Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

1.5K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Overview of Cell Death01:30

Overview of Cell Death

7.1K
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...

Necrosis01:16

Necrosis

4.3K
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...

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...

Autophagic Cell Death01:18

Autophagic Cell Death

3.4K
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...

Apoptosis01:30

Apoptosis

11.2K
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...

Area of Science:

  • Cardiovascular Biology
  • Cellular Biology
  • Molecular Medicine

Background:

  • Cardiac hypertrophy is an enlargement of cardiomyocytes, not an increase in number.
  • Pathological cardiac hypertrophy, triggered by adverse stimuli, impairs cardiac function and can progress to heart failure.
  • Regulated cell death (RCD) pathways, including apoptosis, pyroptosis, ferroptosis, necroptosis, and autophagy, play critical roles in this process.

Purpose of the Study:

  • To review the molecular mechanisms and signaling pathways of RCD in pathological cardiac hypertrophy.
  • To highlight findings related to the mechanism of action of RCD pathways in this condition.
  • To propose novel cellular-level therapeutic strategies for preventing or reversing pathological cardiac hypertrophy.

Main Methods:

  • Literature review of molecular mechanisms and signaling pathways.
  • Analysis of RCD pathways (apoptosis, pyroptosis, ferroptosis, necroptosis, autophagy).
  • Focus on findings related to the mechanism of action in pathological cardiac hypertrophy.

Main Results:

  • Detailed summary of molecular mechanisms underlying various RCD pathways.
  • Explanation of signaling cascades involved in RCD during cardiac hypertrophy.
  • Identification of specific RCD pathways contributing to pathological cardiac hypertrophy progression.

Conclusions:

  • RCD pathways are integral to the pathogenesis of pathological cardiac hypertrophy.
  • Understanding these pathways offers opportunities for targeted cellular therapies.
  • Therapeutic strategies aimed at modulating RCD could prevent or reverse cardiac hypertrophy and heart failure.
