BIOLOGIC CONTROL OF THE TUMOR-NECROSIS-FACTOR AND INTERLEUKIN-1 SIGNALING CASCADE

It is clear that activation of the proinflammatory cytokine cascade is both the cause and the consequence of renal injury, Recently, it has been appreciated that a rich network of signaling pathways contributes to modulation of tumor necrosis factor-alpha (TNF) and interleukin-1 (IL-1) bioactivity, both in vitro and in vivo. Insight into the checks and balances that intervene or temper endogenous cytokine effector me chanisms has arisen from an explosion of new information on the cell b iology of proinflammatory cytokines. Novel mechanisms of cytokine regu lation are currently being described and hold promise for therapeutic potential: soluble cytokine receptors, endogenous receptor antagonists , and anti-inflammatory cytokines such as IL-4, IL-10, and IL-13.
