IL1B and concussion: In Fig. 3A, we see that trauma significantly increases the IL1β expression level, while DHEA treatment prevented the increase (206.4 ± 10.7 pg/mg of protein for “mTBI + DHEA” group, 274.5 ± 11.3 pg/mg of protein for “mTBI” group and 225.1 ± 11.5 pg/mg of protein for “SHAM” group) (Fig. 3A).
