Abstract

The search for novel neuroprotection strategies in ischemic stroke continues, as revascularization using tissue-plasminogen activator is the only pharmacological method currently available to patients. The purpose of this review article is to summarize research findings regarding the erythropoietin-producing hepatocellular receptor pathway as an emerging novel molecular target for neuroprotection in ischemic stroke. Ephrin–Eph interactions represent a new strategy in neuroprotection. Potential therapeutic targets include the different cellular locations within the neurovascular unit (e.g. astrocytes and neurons) and the different ephrin receptor subtypes. In particular, ephrin-B2/EphB4 receptor stimulation seems to exert neuroprotective effects, while stimulation of other ligands/receptors results in deleterious effects, during the post-ischemic stroke recovery phase. Neuroprotection, assessed by either a decrease in neurovascular unit injury markers or improvement in motor function tests, can be achieved by modulating the activity of different ephrin–Eph receptor subtypes. These novel molecular targets provide multiple potential neuroprotective therapeutic benefits, with meaningful clinical outcomes.
