Maturation of dendritic cell precursors into IL12-producing DCs by J-LEAPS immunogens

Cell Immunol. 2010;262(1):1-5. doi: 10.1016/j.cellimm.2010.01.003. Epub 2010 Feb 1.


LEAPS (ligand epitope antigen presentation system) vaccines consist of a peptide containing a major histocompatibility antigen binding peptide conjugated to an immune cell binding ligand (ICBL) such as the 'J' peptide from beta-2-microglobulin. Treatment of monocytes, monocytes plus GMCSF, or monocytes plus GMCSF and IL4 with JgD (containing a peptide from gD of herpes simplex virus type 1) or JH (with a peptide from HIV p17 gag protein) was sufficient to promote their maturation into Interleukin 12 producing dendritic cells. JgD-dendritic cells supported allotypic activation of T cells to produce Th1-related cytokines.
