Macrophage infiltration and M1 polarization induce WAT dysfunction. Krill oil (KO) possesses anti\u2010inflammation activity, but its effect on WAT dysfunction under T2DM remained unclear. To this end, T2DM was established in mice followed by a 6\u2010month KO supplementation, showing that KO significantly lowered fasting blood glucose level, mitigated insulin resistance, and improved WAT dysfunction. Notably, KO decreased the number of infiltrated M1\u2010polarized macrophages in the WAT. Moreover, lipolysis and insulin signaling impairment of the WAT were inhibited by KO. In vitro, KO blunted lipopolysaccharide\u2010induced macrophage M1 polarization. Furthermore, in co\u2010culture experiments, these KO\u2010treated macrophages resulted in a less expression of inflammatory factors and resistin, an elevation of adiponection level, as well as an enhanced lipid storage capacity in adipocytes. In summary, the current study found that KO might improve adipocyte dysfunction and insulin resistance by inhibiting macrophage M1 polarization, providing a potential approach for T2DM intervention.<\/jats:p>","DOI":"10.1002\/mnfr.70215","type":"journal-article","created":{"date-parts":[[2025,11,10]],"date-time":"2025-11-10T09:34:56Z","timestamp":1762767296000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Krill
