To investigate whether ELP-P10 or SynB1-ELP-P10 treatment led to any strong immune activation or suppression at the level of circulating immune cells, peripheral immune cell analysis was performed using the blood collected at day 3 post-infection from MCMV-infected mice, treated with vehicle, SynB1-ELP, ELP-P10 or SynB1-ELP-P10. This evidence concerns the gene NR5A1 and infection.
