“Osteoarthritis (OA) is the most common disease of joints, which are complex organs where cartilage, bone and synovium cooperate to allow the range of movements. During the disease progression, the function of all three main components is jeopardized. Nevertheless, the involvement of each tissue in OA development is still not established and is the topic of the present review. The available OA therapies are symptomatic, largely targeting pain management rather than disease progression. The strong need to develop a treatment for cartilage degeneration, bone deformation and synovial inflammation has led to research on the involvement of the endocannabinoid system in the development of OA. The current review discusses the research on this topic to date and notes the advantages of exploiting endocannabinoid system modulation for cartilage, bone and synovium homeostasis, which could prevent the further progression of OA.” https://www.ncbi.nlm.nih.gov/pubmed/29574720 https://bpspubs.onlinelibrary.wiley.com/doi/abs/10.1111/bph.14204
Joint problems arising from lack of repair mechanisms: can cannabinoids help?
“We provide experimental evidence to show that activation of the cannabinoid system enhances the survival, migration and chondrogenic differentiation of MSCs, which are three major tenets behind the success of a cell-based tissue-engineered cartilage repair strategy. These findings highlight the potential for cannabinoids to provide a dual function by acting as anti-inflammatory agents as well as regulators of MSC biology in order to enhance tissue engineering strategies aimed at cartilage repair.”

Although the underlying biological mechanisms of ASD remain poorly understood, recent preclinical research has implicated the endogenous

“Endocannabinoids are involved in depressive and anxious symptoms and might play a role in stress-associated psychiatric disorders.
While alterations in the endogenous cannabinoid system have been repeatedly found in patients with posttraumatic stress disorder (PTSD), this system has been mostly neglected in borderline personality disorder (BPD). However, there is first evidence for elevated serum levels of the endocannabinoids arachidonylethanolamide (AEA) and 2-arachidonyl-sn-glycerol (2-AG) in BPD patients compared to healthy controls and PTSD patients.
In this study, hair endocannabinoids were analyzed, reflecting long-term endocannabinoid concentrations. We assessed AEA concentrations as well as 2-AG and the 2-AG main isomer 1-AG (1-AG/2-AG) in hair in women with BPD (n = 15) and age- and education-matched healthy women (n = 16).
We found significantly reduced log AEA in BPD patients compared to healthy women (p = .03) but no differences in log 1-AG/2-AG concentrations. In addition, there was no association between 1-AG/2-AG and hair cortisol, but we found a non-significant correlation between hair concentrations of AEA and cortisol (p = .06).
Our data indicate altered long-term release of endogenous cannabinoids in women with BPD depending on type of endocannabinoid. AEA has been suggested to modulate the basal activity of the endocannabinoid system and seems to attenuate depressive and anxious symptoms. Thus, chronically reduced AEA might contribute to psychiatric symptoms in BPD.”
“The current serotonin-based biological model of suicidal behavior (SB) may be too simplistic. There is emerging evidence that other biomarkers and biological systems may be involved in SB pathophysiology. The literature on the endocannabinoid (EC) systems and SB is limited. The objective of the present article is to review all available information on the relationship between cannabinoid receptors (CB1 and CB2 receptors), and SB and/or psychological pain.
