What functions are regulated by CB2 receptors?

CB2 receptors, which are part of the endocannabinoid system, primarily play a role in the immune system and various physiological processes related to the regulation of energy balance, development, and metabolism. They are expressed in various tissues, including the brain, but their predominant functions involve modulating inflammatory responses and influencing metabolic processes.

In the context of energy balance, CB2 receptors can affect how the body stores and uses energy, impacting everything from appetite regulation to fat metabolism. Their involvement in development also ties them to processes that influence cell differentiation and growth. Consequently, they are crucial for maintaining homeostasis within the body.

Other options, while they may be linked to cannabinoid interactions or different receptor types, do not capture the specific functions of CB2 receptors as accurately as the regulation of energy balance, development, and metabolism does. Memory and learning, emotion and mood stabilization, as well as muscle coordination and agility are more closely associated with CB1 receptors or other neurotransmitter systems, but the CB2 receptor functions are primarily aligned with metabolic and immune system processes.
