Calcium responses occurred in both astrocyte processes and endfeet that rapidly followed neuronal events ( approximately 120 ms after). These fast astrocyte responses were largely independent of IP3R2-mediated signaling.

Astrocytes are a key component of cerebral NVC, but their role in spinal NVC is unclear. The objective of this study was to examine whether inhibition of astrocyte …
Web3 mrt. 2024 · Reactive astrocytes establish immune responses through morphological changes and proliferation. The process achieved is through extension and hypertrophy, distinct from the microglial contraction process. Astrocytes are divided into A1 neurotoxic phenotype and A2 neuroprotective phenotype ( Escartin et al., 2024 ).
