Cysteinyl leukotrienes (including LTC4 , LTD4 and LTE4) , potent inflammatory mediators, can induce brain - blood-barrier (BBB) disruption and brain edema. These reactions are mediated by their receptors, CysLT1 and CysLT2 receptors. On the other hand, aquaporin 4 ( AQP4) primarily modulates brain water homeostasis and edema after various injuries. Here, we aimed to determine whether AQP4 is involved in LTD4 -induced brain edema. LTD4 (1 ng in 0. 5μl PBS) mi-
