From: A genetic algorithm-based boolean delay model of intracellular signal transduction in inflammation

Component

Boolean transfer function

IRAK1(t)

= 5*IL1(t-1) OR 3*LPS(t-87)

TAB1/TAB2/TAK1(t)

= IRAK1(t-13) OR LPS(t-125)

NIK(t)

= TAB1/TAB2/TAK1(t-25) OR TNFR1(t-1)

IKK(t)

= TAB1/TAB2/TAK1(t-100) OR NIK(t-1)

IkBa(t)

= NOT 2* IKK(t-3) OR -62* NFkB(t-96)

NFkB(t)

= NOT IkBa(t-1)

A20(t)

= 7*NFkB(t-107)

IL1(t)

= -62*NFkB(t-373)

TNF(t)

= -62*NFkB(t-69)

TNFR1(t)

= 4*TNF(t-1) AND NOT A20(t-10)

  1. Each component has a Boolean transfer function that contains logic gates and two type of parameters: delay activation (inside bracket) and sustained response (before * sign). Each time step corresponds to 30 second in real time
