The molecular mosaic of regulated cell death in the cardiovascular system

Area of Science:

• Molecular Biology
• Cardiovascular Science
• Pathology

Background:

• Cell death is a regulated process vital for development and tissue homeostasis.
• Dysregulated cell death contributes to numerous pathological conditions.
• At least 7 distinct cell death pathways are recognized, including apoptosis, necroptosis, and ferroptosis.

Purpose of the Study:

• To review the diverse molecular mechanisms of cardiomyocyte cell death.
• To elucidate how different cell death pathways contribute to cardiac pathologies.
• To highlight the therapeutic potential of understanding these processes.

Main Methods:

• Comprehensive literature review of molecular mechanisms of cell death.
• Analysis of the interplay between different cell death pathways in the heart.
• Synthesis of information on the role of cell death in cardiac disease.

Main Results:

• Detailed description of 7 distinct cell death processes: apoptosis, mitochondrial permeability transition (MPT)-driven necrosis, necroptosis, ferroptosis, pyroptosis, parthanatos, and autophagy-mediated cell death.
• Explanation of how these processes collectively influence cardiomyocyte fate.
• Identification of specific pathways implicated in various cardiac pathologies.

Conclusions:

• Cardiomyocyte cell death is a complex, context-dependent process involving multiple pathways.
• Understanding the molecular details of these pathways is crucial for developing targeted therapies.
• Targeting specific cell death mechanisms offers a promising strategy to prevent cardiomyocyte loss and improve patient outcomes.
