Introduction until quite recently, the prevailing view regarding the biology and pathology of astrocytes among those studying clinical disorders and structural lesions of the central nervous system (cns) was most likely to be that (1) astrocytes are supportive glial cell components in neural tissue and (2) reactive astrogliosis is a reliable and sensitive marker of diseased tissue.

Astrocytes regulate fundamentally important functions to maintain central nervous system (cns) homeostasis altered astrocytic function is now recognized as a primary contributing factor to an increasing number of neurological diseases in this review, we provide an overview of our rapidly . Cells of the central nervous system there are various cells which act as the major unit to help in the function of the cns properly out of which neurons and glia are the major ones. One function of an astrocyte is to support cells that make up the blood-brain barrier, which keeps many toxins out of the brain astrocytes also help regulate the balance of ions outside of the cells, help nourish nerve cells and help the central nervous system heal after injury astrocytes also . In the central nervous system, ng2-glia represent a neural cell population that is distinct from neurons, astrocytes, and oligodendrocytes while in the past the main role ascribed to these cells was that of progenitors for oligodendrocytes, in the last years it has become more obvious that they have further functions in the brain.

Overview of neuron structure and function glia of the central nervous system astrocytes extend their feet (projections) onto the cell bodies of neurons, while . Astrocytes are a special kind of stellate-shaped brain cells that are found throughout the central nervous system and that play a supportive role for neurons for a long time, astrocytes were thought of as merely providing “assistance” for neuron function and survival.

Astrocytes have recently been recognized as a crucial player at the synapse in the central nervous system (cns) as part of the tripartite synapse, astrocytes can detect and respond to neuronal activity, influencing the formation and plasticity of the synapse during development and into adulthood (araque & perea, 2004 yang et al .
