Accumulating evidence indicates that stem cells (SCs) possess immunomodulatory, anti-inflammatory, and prohealing properties. The mechanisms underlying these functions are being investigated with the final goal to set a solid background for the clinical use of SCs and/or their derivatives. Specialized proresolving lipid mediators (SPMs) are small lipids formed by the enzymatic metabolism of polyunsaturated fatty acids. They represent a leading class of molecules that actively and timely regulate the resolution of inflammation and promote tissue/organ repair. SC formation of these mediators as well as expression of their receptors has been recently reported, suggesting that SPMs may be involved in the immunomodulatory, proresolving functions of SCs. In the present review, we summarize the current knowledge on SPMs in SCs, focusing on biosynthetic pathways, receptors, and bioactions, with the intent to provide an integrated view of SPM impact on SC biology.

Enhanced inflammatory and immune responses have been observed in patients with major depressive disorder, pointing to anti-inflammatory substances as potential seeds for developing novel antidepressants. Omega-3 polyunsaturated fatty acid metabolites, such as resolvin D and E series, maresins, and protectins (collectively known as specialized pro-resolving mediators) demonstrate anti-inflammatory effects. This study examined the antidepressant-like effects of maresin-1 (MaR1) on lipopolysaccharide (LPS)-induced depression-like behaviors in mice.

Neuropathy is the most common complication of diabetes, leading to painful symptoms like hyperalgesia. Current treatments for diabetic painful neuropathy often prove inadequate, necessitating the exploration of new pharmacological approaches. Therefore, this study aimed to investigate the potential antinociceptive effect of aspirin-triggered lipoxin A4 (ATL), a specialized pro-resolving lipid mediator, when administered alone or in combination with cannabinoid agonists, to alleviate diabetic neuropathic pain.

(1) Background: Impeded resolution of inflammation contributes substantially to the pathogenesis of Alzheimer's disease (AD); consequently, resolving inflammation is pivotal to the amelioration of AD pathology. This can potentially be achieved by the treatment with specialized pro-resolving lipid mediators (SPMs), which should resolve neuroinflammation in brains. (2) Methods: Here, we report the histological effects of long-term treatment with an SPM, maresin-like 1 (MarL1), on AD pathogenesis in a transgenic 5xFAD mouse model.

Cardiovascular disease (CVD), the leading cause of death in the United States and globally, is a chronic inflammatory disease likely caused by an impaired ability to resolve inflammation. Pre-clinical studies have provided strong evidence of the activating role of specialized pro-resolving lipid mediators (SPMs) derived from the omega-3 fatty acids eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA) and docosahexaenoic acid (DHA) on the resolution of inflammation. However, there is a dearth of information on the role of SPMs on inflammation in humans.

Purpose Of Review: This review summarizes recent literature falling broadly under the topic of n-3 polyunsaturated fatty acids (PUFAs) in the oncology setting, highlighting emerging themes and emphasizing novel explorations.
Recent Findings: Meta-analyses continue to confirm safety and efficacy of n-3 PUFA supplementation on reducing inflammation and improving survival in people with cancer. Common themes in recent studies emphasize improving tumor-directed efficacy and reducing toxicities of common cancer therapies.
