Biostatic (nonvital) tissue allografts have been used for temporary replacement as well as to trigger, stimulate, and ensure space for the regeneration of a recipient's own tissues.
In the latter form, a uveal component, whether tissue damage or a microbial trigger, stimulates the generation of antigen-specific T cells and/or autoantibodies that are believed to play a pathogenetic role [[3]], hence the term autoimmune uveitis (AU).
In that line, triggering of the H1R on Tregs decreases their suppressive function which was associated with decreases in CD25 and FoxP3 expression [65] while H4R triggering stimulates Treg frequency [66] and migration and inhibits IL-12 and CCL2 secretion [67].
It is known that CD44 triggering stimulates diverse signalling pathways, including activation of ERK (Bourguignon et al, 2005), RAC (Teramoto et al, 2005), and RHO (Bourguignon et al, 2003), as well as secretion of soluble factors, like cytokines and metalloproteinases (Zhang et al, 2002; Bourguignon et al, 2003; Murphy et al, 2005).
We don't know exactly how they work; they may trigger or stimulate the body's own healing processes.
But the combination of old and recent photography and drawing, some of it surreal and some of it quite real, triggers a stimulating visual, often contemplative experience.
It has been reported that the occurrence of a mutualistic endophyte works as a "biological trigger" to stimulate the stress response system more efficiently than nonmutualistic plants [15].
All of them used myoelectric signal of orbicularis oculi at the normal side as the trigger to stimulate the paralyzed side.
Here we proposed that the myoelectric signal of levator palpebrae superioris could be used as the trigger to stimulate the paralyzed orbicularis oculi.
Sensitizing events may trigger and stimulate discursive renewal.
