Summary: The study demonstrated that carboxylesterases PLE1 and PLE6 can hydrolyze endocannabinoids 2-AG and AEA, leading to increased inflammatory response. Exogenous addition or transfection of PLE6 enhanced the expression and secretion of proinflammatory cytokines, while BNPP reduced inflammation triggered by LPS and inhibited the formation of AA and proinflammatory mediators. This innovative connection between PLE-endocannabinoid-inflammation highlights the critical roles of carboxylesterases in pathophysiological processes related to endocannabinoid metabolism.

Summary: Arachidonic acid (AA) metabolism plays a critical role in the initiation and resolution of inflammation. Prostaglandin E2 (PGE2) and lipoxin A4 (LXA4) interact in a regulatory manner during inflammation, aiding in inflammation resolution and tissue regeneration.

Summary: The available literature synthesis suggests an association between the arachidonic acid (AA) pathway and male fertility based on in vivo animal studies and human clinical trials. PGE is significantly reduced in the semen of infertile men, indicating the potential of PGE agonists to improve male fertility. Interestingly, ibuprofen can negatively affect male fertility by inducing alterations in sperm function and standard semen parameters. Targeting the AA pathways could be an attractive strategy for the treatment of male fertility.

Summary: Eicosanoids are a family of lipid signaling mediators derived from arachidonic acid (AA) and play a role in physiological and pathological processes in the brain. Their synthesis is primarily catalyzed by cyclooxygenases (COX) and lipoxygenases (LOXs). The metabolites of AA have dual properties of pro-inflammatory and anti-inflammatory effects, potentially contributing to chronic neuroinflammation. Targeting Eicosanoid-related pathways may offer therapeutic benefits for depression.

Summary: In this study, it was found that there is crosstalk between EETs and prostaglandins in the vascular system, and the lack of EET production sensitizes vessels to vasoconstriction. These findings have important implications for understanding vascular function and the development of related diseases.

Summary: Arachidonic acid is a polyunsaturated fatty acid that plays roles in inflammation, pain, and immune function. Its metabolism through various pathways produces eicosanoids, which are associated with inflammatory, renal, cardiovascular diseases, and diabetes. Targeting the metabolism of arachidonic acid may provide new therapies for diabetes.

Summary: The present article describes the design, synthesis, characterization, docking studies, and anti-inflammatory activity of two new series of lonazolac analogues. The synthesized compounds exhibited excellent COX-1 and COX-2 inhibitory activity and superior selectivity. Compound 2n showed excellent COX-1 inhibitory activity, while compound 2g was an excellent COX-2 inhibitor. Compound 2l showed excellent anti-inflammatory activity against MMP-2 and MMP-9. The molecular docking study indicated that the synthesized compounds had better anti-inflammatory activity than the standard drugs.

Summary: In this study, it was shown that CD4(+) T cells from patients with RA and PsA have increased expression of the pore-forming calcium channel component ORAI3 due to reduced IKAROS expression, leading to increased ARC channel activity and sensitivity to arachidonic acid. This heightened activity may contribute to chronic inflammation in these conditions, indicating a potential mechanism for the pathogenesis of RA and PsA.

Summary: An accurate prediction model based on arachidonic acid metabolites was developed to predict mortality in patients with acute decompensated heart failure. The model showed high accuracy in predicting death in validation cohort and provided incremental information beyond existing clinical scores. In a murine model, inhibiting soluble epoxide hydrolase was shown to be a potential therapeutic target for treating heart failure.

Summary: Cancer, a major global disease burden, is influenced by inflammation. Eicosanoids, derived from dietary fatty acids like arachidonic acid (AA), are involved in inflammation-related cancers. This research summarizes dietary sources of AA, eicosanoid biosynthesis, their bioactivities, potential molecular mechanisms, and current challenges in studying eicosanoids in relation to inflammation-related cancer.

Summary: CPB/DHCA leads to a significant increase in pulmonary tissue AA and its metabolites, with elevated levels of prostaglandins in the lower lobes of control animals. This suggests a separate mechanism from CPB/DCHCA, highlighting the need for further studies on oxylipins to better understand CPB-induced lung injury.

Summary: This study explores the important role of eosinophils in allergic inflammation through the production of lipid mediators, as well as their regulatory function in local immunity and repair. Targeting the complex network of lipid mediators offers a unique opportunity to modulate eosinophil activity without compromising other leukocytes and tissue-resident eosinophils.

Summary: This study aimed to evaluate the protective role of nanocurcumin as an antioxidant and anti-inflammatory agent, and its synergistic effects with Donepezil in the treatment of Alzheimer's disease in rats. The results showed that treatment with nanocurcumin improved memory, locomotion, and neuronal differentiation by activating the PI3K/AKT/GSK-3 beta pathway.
