Ation of extracellular glutamate, whereas, as pointed out previously, neighboring Bergmann glia are poorly impacted by this neurotoxic transmitter; and (3) ultimately, inside the post-OGD phase, judging by electrophysiological criteria, Bergmann glial cells recover completely while Purkinje neurons show only either a partial, or no recovery at all. Can we conclude for these motives that Bergmann glial cells are a lot more resistant to ischemia than Purkinje neurons In this similar direction, may be the all round role of Bergmann glial cells detrimental or protective for neuronal function On one particular side, within the cerebellum glutamate release from Bergmann glia has been identified to be closely connected with intracellular acidifications through OGD, indicating that these cells could be implicated in neurotoxicityOther Possible Channels Implicated in OGD-Mediated Effects on Bergmann GliaIt is significant to mention that ion channels apart from these mentioned so far might be involved in the responses of Bergmann glia to OGD. These conductances includeFrontiers in Cellular Neuroscience | www.frontiersin.orgNovember 2017 | Volume 11 | ArticleHelleringer et al.Bergmann Glia Responses to Ischemia(Beppu et al., 2014). However, despite the fact that we could not unambiguously identify a role for Bergmann glia in producing the excitatory drive that kills Purkinje cells through OGD, right here we nonetheless discovered elements suggesting that Bergmann glia could participate for the uptake of K+ from the extracellular space, a function possibly guarding and supporting neurons. Within the future, it will be interesting to tackle this challenge in situations that selectively target glial cells. A pharmacological strategy using fluorocitrate, a gliotoxin that beneath some situations, selectively inhibit astrocyte metabolism (Hassel et al., 1992; Vance et al., 2015) may perhaps represent a beneficial tactic to perturb Bergmann glia membrane prospective and its K+ buffer capabilities. An alternative genetic strategy would consist in applying Kir4.1 knockout mice. Kir4.1 channels are glia-specific K+ conductances that happen to be fundamental to retain a hyperpolarized membrane possible in glial cells and therefore they support an effective extracellular K+ buffering (Chever et al., 2010). Consequently these mice could represent a good model to study Bergmann glia-Purkinje neurons interaction through OGD. However, the conditional knockout of Kir4.1 gene in astrocytes induces premature death in mice (Djukic et al., 2007) therefore limiting experiments on mature animals (as performed in this short article). Clearly, additional components are needed to provide a response for the essential query regarding the precise role of astrocytes throughout ischemia.
