Abstract:
Type 1 interferons have a broad antiviral activity in vitro and are currently evaluated in a clinical trial to treat MERS-CoV. In this review, we discuss preliminary data concerning the potential activity of type 1 interferons on SARS-CoV-2, and the relevance of evaluating these molecules in clinical trials for the treatment of COVID-19.
Insights
Type 1 interferons show antiviral promise against coronaviruses. Preliminary data suggests these interferons may be effective for treating COVID-19 and warrant clinical evaluation.
Area of Science:
- Virology
- Immunology
- Infectious Diseases
Background:
- Type 1 interferons exhibit broad-spectrum antiviral properties in laboratory settings.
- These interferons are under investigation for Middle East Respiratory Syndrome Coronavirus (MERS-CoV) treatment.
Purpose of the Study:
- To review preliminary data on the efficacy of type 1 interferons against SARS-CoV-2.
- To assess the relevance of clinical trials for type 1 interferons in treating COVID-19.
Main Methods:
- Review of preliminary scientific data.
- Analysis of existing clinical trial information for MERS-CoV.
Main Results:
- Preliminary data suggests potential antiviral activity of type 1 interferons against SARS-CoV-2.
- The evaluation of type 1 interferons in clinical trials for COVID-19 is deemed relevant.
Conclusions:
- Type 1 interferons demonstrate potential as a therapeutic strategy for COVID-19.
- Further clinical investigation of type 1 interferons for SARS-CoV-2 is warranted.

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

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...
