How do plants produce cannabinoids?
Cannabinoids like THCA (which converts to THC with heat and over time) are produced in tiny glands on the surface of the plant called trichomes. Trichomes appear on many plant species and serve to protect in a variety of ways, including: Defending against insect herbivores.
How did we get cannabinoid receptors?
Cannabinoid receptors are activated by cannabinoids, generated naturally inside the body (endocannabinoids) or introduced into the body as cannabis or a related synthetic compound. Similar responses are produced when introduced in alternative methods, only in a more concentrated form than what is naturally occurring.
How did the endocannabinoid system evolve?
Endocannabinoids are an ancient chemistry that evolved in nerve cells as part of the response to certain kinds of stress. This protective response had its power extended twice, with the CB1 and CB2 receptors. So this is a simple story of three steps — the cell chemistry, then CB1, and CB2.
What is the result of activating the cannabinoid receptor?
Activation of CB1 receptors inhibits glutamatergic synaptic transmission. Both endogenous and synthetic cannabinoid receptor agonists activate potently and stereoselectively a presynaptic CB1 receptor that inhibits the release of glutamate via an inhibitory G-protein in cultured hippocampal pyramidal neurons (34-36).
What plants produce cannabinoids?

- Black Truffles (Tuber melanosporum)
- Chinese Rhododendron.
- Electric Daisy (Acmella Oleracea)
- Japanese Liverwort (Radula marginata)
What is the endocannabinoid system and what does it do?
The endocannabinoid system (ECS) is a biological system in the body that helps regulate and balance key bodily functions. Research suggests that the ECS may be a potential therapeutic target in numerous physiological conditions such as: energy balance. appetite stimulation.
What receptors do cannabinoids target?
Many of the effects of cannabinoids and endocannabinoids are mediated by two G protein-coupled receptors (GPCRs), CB(1) and CB(2), although additional receptors may be involved. CB(1) receptors are present in very high levels in several brain regions and in lower amounts in a more widespread fashion.
When was the cannabinoid system discovered?
On March 24, 1992, Lumír Hanuš, a Czech analytical chemist working in Israel with American pharmacologist William Devane, isolated the first known endocannabinoid in the human brain.
What does the cannabinoid system do?
The endocannabinoid system is a molecular system responsible for regulating and balancing many processes in the body, including immune response, communication between cells, appetite and metabolism, memory, and more.
When did the endocannabinoid system evolve?
By comparing the genetics of cannabinoid receptors in different species, scientists estimate that the endocannabinoid system evolved in primitive animals over 600 million years ago.
What receptors are stimulated by cannabinoids?
These activate the cannabinoid 1 receptor (CB1) receptor in the central nervous system (CNS). The result can include modulation of adenylate cyclase activity to inhibit cAMP accumulation, voltage-gated calcium channels (VGCC), K+ channels and neurotransmitter release in presynaptic excitatory and inhibitory synapses.
What do the cannabinoid receptors do?
Cannabinoid receptors have been implicated in diverse physiological and pathophysiological roles in the body, including regulation of mood, appetite, pain sensation, vascular and nonvascular smooth muscle tone, and immune function.
