However, despite relevant safety advantages, such vaccine strategies are not always effectively processed by antigen presenting cells and presented to the adaptive immune system, lacking "danger" signals necessary to trigger activation of the innate system and, downstream, of the adaptive immune response [ 50].
In 2010 a pastor, Martin Ssempa, showed videos in his church of gay people having sex in a bid to convince his congregation of the dangers and to try to trigger disgust about gays.
Similarly, the toward-torso cue might potentially be expected to trigger a "danger-approaching" signal in the brain, thus inducing a higher level of urgency and thus give rise to an alerting effect, which may encourage an organism (in this case, the driver) to avoid the danger.
Some evidence has pointed succinate as an 'alarming' signal able to trigger GPR91 to sense immunological danger, causing increased allograft rejection during organ transplantation [ 21].
Thus, original studies posited that HMGB1 functions as a cytokine to trigger responses via interaction by receptors used by other danger molecules such as TLR ligands.
At issue is whether such screening tests actually save lives or merely lead to diagnoses of more tumors that may pose little danger to a patient and trigger unnecessary treatment.
Microbial components and endogenous danger signals trigger the activation of signaling cascades leading to induction of the NF-κB system during sepsis.
This article originally appeared on VICE US.
He said he recalled his training, decided that from her distance of about 20 feet she was no danger to him, and chose not to pull the trigger.
A high density of positive charges close to cell surface is likely to be recognized as a signal of danger by cells or contribute to trigger cascades that are classically activated by endogenous cationic compounds.
