For instance, this compound might act against bacteria and fungi responsible for secondary infections in COVID-19 patients [10]; lysozyme could have beneficial effects in counteracting pathological features occurring in severe COVID-19 infections (e.g., neutrophil infiltration, macrophage activation, free iron overload, oxidative stress, advanced glycation end-product (AGE) effects, excessive proinflammatory cytokine production, and thrombus formation); and its immunomodulatory properties might promote the resolution of inflammation. Here, LYZ is linked to COVID-19.
