Palmitoylethanolamide causes dose-dependent changes in brain function and the lipidome.

The present studies were undertaken to understand the effects of the commonly used nutraceutical PEA on brain function and lipid chemistry. These studies using MRI and broad-scale lipidomics are without precedent in animal or human research. During the MRI scanning session awake rats were given one of three doses of PEA (3, 10, or 30 mg/kg) or vehicle and imaged for changes in BOLD signal and functional connectivity.

Visual exposure to green light therapy reduces knee joint pain and alters the lipidome in osteoarthritic rats.

Visual exposure to dim, green, light has been found to reduce pain levels in patients living with migraine, low back pain, and fibromyalgia. Preclinical studies discovered that the analgesic effect of green light was due to the central release of endogenous opioids and a reduction in inflammatory cytokines in the cerebrospinal fluid. The present study assessed the effect of green light therapy (GLT) on joint pain in a rat model of osteoarthritis (OA) and investigated the role of endolipids.

Endocannabinoid regulation in the cervix during pregnancy: insights into molecular mechanisms of premature labor.

In Brief: The cervix plays a crucial role not only in the maintenance of pregnancy but also during delivery, when it undergoes extensive changes. This study highlights the involvement of the endocannabinoidome in cervical remodeling, emphasizing its relevance in the shift from a nonpregnant to pregnant state and its potential contribution to preterm delivery in inflammatory contexts.

Abstract: During pregnancy, the main role of the cervix is to isolate the fetus from outside pathogens and maintain the relatively closed system of uterine gestation.

Discovery and Preclinical Evaluation of a Novel Inhibitor of FABP5, ART26.12, Effective in Oxaliplatin-Induced Peripheral Neuropathy.

Oxaliplatin-induced peripheral neuropathy (OIPN) is a dose-limiting toxicity characterised by mechanical allodynia and thermal hyperalgesia, without any licensed medications. ART26.12 is a fatty acid-binding protein (FABP) 5 inhibitor with antinociceptive properties, characterised here for the prevention and treatment of OIPN.
