a bad experience can induce fear and caution. How to effectively reduce the memory of aversive events is a fundamental question in neuroscience. Scientists in China are reporting that by transplanting mouse embryonic interneurons into the brains of mice and combining that procedure with training to lessen fear, they can help to reduce the fear response. The study is being published December 8 in Neuron.

“Anxiety and fear-related disorders such as post-traumatic stress disorder [PTSD] cause great suffering and impose high costs to society,” says Yong-Chun Yu, a professor at the Institutes of Brain Science at Fudan University in Shanghai and the study’s senior author. “Pharmacological and behavioral treatments of PTSD can reduce symptoms, but many people tend to relapse. There’s a pressing need for new strategies to treat these refractory cases.”
