Differential regulation of interleukin‐12 p40 and p35 induction via Erk mitogen‐activated protein kinase‐dependent and ‐independent mechanisms and the implications for bioactive IL‐12 and IL‐23 responses

Abstract
Bioactive interleukin (IL)-12 is a 70 000-molecular weight (MW) heterodimeric cytokine comprising p40 and p35 chains. However, p40 can also form homodimers that antagonize bioactive IL-12 or heterodi...
