Area of Science:

  • Virology
  • Infectious Diseases
  • Pathophysiology

Background:

  • Severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) causes COVID-19.
  • Understanding viral mechanisms and identifying therapeutic targets necessitates accurate infection models.

Purpose of the Study:

  • To review and analyze diverse SARS-CoV-2 infection models.
  • To discuss the advantages and disadvantages of each model for recapitulating in vivo pathophysiology.

Main Methods:

  • Review of existing literature on Vero cells, human cell lines, organoids, and animal models for SARS-CoV-2 infection.
  • Comparative analysis of model systems based on their ability to mimic in vivo viral infection.

Main Results:

  • Various models (Vero cells, human cell lines, organoids, animal models) exist for studying SARS-CoV-2.
  • Each model possesses unique strengths and limitations in replicating the disease's in vivo characteristics.

Conclusions:

  • Selection of appropriate infection models is crucial for advancing COVID-19 research.
  • Knowledge of model systems aids in developing effective strategies against emerging infectious diseases.
