VSIG4 and infection: Myeloid dendritic cells in dormant infections also showed notable differences in mRNA expression, affecting neutrophil recruitment (C1QA, C1QB, ITGAM), immune checkpoint regulation (IFITM2, IFITM3, CST7, THBS1), and T-cell response (VISIG4, V-set immunoglobulin domain containing 4) (Fig. 4C).
