FEVER ROLE OF PYROGENS AND CRYOGENICS PDF

The role of proinflammatory cytokines in the pathogenesis of fever has been discovered at febrile responses to LPS, showing that TNF has cryogenic properties in this model [37]. .. Fever: the role of pyrogens and cryogens. not affect mTNF-c-induced fever. 6 These data indicate that endogenous TNF-a is probably a pyrogen and that previous results suggesting cryogenic actions of. (i.e. endogenous pyrogens), including interleukin (IL)-1β, IL-6 and others. the evidence that specific cytokines, IL-1 and IL-6, play a role in fever. .. It is possible that some of these may exert antipyretic or cryogenic activity during infection.
