Insights

Necroptosis, a cell death pathway, is implicated in cardiovascular diseases via the RIPK3-CaMKII-mPTP signaling pathway. This pathway

Area of Science:

  • Molecular Biology
  • Cardiovascular Research
  • Cell Death Mechanisms

Background:

  • Necroptosis is a regulated form of cell death crucial for homeostasis and implicated in cardiovascular disease pathogenesis.
  • Key necroptosis mediators include Receptor Interacting Protein Kinase (RIPK) 1, RIPK3, and mixed lineage kinase domain-like protein.

Approach:

  • This review synthesizes current research on the RIPK3-CaMKII-mPTP signaling pathway in cardiovascular diseases.
  • It focuses on the role of this pathway in conditions like myocardial infarction, heart failure, and atherosclerosis.

Key Points:

  • Calcium/calmodulin-dependent protein kinase II (CaMKII) is a RIPK3 substrate that triggers mitochondrial permeability transition pore (mPTP) opening.
  • This RIPK3-CaMKII-mPTP axis mediates necroptosis in myocardial cells.
  • The pathway's involvement is explored across diverse cardiovascular pathologies and drug toxicities.

Conclusions:

  • The RIPK3-CaMKII-mPTP signaling pathway is a significant contributor to cardiovascular diseases.
  • Understanding this pathway offers potential therapeutic targets for treating various heart conditions and drug-induced cardiotoxicity.

Necrosis01:16

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

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...

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...

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...

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

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...
