Several chemokines were also found to exhibit differential regulation with COVID-19 in the pregnant and non-pregnant states: CXCL10 and CCL22 were consistently increased or diminished, respectively, in both non-pregnant and pregnant cases; yet, CCL1 was reduced and CXCL13 was increased only in non-pregnant COVID-19 patients, although data from pregnant patients showed similar tendencies (Fig. 7k–n). This evidence concerns the gene CXCL10 and COVID-19.
