2.3.13 Positive feedback and stability In Figure 2.76 a negative feedback signal is produced by using a series voltage. If the phase of the series voltage was changed such that the feedback signal augmented the input, then the nature of the feedback loop would become positive. With this po...
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...
feedback information from emotional changes. Thus, an ACCGlu–VTAGABA–VTADA–ACCGlupositive-feedback loop mediates the progression to and maintenance of persistent pain and comorbid anxiodepressive-like behavior. Disruption of this feedback loop relieves hyperalgesia and anxiodepressive-like behavior in...
With the support by the National Natural Science Foundation of China and the Ministry of Science and Technology of China,Prof.Song Erwei's laboratory at Sun Yat-Sen Memorial Hospital,Sun Yat-Sen University,reported that a positive feedback loop between mesenchymal-like cancer cells and macrophages...

Interestingly, in our study, the secretion of IL-6 by macrophages promoted the secretion of additional IL-6, which suggested that a positive feedback loop in TAMs promotes IL-6 secretion. In addition, IL-6 can activate the EMT pathway in lung adenocarcinoma and promote metastasis, whereas the...
