Hydrocortisone Attenuates the Development of Malformations of the Polymicrogyria Spectrum
Most of the malformations of the polymicrogyria spectrum are caused by destructive lesions of the neocortex during the third trimester of pregnancy, triggered by hypoxic–ischemic, hemorrhagic or infectious events, with neuroinflammation as a common pathophysiological mechanism. Our study investigated hydrocortisone treatment in attenuating inflammation, malformations development and seizures predisposition in mice subjected to neonatal transcranial freeze lesion. Our results show attenuation of malformation and predisposition to febrile seizures, with concomitant reduction of macrophages/microglia after neonatal freeze lesion, polarizing them towards an anti-inflammatory profile. Thus, we have identified a promising treatment to minimize the development of cortical developmental malformations.
期刊介绍：
International Journal of Developmental Neuroscience publishes original research articles and critical review papers on all fundamental and clinical aspects of nervous system development, renewal and regeneration, as well as on the effects of genetic and environmental perturbations of brain development and homeostasis leading to neurodevelopmental disorders and neurological conditions. Studies describing the involvement of stem cells in nervous system maintenance and disease (including brain tumours), stem cell-based approaches for the investigation of neurodegenerative diseases, roles of neuroinflammation in development and disease, and neuroevolution are also encouraged. Investigations using molecular, cellular, physiological, genetic and epigenetic approaches in model systems ranging from simple invertebrates to human iPSC-based 2D and 3D models are encouraged, as are studies using experimental models that provide behavioural or evolutionary insights. The journal also publishes Special Issues dealing with topics at the cutting edge of research edited by Guest Editors appointed by the Editor in Chief. A major aim of the journal is to facilitate the transfer of fundamental studies of nervous system development, maintenance, and disease to clinical applications. The journal thus intends to disseminate valuable information for both biologists and physicians. International Journal of Developmental Neuroscience is owned and supported by The International Society for Developmental Neuroscience (ISDN), an organization of scientists interested in advancing developmental neuroscience research in the broadest sense.
