Serial sections stained for GFAP revealed robust astroglial hypertrophy and GFAP expression around the injury site but not within regions of immunological demyelination; astrocytes within regions of immunological demyelination did not display the intense GFAP staining typical of reactive astrocytes either at a distance from or immediately adjacent to the base of the lesion (Figure 4(b)).
Several researchers have reported the production of members of the neurotrophin family such as NGF, BDNF, and neurotrophin-3 in the cultured astroglial cell lines (Moretto et al., 1994; Oderfeld-Nowak et al., 1992).
Among the most studied neuronal cytoskeletal proteins in astrocytomas is neurofilament protein (NF).[64-66] Neurofilament-like immunoreactivities in astroglial tumors are unusually frequent, although published data differ considerably among studies.

The second is an astroglial vicious circle in which TNF-[alpha] stimulates astrocytes to release glutamate that cannot be efficiently taken up by their glutamate transporters, thus increasing more and more the extracellular glutamate concentrations.
These results agree with those found in astrocytes treated with hemin suggesting a critical role for astroglial GSH in the cellular defense against oxidative stress in the brain.
One of the anticonvulsive effects of levetiracetam could be mediated through suppression of astroglial activation by inflammatory mediators [8].
A majority of cases were diagnosed with astroglial tumors (57%) and nearly equal proportions had PNET (20%) or other histologic tumor types (23%).

Decreased levels of beta-amyloid plaque in response to EE have been highlighted also by Beauquis and coworkers who analyzed the astroglial changes in the hippocampus of transgenic animals [55].
