“Alzheimer’s disease (AD) is characterized by progressive cognitive decline and pathologically by the accumulation of amyloid-β (Aβ) and tau hyperphosphorylation causing neurodegeneration and neuroinflammation. Current AD treatments do not stop or reverse the disease progression, highlighting the need for more effective therapeutics.
The phytocannabinoid cannabidiol (CBD) has demonstrated antioxidant, anti-inflammatory, and neuroprotective properties. Furthermore, chronic CBD treatment (20 mg/kg) reverses social and object recognition memory deficits in the AβPPxPS1 transgenic mouse model with only limited effects on AD-relevant brain pathology.
Importantly, studies have indicated that CBD works in a dose-dependent manner. Thus, this study determined the chronic effects of 50 mg/kg CBD in male AβPPxPS1 mice. 12-month-old mice were treated with 50 mg/kg CBD or vehicle via daily intraperitoneal injections for 3 weeks prior to behavioral testing. A variety of cognitive domains including object and social recognition, spatial and fear-associated memory were evaluated. Pathological brain analyses for AD-relevant markers were conducted using ELISA and western blot.
Vehicle-treated male AβPPxPS1 mice demonstrated impaired social recognition memory and reversal spatial learning. These deficits were restored after CBD treatment. Chronic CBD tended to reduce insoluble Aβ40 levels in the hippocampus of AβPPxPS1 mice but had no effect on neuroinflammation, neurodegeneration, or PPARγ markers in the cortex.
This study demonstrates that therapeutic-like effects of 50 mg/kg CBD on social recognition memory and spatial learning deficits in AβPPxPS1 mice are accompanied by moderate brain region-specific reductions in insoluble Aβ40 levels. The findings emphasize the clinical relevance of CBD treatment in AD; however, the underlying mechanisms involved require further investigation.”

“Inflammatory Bowel Disease (IBD) is idiopathic, chronic and affects the gastrointestinal tract. It results from the association of genetic, environmental and immune deregulation, which culminates in the development and progression of the inflammatory process. In an attempt to reverse colonic inflammation, endogenous systems involved in intestinal physiology are studied and the cholinergic system is fundamental for this process. In addition, this system has anti-inflammatory action in experimental models of IBD. Another important endogenous system in regulating the exacerbated inflammatory response in the gut is mediated by endocannabinoids, which play an important role in restoring bowel functionality after the onset of the inflammatory process. There are several reports in the literature showing the interconnection between the cannabinoid and cholinergic systems in different tissues. Considering that the activation of the cholinergic system stimulates the production of cannabinoid agonists in the intestine, our hypothesis is that the interaction between the muscarinic system and the cannabinoid in the control of intestinal inflammation is mediated by endogenous cannabinoids, since they are stimulated by the activation of muscarinic receptors.”
“In the process of neonatal encephalopathy, oxidative stress and neuroinflammation have a prominent role after perinatal asphyxia. With the exception of therapeutic hypothermia, no therapeutic interventions are available in the clinical setting to target either the oxidative stress or inflammation, despite the high prevalence of neurological sequelae of this devastating condition.
