    Snippet: Previous research in SARS suggested that SARS-CoV regulates immune function-related gene expression in myeloid cells [27] and a report in a SARS-CoV-infected mouse model showed that dysregulated inflammatory and interferon responses of monocyte/macrophage cells caused lethal pneumonia [28] . Clinical data about COVID-19 suggest that peripheral innate immune monocyte cells and lung tissues macrophage cells are critically involved in host response .....
    Document: Previous research in SARS suggested that SARS-CoV regulates immune function-related gene expression in myeloid cells [27] and a report in a SARS-CoV-infected mouse model showed that dysregulated inflammatory and interferon responses of monocyte/macrophage cells caused lethal pneumonia [28] . Clinical data about COVID-19 suggest that peripheral innate immune monocyte cells and lung tissues macrophage cells are critically involved in host response and severe disease course [29] . Together, these findings suggest that modulation of myeloid cells may have an impact on SARS-CoV-2-related host responses. Interestingly, research on HCQ suggest that it may impact TLR signaling, antigen presentation, and alter macrophage function [30] . HCQ is also proposed to indirectly have anti-inflammatory effects upon the immune system.
