3) Transsphenoidal encephaloceles contain mature neuroglial cells with a varying degree of gliosis, in which astrocytes have divided and formed fibrillary networks called glial scar tissue. Although the cellular target of Pb is still elusive, exposure to Pb activates protein kinase C (PKC) in several types of cells, such as astrocytes and neuronal cells in the brain (Costa 1998; Markovac and Goldstein 1988).
