Epilepsy is triggered in various parts of the brain, yet experts admit they're at a loss to pinpoint which zones are more influential.
NF- κB pathway can be triggered in dental pulp stem cells under various stimulating factors, that is, trauma, inflammatory factors, MTA, and estrogen [ 12– 15], in which tumor necrosis factor- α (TNF- α) is the putative classical pathway activator [ 4, 16, 17].
In plants, PA serves as a second messenger and is triggered in response to various biotic and abiotic stresses, including pathogen infection [ 77, 120], drought, salinity, wounding, cold, cell death [ 68, 70, 98] and oxylipin production [ 71– 71].
While this disruption could be triggered by various mechanisms, in the majority of cases changes in the structure or metabolism of NF-L, a subunit required for assembly of neurofilaments in vivo, play a crucial role (45, 62– 62).
That's triggering in my mind.
Cell suicide in protists can be triggered by various extra and intracellular events including nutrient deprivation, heat shock, drug treatment and the presence of nitric oxide (NO), reactive nitrogen species (RNS) and reactive oxygen species (ROS) (see for example reviews [11] [13]).
Differentiation of bloodstream forms into procyclic forms, which multiply in the midgut of the Tsetse fly (reviewed in [ 5]), can be triggered by various stimuli, including addition of cis-aconitate [ 6], acid treatment, proteolytic stress [ 7, 8] and glucose deprivation [ 9].
Endothelial dysfunction, one of the key factors of atherogenesis, can be triggered by various endothelium damaging factors present in lupus.
