“…In the course of infection, SARS-CoV2 impairs the normal responses of the immune system [ 3 ], causing lymphopenia, granulocyte and monocyte abnormalities, increased antibodies, overactivation of T helper (Th) 1 and Th17 cells, dysregulation of regulatory T (Treg) cells, and overproduction of proinflammatory cytokines, especially in severe and critical cases. Disrupted control of the immune system increases the level of inflammatory cytokines, including interleukin (IL)-1β, IL-2, IL-6, IL-7, IL-8, IL-10, granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interferon gamma-induced protein 10 (IP-10), and monocyte chemoattractant protein 1 (MCP1) leading to cytokine storm, a common occurrence side effect in diseases treated by chimeric antigen receptor T (CAR-T) cells [ 4 , 5 ]. Cytokine storm is a causative phenomenon of hyper inflammation and respiratory system injury in SARS-CoV2 infection [ 6 , 7 ].…”
