Abstract:
As the outbreak of the new coronavirus (SARS-CoV-2) infection is spreading globally, great effort is being made to understand the disease pathogenesis and host factors that predispose to disease progression in an attempt to find a window of opportunity for intervention. In addition to the direct cytopathic effect of the virus, the host hyper-inflammatory response has emerged as a key factor in determining disease severity and mortality. Accumulating clinical observations raised hypotheses to explain why some patients develop more severe disease while others only manifest mild or no symptoms. So far, Covid-19 management remains mainly supportive. However, many researches are underway to clarify the role of antiviral and immunomodulating drugs in changing morbidity and mortality in patients who become severely ill. This review summarizes the current state of knowledge on the interaction between SARS-CoV-2 and the host immune system and discusses recent findings on proposed pharmacologic treatments.
Insights
This review examines how the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) interacts with the human immune system. It highlights the role of hyper-inflammation in severe COVID-19 and discusses potential drug treatments.
Area of Science:
- Immunology
- Virology
- Pharmacology
Background:
- The global spread of SARS-CoV-2 necessitates understanding disease pathogenesis.
- Host immune response, particularly hyper-inflammation, is critical in determining COVID-19 severity.
- Current COVID-19 management is primarily supportive, with ongoing research into therapeutic interventions.
Purpose of the Study:
- To review the current knowledge on SARS-CoV-2 and host immune system interactions.
- To discuss recent findings on potential pharmacologic treatments for severe COVID-19.
Main Methods:
- Literature review of current research on SARS-CoV-2 pathogenesis.
- Analysis of clinical observations regarding disease progression.
- Summary of studies on antiviral and immunomodulating drug efficacy.
Main Results:
- SARS-CoV-2 infection triggers a complex immune response.
- Hyper-inflammation significantly contributes to severe disease and mortality.
- Several antiviral and immunomodulating agents are under investigation for therapeutic potential.
Conclusions:
- Understanding the interplay between SARS-CoV-2 and the immune system is crucial for effective treatment strategies.
- Pharmacologic interventions targeting the immune response may reduce COVID-19 morbidity and mortality.
- Further research is needed to establish the role of specific drugs in managing severe illness.

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...
Conjugated Proteins
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
