Table 2 Differences in PC scores and Euclidean distance (in the space defined by PC1 and PC2) between treatments and control (untreated cells) for costimulatory molecule expression. We observe a cluster of adjuvants (MPLA, LPS, CpG, and NP + Mi + CpG) that suggest greater upregulation of costimulatory molecule expression than the other adjuvants

From: “Just right” combinations of adjuvants with nanoscale carriers activate aged dendritic cells without overt inflammation
