This Progress article from Merad and Martin examines our current understanding of the excessive inflammatory responses seen in patients with severe COVID-19. The authors focus on the emerging pathological roles of monocytes and macrophages and discuss the inflammatory pathways that are currently being ...
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 ...
monocytes can move quickly (approx. 8-12 hours) to sites of infection in the tissues and divide/differentiate into macrophages and dendritic cells to elicit an immune response. Half of them are stored in the spleen. Monocytes are usually identified in stained smears by their large kidney shaped...
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, ...
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 ...
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]....
Macrophages then migrate from the blood towards peripheral nerves to phagocytize Schwann cells, damaging the myelin sheath and/or axon in the process4,5. In Europe and North America, approximately 90% of GBS cases are of the acute inflammatory demyelinating polyneuropathy (AIDP) subtype6. The ...

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) ...
