Proneurotrophins, seizures, and neuronal apoptosis.
Neurons respond to numerous factors in their environment that influence their survival and function during development and in the mature brain. Among these factors, the neurotrophins have been shown to support neuronal survival and function, acting primarily through the Trk family of receptor tyrosine kinases. However, recent studies have established that the uncleaved neurotrophin precursors, ...
متن کاملInduction of proneurotrophins and activation of p75NTR-mediated apoptosis via neurotrophin receptor-interacting factor in hippocampal neurons after seizures.
Seizure-induced damage elicits a loss of hippocampal neurons mediated to a great extent by the p75 neurotrophin receptor (NTR). Proneurotrophins, which are potent apoptosis-inducing ligands for p75(NTR), were increased in the hippocampus, particularly in astrocytes, by pilocarpine-induced seizures; and infusion of anti-pro-NGF dramatically attenuated neuronal loss after seizures. The p75(NTR) i...
متن کامل[Interleukin-1ß, seizures and neuronal cell death].
Epilepsy is a neurological disorder affecting almost 1% of the world population. Experimental human and animal studies suggest that inflammation mediators, like cytokines, participate in the physiopathology of epilepsy. Interleukin-1beta (IL-1ß) could influence susceptibility for seizures, as well as neuronal death caused by seizures, although some findings are contradictory. This document revi...
متن کاملDecreased neuronal synchronization during experimental seizures.
Synchronization between CA1 pyramidal neurons was studied using dual-cell patch-clamp techniques simultaneous with an extracellular measurement of network activity. We explored various linear and nonlinear methods to detect weak synchronization in this network, using cross-correlation, mutual information in one and two dimensions, and phase correlation in both broad and narrow band. The linear ...
متن کاملUnification of neuronal spikes, seizures, and spreading depression.
The pathological phenomena of seizures and spreading depression have long been considered separate physiological events in the brain. By incorporating conservation of particles and charge, and accounting for the energy required to restore ionic gradients, we extend the classic Hodgkin-Huxley formalism to uncover a unification of neuronal membrane dynamics. By examining the dynamics as a functio...
