Endocannabinoids and cannabinoid receptors are involved in the responses of animals to acute, repeated and variable stress [17] and there is good evidence that the cannabinoid receptors play a major role in modulating neurotransmitter release such as serotonin and dopamine among others [18].
Panel d shows retrograde axonal transport of BoNT to the dorsal horn of the spinal cord where it can block the release of pain-modulating neurotransmitters, such as glutamate, substance P, and calcitonin gene-related peptide (CGRP).
Although the true mechanism(s) of action is not yet clear, it can be speculated that L-NAME may exert its action indirectly by modulating neurotransmitters proposed to be involved in alcohol drinking and/or by influencing other neuronal factors, such as neuronal Ca2+ channels, which have been shown to be involved in alcohol drinking behavior.
St. John's wart lifts depression by modulating neurotransmitters that influence mood.
Experimental evidence indicates that GRO- β, also known as the chemokine CXCL2, may mediate varied functions, such as attracting neutrophils to sites of inflammation, regulating angiogenesis, and modulating neurotransmitter release [ 24– 26].
They have shown that the 'memory fields' of the prefrontal cortex are modulated by neurotransmitters such as dopamine serotonin and gamma-amino-butyric acid (GABA) in different ways [ 16- 18].
A physiological action consisting of the capability of modulating neurotransmitter release and/or action.
The report goes on to look at the effects of ampakines, a class of drugs that modulate neurotransmitters in the brain, to remove the effects of sleep deprivation.
AEA is capable of inhibiting capsaicin-evoked CGRP release from terminals of primary afferent fibers of spinal cord to modulate neurotransmitters release [36].
B. monniera treatment modulates various neurotransmitters such as acetylcholine (ACh), serotonin (5-hydroxytryptamine, 5-HT), gamma amino butyric acid (GABA), glutamate (Glu) and dopamine (DA) at different brain regions to enhance the cognitive functions [16, 18, 19, 20, 21, 22, 23, 24].
