neuroglia

 [noo͡-rog´le-ah]
the supporting structure of nervous tissue, consisting, in the central nervous system, of astrocytes, oligodendrocytes, and microglia; called also glia. adj., adj neurog´lial.

neu·rog·li·a

(nū-rog'lē-ă), This word is grammatically singular. Avoid the mispronunciation neurogli'a.
Nonneuronal cellular elements of the central and peripheral nervous system; formerly believed to be merely supporting cells but now thought to have important metabolic functions, in that they are invariably interposed between neurons and the blood vessels supplying the nervous system. In central nervous tissue they include oligodendroglia cells, astrocytes, ependymal cells, and microglia cells. The satellite cells of ganglia and the neurolemmal or Schwann cells around peripheral nerve fibers can be interpreted as the oligodendroglia cells of the peripheral nervous system.

neuroglia

/neu·rog·lia/ (ndbobr-rog´le-ah) the supporting structure of nervous tissue, consisting of a fine web of tissue enclosing neuroglial cells, which are of three types: astrocytes, oligodendrocytes, and microcytes.neurog´lial

neuroglia

(no͝o-rŏg′lē-ə, nyo͝o-, no͝or′ə-glē′ə, -glī′-, nyo͝or′-)
n.
The supportive tissue of the nervous system, including the network of branched cells in the central nervous system (astrocytes, microglia, and oligodendrocytes) and the supporting cells of the peripheral nervous system (Schwann cells and satellite cells). Also called glia.

neu·rog′li·al adj.

neuroglia

[noo͡rog′lē·ə]
Etymology: Gk, neuron + glia, glue
the supporting or nonneuronal tissue cells of the central and peripheral nervous system. They perform the less specialized functions of the nerve network. Kinds of neuroglia include astrocytes, oligodendroglia, and microglia. Compare neuron. neuroglial, adj.

neu·rog·li·a

(nūr-og'lē-ă) [TA]
Nonneuronal cellular elements of the central and peripheral nervous system; thought to have important metabolic functions. In central nervous tissue they include oligodendroglia cells, astrocytes, ependymal cells, and microglia cells.
Synonym(s): glia, reticulum (2) .
[G. neuron, tendon, nerve, + glia, glue]

neuroglia

The network of branched cells and fibres that forms the supporting connective tissue of the central nervous system. Certain brain tumours arise from neuroglial cells.

During our study, we assessed gene expression in isolated neuroglia cells exposed to Rhodiola extract or one of its active constituents (salidroside, triandrin, and tyrosol) by analyzing mRNA arrays.
In this study, we tested the effects of Rhodiola SHR-5 extract and three isolated compounds (salidroside, triandrin, and tyrosol) on the gene expression profile of isolated human neuroglia cells using an n-RNA array.

After treatment the human neuroglia cell line T98G was centrifuged to discard floating cells and cellular debris and the total protein content was determined by Bradford analysis using bovine serum albumin as a standard.
Human neuroglia cells were grown to 75% confluence.
We demonstrated that validated adaptogens significantly stimulate NPY release from human neuroglia cells (Table 2).
We further validated the central role of NPY in experiments in which pre-treatment of human neuroglia cells with silencing RNA NPY-siRNA and HSF1-siRNA resulted in the significant suppression of ADAPT-232-induced NPY and Hsp72 release.
This was achieved by measuring the release of NPY and Hsp72 from neuroglia cells in response to treatment with test compounds including selected validated adaptogens, partly validated adaptogens, claimed but negligibly validated adaptogens and other plant extracts affecting neuroendocrine and immune systems which have never been considered as adaptogens using high throughput ELISA techniques.
To determine whether the results we obtained using the transformed human neuroglia cells in which the release of NPY and/or Hsp72 is relevant for physiologically normal cells and evaluation of effects of adaptogens, we repeated the experiments using a system more closely related to the human system; non-transformed human neurons.
