1. Neurotrofinas na epilepsia do lobo temporal
INTRODUÇÃO: A neurotrofinas NGF, BDNF, NT-3 e NT-4 são os principais representantes da família das neurotrofinas no sistema nervoso central de mamíferos. Estão presentes em estágios específicos do crescimento e sobrevivência neuronal como a divisão celular, diferenciação e axogênese e também nos processos naturais de morte celular neuronal. A a

2. Comparison of the effect of ganglioside GM1 and the Nerve Growth Factor (NGF) on the expression of receiver of high affinity for NGF, TrkA and insulin in isolated pancreatic islets of NOD mice (non obese diabetic) / Comparação dos efeitos do gangliosideo GM1 e do fator de crescimento neural (NGF) sobre a expressão de receptor de alta afinidade para NGF, TrkA e insulina em ilhotas pancreaticas isoladas de camundongos NOD (diabetico não obeso)
The non-obese diabetic mice (NOD) lineage is characterized by developing type 1 diabetes mellitus (DM-1) naturally, bearing a similarity to DM-1 in human beings. The spontaneous manifestation of diabetes is characterized by gradual infiltration in pancreatic islets by mononuclear cells lymphocytes T (CD4+ and CD8+) and destruction of the ß-cells producers o

3. Effects of GM1 administration on autoimmune diabetes modulation and cytokines expression, Nerve Growth Factor and TrkA receptor in NOD mice (non obese diabetic) / Avaliação dos efeitos da administração do gangliosideo GM1 na modulação do diabetes mellitus autoimune e expressão de citocinas, Nerve Growth Factor e seu receptor TrkA em camundongos NOD (non obese diabetic)
The strain of NOD mice (non obese diabetic) spontaneously develops diabetes mellitus type 1 (DM-1) with strong similarity to the observed in humans. In this model, the diabetes manifestation occurs among 12th and 24th weeks of life, with presence of pancreas-specific autoantibodies. Great part of the cells are CD4+ and CD8+T cells, and even so NK cells, lymp

4. An alternatively spliced form of the nerve growth factor receptor TrkA confers an enhanced response to neurotrophin 3.
TrkA, a member of the receptor tyrosine kinase family, binds nerve growth factor (NGF) and subsequently activates intracellular signaling pathways. Previous studies have found variable and weak interaction of the TrkA receptor with neurotrophin 3 (NT-3), another member of the NGF family. TrkA is expressed in two splice forms, differing in the presence of an

5. TrkA Immunoglobulin-Like Ligand Binding Domains Inhibit Spontaneous Activation of the Receptor
The extracellular region of the nerve growth factor (NGF) receptor, TrkA, contains two immunoglobulin (Ig)-like domains that are required for specific ligand binding. We have investigated the possible role of these two Ig-like domains in receptor dimerization and activation by using different mutants of the TrkA extracellular region. Deletions of each Ig-lik

6. TrkA cross-linking mimics neuronal responses to nerve growth factor.
TrkA, a tyrosine kinase receptor, is an essential component of the nerve growth factor (NGF) response pathway. The binding of NGF to the receptor induces receptor autophosphorylation and activation of intracellular signaling pathways, resulting in diverse biological effects. We prepared polyclonal antibodies against the entire extracellular domain of rat trk

7. GIPC and GAIP Form a Complex with TrkA: A Putative Link between G Protein and Receptor Tyrosine Kinase Pathways
NGF initiates the majority of its neurotrophic effects by promoting the activation of the tyrosine kinase receptor TrkA. Here we describe a novel interaction between TrkA and GIPC, a PDZ domain protein. GIPC binds to the juxtamembrane region of TrkA through its PDZ domain. The PDZ domain of GIPC also interacts with GAIP, an RGS (regulators of G protein

8. Identification and Characterization of an Activating TrkA Deletion Mutation in Acute Myeloid Leukemia
In this study, we utilized retroviral transfer of cDNA libraries in order to identify oncogenes that are expressed in acute myeloid leukemia (AML). From screens using two different cell types as targets for cellular transformation, a single cDNA encoding a variant of the TrkA protooncogene was isolated. The protein product of this protooncogene, TrkA, is a r

9. Interaction of Mint2 with TrkA Is Involved in Regulation of Nerve Growth Factor-induced Neurite Outgrowth*
TrkA receptor signaling is essential for nerve growth factor (NGF)-induced survival and differentiation of sensory neurons. To identify possible effectors or regulators of TrkA signaling, yeast two-hybrid screening was performed using the intracellular domain of TrkA as bait. We identified muc18-1-interacting protein 2 (Mint2) as a novel TrkA-binding pro

10. A TrkA-to-p75NTR molecular switch activates amyloid β-peptide generation during aging
Aging is the single most important risk factor for AD (Alzheimer's disease). However, the molecular events that connect normal aging to AD are mostly unknown. The abnormal accumulation of Aβ (amyloid β-peptide) in the form of senile plaques is one of the main characteristics of AD. In the present study, we show that two members of the neurotrophin receptor

11. A signaling organelle containing the nerve growth factor-activated receptor tyrosine kinase, TrkA
The topology of signal transduction is particularly important for neurons. Neurotrophic factors such as nerve growth factor (NGF) interact with receptors at distal axons and a signal is transduced by retrograde transport to the cell body to ensure survival of the neuron. We have discovered an organelle that may account for the retrograde transport of the neu

12. SH2-B and APS Are Multimeric Adapters That Augment TrkA Signaling
Neurotrophins influence growth and survival of sympathetic and sensory neurons through activation of their receptors, Trk receptor tyrosine kinases. Previously, we identified Src homology 2-B (SH2-B) and APS, which are structurally similar adapter proteins, as substrates of Trk kinases. In the present study, we demonstrate that both SH2-B and APS exist in ce
