2.1.2 Positive feedback In a device with a positive feedback loop, the part of voltage returned from the output to the input is added to the input voltage, as shown in Figure 2.3. Sign in to download full-size image Figure 2.3. Organization of positive feedback This system may very rap...
In the context of a positive feedback loop, small changes in tuning based on genetic factors could be amplified, converting a transient response into one that is sustained and pathogenic. In addition, the immune response to foreign antigens is typically limited by the clearance of those antigen...

Taken together, this study elucidates the role and mechanisms of PAFR/YAP1 positive feedback loop in cardiac fibrosis, suggesting a potential role of this pathway as novel therapeutic targets in cardiac fibrosis.Similar content being viewed by others Cardiac Wnt5a and Wnt11 promote fibrosis by the...
Here, we identified a microenvironment with high IL-6 expression in lung cancer, and TAMs are one of the major sources of IL-6. By stimulating the JAK2/STAT3-C/EBPβ-IL6 pathway, IL-6 can promote the release of additional IL-6, creating a positive feedback loop in TAMs; thus, it ...
Discuss negative feedback mechanisms. Give a specific example of one. What is a negative feedback mechanism? What is your response to the climate change debate? In your opinion, how should we balance any possible uncertainty in science with the possibility of great ...
Liver metastasis is the leading cause of death in patients with colorectal cancer (CRC). Emerge evidence suggests that circular RNA (circRNA) is a pivotal player in cancer progression. However, its role in CRC liver metastasis remains largely unknown. Ci
Thus, our results suggest that Bem1 functions in a positive feedback loop: local activation of Cdc24 produces Cdc42-GTP, which recruits Bem1. In turn, Bem1 stabilizes Cdc24 at the site of polarization, leading to apical growth. 展开 ...
