He worked on the mechanism of recovery from pneumonia and was noted for early work on surface phagocytosis, research into the pathogenesis of fever, and endogenous pyrogen ( now known as interleukin-1 ).
2.
However, in contrast to these two endogenous pyrogens, the fever induced by MIP-1 is not inhibited by the cyclooxygenase inhibitor ibuprofen and CCL3 may participate in the febrile response that is not mediated through prostaglandin synthesis and clinically cannot be ablated by cyclooxygenase.

Bartfai s group showed IL-1, then called the endogenous pyrogen, occurs and can be released from the adrenal medulla and brain and demonstrated that the endogenous pyrogen can control body temperature by acting at IL-1 receptors and hyperpolarizing hypothalamic gabaergic interneurons that control thermogenesis in brown adipose tissue ( BAT ), and thus core body temperature and the fever response .,

IL-1? is also known as fibroblast-activating factor ( FAF ), lymphocyte-activating factor ( LAF ), B-cell-activating factor ( BAF ), leukocyte endogenous mediator ( LEM ), epidermal cell-derived thymocyte-activating factor ( ETAF ), serum amyloid A inducer or hepatocyte-stimulating factor ( HSP ), catabolin, hemopoetin-1 ( H-1 ), endogenous pyrogen ( EP ), and proteolysis-inducing factor ( PIF ).
