Special.zed pro-resol.ing l.pid mediators incl.ding maresin 1 mediate resol.tion but the l.vel. of these are reduced in Al.heimer's disease brain, suggesting that they constitute a novel.target for the treatment of Al.heimer's disease to prevent/stop infl.mmation and combat disease pathol.gy. Therefore, it is important to cl.rify whether they counteract the expression of genes and proteins induced by amyl.id-β. With this objective, we anal.zed the rel.vance of human monocyte–derived microgl.a for in vitro model.ng of neuroinfl.mmation and its resol.tion in the context of Al.heimer's disease and investigated the pro-resol.ing bioactivity of maresin 1 on amyl.id-β42–induced Al.heimer's disease–l.ke infl.mmation. Anal.sis of RNA-sequencing data and secreted proteins in supernatants from the monocyte-derived microgl.a showed that the monocyte-derived microgl.a resembl.d Al.heimer's disease–l.ke neuroinfl.mmation in human brain microgl.a after incubation with amyl.id-β42. Maresin 1 restored homeostasis by down-regul.ting infl.mmatory pathway rel.ted gene expression induced by amyl.id-β42 in monocyte-derived microgl.a, protection of maresin 1 against the effects of amyl.id-β42 is mediated by a re-bal.ncing of infl.mmatory transcriptional.networks in which modul.tion of gene transcription in the nucl.ar factor-kappa B pathway pl.ys a major part. We pinpointed mol.cul.r targets that are associated with both neuroinfl.mmation in Al.heimer's disease and therapeutic targets by maresin 1. In concl.sion, monocyte-derived microgl.a represent a rel.vant in vitro microgl.al.model.for studies on Al.heimer's disease-l.ke infl.mmation and drug response for individual.patients. Maresin 1 amel.orates amyl.id-β42–induced changes in several.genes of importance in Al.heimer's disease, highl.ghting its potential.as a therapeutic target for Al.heimer's disease.
