Summary
The novel SARS-CoV-2 virus may be neuroinvasive and potentially trigger central nervous system conditions like multiple sclerosis (MS). Research explores mechanisms like molecular mimicry and blood-brain barrier disruption in coronavirus-induced demyelination.
Area of Science:
- Neuroscience
- Virology
- Immunology
Background:
- The SARS-CoV-2 pandemic poses global health challenges.
- SARS-CoV-2 is primarily respiratory but shows neuroinvasive potential.
- Coronaviruses have been implicated in central nervous system diseases, including demyelination.
Purpose of the Study:
- To investigate the potential role of SARS-CoV-2 in the pathology of multiple sclerosis (MS).
- To explore the mechanisms by which SARS-CoV-2 might induce central demyelination.
Main Methods:
- Review of existing literature on coronavirus neuroinvasion and MS pathology.
- Analysis of proposed mechanisms including molecular mimicry, blood-brain barrier disruption, and inflammatory responses.
Main Results:
- SARS-CoV-2 exhibits neuroinvasive properties.
- Several mechanisms, including molecular mimicry and inflammatory cytokine dysregulation, are implicated in coronavirus-induced demyelination.
- Upregulation of matrix metalloproteinases may contribute to central demyelinating pathology.
Conclusions:
- SARS-CoV-2 may act as a novel risk factor for developing MS.
- Further research is needed to confirm the direct link between SARS-CoV-2 infection and MS development.

5.5K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

01:26Factors Affecting the Risk of Infection
12.6K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

16.4K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

00:57Viral Recombination
23.9K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

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,...

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...
