Differences in the cellular metabolic status and mitochondrial activity of splenic NK cells between DHA-fed and control mice at day 7 post-MCMV infection. A–E Flow cytometric analysis and cumulative results depicting the gMFI of CD71 (A) and CD98 (B) and the uptake of 2-NBDG (C), MitoTracker (D) and tetramethylrhodamine, methyl ester (TMRM) (E) by splenic NK cells (CD3⁻CD19⁻NK1.1⁺NKp46⁺) from control versus DHA-fed mice at day 7 postinfection. For each experiment, n = 7 pooled from 2 independent experiments. Each symbol represents an individual mouse, and the blue dots and red squares represent control and DHA-enriched diet-fed mice, respectively. Error bars represent interquartile ranges; *p < 0.05; **p < 0.01; ***p < 0.001
