The cellular mechanism governing the diminished proliferative response of neonatal T lymphocytes to anti-CD2 may therefore be due to decreased NF kappa B induction , reduced IL-2 mRNA expression and deficient IL-2 production .
 protein: NF kappa B; protein: IL-2; RNA: IL-2 mRNA; protein: IL-2; protein: anti-CD2; cell type: neonatal T lymphocytes
