Immunouniverse of SARS-CoV-2

Area of Science:

• Immunology
• Virology
• Pathology

Background:

• Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes millions of global deaths.
• COVID-19 presents with diverse clinical features, from asymptomatic to critical illness.
• SARS-CoV-2 can dysregulate the host immune response, leading to severe immunopathology.

Purpose of the Study:

• To review the complex interaction between SARS-CoV-2 and the host immune system.
• To elucidate the mechanisms of immune response in host defense against SARS-CoV-2.
• To identify potential therapeutic targets for eliminating the virus.

Main Methods:

• Literature review focusing on SARS-CoV-2 and immune system interactions.
• Analysis of molecular mechanisms driving hyperinflammation and hypercoagulation.
• Exploration of factors contributing to pneumonia and acute respiratory distress syndrome (ARDS).

Main Results:

• SARS-CoV-2 infection triggers significant immune dysregulation.
• Specific molecular expressions at infection sites contribute to hyperinflammation and hypercoagulation.
• Pneumonia and ARDS are identified as primary drivers of mortality in severe COVID-19.

Conclusions:

• Understanding SARS-CoV-2 immunopathogenesis is crucial for effective treatment strategies.
• Targeting immune dysregulation may offer novel therapeutic avenues for COVID-19.
• Further research into host-virus interactions can guide the development of antiviral therapies.
