In a preterm hypoxia-ischemia model in the post-natal day 3 rat, we characterized how the expression of purine ionotropic P2X(4) receptors change in the brain post-insult. After hypoxia-ischemia, P2X(4) receptor expression increased significantly and was associated with a late increase in ionised calcium binding adapter molecule-1 protein expression indicative of microglia cell activation. Minocycline, a potent inhibitor of microglia, attenuated the hypoxia-ischemia-induced increase in P2X(4) receptor expression. We postulate that P2X(4) receptor-positive microglia may represent a population of secondary injury-induced activated microglia. Future studies will determine whether this population contributes to the progression of injury in the immature brain. (C) 2009 Elsevier B.V. All rights reserved.
