The Changes of Glial Fibrillary Acid Protein Level in the Different Brain Areas of Gerbils Under Development, Aging and Alpha-Keto Glutarate Effect

Abstract

There has been shown the change of level of astrocytes-specific glial fibrillary acid protein (GFAP) in different areas of the brain of laboratory gerbils at different stages of postnatal development, aging, and the effect of lphaketoglutarate.Studies have shown that the content of both soluble and filament forms of GFAP significantly increased during the first 30 days of postnatal development in all parts of the brain. After 30 days, the level of soluble forms of GFAP continued gradualy increase in all studied brain areas of gerbils during development and aging. Content of filament forms of GFAP in the gerbils brain after 90 days has a different tendency to change depending on the brain region. The long-term diet containing 2% alpha-ketoglutarate has been prevented overproduction of filament form of GFAP in the thalamus and hippocampus of older animals.
