NKCC1-Mediated GABAergic Signaling Promotes Postnatal Cell Death in Neocortical Cajal-Retzius Cells.
2016
During early development, a substantial proportion of central neurons undergoes programmed cell death. This activity-dependent process is essential for the proper structural and functional development of the brain. To uncover cell type-specific differences in the regulation of neuronal survival versus apoptosis, we studied activity-regulated cell death in Cajal-Retzius neurons (CRNs) and the overall neuronal population in the developing mouse cerebral cortex. CRNs in the upper neocortical layer represent an early-born neuronal population, which is important for cortical development and largely disappears by apoptosis during neonatal stages. In contrast to the overall neuronal population, ac…
Ultrastructural changes in the Interstitials Cells of Cajal and gastric dysrhythmias in mice lacking full-length dystrophin (mdx mice)
2004
At least two populations of c-kit positive interstitial cells of Cajal (ICC) lie in the gastric wall, one located at the myenteric plexus level has a pace-making function and the other located intramuscularly is intermediary in the neurotransmission and regenerates the slow waves. Both of these ICC sub-types express full-length dystrophin. Mdx mice, an animal model lacking in full-length dystrophin and used to study Duchenne muscular dystrophy (DMD), show gastric dismotilities. The aim of the present study was to verify in mdx mice whether: (i) gastric ICC undergo morphological changes, through immunohistochemical and ultrastructural analyses; and (ii) there are alterations in the electrica…
