Accordingly, expression of Cxcl9, Cxcl10, and Cxcl16 was increased earlier, at 14 days after infection in lungs of C57BL/6 compared with C3HeB/FeJ mice (Fig. 4 c), with expression most pronounced in macrophages, conventional dendritic cells (cDCs), and, in the case of Cxcl10, neutrophils (Fig. 4 d and Fig. S2 b). The gene discussed is CXCL10; the disease is infection.
