Abstract:
The recent identification of molecular components of the signal transduction pathway regulating activation of nuclear factor-kappaB (NF-kappaB) in response to cytokines such as tumor necrosis factor alpha and interleukin-1beta allows the evaluation of how other diverse stimuli impinge on the NF-kappaB activation pathway. These studies suggest a basis for specificity in activation of specific Rel-related family members and the genetic responses they promote.
