Coupled positive and negative feedback circuits form an essential building block of cellular signaling pathways
Article Abstract:
The role of positive and negative feedback loops are explored to understand the complex regulatory mechanism of cellular signaling systems caused by feedback loops. The coupled feedback loops have enabled cellular systems to produce perfect responses to noisy stimuli with respect to signal duration and amplitude, suggesting that the coupled positive and negative feedback loops form essential signal transduction motifs in cellular signaling systems.
