Abstract:
The coronavirus disease 2019 (COVID-19) pandemic caused by SARS-CoV-2 has had devastating global impacts and will continue to have dramatic effects on public health for years to come. A better understanding of the immune response to SARS-CoV-2 will be critical for the application and development of therapeutics. The degree to which the innate immune response confers protection or induces pathogenesis through a dysregulated immune response remains unclear. In this review, we discuss what is known about the role of the innate immune system during SARS-CoV-2 infection, suggest directions for future studies, and evaluate proposed COVID-19 immunomodulating therapeutics.

Background:
- The COVID-19 pandemic, caused by SARS-CoV-2, has had profound global health consequences.
- The role of the innate immune response in SARS-CoV-2 infection, whether protective or pathogenic, is not fully understood.
- Developing effective therapeutics requires a comprehensive understanding of the immune response to SARS-CoV-2.
Purpose of the Study:
- To review current knowledge on the innate immune system's function during SARS-CoV-2 infection.
- To identify key areas for future research in COVID-19 immunology.
- To evaluate potential immunomodulating therapies for COVID-19.
Main Methods:
- Literature review of existing studies on innate immunity and SARS-CoV-2.
- Analysis of the mechanisms by which innate immune responses may influence COVID-19 outcomes.
- Evaluation of clinical and preclinical data on immunomodulatory treatments.
Main Results:
- The innate immune system plays a complex role in SARS-CoV-2 infection, with potential for both protection and detrimental inflammation.

01:21Introduction to Innate and Adaptive Immunity
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
