Article Abstract
Glial fibrillary acidic protein (GFAP), a biochemical marker of astrocytes and glial reaction, was quantified by immunoblotting in different brain areas from 33 non-demented patients with a Mini Mental State Examination score above 26 and aged from 12 to 98 years. An increase of GFAP with age was first found in the hippocampus and then in the entorhinal cortex. In both regions, GFAP amounts were correlated with age (r = 0.768). In the isocortex, the increase of GFAP as a function of age was also significant (r = 0.672), but less than for the hippocampal region. GFAP levels increased dramatically after the age of 65 years, and more especially in the hippocampal formation. This glial reaction was observed in aged controls that do not show cognitive impairment and the neuropathological hallmarks of Alzheimer's disease.

Ischemic stroke (IS) often causes fearful sequela, even death. Curcumin was beneficial to IS, but its underlying molecular mechanism is unclear. Mice were subjected to middle cerebral artery occlusion (MCAO) surgery, and BV-2 cells were treated with oxygen-glucose deprivation/reoxygenation (OGD/R) induction to establish IS models in vivo and in vitro.

Aims: Communication within glial cells acts as a pivotal intermediary factor in modulating neuroimmune pathology. Meanwhile, an increasing awareness has emerged regarding the detrimental role of glial cells and neuroinflammation in morphine tolerance (MT). This study investigated the influence of crosstalk between astrocyte and microglia on the evolution of morphine tolerance.

Acute peripheral vestibular dysfunction is associated with a variety of postural and balance disturbances. Vestibular rehabilitation training (VRT) is widely acknowledged as an effective intervention for promoting vestibular compensation. Nevertheless, the broader implementation of early VRT is hindered by an incomplete understanding of its neurobiological mechanisms.

Cognitive impairment is a core feature of neurodevelopmental (schizophrenia) and aging-associated (mild cognitive impairment and Alzheimer's dementia) neurodegenerative diseases. Limited efficacy of current pharmacological treatments warrants further search for new targets for nootropic interventions. The breakdown of myelin, a phospholipids axonal sheath that protects the conduction of nerve impulse between neurons, was proposed as a neuropathological abnormality that precedes and promotes the deposition of amyloid-β in neuritic plaques.

Unlabelled: Background Monosodium glutamate (MSG) in its anionic form, glutamate, is one of the main excitatory amino acids. Excess of this neurotransmitter may lead to excitotoxicity affecting neurons and astrocytes responsible for glutamate metabolism in different brain areas of animals. The aim of the study was to investigate the immunoreactivity of glial fibrillary acidic protein (GFAP) and S100β protein in the caudate nucleus of rats under the condition of elevated glutamate levels.
