Expression of Nerve Growth Factor, Brain-Derived Neurotrophic Factor and Neurotrophin-3 mRNAs in Human Cortical Xenografts
نویسندگان
چکیده
Trophic factors play an important role in the development of neurons and glia. In order to study the involvement of neurotrophins in human cortical development, human fetal parietal cortical tissue, obtained after early elective abortions, was transplanted to cortical cavities in immunosuppressed rats. Using in situ hybridization it was demonstrated that nerve growth factor, brain-derived neurotrophic factor and neurotrophin-3 mRNAs are expressed in developing human cortical xenografts. We conclude that neurotrophins may play a role in human cortical development and rat-derived astroglial cells could be involved in establishing reciprocal "permissive sites".

P-52: Brain-Derived Neurotrophic Factor Promotes The Development of Human Ovarian Early Follicles during Growth In Vitro
Background Cryopreservation of ovarian cortex is increasingly used to preserve fertility before cancer therapy. Recently, studies show that Brain-derived neurotrophic factor (BDNF) may be involved in oocyte maturation. Brain-derived neurotrophic factor (BDNF) is member of neurotrophin family that has anti-apoptotic effects on nervous system. Recent researches show that it also plays key role in...
متن کاملNeurotrophins induce short-term and long-term changes of cortical neurotrophin expression.
Neuronal activity, hormones, transmitters, physical exercise and enrichment influence cortical neurotrophin expression. Neurotrophins then elicit structural and physiological changes, and regulate gene expression. This prompted the hypothesis that neurotrophins themselves are involved in regulating neurotrophin expression. Here we investigated the mRNA expression level of brain-derived neurotro...

متن کاملNeurotrophins and their receptors in rat peripheral trigeminal system during maxillary nerve growth
We examined the expression of the neurotrophins (NTFs) and their receptor mRNAs in the rat trigeminal ganglion and the first branchial arch before and at the time of maxillary nerve growth. The maxillary nerve appears first at embryonic day (E)10 and reaches the epithelium of the first branchial arch at E12, as revealed by anti-L1 immunohistochemistry. In situ hybridization demonstrates, that a...

Post-traumatic stress disorder (PTSD) is a syndrome causing from a severe traumatic happening that leads to threatened death or injury. PTSD is associated with changes in limbic, hippocampal, and prefrontal cortical region function due to changes in synaptogenesis, dendritic modifying, and neurogenesis. Changes in neuron in PTSD patients result from pathophysiological disturbances in inflammato...
