Infection, Inflammation and Immunity in Covid-19 Infection

The COVID-19 pandemic caused by the SARS-CoV-2 has increased the burden on healthcare system. Despite some progress in its diagnostics has been made, effective prevention and treatment are still insufficient. Since SARS-CoV-2 infections often cause systemic inflammation and multiple organ failure, the therapeutic options aimed at modulating the host immune responses to prevent subsequent systemic complications are demanding. The review provides a summary of the SARS-CoV-2 virus infection and underlines the current perception of pulmonary host’s immune response and its contributions to disease severity and systemic inflammation. Signaling pathways which have the potential to manipulate host immunity and improve clinical outcomes are also presented.
