Role of PKD2 in TCR-induced transcriptional reprogramming of naïve T cells


ABSTRACT: Comparison of transcriptional profile of TCR stimulated P14-TCR wild-type and P14-PKD2 null murine lymph node cells Lymph node cells from 3 biological replicates (3 wild-type and 3 PKD2 null mice) were isolated and left unstimulated or stimulated for 4 hours with antigenic peptide (gp33-41) prior to RNA extraction and hybridization to Affymetrix microarray.

PKD (protein kinase D) 2 is a serine/threonine kinase activated by diacylglycerol in response to engagement of antigen receptors in lymphocytes. To explore PKD2 regulation and function in TCR (T-cell antigen receptor) signal transduction we expressed TCR complexes with fixed affinity for self antigens in the T-cells of PKD2-null mice or mice deficient in PKD2 catalytic activity. We also developed a single cell assay to quantify PKD2 activation as T-cells respond to developmental stimuli or engag  ...[more]
