Sejnowski and Pinto-Duarte showed that although the mice without IP3R2 and reduced astrocyte activity had no problems with the former, they exhibited significant deficits in the latter, suggesting that astrocytes may be playing a role specifically in the long-term depression of the connections between neurons.
Rothstein's team focused on a particular astrocyte protein, glutamate transporter-1, which previous studies suggested was lost from astrocytes in certain parts of brains with neurodegenerative diseases.
They observed that the level of expression of this gene declines naturally, a short time before astrocyte production begins.
On day 7, inserts were selected at random and moved to a new plate, with paraformaldehyde/PBS added to the astrocyte and endothelial sides of the insert and fixed.
To measure the pH balance within endosomes without breaking open the astrocyte, researchers used pH-sensitive probes that are absorbed by endosomes and emit light based on pH levels.
Mouse cortical astrocytes C8-D1A (astrocyte type I clone from C57/BL6 strains), were purchased from the American Type Culture Collection (ATCC, CRL-2541[TM], USA).
