  1. 1 Intro
  2. 2 Single-cell data have identified some immune cell types that are expanded or depleted in autoimmunity
  3. 3 Modeling dynamic regulatory elements to find disease-critical cell states
  4. 4 Identifying cell-state-dependent peaks within each cell type using a continuous Poisson GLM framework
  5. 5 Example peak accessibility profiles reflect the nature of dynamic versus invariant peaks
  6. 6 Annotating the genome based on peak sets of interest
  7. 7 We can identify peak-gene-cell state trios associated with autoimmune diseases
  8. 8 Once we have identified a cell state of interest, how can we systematically learn its active gene regulatory programs?
  9. 9 Stochasticity: transcriptional bursting
  10. 10 Transcriptional heterogeneity is propagated from a TF to its target genes in sequential steps, each of which creates a time delay...
