“We investigated the effects of S-777469 (1-[[6-Ethyl-1-[4-fluorobenzyl]-5-methyl-2-oxo-1, 2-dihydropyridine-3-carbonyl]amino]-cyclohexanecarboxylic acid), a novel cannabinoid type 2 receptor (CB2) agonist, on 1-fluoro-2,4-dinitrobenzene (DNFB)-induced ear inflammation and mite antigen-induced dermatitis in mice. The oral administration of S-777469 significantly suppressed DNFB-induced ear swelling in a dose-dependent manner. In addition, S-777469 significantly alleviated mite antigen-induced atopic dermatitis-like skin lesions in NC/Nga mice. A histological analysis revealed that S-777469 significantly reduced the epidermal thickness and the number of mast cells infiltrating skin lesions. We demonstrated that S-777469 inhibited mite antigen-induced eosinophil accumulation in skin lesions and an endogenous CB2 ligand, 2-arachidonoylglycerol (2-AG)-induced eosinophil migration in vitro. Moreover, we confirmed that 2-AG levels significantly increased in skin lesions of mite antigen-induced dermatitis model. Together, these results suggest that S-777469 inhibits skin inflammation in mice by blocking the activities of 2-AG.” https://www.ncbi.nlm.nih.gov/pubmed/28214870]]>

Brain cannabinoid systems as targets for the therapy of neurological disorders.
“Unprecedented developments in cannabinoid research within the past decade include discovery of a brain (CB1) and peripheral (CB2) receptor; endogenous ligands, anandamide, and 2-arachidonylglycerol; cannabinoid drug-induced partial and inverse agonism at CB1 receptors, antagonism of NMDA receptors and glutamate, and antioxidant activity; and preferential CB1 receptor localization in areas subserving spasticity, pain, abnormal involuntary movements, seizures, and amnesia. These endogenous structures and chemicals and mechanisms are potentially new pathophysiologic substrates, and targets for novel cannabinoid treatments, of several neurological disorders.” https://www.ncbi.nlm.nih.gov/pubmed/9974182

Cannabinoid-based medicines for neurological disorders–clinical evidence.
“Whereas the cannabis plant has a long history of medicinal use, it is only in recent years that a sufficient understanding of the pharmacology of the main plant constituents has allowed for a better understanding of the most rational therapeutic targets.
The distribution of cannabinoid receptors, both within the nervous system and without, and the development of pharmacological tools to investigate their function has lead to a substantial increase in efforts to develop cannabinoids as therapeutic agents.
Concomitant with these efforts, the understanding of the pharmacology of plant cannabinoids at receptor and other systems distinct from the cannabinoid receptors suggests that the therapeutic applications of plant-derived cannabinoids (and presumably their synthetic derivatives also) may be diverse.
This review aims to discuss the clinical evidence investigating the use of medicines derived, directly or indirectly, from plant cannabinoids with special reference to neurological disorders.
Published studies suggest that the oral administration of cannabinoids may not be the preferred route of administration and that plant extracts show greater evidence of efficacy than synthetic compounds. One of these, Sativex (GW Pharmaceuticals), was approved as a prescription medicine in Canada in 2005 and is currently under regulatory review in the EU.” https://www.ncbi.nlm.nih.gov/pubmed/17952657

“Marijuana is a complex substance containing over 60 different forms of cannabinoids, the active ingredients. Cannabinoids are now known to have the capacity for neuromodulation, via direct, receptor-based mechanisms at numerous levels within the 
“As a consequence of an increasingly aging population, the number of people affected by neurodegenerative disorders, such as Alzheimer’s disease, Parkinson’s disease and Huntington’s disease, is rapidly increasing. Although the etiology of these diseases has not been completely defined, common molecular mechanisms including neuroinflammation, excitotoxicity and mitochondrial dysfunction have been confirmed and can be targeted therapeutically.
Moreover, recent studies have shown that endogenous 
“The hallmark of vaccines is their ability to prevent the spread of infectious pathogens and thereby serve as invaluable public health tool. Despite their medical relevance, there is a gap in our understanding of the physiological factors that mediate innate and adaptive immune response to vaccines.
The endocannabinoid (eCB) system is a critical modulator of homeostasis in vertebrates. Our results indicate that macrophages and dendritic cells produce the endocannabinoid, 2-arachidonoyl-sn-glycerol (2-AG) upon antigen activation.
We have also established that 2-AG levels are upregulated in the serum and in the lymph node of mice during vaccination.
We hypothesized that the intrinsic release of eCBs from immune cells during activation by pathogenic antigens mitigate inflammation, but also suppress overall innate and adaptive immune response.
Here we demonstrate, for the first time, that transient administration of the
