Article Synopsis
  • Reactive astrogliosis is a response of astrocytes to CNS injuries like intracerebral hemorrhage, characterized by abnormal cell growth and shape.
  • Thrombin, released when the blood-brain barrier is compromised, triggers reactive astrogliosis by increasing TRPC3 protein levels in astrocytes, leading to heightened Ca(2+) influx and signaling pathways.
  • Inhibition of TRPC3 or Ca(2+) blockers can prevent astrocytic changes and proliferation induced by thrombin, suggesting TRPC3 plays a crucial role in astrocyte activation during brain injury.

Activated astrocytes show various patterns of Ca(2+) mobilization under pathological conditions. In the present study we revealed a novel function of astrocytic Ca(2+) dynamics through investigation of thrombin-induced unique Ca(2+) entry. Using 1321N1 human astrocytoma cells, which have been shown to be a good model for detecting morphological dynamics, we observed rapid retraction of bipolar protrusions that were reversibly evoked by 0.
