Abnormalities consisting of either branching or spine defects are found in many diseases of genetic origin, such as Down's, Fragile X, and Rett syndromes, and in nongenetic disorders associated with mental retardation. Disruption of dendrite development is the most consistent anatomical finding in mental retardation (reviewed.
In some areas of the brain, such as the hippocampus, process growth and remodeling continues throughout adult life and is profoundly affected by electrical activity. These processes begin to form during embryogenesis but continue to extend and branch profusely long after neuronal migration is complete, contributing significantly to postnatal brain growth. File Information: Name: Paragon NTFS 15 File Size: 24 MB Publisher:? File Type: Dmg File Release Date: Languages: English System Requirements: Dendrites are key morphological features of neurons that define their physiological properties and connectivity. Thus, the same signaling pathway controls both neuronal migration and dendrite maturation. Addition of Reelin interfering antibodies, receptor antagonists, and Dab1 phosphorylation inhibitors prevented dendrite outgrowth from normal neurons, whereas addition of recombinant Reelin rescued the deficit in reeler cultures. We found that dendrite complexity is severely reduced in homozygous mice deficient in Reelin signaling both in vivo and in vitro, and it is also reduced in heterozygous mice in the absence of cellular ectopia. Here we examined dendrite development in the hippocampus of normal and mutant mice and in dissociated cultures. It is unclear whether these defects are due primarily to cellular ectopia or the absence of Reelin. In addition to cellular disorganization, dendrite abnormalities are present in the brain of reeler mice lacking Reelin. Reelin is a secreted glycoprotein that regulates neuronal positioning in cortical brain structures through the VLDLR and ApoER2 receptors and the adaptor protein Dab1.
