People can either control the danger elicited by the threat by making a positive and conscious shift in attitude and behaviour (called protective motivation or danger control responses).
All cell types can recognize toxic, metabolic, infectious, mechanic or osmotic types of danger and elicit primary signals that trigger defense mechanisms and that alert other cells.
Much less is known about the contribution of these effector mechanisms to the response against aberrant tissues and whether Drosophila uses internal cues, which indicate damage or danger to elicit immune responses.
For all its thematic ambitions, though, this is still at bottom a musical about musicians who can't play, and the danger of eliciting condescending laughter at the Wiggin girls' halting musical efforts remains real.
When the neutral stimulus (the rock or the sound of an airplane) later occurs, it automatically activates the amygdala like the original danger did, eliciting fear, and also triggers worry — anxiety.
When the tissue is exposed to danger signals elicited by pathogens, allergens or tumor cells, the epithelium or other innate immune cells produce many cytokines.
Development of the immune system has led to sophisticated decoding of danger signals elicited by incursion of foreign bodies, and retaliatory responses are adjusted accordingly.
In addition, the uncontrolled feeling of anxiety and fear transferred by parents to the child can cause these patients to treat each meal as a "recurrent danger", thereby eliciting a bad relationship with food.
The 'low-road' affective process is highly evolutionary and is designed to protect individuals from life-threatening danger, and to elicit defensive responses without conscious thought.
As ubiquitous and bacterial derived products, HSP-derived peptides are in fact perceived as a "danger" signal and elicit a default pro-inflammatory physiologic response.
