Effective cancer vaccines need to target dendritic cells to stimulate both parts of the cellular immune system; the helper cell system where inflammation is stimulated at the tumor site; and the cytotoxic T-lymphocyte or CTL response where immune system cells are primed to recognise and kill specific cells.
Crohn's disease is characterized by a marked imbalance between T helper cell type 1- and T helper cell type 2-derived cytokine activity.
