Many extremely preterm infants (born before 28 gestational weeks [GWs]) develop cognitive impairment in later life, although the underlying pathogenesis is not yet completely understood. Our examinations of the developing human neocortex confirmed that neuronal migration continues beyond 23 GWs, the gestational week at which extremely preterm infants have live births. We observed larger numbers...
Caspase-independent death mechanisms have been shown to execute apoptosis in many types of neuronal injury. P53 has been identified as a key regulator of neuronal cell death after acute injury such as DNA damage, ischemia, and excitotoxicity. Here, we demonstrate that p53 can induce neuronal cell death via a caspase-mediated process activated by apoptotic activating factor-1 (Apaf1) and via a d...
Neurodegeneration is a complex process that leads to irreversible neuronal damage and death in spinal cord injury (SCI) and various neurodegenerative diseases, which are serious, debilitating conditions. Despite exhaustive research, the cause of neuronal damage in these degenerative disorders is not completely understood. Elevation of cell surface α-enolase activates various inflammatory pathwa...
Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...
Caffeine-augmented electroconvulsive therapy has been introduced into medical practice without experimental confirmation that such seizure modification does not result in neuronal injury. In this report rats pretreated with caffeine prior to a series of nine electrically induced convulsions showed neuronal injury confined to hippocampal sectors and striatum. Electrically induced convulsions wit...
multiple sclerosis (ms) is a chronic inflammatory disease of the central nervous system characterized by widespread inflammation, focal demyelination and a variable degree of axonal and neuronal loss. ionic conductances regulate t cell activation as well as neuronal function and thus have been found to play a crucial role in ms pathogenesis. since present therapeutical approaches are only parti...
Neurofilament light chain (NfL) is an incredibly specific marker of neuronal injury that not for cause or location the damage. NfL increasingly considered as possible biomarker disease activity in neurological conditions. Several works reviewed utility different diseases. Nonetheless, a universal damage, which interpretation spaces beyond single disease. Because this, may benefit by also consid...
objective(s) high blood glucose induces molecular, cellular, morphological and behavioral changes in the brain. metabolic disturbances, contribute to the hippocampus injury and development of partial focal seizures. the aim of this study was to investigate the effects of infantile repeated hyperglycemia on neuronal density of hippocampal ca3region in newborn wistar male rats and its effect on c...
a common pathological process that occurred after brain injury is gliosis. gliosis involves the activation of glial cells to proliferate and become hypertrophic to occupy the injured brain areas. in order to form a defense system against the invasion of micro-organisms and cytotoxins into surrounding tissue, glial cells including astrocytes and microglia undergo reactive response to injury. neu...
