Description:
Plasma obtained from human subjects after exercise and injected intraperitoneally into rats elevated rat rectal temperature and depressed plasma iron and zinc concentrations. The pyrogenic component was heat-denaturable and had an apparent molecular weight of 14,000 daltons. Human mononuclear leukocytes obtained after exercise and incubated in vitro released a factor into the medium that also elevated body temperature in rats and reduced trace metal concentrations. These results suggest that endogenous pyrogen, a protein mediator of fever and trace metal metabolism during infection, is released during exercise.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cannon, J G -- Kluger, M J -- AI 13878/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1983 May 6;220(4597):617-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836306" target="_blank"〉PubMed〈/a〉
