Abstract in brief

  • The study demonstrates that the cellular prion protein (PrP) in astrocytes plays a key role in initiating apoptosis by activating Caspase 3, which is important for cell death and maintaining healthy cell growth.
  • PrP is involved in regulating metal balance within cells, specifically by lowering intracellular calcium levels, which influences cell survival and growth rates.
  • Cells lacking PrP (knockout cells) show faster growth and reduced apoptosis, highlighting PrP’s essential function in controlling cell death pathways and overall cell health in the brain.]
