Insights

Mitophagy, the cellular process of degrading damaged mitochondria, is crucial for homeostasis. Its roles in pathogenic fungi, impacting growth and virulence, differ significantly from its functions in mammals and yeast.

Area of Science:

  • Molecular Biology
  • Cellular Biology
  • Mycology

Background:

  • Mitophagy is essential for mitochondrial quality control and cellular homeostasis in eukaryotes.
  • While well-studied in mammals and yeast (Saccharomyces cerevisiae), its role in pathogenic filamentous fungi remains underexplored.
  • Recent research highlights distinct functions of mitophagy in fungal pathogenesis.

Purpose of the Study:

  • To review the functions of mitophagy in mitochondrial quality and quantity control.
  • To summarize mitophagy's roles in fungal growth and pathogenesis over the past two decades.
  • To provide new perspectives on mitophagy in the context of fungal pathogenesis.

Main Methods:

  • Literature review of studies on mitophagy in fungi.
  • Analysis of molecular mechanisms underlying mitophagy in various fungal species.
  • Comparison of mitophagy functions across different organisms (mammals, yeast, pathogenic fungi).

Main Results:

  • Mitophagy is vital for maintaining mitochondrial health and cellular balance.
  • In pathogenic fungi, mitophagy influences spore production, vegetative growth, and virulence.
  • These roles diverge from those observed in mammalian cells and model yeasts.

Conclusions:

  • Mitophagy plays multifaceted roles beyond basic mitochondrial quality control, particularly in pathogenic fungi.
  • Understanding mitophagy in fungi offers insights into fungal biology and pathogenesis.
  • Further research into fungal mitophagy can reveal novel therapeutic targets.

Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

Autophagy01:27

Autophagy

Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

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...

The Inner Mitochondrial Membrane01:28

The Inner Mitochondrial Membrane

The inner mitochondrial membrane is the primary site of ATP synthesis. The inner membrane domain that forms a smooth layer adjacent to the outer membrane is called the inner boundary membrane. This domain contains membrane transporters that drive metabolites in and out of the mitochondria.  In contrast, the inner membrane network that invaginates into the matrix space is called the cristae membrane. This domain accounts for principle mitochondrial function as it accommodates the protein...

Delivery Pathways to the Lysosome01:36

Delivery Pathways to the Lysosome

Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized...
