Angiotensin II receptor type 2 (AT2) agonists have been shown to limit brain ischemic insult and to improve its outcome. The activation of AT2 was also linked to induced neuronal proliferation and differentiation in vitro. In this study, we examined the therapeutic potential of AT2 activation following traumatic brain injury (TBI) in mice, a brain pathology(More)
Preconditioning via heat acclimation (34°C 30 d) results in neuroprotection from traumatic brain injury due to constitutive as well as dynamic changes triggered by the trauma. Among these changes is Akt phosphorylation, which decreases apoptosis and induces HIF1α. In the present study we investigated the Akt downstream GSK3β/β-catenin pathway and focused on(More)
Long-term exposure of mice to mild heat (34°C±1°C) confers neuroprotection against traumatic brain injury (TBI); however, the underling mechanisms are not fully understood. Heat acclimation (HA) increases hypothalamic angiotensin II receptor type 2 (AT2) expression and hypothalamic neurogenesis. Accumulating data suggest that activation of the brain AT2(More)
Heat acclimation (HA), a well-established preconditioning model, confers neuroprotection in rodent models of traumatic brain injury (TBI). It increases neuroprotective factors, among them is hypoxia-inducible factor 1α (HIF-1α), which is important in the response to postinjury ischemia. However, little is known about the role of HIF-1α in TBI and its(More)
Neuroprotection following prolonged exposure to high ambient temperatures (heat acclimation HA) develops via altered molecular programs such as cross-tolerance Heat Acclimation-Neuroprotection Cross-Tolerance (HANCT). The mechanisms underlying cross-tolerance depend on enhanced "on-demand" protective pathways evolving during acclimation. The protection(More)
