Cytokine Storm

Caption

This is a microscopic photo of a blood smear from a transgenic mouse that mimics the human immune disorder, secondary HLH (hemophagocytic lymphohistiocytosis). The image shows macrophage immune cells (indicated by arrow) flooding healthy tissue cells during a cytokine storm caused by HLH in a very similar fashion t what occurs in patients with severe COVID-19 disease. Researchers reporting in the Journal of Allergy and Clinical Immunology say the HLH data were a factor in a decision to test the anti-inflammatory drug ruxolitinib (used to treat secondary HLH) in patients with COVID-19 in China.
