Anti-inflammatory and anti-apoptotic activity of synaptamide improves the morphological state of neurons in traumatic brain injury.

Traumatic brain injuries (TBI) of varying severity are becoming more frequent all over the world. The process of neuroinflammation, in which macrophages and microglia are key players, underlies all types of brain damage. The present study focuses on evaluating the therapeutic potential of N-docosahexaenoylethanolamine (DHEA, synaptamide), which is an endogenous metabolite of docosahexaenoic acid in traumatic brain injury.

Anti-inflammatory Effect of Polyunsaturated Fatty Acid N-Acylethanolamines Mediated by Macrophage Activity In Vitro and In Vivo.

In recent years, there has been increasing interest in studying the anti-inflammatory activity of polyunsaturated fatty acid ethanolamides (N-acylethanolamines, NAE), which are highly active lipid mediators. The results of this study demonstrate that a dietary supplement (DS) of fatty acid-derived NAEs reduces LPS-induced inflammation. The processes of cell proliferation, as well as the dynamics of Iba-1-, CD68-, and CD163-positive macrophage activity within the thymus and spleen were studied.

Fatty Acid-Derived -acylethanolamines Dietary Supplementation Attenuates Neuroinflammation and Cognitive Impairment in LPS Murine Model.

Neuroinflammation plays a critical role in the pathogenesis of most neurological and neurodegenerative diseases and therefore represents a potential therapeutic target. In this regard, accelerating the resolution process in chronic neuroinflammation may be an effective strategy to deal with the cognitive consequences of neuropathology and generalized inflammatory processes. -acylethanolamine (NAE) derivatives of fatty acids, being highly active lipid mediators, possess pro-resolving activity in inflammatory processes and are promising agents for the suppression of neuroinflammation and its consequences.

Chimyl Alcohol Exhibits Proinflammatory Activity in vivo and in vitro.

Marine organisms are among the prominent and abundant sources of 1-O-alkyl-sn-glycerols, including chimyl alcohol (CA), batyl alcohol and selachyl alcohol. These biologically active compounds are precursors in plasmalogen and phospholipid biosynthesis, which are the main irreplaceable components of cell membranes. The results of this study demonstrate that CA promotes the activation of immune processes in the mouse spleen and in the mouse macrophage cell culture RAW 264.
