IL4 and brain inflammatory disease: Results confirmed that a 6 h DFP exposure induced massive expression of il1β (fc: 189 ± 37, p < 0.01) and il8 (fc: 42 ± 19, p < 0.05), and increased expression of il4 transcripts (fc: 2.9 ± 0.7, p < 0.05) in the brain of exposed larvae (Figure 4), confirming that DFP exposure induced bona fide brain inflammation.
