Figures & data

Figure 1. Mechanisms of JEV neuroinvasion. The numbers in squares indicate the mechanisms of virus entry into the brain: 1, passive transport of virus particles across the endothelial cells; 2, diapedesis of infected leukocytes; 3, virus transport via the peripheral nervous system; and 4, virus transport through the BBB disrupted by inflammatory mediators released from cells of blood and brain sides of the BBB. The inflammatory mediators written in gray mediate the crosstalk between microglia, astrocytes, and neurons that may contribute to the BBB damage. The symbol “?” denotes the missing information in the literature. Created with the web-based BioRender tool (BioRender.com)
