a–e Suppression of TBI-induced acute inflammatory cytokine expression in mice with higher brain docosahexaenoic acid. TBI induced the gene expression of pro-inflammatory cytokines in the cerebral cortex. Adequate α-linolenic acid (ALA) diet resulted in lower expression of pro-inflammatory cytokines TNF-α, IL-1β, IL-6, and CCL2 after TBI as compared to the low ALA group. n = 3–4. ***p < 0.001, **p < 0.01 compared to the low ALA diet group for the respective time point. Data are expressed as mean ± SD
