Abstract/OtherAbstract:
This paper is an introduction to the papers by Hervey and Harris that describe their experimental use of parabiosis in rats and mice to search for circulating lipostatic signals. Beginning in 1959 with Hervey's foundational paper, they detected three parabiotic signals: the Hervey signal decreases food intake and fat mass in rats; the antilipogenic factor (ALF) decreased fat mass, but not food intake in rats; and the leptin-dependent signal in lean partners of ob/ob mice decreased fat mass, but not food intake. The known lipostatic signals, leptin and insulin, have been candidates for the Hervey and ALF signals, but insulin has been excluded and the evidence for leptin is inconclusive. The site of production of the three parabiotic signals and their molecular structure are not known and specific mechanisms of their lipostatic control are incompletely understood. Given their potential importance for understanding the physiology of lipostatic controls and for developing new therapies for obesity, Hervey and Harris make a strong argument for further research on the three parabiotic signals.
