Table 1. Enrichment p-values of antigen-presenting cell (APC) versus T cell interactions associated with type 1 diabetes.

APCs	T cells (E034)	Th naive (E038)	Th memory (E040)	Treg (E044)
Fetal thymus (E093)	0.55	0.81	0.50	0.22
Monocytes (E029)	4.9 × 10−4	0.016	2.7 × 10−4	4.2 × 10−6
B cells, PB (E032)	8.4 × 10−9	1.4 × 10−5	4.4 × 10−9	2.7 × 10−12
B cells, CB (E031)	1.8 × 10−5	2.9 × 10−3	1.3 × 10−5	7.5 × 10−8

The p-values signify the over-representation of interacting single-nucleotide polymorphism pairs active in each cell type combination. See Fig 4B. Shown in parentheses are the epigenome codes. PB, peripheral blood; CB, cord blood.
