Necrosis

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 Death

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...

Autophagic Cell Death

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...

Mitochondrial Membranes

Mitochondrial Membranes

A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...

Electron Transport Chain: Complex I and II

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Mitochondria

Mitochondria

Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Background:

Neurodegenerative diseases involve neuron death, leading to motor and cognitive decline.
Currently, no cures exist; treatments focus on symptom management.
Mitochondrial dysfunction is implicated in the pathogenesis of most neurodegenerative disorders.

Purpose of the Study:

To review the role of mitochondrial permeability transition (mPT) in neuronal death in major neurodegenerative diseases.
To identify inducers of mPTP opening in neurons, such as free radicals and calcium.
To discuss the challenges and prospects of developing neuroprotective strategies targeting mPTP inhibition.

Main Methods:

Literature review focusing on mitochondrial permeability transition.
Analysis of studies investigating neuronal death mechanisms in neurodegenerative diseases.
Examination of factors inducing mPTP opening, including oxidative stress and calcium overload.

Main Results:

Mitochondrial permeability transition (mPT) is an early event in both apoptotic and necrotic neuronal cell death.
mPT regulates tissue regeneration by causing irreversible cell loss in postmitotic neurons.
Free radicals and calcium are key inducers of mPTP opening in neurons.

Conclusions:

Mitochondrial permeability transition plays a critical role in neuronal demise across various neurodegenerative conditions.
Targeting mPTP opening presents a promising avenue for neuroprotection.
Further research is needed to overcome challenges in developing effective mPTP-inhibiting therapies.
