“Systemic lupus erythematosus (SLE) is a systemic autoimmune disease, characterized by loss of tolerance toward self nuclear Ags. Systemic induction of type I IFNs plays a pivotal role in SLE, a major source of type I IFNs being the plasmacytoid dendritic cells (pDCs). Several genes have been linked with susceptibility to SLE in genome-wide association studies. We aimed at exploring the role of one such gene, α/β-hydrolase domain-containing 6 (ABHD6), in regulation of IFN-α induction in SLE patients. We discovered a regulatory role of ABHD6 in human pDCs through modulating the local abundance of its substrate, the endocannabinoid 2-arachidonyl glycerol (2-AG), and elucidated a hitherto unknown cannabinoid receptor 2 (CB2)-mediated regulatory role of 2-AG on IFN-α induction by pDCs. We also identified an ABHD6High SLE endophenotype wherein reduced local abundance of 2-AG relieves the CB2-mediated steady-state resistive tuning on IFN-α induction by pDCs, thereby contributing to SLE pathogenesis.”

“Multiple sclerosis (MS) is an autoimmune disease leading to the destruction of myelin with consequent axonal degeneration and severe physical debilitation. The disease can be treated with immunosuppressive drugs that alleviate the symptoms and retard disease aggravation. One such drug in clinical use is glatiramer acetate (Copaxone).
The non-psychotropic immunosuppressive 
“The gut microbiota plays a fundamental role on the education and function of the host immune system.
Immunological dysregulation is the cause of numerous human disorders such as autoimmune diseases and metabolic disorders frequently associated with inflammatory processes therefore is critical to explore novel mechanisms involved in maintaining the immune system homeostasis.

“Multiple sclerosis (MS) is a chronic debilitating autoimmune disease without a cure. While the use of marijuana cannabinoids for MS has recently been approved in some countries, the precise mechanism of action leading to attenuate neuroinflammation is not clear. We used experimental autoimmune encephalomyelitis (EAE), a murine model of MS, to explore the anti-inflammatory properties of 
“Systemic sclerosis (SSc) or scleroderma is a chronic multi-organ autoimmune disease characterized by vascular, immunological, and fibrotic abnormalities.
The etiology of SSc is unknown, but there is growing evidence that dysfunction of the endocannabinoid system (ECS) plays a critical role in its development.
Since the semi-synthetic cannabinoquinoid VCE-004.8 could alleviate bleomycin (BLM)-induced skin fibrosis, we have investigated an oral lipid formulation (EHP-101) of this dual PPARγ/CB2 receptors activator for the prevention of skin- and lung fibrosis and of collagen accumulation in BLM challenged mice.
Taken together, these data provide a rationale for further developing VCE-004.8 as an orally active agent to alleviate scleroderma and, possibly, other fibrotic diseases as well.”
“The endocannabinoid (eCB) system plays a key role in many physiological and pathological conditions and its dysregulation has been described in several rheumatological and autoimmune diseases. Yet, its possible alteration in systemic lupus erythematosus (SLE) has never been investigated.
Here, we aimed filling this gap in plasma and peripheral blood mononuclear cells (PBMCs) of patients with SLE and age- and sex- matched healthy subjects (HS).
In conclusion, our results demonstrate, for the first time, an alteration of eCB system in SLE patients. They represents the first step toward the understanding of the role of eCB system in SLE that likely suggest DAGL and 2-AG as potential biomarkers of SLE in easily accessible blood samples.
Our data provides proof-of-concept to the development of
