A human IL-5 promoter/enhancer luciferase gene construct transfected into IL-5 -producing T cell clones was clearly transcribed after stimulation , indicating that the 515 base pair IL-5 gene segment upstream of the coding region was sufficient to respond to activating signals in human helper T cells .
