Once the coronavirus spreads enough, the cytokine storm in DS might have more severe consequence due to higher levels of chemokines (such as CXCL10), inducing chemotaxis and stimulation of monocytes, and Interleukin 10 (IL10), that even though it is classified as an anti-inflammatory interleukin, it recruits fibrocytes and activates M2 macrophages and may lead to later lung fibrosis. This evidence concerns the gene CXCL10 and pulmonary fibrosis.
