Figure 4.
The effects of P2X7R agonist and antagonist on clasmatodendrosis in the stratum radiatum of the CA1 region 4 weeks after SE. SE induces lysosomal-associated membrane protein-1 (LAMP1) positive clasmatodendrosis in the CA1 region (A,B). BzATP effectively reduces the number of LAMP1 positive clasmatodendritic astrocytes (C). Both OxATP and A490003 aggravate LAMP1 positive clasmatodendrosis (D,E). Bar = 25 μm. (F) The fraction of LAMP1 positive astrocytes in the total number of astrocytes within the CA1 region (means ± s.d., n = 5, respectively). *p < 0.05 vs. non-SE animals (one-way ANOVA test).
