CCL7 and infection: Herein, we detected increased expression of marker genes such as Cd44, Ccl24, Ccl7, Cd74, S100a-related genes, Wnt10b in both infection by NF1_LV and NF45_HV and Cd36, Cd47, Mrc1, in particular for NF1_LV, indicating the presence of infiltrating macro/monophages during the infectious process (Figure 7, Step 2).
