What are endocannabinoids?

Human body endocannabinoids network

Did you know our bodies make special substances to keep us balanced? Anandamide (AEA) and 2-arachidonoylglyerol (2-AG) are two key ones. They help manage our mood, appetite, and how we feel pain.

In the early 1990s, scientists found these special substances. Now, we know they are vital for making sure our body works just right. Anandamide and 2-AG play a big part in keeping us healthy and feeling well.

To understand more about endogenous cannabinoids, we should look at how they connect with our body’s receptors. These receptors, called CB1 and CB2, are key to the effects of endocannabinoids. They are found in our nervous system and in cells that help our immune system.

Scientists are very interested in the good effect endocannabinoids might have. They study how these substances can help us feel better emotionally, manage pain, remember things, and fight diseases. AEA and 2-AG do a lot to keep our body in balance.

Understanding endocannabinoids

The endocannabinoid system is a complex network in our body. It helps keep everything balanced by controlling many internal functions. At its core are endocannabinoids like anandamide and 2-AG. They link up with cannabinoid receptors everywhere in our nervous systems.

Anandamide and 2-AG act as natural triggers for these receptors. This was first shown by Matsuda L. A. and the team in 1990. They explained the building blocks and activity of these receptors. Later, Zygmunt P. M. et al. in 1999 found that special vanilloid receptors on nerve endings are also involved. They notice the signals from anandamide.

It’s key to understand how the receptors and endocannabinoids work together. This understanding can affect sleep, memory, and how our bodies fight sickness. Studies like the one by Wilson R. I. and Nicoll R. A. in 2001 show how they help in brain functions tied to learning and remembering things.

Endocannabinoids play a big part in keeping our body balanced. A study by Carrasco S. and Merida I. in 2007 looked at diacylglycerol, which helps make endocannabinoids. On the other hand, Reisenberg M. et al. in 2012 studied diacylglycerol lipases. These enzymes are key in breaking down endocannabinoids after they’ve done their job.

Understanding the detailed working in our ECS, including how receptors connect, is vital. It shows how our body fine-tunes its functions. This knowledge doesn’t only deepen our grasp of living in balance. It also may lead us to new ways to tackle health issues.

Components of the Endocannabinoid System

The endocannabinoid system (ECS) is a complex network that keeps the body balanced. It is made up of endocannabinoids, cannabinoid receptors, and certain enzymes. Together, these parts work to regulate various body functions.

Endocannabinoids

Endocannabinoids, like anandamide (AEA) and 2-arachidonyl glycerol (2-AG), are created when needed by the body. They are important for sending messages between cells. These messages affect things such as pain, mood, and how hungry we feel.

For example, anandamide helps control the flow of calcium in nerve cells. This makes it a key player in how we feel pain and other senses. 2-AG, on the other hand, fully activates certain receptors, showing its importance as well. The body’s levels and activity of these chemicals change based on what’s happening. This helps the body respond to different needs.

Cannabinoid receptors

Two main kinds of cannabinoid receptors are CB1 and CB2. They are found on cell surfaces all over the body’s nervous systems. CB1s are largely in the brain, while CB2s are mostly in immune cells.

These receptors interact with endocannabinoids to affect various things. For example, they help control pain and keep the immune system in check. Research also suggests that influencing CB2 receptors can help in reducing inflammation. This is by making immune cells interact less with certain blood vessels.

Enzymes

Enzymes like FAAH and MAGL help break down endocannabinoids after they’ve done their job. FAAH takes care of anandamide. This stops our ECS from getting overstimulated. On the flip side, MAGL processes 2-AG. It keeps the balance of this critical chemical in check. This helps keep everything running smoothly.

Here’s a summary of the main roles and functions of some important ECS parts:

ComponentRoles and functions
Anandamide (AEA)Regulation of pain, mood, and appetite; it’s a partial agonist that blocks calcium flow
2 Arachidonyl Glycerol (2-AG)Full agonist acting through CB2; it influences pain and immune reactions
CB1 receptorsMainly in the brain; they impact brain function
CB2 receptorsFound in immune cells; they adjust immune responses
FAAHBreaks down anandamide, controlling its effects
MAGLDegrades 2-AG, avoiding excessive stimulation

All these pieces work together to make the ECS and keep our body in balance. They are vital for maintaining our physical health.

What are endocannabinoids

Endocannabinoids are compounds made inside the body. They help control several body functions. In the early 90s, the endocannabinoid system was discovered. Researchers found it while studying THC, a well-known compound in cannabis. This discovery showed our bodies naturally produce anandamide (AEA) and 2-arachidonoylglyerol (2-AG).

The Endocannabinoid System (ECS) is made up of CB1 and CB2 receptors. These are located in different parts of the body. CB1 receptors are in the central nervous system. Meanwhile, CB2 receptors are in the peripheral nervous system.

The ECS influences many processes, including appetite, pain, mood, and more. Endocannabinoids are key to these functions. They are important in researching how cannabis affects us, including compounds like THC and CBD.

THC attaches to ECS receptors, producing effects like pain relief and increased hunger. CBD works differently. It helps endocannabinoids stay longer in the body by stopping their degradation.

Enzymes help manage the ECS by breaking down endocannabinoids. FAAH breaks down anandamide. MAGL is in charge of 2-AG. This process helps keep the ECS balanced and prevents overactivation.

Low levels of endocannabinoids may relate to certain health issues like migraines and irritable bowel syndrome. This connection suggests we can treat some conditions by focusing on the ECS. The discovery of the ECS has opened new doors in health and disease research, thanks to cannabis’s impact on our bodies.

THC and the ECS

THC is what makes you feel high from cannabis. It affects both CB1 and CB2 receptors in the ECS strongly. By doing this, THC can change how your brain and bodywork. It can cause effects like feeling happy or changing how you see things. THC can also help with pain and make you feel hungry by working with these receptors.

CBD and the ECS

CBD doesn’t make you feel high like THC does. It interacts with the ECS differently. CBD doesn’t directly attach to the ECS receptors. Instead, it helps the ECS work better by changing how some signals are sent in the body. It can help stop inflammation and lower stress. This shows how helpful CBD can be without making you feel high.

THC and CBD offer different ways to help with medical problems by working with the ECS. This shows that cannabis can be useful in many ways. Studying how THC and CBD work with the ECS could lead to new medical treatments. ECS modulation is still a very interesting topic for scientists to explore.
