Compound	p (-1100)	p (-203)	Reference
TSH	Decrease	Decrease	(13)
Hydrocortisone	Decrease	Decrease	(14)
Insulin/IGF-1	Decrease	Increase	(30)
α-and γ-Interferons	Increase	Increase	(14, 18)
Iodide	Decrease	Decrease	(15)
TGF-β1	Decrease	Decrease	(19)
Thymosin-α1	Increase	Increase	(20)

p(-1100) and p(-203) indicate a reporter vector containing respectively the full length (-1100 bp) or the deleted mutant (-203 bp) of the MHC class I promoter PD1. Data are from previous studies (13–15, 17–20, 30).
