Double-Positive T Cells (IMAGE)
Caption
Dengue-specific CD4 cells have both a pro-inflammatory function and an anti-inflammatory function, which is typically not seen in acute viral infections. Each dot is a double positive cell with the color of each dot representing the expression level of a protein named TIGIT, which is an inhibitory immunoreceptor, in each cell.
