“…In other words, genes from different cell types may co-vary and therefore reside in the same gene module, thus providing a simplifying insight into how different cell types coordinate their behaviors. To capture such coordinated changes, we utilized Surprisal Analysis (Remacle et al, 2010;Zadran et al, 2014), which has been applied to consolidate multi-omics bulk and single-cell data (Kravchenko-Balasha et al, 2014Remacle et al, 2010;Su et al, 2017Su et al, , 2019Su et al, , 2020. The goal is to condense the changes of millions of correlated genes from different cell types into changes in just one major gene module or axis of expression, which contains the co-varying genes from all major immune cell types.…”
