Abstract
The functional neuroanatomy of the immune system link to the CNS was investigated by assessing neuronal activity with Fos immunohistochemistry following systemic lipopolysaccharide (LPS) administration. Two hours after LPS robust Fos-like immunoreactivity (Fos-IR) was observed in several nuclear groups in the brain including the paraventricular and supraoptic nuclei of the hypothalamus, central nucleus of the amygdala, and nucleus of the solitary tract. A similar but diminished pattern of Fos-IR was present at 6 hours and was absent 24 hours after LPS administration. Investigation of the functional neuroanatomy of the acute phase reaction could prove to be critical in enhancing the ability of individuals to combat insults such as tissue damage and inflammation.
