Insights

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant can cause cardiovascular and gastrointestinal issues. This review examines SARS-CoV-2

Area of Science:

  • Virology and Immunology
  • Cardiovascular Medicine
  • Gastroenterology

Background:

  • The COVID-19 pandemic, caused by SARS-CoV-2, continues to evolve with new variants like Omicron.
  • While primarily respiratory, SARS-CoV-2 infection impacts multiple organs due to its binding to the ACE2 receptor.
  • The ACE2 receptor is highly expressed in the heart and gastrointestinal tract, making these organs susceptible to complications.

Purpose of the Study:

  • To conduct a literature review on cardiovascular and gastrointestinal complications associated with SARS-CoV-2 infection.
  • To summarize current knowledge on the Omicron variant's structural development and receptor binding.
  • To compare Omicron's interaction with human receptors and proteases against previous variants of concern (VOCs).

Main Methods:

  • Literature review of existing studies on SARS-CoV-2, COVID-19, and its variants.
  • Analysis of scientific data regarding the structural characteristics of the Omicron variant.
  • Comparative analysis of Omicron's binding affinities to human ACE2 and proteases versus prior VOCs.

Main Results:

  • SARS-CoV-2 infection leads to significant cardiovascular and gastrointestinal complications.
  • The Omicron variant exhibits high transmissibility and immune evasion capabilities.
  • Structural analysis reveals differences in Omicron's binding to human receptors and proteases compared to previous SARS-CoV-2 variants.

Conclusions:

  • COVID-19 complications extend beyond respiratory symptoms, affecting the cardiovascular and gastrointestinal systems.
  • Understanding the structural and binding characteristics of variants like Omicron is crucial for managing the pandemic.
  • Further research is needed to fully elucidate the long-term effects of SARS-CoV-2 on these vital organs.

Viral Recombination00:57

Viral Recombination

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.

Rous Sarcoma Virus (RSV) and Cancer

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.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Single Nucleotide Polymorphisms-SNPs

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,...

What is Monogastric Digestion?01:50

What is Monogastric Digestion?

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Viral Mutations00:36

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Psychoneuroimmunology: Cardiovascular Disease01:27

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
