Biosynthesis and Extracellular Concentrations of N, N-dimethyltryptamine (DMT) in Mammalian Brain

Posted by in category: neuroscience

Year 2019 Dmt actually produced naturally in the human brain scientists are now believing it could be the spirit molecule of the human being which is also found in mice.


N, N-dimethyltryptamine (DMT), a psychedelic compound identified endogenously in mammals, is biosynthesized by aromatic-L-amino acid decarboxylase (AADC) and indolethylamine-N-methyltransferase (INMT). Whether DMT is biosynthesized in the mammalian brain is unknown. We investigated brain expression of INMT transcript in rats and humans, co-expression of INMT and AADC mRNA in rat brain and periphery, and brain concentrations of DMT in rats. INMT transcripts were identified in the cerebral cortex, pineal gland, and choroid plexus of both rats and humans via in situ hybridization. Notably, INMT mRNA was colocalized with AADC transcript in rat brain tissues, in contrast to rat peripheral tissues where there existed little overlapping expression of INMT with AADC transcripts.

Drug treatment slows neurodegenerative disease in mice

Posted by in categories: biotech/medical, neuroscience

Scientists have found a new drug treatment that can slow the progression of neurodegenerative disease in mice. The breakthrough research may offer fresh hope in tackling currently untreatable conditions such as Alzheimer’s disease.

The study—led by researchers at the University of Glasgow’s new Advanced Research Center (ARC) and published today in Science Signaling —found that by using a novel , which selectively activates a brain protein called the M1-receptor, the lifespan of mice suffering from neurodegeneration could be extended. The M1-receptor is a key brain protein, involved in memory and learning in people, and is an important potential target for neurodegenerative disease treatment.

Mind over matter: Scientists unlock regeneration mechanism for brain injury

Posted by in categories: biotech/medical, neuroscience

Basically this is one of the cure all options for thousands of brain disorders.


Researchers in Portugal have discovered a new collaborative mechanism that unveils how neural stem cells sense injury and communicate for tissue repair, moving science closer to boosting neuron regeneration after brain damage.

Stroke and traumatic brain injury can permanently damage neurons and, depending on injury site, patients may experience long-term impairments of critical motor or cognitive functions. For this reason, the brain has a reserve of special cells—known as neural stem cells—that can partially activate after tissue damage.

Clinical Trial Examines Synthetic Psilocybin as a Treatment for Severe Depression

Posted by in categories: biotech/medical, neuroscience

Individuals suffering from severe depression may find relief from just a single dose of a synthetic version of psilocybin, or “magic mushrooms,” according to a new study published this week.

The findings, which were published Wednesday by The New England Journal of Medicine, come from a double-blind trial involving 233 “randomly assigned adults with treatment-resistant depression [who received] a single dose of a proprietary, synthetic formulation of psilocybin at a dose of 25 mg, 10 mg, or 1 mg (control), along with psychological support.”

“In this phase 2 trial involving participants with treatment-resistant depression, psilocybin at a single dose of 25 mg, but not 10 mg, reduced depression scores significantly more than a 1-mg dose over a period of 3 weeks but was associated with adverse effects,” the authors wrote in their conclusions, adding that “larger and longer trials, including comparison with existing treatments, are required to determine the efficacy and safety of psilocybin for this disorder.”

Rare success for Alzheimer’s research unlocks hope for future therapies

Posted by in categories: biotech/medical, neuroscience

CHICAGO, Nov 29 (Reuters) — The first big breakthrough in 30 years of Alzheimer’s research is providing momentum for clinical trials of “cocktail” treatments targeting the two hallmark proteins associated with the mind-robbing disease, according to interviews with researchers and pharmaceutical executives.

Scientists hail major breakthrough in fight against Alzheimer’s as drug proven to slow disease

Posted by in categories: biotech/medical, neuroscience

‘This is the first drug that provides a real treatment option,’ says leading researcher Scientists are hailing a historic step in the fight against Alzheimer’s, after a drug was proven to slow the disease in long-awaited clinical trials. The breakthrough comes after decades of failed attempts to find a way to do so, and has prompted hope among experts that it could eventually pave the way for treatments which could ultimately lead to a cure.
