Most cancers & the CB2 Receptor

The cannabinoid receptor CB1, main goal of THC within the mind, is understood for mediating the hashish excessive. And its counterpart CB2, primarily expressed in immune cells all through the physique, is known to play an vital function in inflammatory processes. These abstractions are correct so far as they go, however as with something associated to the endocannabinoid system, actuality is much extra advanced.

Challenge CBD’s latest article on the passing of Raphael Mechoulam famous that the esteemed scientist believed CB2 must be a spotlight of future cannabinoid science. The CB2 receptor interacts with THC, CBD, endocannabinoids, and different compounds in a large number of organs together with pores and skin and bone.

Current analysis – together with papers co-authored by Mechoulam properly into his 80s – has confirmed that aberrant CB2 signaling is implicated in a raft of autoimmune, neurodegenerative, metabolic, and psychiatric issues. CB2 can also be an more and more scorching matter in most cancers analysis.

On this two-part sequence, Challenge CBD will discover a number of the newest research and what they reveal about what we all know – and nonetheless don’t know – about this ubiquitous, considerably mysterious cell receptor.

This week: most cancers. Subsequent week: cognitive and temper issues, together with a few of Mechoulam’s ultimate work earlier than his dying in March on the age of 92.

Prostate Most cancers & a New CB2 Ligand

Three research from the primary few months of 2023 probe the operate of CB2 in three totally different most cancers fashions. Whereas their findings are advanced and never essentially conclusive, they contribute to a rising physique of data concerning the potential efficacy of cannabinoids in most cancers therapy.

A paper printed in February within the Worldwide Journal of Molecular Sciences1 presents two insights for the worth of 1: first, one other take a look at how the CB2 receptor capabilities in a mobile mannequin of most cancers; and second, new proof {that a} compound known as 3-3′-Diindolylmethane (DIM) – current in cruciferous greens corresponding to cauliflower, cabbage, broccoli, Brussels sprouts, and various leafy greens – exerts anti-cancer results by means of the CB2 receptor.

By testing DIM on two totally different human prostate most cancers cell traces, the Italy- and UK-based researchers noticed that the compound activated naturally expressed CB2 receptors in each traces – and that in a single, often known as “PC3,” CB2 activation led to cell dying, an impact that was reversed when the researchers blocked the CB2 receptor with an antagonist.

DIM was already identified to have an anti-cancer impact extra broadly. What had not been beforehand noticed, the authors observe, is CB2’s function in mediating this impact in a human most cancers cell line. “We will conclude that DIM is a CB2 receptor ligand with a possible anti-prostate most cancers impact,” they write.

If true, cruciferous greens be a part of saffron, black pepper, cloves, oregano, and another spices as meals containing compounds that work together with the CB2 receptor in useful methods.

However don’t head to the marketplace for a cartload of cauliflower and cabbage simply but. The concentrations of DIM used within the research are too excessive to be obtained by means of weight loss plan alone, the authors observe, and administration by dietary supplements could also be required.

Colon Most cancers: Case Closed?

A second February 2023 research within the Worldwide Journal of Molecular Sciences2 involves the same conclusion relating to CB2’s function in colon most cancers. Researchers in Israel investigated how the CB2 receptor functioned in a mouse mannequin of colon most cancers (using “knockout” mice lacking the receptor altogether), they usually analyzed genomic knowledge in a big human inhabitants to find out the connection between CB2 variants and colon most cancers incidence.

In each instances, the authors write, their findings point out that “endogenous CB2 activation can modulate the immune response and consequently scale back tumorigenesis” and that “CB2 protects towards the event of colon most cancers.”

But regardless of their seemingly unambiguous findings, the authors additionally acknowledge that earlier research have come to very totally different conclusions concerning the function of CB2 in most cancers.

CB2 has been investigated in a number of most cancers sorts and fashions of irritation,” they write, “and there are controversial outcomes relating to the impact on tumor development.” For instance, previous research have discovered that CB2 expression is related to a poor prognosis in people; that CB2 antagonists, or blockers, suppress tumor development; that CB2 activation promotes tumor development in fashions of colon most cancers; and that CB2 agonists inhibit tumor development. The researchers attribute this ambiguity to variations in animal most cancers fashions and most cancers cell traces.

Lung Most cancers: A Completely different Reply

Positive sufficient, a special research printed a month earlier in Frontiers in Immunology3 utilizing a special mouse mannequin of non-small cell lung most cancers appears to indicate one thing else altogether.

Inside knockout mice poor of CB2 within the “tumor microenvironment” – the traditional cells, molecules, and blood vessels that encompass a tumor cell, together with immune cells expressing excessive ranges of CB2 – a crew of Austria-based researchers noticed a discount in tumor burden relative to “wild-type” mice. Additionally they discovered that CB2-deficient mice responded considerably higher to a type of immunotherapy often known as anti-PD1.

Collectively, these findings point out that CB2 receptors within the tumor microenvironment of non-small cell lung most cancers “might act as an immunosuppressor … thereby selling tumor development.”

You learn that proper: the other of what the opposite two papers discovered. Be that as it might, it nonetheless appears clear sufficient that CB2 modulates mobile immune response in methods immediately related to most cancers development – and that the medical implications of this hyperlink nonetheless have to be labored out.
