Insights

Apoptosis, programmed cell death, occurs in heart muscle cells after myocardial infarction. Understanding and blocking this process may offer new treatments for reperfusion injury.

Area of Science:

  • Cardiovascular Biology
  • Cellular Biology
  • Pathophysiology

Context:

  • Myocardial infarction (MI) involves tissue damage and subsequent reperfusion.
  • Apoptosis, or programmed cell death, is observed in cardiomyocytes within the reperfusion zone post-MI.
  • Growth factors and hormones can influence apoptosis in homeostatic tissues.

Purpose:

  • To investigate the role of cardiomyocyte apoptosis in myocardial infarction and reperfusion injury.
  • To explore the unresolved molecular and cellular mechanisms underlying this apoptotic process.
  • To discuss potential therapeutic strategies targeting cardiomyocyte apoptosis for myocardial protection.

Summary:

  • Apoptosis is initiated in cardiac muscle cells in the reperfusion zone during early myocardial infarction.
  • While cardiomyocyte apoptosis is crucial in reperfusion syndrome progression, its mechanisms remain unclear.
  • Blocking cardiomyocyte apoptosis presents a novel preventive treatment approach for myocardial ischemia-reperfusion injury.

Impact:

  • Provides insights into the cellular mechanisms of myocardial infarction and reperfusion injury.
  • Highlights the significance of cardiomyocyte apoptosis in cardiac damage.
  • Suggests a promising avenue for developing novel therapeutic interventions to protect the myocardium.

Apoptosis

Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
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...
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 anucleated and die, but their...

Myocarditis I: Introduction

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Cellular Injury IV: Necrosis

Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...

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...
