Insulin-like immunoreactivity in human cerebrospinal-fluid is independent of insulin blood levels.

Abstract

Samples of cerebrospinal fluid were taken from 81 patients and investigated for insulin-like immunoreactivity by use of radioimmunoassay. The data suggest that IRI levels of Liquor cerebrospinalis are independent of blood insulin concentrations. It is supposed that nervous tissue is the source of IRI in the cerebrospinal fluid.
