For the virus to replicate into the host cells in inserts its RNA into the cells like monocytes and macrophages and takeovers the cellular machinery to produce new virions. COVID-19 patients exhibit clinical symptoms such as fever, nonproductive cough, dyspnea, myalgia, fatigue, and radiographic ...
We will focus on monocytes; however, since monocyte function is interlinked with that of macrophages and dendritic cells, the latter populations will also be discussed. We will highlight the role of monocytes in the context of individual diseases and discuss how therapeutics impact them. Finally, ...
Lung injury in the exudative phase begins with the activation of alveolar macrophages by microbial or cellular injury products. Cytokines and chemokines released by macrophages and lymphocytes recruit and activate circulating neutrophils. Activated neutrophils contribute to injury by releasing mediators [2]....
monocytes are produced in yourbone marrowand then enter your bloodstream. After a few hours, monocytes move from your blood into your lung, liver, or spleen tissue where they develop into macrophages. These are scavenger cells that fight certain infections, destroy cancer cells, and help other ...
Recently it has been shown that cleared MSCs are associated with circulating monocytes and tissue-resident macrophages [32, 39, 40]. From this observation a new mechanism of action has been hypothesized: efferocytosis. Efferocytosis is the body’s natural mechanism for clearing dead and dying cells...

Patients with severe COVID-19, monocytes/macrophages may be the main source of uncontrolled levels of the pro-inflammatory mediators TNF-α and IL-6 in the respiratory tract in peripheral blood4. Plasmatic levels of IL-6 have been associated with mortality, intensive care admission and ...

In silico analyses predicted GRP78, which is constitutively expressed on monocytes and macrophages, to be a potential candidate receptor for SARS-CoV-2 virus entry. Methods Hospitalized COVID-19 patients were characterized regarding their pro-inflammatory state and cell surface GRP78 (csGRP78) ...
