Let's relate this to brain recovery and see if our incompetent stroke medical 'professionals' can understand why to research this! 9 years of incompetence already! WAY TO GO; KEEP UP THE GOOD WORK!
“Zombie” Aging Cells May Speed Up Brain Decline October 2024
Since nothing will occur your children and grandchildren will suffer the consequences of such incompetence!
Send me hate mail on this: oc1dean@gmail.com. I'll print your complete statement with your name and my response in my blog. Or are you afraid to engage with my stroke-addled mind? No excuses are allowed! You're medically trained; it should be simple to precisely state
EXACTLY WHAT YOU ARE DOING that is competent in getting to 100% RECOVERY with NO EXCUSES! Your definition of competence in stroke is obviously much lower than stroke survivors' definition of your competence! Swearing at me is allowed, I'll return the favor. Don't even attempt to use the excuse that brain research is hard.
The latest here:
Clearing Zombie Cells Eases Back Pain
Summary: A new preclinical study has found that two drugs—o-Vanillin and RG-7112—can clear “zombie cells” from spinal discs, potentially treating the root cause of chronic low back pain. These senescent cells accumulate with age or injury and cause inflammation, pain, and tissue damage.
When administered orally to mice, the drugs reduced inflammation, relieved pain, and even reversed disc damage, with the greatest benefits seen when both drugs were combined. This groundbreaking approach could transform treatment for millions with chronic back pain by targeting the source, not just the symptoms.
Key Facts:
- Root Cause Targeted: Zombie-like senescent cells drive inflammation in spinal discs.
- Dual Drug Effect: o-Vanillin and RG-7112 worked best when used together.
- Oral Success: Drugs delivered by mouth reached hard-to-access spinal discs and reversed damage.

In a preclinical study led by McGill University researchers, two drugs targeting “zombie cells” have been shown to treat the underlying cause of chronic low back pain. The condition affects millions of people worldwide.
Current treatments manage symptoms through painkillers or surgery, without addressing the root cause.
“Our findings are exciting because it suggests we might be able to treat back pain in a completely new way, by removing the cells driving the problem, not just masking the pain,” said senior author Lisbet Haglund, a Professor in McGill’s Department of Surgery and Co-director of the Orthopaedic Research Laboratory at the Montreal General Hospital (MUHC).
The work was conducted by McGill’s Alan Edwards Centre for Research on Pain at the Montreal General Hospital, part of the MUHC.
Treating pain at the source
Senescent cells, often called zombie cells, build up in the spinal discs as people age or when discs are damaged. Instead of dying off like normal cells, these aging cells linger and cause inflammation, pain and damage to the spine.
To explore a potential solution, the research team administered two drugs orally to mice: o-Vanillin, a natural compound, and RG-7112, an FDA-approved cancer drug. They were administered together as well as separately.
They found the drugs could clear zombie cells from the spine, reduce pain and inflammation, and slow or even reverse damage to spinal discs after eight weeks of treatment. Each of the drugs had a beneficial effect, but the impact was greatest when they were administered together.
“We were surprised that an oral treatment could reach the spinal discs, which are hard to access and present a major hurdle in treating back pain,” said Haglund. “The big question now is whether these drugs can have the same effect in humans.”
A natural compound’s surprising potential
Notably, o-Vanillin wasn’t originally intended to be part of the study and was included almost by chance. Haglund explained that while testing other drugs, her team decided to add the compound, derived from turmeric and known for its anti-inflammatory properties, to see whether it might be effective in this situation.
The results offer some of the first evidence that o-Vanillin can clear out zombie cells. Analogs of RG-7112 are known to do this in osteoarthritis and cancer research, but had not been used to treat back pain.
Looking ahead, Haglund’s team will work to improve o-Vanillin’s structure to help it stay in the body longer to become even more effective. They believe these drugs have the potential to treat other age-related diseases driven by senescent cells, such as arthritis or osteoporosis.
(So your researchers will need to figure out how to use nanocarriers to deliver this past the blood brain barrier. Or maybe nasal delivery. If they don't know how to deliver drugs to the brain, they are totally fucking incompetent!
