According to the heat map generated, several chemokines and receptors were elevated in the high-CRS subgroup (e.g., chemokine (C–C motif) ligand (CCL) 5, C-X-C chemokine receptor type (CXCR) 4, CXCL9, CXCL14, CCL18, CCL21, CXCL11, and CXCL12), which may promote the infiltration of immune cells, such as CD8+T cells and dendritic cells (DCs) (Figure 6(a)). Here, CXCL9 is linked to congenital rubella syndrome.
