Therefore, our results suggest that the protective effects of MaR1 on sepsis could be related to the recovery of metabolic dysfunction and the alleviation of inflammation and mitochondrial damage.
RvD1, RvD2, maresin 1 (MaR1), and apoptotic neutrophils reduced miR-466l expression within human macrophages, a feedback regulation that most likely prepares for homeostasis. miR-466l was upregulated in peripheral blood of sepsis patients, and its increase correlated with nonsurvival from sepsis.
In the present study, we investigated the effects of maresin 1 (MaR1) on mitochondrial function in cecal ligation and puncture (CLP)-induced sepsis and sepsis patients to identify mechanisms underlying maresin 1-mediated stimulation of ROS in mitochondria.

MaR1 effects on fatty liver disease were tested in ob/ob (2-10 μg kg<sup>-1</sup> i.p., 20 days) and in diet-induced obese (DIO) mice (2 μg kg<sup>-1</sup>, i.p., or 50 μg kg<sup>-1</sup>, oral gavage for 10 days), as well as in cultured hepatocytes.
Chronic unresolved inflammation contributes to the development of nonalcoholic steatohepatitis (NASH), a disorder characterized by lipotoxicity, fibrosis, and progressive liver dysfunction.In this issue of the JCI, Han et al. report that maresin 1 (MaR1), a proresolving lipid mediator, mitigates NASH by reprograming macrophages to an antiinflammatory phenotype.
In the present work, it has been studied whether the administration of two different PUFAs (docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA)) and a DHA-derived specialized pro-resolving lipid mediator (MaR1) is able to reverse cognitive deficits in the senescence-accelerated mouse prone 8 (SAMP8) mouse model of sporadic AD.
Accumulating evidence suggests that maresin 1 (MaR1) exhibits protective and anti-inflammatory effects in some diseases, such as pneumonia and colitis; however, its role in acute hepatitis remains unclear.
These data suggest that treatment with MaR1 can counteract the dysfunctional inflamed WAT and could be useful to improve insulin sensitivity in murine models of obesity.-Martínez-Fernández, L., González-Muniesa, P., Laiglesia, L. M., Sáinz, N., Prieto-Hontoria, P. L., Escoté, X., Odriozola, L., Corrales, F. J., Arbones-Mainar, J. M., Martínez, J.
The specialized proresolving molecule and macrophage mediator in resolving inflammation, MaR-1, produced by human macrophages, has potent defining effects that limit polymorphonuclear neutrophil infiltration, enhance uptake of apoptotic PMNs, regulate inflammation resolution and tissue regeneration, and reduce pain.
As the function of MaR1 in neuropathic pain remains unclear, we investigated the effects of MaR1 on pain hypersensitivity and the underlying mechanism using a rat spinal nerve ligation (SNL) model of neuropathic pain.
Cytogenetic analysis in a patient with erythroleukaemia revealed a hypodiploid cellular clone with several acquired karyotypic aberrations including an isochromosome for the long arm of chromosome 21 : 45,XY,-5,-7,-18,-19,-21, + 17, + i (21q)(qter leads to cen leads to qter), + mar1, + mar2.
