Scientific research by two La Jolla establishments are specializing in parts of hashish as remedies for illnesses together with Alzheimer’s illness and ache from sports activities accidents.
Salk Institute for Organic Research
A long time of analysis on medical hashish has targeted on the compounds THC and CBD in scientific purposes. However much less is understood concerning the therapeutic properties of cannabinol (CBN). However a brand new examine by scientists on the Salk Institute for Organic Research signifies that CBN can shield nerve cells from oxidative harm, a serious pathway to cell loss of life.
The findings, printed on-line final month by the journal Free Radical Biology and Drugs, recommend CBN has the potential for treating age-related neurodegenerative ailments akin to Alzheimer’s.
“We’ve discovered that cannabinol protects neurons from oxidative stress and cell loss of life, two of the key contributors to Alzheimer’s,” stated examine senior creator Pamela Maher, a analysis professor and head of Salk’s Mobile Neurobiology Laboratory. “This discovery may sooner or later result in the event of recent therapeutics for treating this illness and
different neurodegenerative problems, like Parkinson’s illness.”

CBN is a compound of the hashish plant that’s molecularly just like tetrahydrocannabinol (THC), however in contrast to THC, it’s not psychoactive. It’s additionally much less closely regulated by the U.S. Meals and Drug Administration.
Earlier analysis by Maher’s lab decided that CBN had neuroprotective properties, but it surely wasn’t clear the way it labored. The brand new examine explains the mechanism via which CBN protects mind cells from harm and loss of life.
Maher’s workforce appeared on the strategy of oxytosis, which is assumed to happen within the growing older mind. Rising proof means that oxytosis could also be a reason behind Alzheimer’s illness. Within the examine, the scientists handled nerve cells with CBN after which launched an agent to stimulate oxidative harm.
They additional discovered that the CBN labored by defending mitochondria, the cell’s powerhouses, throughout the neurons. In broken cells, oxidation triggered the mitochondria to twist up — a change that additionally has been seen in growing older cells taken from the brains of individuals with Alzheimer’s. Treating cells with CBN prevented the mitochondria from curling up and saved them functioning properly, in accordance with the examine.

To substantiate the interplay between CBN and mitochondria, researchers replicated the experiment in nerve cells that had the mitochondria eliminated. In these cells, CBN not demonstrated its protecting impact.
“We had been capable of straight present that upkeep of mitochondrial perform was particularly required for the protecting
results of the compound,” Maher stated.
In one other key discovering, researchers reported that CBN didn’t activate cannabinoid receptors, that are required for cannabinoids (compounds present in hashish) to supply a psychoactive response. Thus, CBN therapeutics would work with out inflicting the individual to grow to be “excessive.”
“CBN just isn’t a managed substance like THC … and proof has proven that CBN is protected in animals and people. And since CBN works independently of cannabinoid receptors, CBN may additionally work in all kinds of cells with ample therapeutic potential,” stated first creator Zhibin Liang, a postdoctoral fellow within the Maher lab.
As a subsequent step, Maher’s workforce is working to see if it might probably reproduce its leads to a preclinical mouse mannequin.
UC San Diego
The Nationwide Soccer League has awarded $1 million to 2 medical analysis groups — together with one at UC San Diego — to check the influence of the non-intoxicating hashish element cannabidiol (CBD) on ache administration and restoration from sports-related accidents.
UCSD and the College of Regina in Canada had been chosen from amongst 106 submissions for analysis proposals executed by the NFL-NFLPA Joint Ache Administration Committee, with UCSD’s workforce assessing the therapeutic potential of
hashish for “reduction of post-competition soft-tissue harm ache in elite athletes.”
In line with an NFL assertion, athletes outdoors the NFL will use vaporized remedies following game-related accidents, with the outcomes monitored through telephone apps. Collaborating athletes will obtain remedies of both 4 % THC, 12 % CBD, a mix of CBD and THC, or a placebo, in accordance with UCSD. The college stated that whereas no conclusions may be drawn till the examine is accomplished, investigators imagine the THC and THC/CBD combos will show to be the superior remedies.
In line with a UC San Diego Well being assertion, skilled rugby gamers had been chosen for the preliminary trial, which not solely will consider ache reduction and restoration but in addition any results on bodily perform, sleep, cognition and temper.
“An innovation of this analysis is utilizing a real-world mannequin of the NFL’s aggressive harm burden with a gaggle of elite athletes who expertise related accidents,” stated Thomas Marcotte, a professor of psychiatry at the united states College of Drugs. “It’s a first-of-its-kind randomized trial to look at the doable sensible efficacy of cannabinoids on post-competition ache.” ◆
