Fig. 5From: Omega-3 polyunsaturated fatty acid supplementation attenuates microglial-induced inflammation by inhibiting the HMGB1/TLR4/NF-κB pathway following experimental traumatic brain injuryω-3 PUFA supplementation inhibits neuronal apoptosis in lesioned cortices. a ω-3 PUFA supplementation significantly decreased the rate of TUNEL-positive neurons after TBI (56.19 ± 6.60% vs. 83.23 ± 5.46%, p < 0.05). Arrows point to TUNEL-positive neurons. b The rate of neuronal apoptosis in the three groups; n = 6 in each group. The values are expressed as mean ± standard deviation: *p < 0.05, ** p < 0.01, scale bars = 50 μmBack to article page
