Cell lysates were collected from the joints of mice infected with WT CHIKV or CHIKV nsP-mutants at 15 hpi, 2 dpi or 6 dpi (n=5 per group). The concentrations of 36 immune mediators were quantified using a 36-plex microbead-based immunoassay. Immune mediators are grouped based on function. Each color represents the relative concentration of a particular analyte. Blue and red indicates low and high concentration, respectively.
