Neurotrophin and Neurotrophin Receptors in Human Fetal Kidney

Neurotrophin and Neurotrophin Receptor Involvement in Human Neuroblastoma

Trk receptors: mediators of neurotrophin action.

The four mammalian neurotrophins - NGF, BDNF, NT-3 and NT-4 - each bind and activate one or more of the Trk family of receptor tyrosine kinases. Through these receptors, neurotrophins activate many intracellular signaling pathways, including those controlled by Ras, the Cdc42/Rac/RhoG protein family, MAPK, PI3K and PLC-gamma, thereby affecting both development and function of the nervous system...

Neurotrophins and Neurotrophin Receptors in Proliferative Diabetic Retinopathy

Neurotrophins (NTs) are emerging as important mediators of angiogenesis and fibrosis. We investigated the expression of the NTs nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), and neurotrophin-4 (NT-4) and their receptors TrkA, TrkB, and TrkC in proliferative diabetic retinopathy (PDR). As a comparison, we examined the expression of NTs and their rece...

Neurotrophins and Neurotrophin Receptors in Adult Brain Plasticity

265 Neurotrophic factors stimulate survival and growth of neurons during development and are involved in the regulation of neuronal survival, plasticity and regeneration in the adult nervous system. These growth factors offer an avenue to develop effective therapy for disorders associated with degeneration and neuron loss. Earlier studies showed that nerve growth factor (NGF) protects basal for...
