P2RY1 and cerebral cortical dysplasia: Although P2Y1 has been described to be expressed on astrocytes under different pathological conditions, such as oxidative stress (Shinozaki et al., 2006; Fujita et al., 2009), ischemia (Zheng et al., 2013), and in patients with cortical dysplasia (Sukigara et al., 2014), no expression of P2Y1 was detected on astrocytes in the cortex in our status epilepticus mouse model.
