What is Positive Feedback in Biology? Negative feedback is not the only type of feedback control that exists. The human body also uses positive feedback loops. In positive feedback, the signal continues to be amplified. The relationship between the signal and the response to the signal is ...
Positive feedback loops are commonly seen in developmental pathways, which keep a developmental action silent in fluctuating background signals but trigger a robust response upon real stimuli at the right time and place. Although microRNAs are thought to be a mechanism as important as transcription ...
Positive feedback loops are common regulatory elements in metabolic and protein signalling pathways. The length of such feedback loops determines stability and sensitivity to network perturbations. Here we provide a mathematical analysis of arbitrary length positive feedback loops with protein production an...
The two element mutual activation and inhibitory positive feedback loops are a common motifs that occur in many biological systems in both isolated and interlocked form, as for example, in the cell division cycle and thymus differentiation in eukaryotes. The properties of three element interlocked po...
If feedback loops do in fact exist, then they have to be embodied by particular cell types and inflammatory mediators that communicate among these cells. In addition, specific antigens have to be incorporated as initiators and sustainers of the reaction. Connections, and the forces that ...
Cell signaling systems that contain positive-feedback loops or double-negative feedback loops can, in principle, convert graded inputs into switch-like, irreversible responses. Systems of this sort are termed ‘bistable’. Recently, several groups have engineered artificial bistable systems into Escheri...

Accumulation evidence showed that more and more non-coding RNA-associated positive feedback loops have been excavated to be closely related to tumorigenesis and progression [20, 21]. As the CTCF expression was positive correlated with circESRP1 level, we were curious whether CTCF/circESRP1 pathway...
