Immune cells thought to trigger dementia actually PROTECT against it

Posted by in categories: biotech/medical, neuroscience

A specific type of immune cell, called microglia (green) can help contain amyloid plaques (magenta), the key hallmark of Alzheimer’s disease, thus limiting their damage to surrounding brain cells.

But, Dr Jaime Grutzendler, associate professor of neurology and neuroscience at Yale, said that is no longer thought to be the case, and should signal a new.

He said: ‘It suggests we should be enhancing the function of these immune cells, not trying to suppress it.’

Here’s How to Prevent Half of Cancer Deaths

Posted by in categories: biotech/medical, genetics

Harvard you’re wrong. Why? Harvard needs to explain to all the families with genetic mutations tied to various types of cancer, cancer survivors who carry a genetic mutation, or the workers who were exposed at work to radiation or carcinogens how their smoking caused their cancer when they never smoked in their entire life. However, how do you explain that to the countless million patients, survivors, and loved ones who lost someone to cancer that never smoked or were exposed to smoking.


As many as 40 percent of cancer cases, and half of cancer deaths, come down to things people could easily change, researchers said Thursday.

While Americans often worry about whether chemicals, pollution or other factors out of their control cause cancer, the new analysis shows otherwise: People are firmly in charge of much of their own risk of cancer.

Multicellular Life Was Caused By The Same Gene That Suppresses Cancer

Posted by in categories: biotech/medical, evolution

Biologists have identified the one gene that caused the evolution of single-celled organisms into multicellularity, debunking previous theories that several genes were at play. The gene retinoblastoma is also the same gene that is found to be defective in cancer patients, and suppresses tumors.

Gene helps prevent heart attack, stroke — and may offer way to block effects of aging

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

CHARLOTTESVILLE, Va., May 17, 2016 — A gene that scientific dogma insists is inactive in adults actually plays a vital role in preventing the underlying cause of most heart attacks and strokes, researchers at the University of Virginia School of Medicine have determined. The discovery opens a new avenue for battling those deadly conditions, and it raises the tantalizing prospect that doctors could use the gene to prevent or delay at least some of the effects of aging.

“Finding a way to augment the expression of this gene in adult cells may have profound implications for promoting health and possibly reversing some of the detrimental effects with aging,” said researcher Gary K. Owens, PhD, director of UVA’s Robert M. Berne Cardiovascular Research Center.

Size of Brain Region May Impact How Well Exposure Therapy Works for PTSD

Posted by in categories: biotech/medical, health, neuroscience

Interesting read on PTSD. Wonder how much this plays into DARPA’s own research around memory removal on PTSD patients. hmmm.


New research suggests that PTSD patients with a larger region of the brain that helps distinguish between safety and threat are more likely to respond to exposure-based therapy.

The study expands upon prior research that discovered having a smaller hippocampus is associated with increased risk of PTSD.

How nanotechnology could detect and treat cancer

Posted by in categories: biotech/medical, nanotechnology, neuroscience

The crew of the Proteus has one desperate chance to save a man’s life. Shrunk to the size of a large bacterium, the submarine contains a team of scientists and physicians racing to destroy a blood clot in the brain of a Soviet defector. The group journeys through the body, evading giant white blood cells and tiny antibodies while traveling through the heart, the inner ear and the brain to reach and destroy the blockage.

Although events in the film Fantastic Voyage were far-fetched when it was released in 1966, they’re now being realized every day in labs around the world, particularly in cancer treatment. A growing field called nanotechnology is allowing researchers to manipulate molecules and structures much smaller than a single cell to enhance our ability to see, monitor and destroy cancer cells in the body.

Tens of thousands of patients have already received chemotherapy drugs delivered by nanoparticles called liposomes, and dozens of other approaches are currently in clinical trials. Within the next five to 10 years, our bodies’ biggest defenders may be tinier than we could have ever imagined.

The bionic skin that can feel a tumor

Posted by in categories: biotech/medical, cyborgs, neuroscience, transhumanism

Nice!


Our skin is our largest organ. A gateway between our brain and the rest of the world.

Imagine then a scene where skin could communicate what’s going on inside a human body. It could inform surgeons, provide alerts when our body is about to fall ill, or even diagnose diseases inside another human being, simply through the sense of touch.

An Interview with the Advocates of the Major Mouse Testing Program Team

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

New MMTP Interview on Fightaging! discussing longevity, advocacy and the urgent need to support research!


By way of following on from today’s AMA over at /r/futurology, I recently had the chance to ask a few questions of the Major Mouse Testing Program (MMTP) volunteers, a mix of scientists and advocates who aim to do their part to speed up progress towards effective treatments for the causes of aging. The group formed six months ago or so, and are presently seeking funds for their first mouse studies through crowdfunding with the Lifespan.io organization. The initial focus is on senolytic treatments capable of removing senescent cells from old tissues. I encourage you all to take a look at the details of their research proposal.

Growth in the number of dysfunctional, senescent cells is a contributing cause of degenerative aging, involved in the progression and pathology of all of the common age-related diseases. A growing body of evidence supports the outright removal approach as a way to minimize or eliminate this portion of the aging process. Unfortunately there is — as ever in the aging research field — a paucity of funding and always the need for more and better animal data in order to pull in other players with deep pockets. At this stage in the progression from laboratory to clinic, prior to the involvement of any large institutions or companies, all such efforts are important work. I’m pleased to have been able to contribute to this Major Mouse Testing Program fundraiser, and hope to see great things from this group in the future.
