Programmed cell death, or apoptosis, is vital for tissue balance. This review explores how caspase enzymes, key proteins in apoptosis, are activated through various molecular pathways.

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Biochemistry

Background:

  • Apoptosis, or programmed cell death, is a fundamental biological process crucial for maintaining tissue homeostasis.
  • The intricate molecular signaling pathways governing apoptosis involve numerous protein players.
  • Caspase enzymes, a distinct class of cysteine proteases, are central effectors of the cell death machinery.

Purpose of the Study:

  • To review the current understanding of apoptosis.
  • To elucidate the diverse pathways involved in the activation of caspases.
  • To highlight key proteins that regulate these caspase-activating pathways.

Main Methods:

  • Literature review of scientific publications on apoptosis and caspase activation.
  • Synthesis of information regarding molecular signaling cascades in programmed cell death.
