A subsequent in vitro study showed that a specific SARS-CoV protein, 3a/X1, directly promotes osteoclastogenesis, accelerating osteoclast differentiation from monocyte/macrophage precursors, enhancing the expression of receptor activator of NF-kB ligand (RANKL) and inflammatory cytokines such as TNF-α, which indirectly promote osteoclastogenesis [20] . As will be explained later in the text, IL-6 represents an important cofactor for bone resorption in inflammatory diseases; therefore, during SARS-CoV-2 infection, men, though less affected by osteoporosis, may experience more bone metabolism alterations than women for higher levels of IL-6 resulting from the lack of suppression by estrogen. ./cache/cord-343919-n8884bli.txt ./txt/cord-343919-n8884bli.txt
