  • Tolerogenic antigen-presenting cells
    Publication number: 20040072348
    Abstract: It has been found that dendritic cells can be prepared which cannot mature. These cells can provide signal 1 to T cells but cannot provide co-stimulatory signal 2. T cells which are stimulated by the permanently immature dendritic cells therefore anergise, so the dendritic cells are tolerogenic rather than immunogenic. The cells are generally CD40−ve, CD80−ve and CD86−ve, and remain so when stimulated by inflammatory mediators such as lipopolysaccharide. The cells can be prepared conveniently by the culturing adherent embryonic stem cells in the presence of GM-CSF.
