“…Increased plasma concentrations of interleukin (IL), such as IL-1β, IL-2, IL-6, IL-7, IL-8, IL-10, or IL-17, interferon (IFN)γ, IFNγ-inducible protein 10, monocyte chemoattractant protein 1 (MCP1), granulocyte-macrophage colony-stimulating factor (GM-CSF), macrophage inflammatory protein 1α, and tumor necrosis factor-alpha (TNFα), among others, have been found as inflammatory mediators in COVID-19 [ 39 , 40 , 41 , 42 , 43 , 44 ]. Importantly, macrophages and neutrophils also play a potential pathological role during SARS-CoV-2 infection [ 33 ] by producing numerous ROS, including but not limited to H 2 O 2 , O 2 •− and hydroxyl radical ( • OH) [ 45 ]. Oxidative stress affects the immune system throughout altering immune cell function and inflammatory response [ 46 , 47 ].…”
