Fig. 2From: Multiscale positive feedbacks contribute to unidirectional gastric disease progression induced by helicobacter pylori infectionDynamic change of Nf-κB and Shh following HP infection. a Temporal simulations of IkB proteins (black curve), Nf-κB(blue), and Nf-κB target genes (red) after induction of HP (at T = 5 h). b Temporal simulations of stomach acid (red), Sonic Hedgehog (Shh, black), and Interleukin-1 family of cytokines (IL-1, blue) after HP infection. c Temporal simulations of transforming growth factor beta (TGF-B, blue), BMMSC (red), and Shh (black) following HP infection. d The black curve shows the steady states of Shh as IL-1 level changes. TGF-β is set to be zero in this computation. The red curve shows the temporal changes of IL-1 and Shh from (b)Back to article page
