He also instigated a signal, a bugle call, to call on his crew to board an enemy vessel.
One possibility is that the short rhALR may instigate intracellular signaling coupled to cell proliferation similar to these mitogens (that is, EGF, TGF-α, or HGF).
Our data with brief agonist application (5s), sufficient to release Ca2+ from the SR but not instigate further signalling pathways, such as receptor operated channels, show that it is store operated Ca2+ entry that is activated and underlying the rise of Ca2+ stimulated when the SR is depleted.
Located on mammalian renal epithelia they sense renal tubular flow by bending, thus instigating intracellular signalling which maintains epithelial differentiation (12, 17– 17).
Reactive oxygen species (ROS) are essential during the healing process at multiple stages, ranging from the initial signal that instigates the immune response, to the triggering of intracellular redox-dependent signalling pathways and the defence against invading bacteria.
The need for a signal that instigates the behavioural change that leads to neural differentiation is demonstrated and potential mediators of this signal are explored through model analysis techniques.
Reactive oxygen species (ROS) are produced directly after tissue damage and are essential during various stages of the healing process, ranging from the initial signal that instigates the immune response to the defence against invading bacteria [1], [2].
It is plausible that the signal that instigates the behavioural change leading to the down-regulation of Hes1 is either the result of cross-talk with a different signalling pathway [3], [6], [7], [23] or the result of the combined effect of many processes [24].
These covalent modifications promote the binding of arrestins, which not only uncouple the receptors from heterotrimeric G proteins and target them for endocytosis but also instigate G protein-independent signaling pathways.
The expression of immunostimulatory motifs in this situation could produce a confounding signal that can instigate an autoimmune reaction of potentially catastrophic consequences for the host, such as a cytokine storm.
Hyperglycemia-induced ROS stimulates signal transduction to instigate inflammatory cytokines, e.g. TNF-α, IFN-γ and TGF-β [ 61].
