First attempt- do not use Flashcards
Module 1 - Introduction to the Endocannabinoid System
what is the role of the veterinary team?
Prevention of harm
patient advocacy
maintain and strengthen the VCPR
Scientific and medical advancement
ECS: a system of balance
inter and intra-cellular communication
regulation between cell system
maintain whole-body homeostasis
ECS consists of:
Cannabinoid receptors
Cannabinoids
Enzymes
Cannabinoid receptor Characteristics
G-protein coupled receptors
- membrane-bound
- Conformation change with ligand binding
- activation results in intracellular signaling
CB1 receptors are located?
Primarily within the nervous system
CB2 receptors are located?
Primarily within peripheral tissue , immune system
CB1 receptor target, name a few?
motor activity thinking appetite pain perception immune cells motor coordination short term memory
CB2 receptors influence most of the body, name a few?
Gut, kidneys, pancreas, adipose tissue, skeletal muscle, bone, eye, tumors, repo system, immune system, respiratory tract, skin, CNS, cardiovascular system, liver
CB1 receptor is located where on the neuron?
Pre-synaptic neuron
Glutamate =
Excitatory signal
GABA =
Inhibitory signal
Retrograde feedback results in diverse effects
Depolarization-induced suppression of excitation (DSE)
inhibition of Glutamate
Depolarization-induced suppression of inhibition (DSI)
Inhibition of GABA
CB1 receptors =
Neuro-modulatory
Endocannabinoids (eCBs)
Anandamide (AEA)
2-arachidonoylglycerol (2-AG)
eCBS are lipid-derived, enzyme activated and “On Demand”, inactive precursors are?
NAPE-PLD > AEA
DAGLa > 2-AG
AEA is degraded by?
FAAH- Fatty acid amide hydrolase
2-AG is degraded by?
MGL- Monoglyceral lipase
Exogenous Cannabinoids are?
THC- delta-9-tetrahydrocannabinol
-direct agonist
CBD- Cannabidinol
-eCB reuptake inhibiton
There’s so MUCH MORE than CBD and THC
Cannabis plants produce over 180 cannabinoids, terpenes, and flavinoids
CB2 receptor density can increase up to 100x in response?
to inflammation, Allows for targeting of injury
CB2 receptors =
immuno-modulatory
Temporal control
retrograde feedback (CB1) on-demand production/rapid degradation (eCBs)
Spatial Control
pre-synaptic location (CB1)
increase CB2 receptors in injury
Phyto-cannabinoids and synthetic cannabinoids are examples of?
exogenous cannabinoids
