Astroglial function of schizophrenic brain: a study using lobotomized brain

The neurodevelopmental hypothesis is now being recognized as one of the most useful hypothesis for schizophrenia, and by using it, abnormalities in protein associated with neuron growth or neuronal migration have been reported. From neuron-glia interrelations in the neural development, it is important to study the function of astroglia in the schizophrenic brain. In this study, we examined the neuropathological reaction of astroglia using lobotomized brains, and a significant decrease of astroglia after artificial histological damage was observed in schizophrenic brains. We speculated that this may be due to the latent vulnerability of the dynamic function of astroglia in schizophrenia. Astroglia plays a guidance role on migration and if astroglia has latent vulnerability, we speculate that younger neurons may not sufficiently migrate during development. In further investigation of the neurodevelopmental hypothesis of schizophrenia, it will be necessary to examine the function of astroglia.
