Insights

Extracellular signal-regulated kinase (ERK) promotes neuronal death, distinct from apoptosis, in neurodegenerative diseases. This review explores the mechanisms behind ERK-mediated neuronal degeneration and its molecular players.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Cell Signaling

Background:

  • Extracellular signal-regulated kinase (ERK) is a key signaling protein involved in diverse biological processes.
  • ERK has been linked to neuronal degeneration, particularly in the context of neurodegenerative diseases.
  • Understanding the mechanisms of ERK-induced neuronal death is crucial for developing therapeutic strategies.

Purpose of the Study:

  • To review the evidence implicating ERK as a primary driver of non-apoptotic neuronal death.
  • To discuss the molecular mechanisms underlying ERK-mediated neuronal degeneration.
  • To identify potential molecular targets involved in this process.

Main Methods:

  • Literature review of studies investigating ERK signaling in neuronal degeneration.
  • Analysis of experimental data linking ERK activation to specific cell death pathways.
  • Discussion of proposed molecular interactors in ERK-mediated neuronal death.

Main Results:

  • ERK signaling predominantly induces a non-apoptotic form of neuronal death.
  • Specific signaling cascades and molecular players mediating ERK-induced neuronal death are being elucidated.
  • ERK's role extends beyond normal development to pathological conditions like neurodegeneration.

Conclusions:

  • ERK is a significant inducer of non-apoptotic neuronal death.
  • Further research into ERK pathways may reveal novel therapeutic targets for neurodegenerative diseases.
  • Elucidating the molecular mechanisms of ERK-mediated neuronal death is essential for understanding neuronal fate.

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...
MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

Amplifying Signals via Enzymatic Cascade

When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
Enzyme-linked Receptors01:00

Enzyme-linked Receptors

Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...
PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
