The Inner Mitochondrial Membrane

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...

Cystic Fibrosis: Pathogenesis

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

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,...

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,...

COPD: Pathogenesis and Clinical Features

COPD: Pathogenesis and Clinical Features

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Biochemistry
Pathology
Immunology

Background:

COVID-19, caused by SARS-CoV-2, presents with severe respiratory failure and systemic complications.
The "cytokine storm" and iron dysregulation (hyperferritinemia) are associated with disease severity.
Mitochondria play a crucial role in cellular oxidative homeostasis and are implicated in COVID-19 pathology.

Purpose of the Study:

To discuss cellular and systemic events impacting mitochondrial function in COVID-19.
To explore the link between SARS-CoV-2 infection, oxidative stress, and disease progression.
To identify potential therapeutic targets for reducing COVID-19 severity.

Main Methods:

Review of existing literature on COVID-19 pathogenesis.
Analysis of the role of iron dysregulation and oxidative stress.
Examination of mitochondrial dysfunction and its consequences.

Main Results:

SARS-CoV-2 infection triggers systemic inflammation and oxidative stress.
Iron dysregulation and mitochondrial dysfunction contribute to platelet damage and thrombosis.
Mitochondrial oxidative stress may exacerbate inflammation and impact microbiota.

Conclusions:

Understanding the impact of SARS-CoV-2 on mitochondrial function is critical for COVID-19 pathogenesis.
Interventions targeting iron metabolism and oxidative stress may offer therapeutic benefits.
Further research into these mechanisms could lead to novel treatments for severe COVID-19.
