Abstract
A novel form of sustained retinal ischemic tolerance is described, wherein endogenous adaptive responses triggered by repeated hypoxia afford protection against injury many weeks after the preconditioning stimulus. HIF-1alpha-mediated, long-lasting increases in retinal HO-1 expression may contribute to the LTT phenotype. Further elucidation of the genetic and molecular basis of such adaptive plasticity could provide therapeutic targets for preventing and/or treating a variety of ischemic retinopathies.
