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.
