Neurons may remain immature concerning GABAergic neurotransmission in Rett syndrome Abnormal expression of cation chloride cotransporters has been found in the cerebrospinal fluid of patients with Rett syndrome (RTT). This finding suggest an abnormal GABaergic transmission and neuronal maturation. According to these results, neurons of RTT patients could remain “immature” regarding GABA excitability, as it […]

Interneuronas, GABA y enfermedades neuropediátricas
What do you know about interneurons? Which processes do you think they regulate? How could dysfunction in interneurons and abnormal gabaergic transmission contribute to the pathophysiology of some neuropaediatric disorders? Interneurons were classically described as short-axon neurons with connections between “input” and “output” principal cells and were recognized for their role in modulating excitability via […]
Neurotransmisión colinérgica y cerebro en desarrollo
What do you know about acetylcholine? What about its role in the developing brain? Are there diseases of the central nervous system due to abnormal cholinergic transmission in paediatrics? Our current knowledge about disorders of neurotransmission in children is focused on transmitters such as dopamine, serotonin or GABA. By contrast little is known about the […]
El “tráfico” mitocondrial se relaciona con la plasticidad axonal
LKB1, NUAK1 and SNPH are proteins related to those proceses Courchet, J., et al. Terminal axon branching is regulated by LKB1-NUAK1 kinase pathway via presynaptic mitochondrial capture. Cell. 2013 (153):1510-1525 Sun, T., et al. Motile Axonal Mitochondria Contribute to the Variability of Presynaptic Strength. Cell Reports. August 2013 (4):1-7. Axon formation, presynaptic strength and […]
Serotonina y arquitectura del córtex cerebral
The neurotransmitters sculpt the brain Serotonin is an abundant neurotransmitter in the brain. During development, serotonin regulates processes such as neuronal migration and dendrite differentiation through some particular 5HT receptors. Abnormal serotoninergic neurotransmission during early periods of life may disrupt the construction of cortical circuits and contribute to neurologic and neuropsychiatric disorders. The human […]
