Overview of SARS-CoV-2 Infection and Its Potential Reactions
Context:
The immunopathology of SARS-CoV-2 infection in COVID-19 is not well described yet, especially regarding dysregulation of the immune system. In this mini-review, current knowledge about the SARS-CoV-2 infection and immunopathogenesis of COVID-19 disease is described. We also discuss possible induced reactions against SARS-COV-2.
Evidence Acquisition:
Based on the authors' experience and knowledge, the current review aimed to, firstly, discuss and overview SRAS-CoV-2 infection and reactions in the body, and, secondly, to obtain related subjects from the PubMed database.
In most COVID-19 patients, uncontrollable cytokines secretion and mediators are major key points in the pathogenesis of the disease. Of all cytokines and mediators, serum levels of IL-6, IL-1β, TNF-α, IL-8, and soluble TNF-α receptor (sTNFR) have been reported. Lymphopenia and hypoxia, as well as the severity of the disease, can be considered as COVID-19 manifestations. High levels of intracellular NO inside of the red blood cells (RBCs) of patients drive the unexpected silent hypoxia phenotype induced ARDS importantly related to the patient's immune system dysfunction.
