Insights

Death-associated protein kinase (DAPK) regulates neuronal cell death in both development and disease. Inhibiting DAPK protects neurons from injury, highlighting its critical role in neuronal survival.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Cell Death Research

Background:

  • Neuronal cell death is a fundamental process in both normal development and disease states.
  • Death-associated protein kinase (DAPK) is an intracellular serine/threonine kinase involved in mediating apoptotic cell death signals.
  • DAPK levels are increased in injured neurons following acute insults like ischemia and seizure.

Purpose of the Study:

  • To review the role of DAPK in neuronal cell death following injury.
  • To explain the involvement of DAPK in developmental neuronal cell death.

Main Methods:

  • Review of existing literature on DAPK and neuronal cell death.
  • Analysis of studies investigating DAPK's role in acute neuronal injury models (ischemia, seizure).
  • Examination of DAPK's function in programmed cell death during central nervous system development.

Main Results:

  • DAPK mediates neuronal cell death through its kinase activity and signal transmission.
  • Absence of DAPK confers protection to neurons against various acute toxic insults.
  • DAPK regulates the significant neuronal cell death occurring during central nervous system development.

Conclusions:

  • DAPK plays a crucial role in mediating neuronal cell death after injury.
  • DAPK is also a key regulator of programmed neuronal cell death essential for nervous system development.
  • Targeting DAPK may offer therapeutic strategies for protecting neurons in injury and disease.

Overview of Cell Death01:30

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Autophagic Cell Death01:18

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Cellular Injury V: Apoptosis and Autophagy

Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...

Cellular Injury IlI: Cellular Death01:11

Cellular Injury IlI: Cellular Death

Cell death is the irreversible loss of cellular structure and function, representing the final stage of severe injury. It plays a key role in both normal physiology and disease.Types of Cell DeathThe two main types are necrosis and apoptosis, though others like necroptosis and pyroptosis also exist.Necrosis:Necrosis is an unregulated form of cell death caused by severe injury such as trauma, toxins, or ischemia. It is characterized by cell swelling, membrane loss, rupture, and leakage of...
