nature of the Endogenous Pyrogen ep induced by influenza viruses lack of correlation between ep levels and content of the known Pyrogenic cytokines interleukin 1 interleukin 6 and tumour necrosis factor
Journal of General Virology, 1991Co-Authors: Kenneth J Jakeman, Chris Bird, Robin Thorpe, H Smith, Clive SweetAbstract:Fever in influenza results from the release of Endogenous Pyrogen (EP) following virus-phagocyte interaction and its level correlates with the differing virulence of virus strains. However, the different levels of fever produced in ferrets by intracardial inoculation of EP obtained from the interaction of different virus strains with ferret or human phagocytes did not correlate with the levels of interleukin 1 (IL-1), IL-6 or tumour necrosis factor in the same samples as assayed by conventional in vitro methods. Hence, the EP produced by influenza virus appears to be different to these cytokines.

ciliary neurotrophic factor is an Endogenous Pyrogen
Proceedings of the National Academy of Sciences of the United States of America, 1993Co-Authors: Leland Shapiro, Xixia Zhang, Randall G Rupp, Sheldo M WolffAbstract:Abstract Fever is initiated by the action of polypeptide cytokines called Endogenous Pyrogens, which are produced by the host during inflammation, trauma, or infection and which elevate the thermoregulatory set point in the hypothalamus. Ciliary neurotrophic factor (CNTF) supports the differentiation and survival of central and peripheral neurons. We describe the activity of CNTF as intrinsically Pyrogenic in the rabbit. CNTF induced a monophasic fever which rose rapidly (within the first 12 min) following intravenous injection; CNTF fever was blocked by pretreatment with indomethacin. The fever induced by CNTF was not due to contaminating endotoxins. Increasing doses of CNTF resulted in prolongation of the fever, suggesting the subsequent induction of additional Endogenous Pyrogenic activity. After passive transfer of plasma obtained during CNTF-induced fever, Endogenous Pyrogen activity was not present in the circulation; CNTF also did not induce the Endogenous Pyrogens interleukin 1, tumor necrosis factor, or interleukin 6 in vitro. Nevertheless, a second Endogenous Pyrogen may originate within the central nervous system following the systemic injection of CNTF. Of the four Endogenous Pyrogens described to date (interleukin 1, tumor necrosis factor, interferon, and interleukin 6), CNTF, like interleukin 6, utilizes the cell-surface gp 130 signal-transduction apparatus.
