Of note, Ccl8 and Ccl2 as well as Cxcl9 and Cxcl10, chemoattractants for monocytes and T cells, respectively, were significantly up-regulated in the lungs of AR-infected mice and in COVID-19 patients (40–42), in line with the increased recruitment of these cells (Fig. 3I, Figure S9C and Data file S1). The gene discussed is CXCL9; the disease is COVID-19.
