Serum proteins are known to extravasate into the brain parenchyma in senile and presenile dementia (Glenner: Hum. Pathol. 16:433-435, 1986; Wisniewski and Kozlowski: Ann. NY Acad. Sci. 396:119-129, 1982). We have recently demonstrated that human serum Cohn fraction IV (alpha-globulin enriched) inhibits ligand binding at putative dopamine and serotonin2 receptors labeled by [3H]spiroperidol in human brain (Andorn, Pappolla, Fox, Klemens, and Martello: Proc. Natl. Acad. Sci. USA 83:4572-4575, 1986). We now demonstrate that serum proteins can be identified in the neuropil and in neuronal cell bodies in normal aged brain, that alpha-globulin-enriched fractions inhibit ligand binding at alpha 2-adrenergic and muscarinic binding sites in human brain as well, and that serum proteins can be identified within neuronal cytoplasm and axons.
