background: stem cells from human exfoliated deciduous teeth (shed) have the capability to differentiate into neural cells. neurotrophins including nerve growth factor (ngf), brain-derived neurotrophic factor (bdnf), neurotrophin-3 (nt-3), and neurotrophin-4 (nt-4) have neurogenesis, neurotrophic, or neuroprotective effects and are expressed in developing teeth. the aim of this study was to mea...

Nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and neurotrophin-3 (NT-3) are three representative neurotrophins responsible for the differentiation and survival of neurons, and their high-affinity receptors are tropomyosin-receptor-kinase (TRK)A, TRKB, and TRKC, respectively. In this study, we investigated the expression of neurotrophins in a mouse periodontal ligament cel...

The neurotrophins NGF, BDNF, NT-3 and NT-4 have a wide range of effects in the development and regeneration of neural circuits in the visual system of vertebrates. This review focuses on the localization and functions of neurotrophins in the retina, lateral geniculate nucleus, suprachiasmatic nucleus, superior colliculus/optic tectum, and isthmic nuclei. Research of the past 20 years has shown ...

Neurotrophins, secreted in an activity-dependent manner, are thought to be involved in the activity-dependent refinement of synaptic connections. Here we demonstrate that in hippocampal neurons and the rat pheochromocytoma cell line PC12 application of exogenous neurotrophins induces secretion of neurotrophins, an effect that is mediated by the activation of tyrosine kinase neurotrophin recepto...

Neurotrophins are synthesized first as precursors, followed by maturation through proteolytic removal of the "pro" region. Since pro- and mature neurotrophins elicit opposite functional effects by differential interactions with Trks and p75 receptors, extracellular cleavage represents a new way to control the synaptic functions of neurotrophins. A single nucleotide mutation in the pro-region ap...

nature neuroscience • volume 2 no 4 • april 1999 Activity-dependent synaptic modifications are crucial to the normal development and function of the nervous system, but the basic underlying mechanisms are not fully understood. Recently, it has been proposed that activity-dependent synaptic plasticity may involve a family of secreted proteins known as neurotrophins1–5. Neurotrophins were initial...

Recent studies have established that neurotrophin synthesis and secretion are regulated by activity and that these factors are involved in activity-dependent processes in the nervous system. Neurotrophins also are known to induce increases in intracellular calcium, a trigger for regulated secretion. This finding raises the possibility that neurotrophins themselves may stimulate regulated secret...

Neurotrophins have been previously mentioned as potential factors that may alter human growth and result in fetal restriction (FGR). As neural factors, neurotrophins promote brain development plasticity a significant effect on the synaptic transmission, although actual mechanisms of their action not completely investigated. Several articles published this field denoting importance biomarkers de...
