The immunomodulatory molecules included in this study, grouped according to their function(s) when in membrane-bound form.

Inhibitory	(Co-)stimulatory	Both
BTLA CTLA-4 E-cadherin IDO LAG-3 PD-1 PD-L1 PD-L2 TIM-3	4-1BB 4-1BBL APRIL BAFF CD27 CD28 CD40L Galectin-3 GITR MICA MICB	CD80 HVEM IL-2Rα

The colors represent the function of the molecule when in its membrane-bound form. Red, inhibitory, green, (co-) stimulatory, and blue, indicates that the molecule is either inhibitory or stimulatory, depending on which receptor the molecule binds to.
