Abstract

Fos oncoprotein is an immediate early gene product and a marker of cell activation following a variety of insults. We have previously shown that a mechanical lesion to the hippocampus of adult mice induces a neuronal expression of the cytokines interleukin-1alpha (IL-1alpha) and tumor necrosis factor-alpha (TNF alpha) whereas a lesion to the striatum does not. The role of these inflammatory cytokines in the pathophysiology of central neurons is still unclear. The present work was undertaken to study a possible correlation between the central expression patterns of c-Fos on the one hand and IL-1alpha and TNF alpha on the other hand. We show that Fos is expressed in a majority of brain neurons after a unilateral lesion to the hippocampus whereas it is confined to the site of injury when applied to the striatum, as previously described for the expression of the cytokines.

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.
