Up-regulation of lipocortin-1 and its mRNA in reactive astrocytes in kainate-lesioned rat cerebellum
1994
Abstract We have used a combined molecular and immunocytochemical approach to examine the expression of lipocortin-1 (LC-1) in kainate-lesioned rat cerebellum. Using immunocytochemistry, Western and Northern blotting, we have shown upregulation of LC-1 mRNA and expression of LC-1 localised specifically to reactive astrocytes. These studies suggest that reactive astrocytes are a major synthetic compartment for the expression of LC-1. The well-reported immuno-suppressive effects of lipocortin(s), suggests that reactive astrocytes could serve to negatively modulate inflammatory reactions in the central nervous system.
