Abstract

Purinergic neurotransmission in the cerebellum has been widely studied by our research group, being identified several signaling pathways activated by nucleotide receptors in cerebellar granule neurons and astrocytes (Espada et al., 2010; Carrasquero et al., 2009; Ortega et al., 2010; Ortega et al., 2011). In granule neurons, P2X7 ionotropic receptor and P2Y13 metabotropic receptor exert neuroprotective effects against several proapoptotic stimuli, activating different signalling pathways. These include the survival pathway leading to GSK3 (Glycogen synthase kinase 3) inhibition, either through the PI3K/Akt (Phosphoinositide 3-kinase/ Protein kinase B) canonical pathway for P2Y13 receptor, or through a protein kinase C-dependent pathway for the P2X7 receptor. In addition, both receptors activate the MAP Kinases, ERK1,2 (Extracellular signal–regulated kinases), through CaMKII (Calcium calmodulin kinase II) and PI3K/Akt for P2X7 and P2Y13 receptors, respectively (Ortega et al., 2008; Ortega et al., 2009; Ortega et al., 2011)...
