Gene Set: GSE8835_CD4_VS_CD8_TCELL_DN

Standard name GSE8835_CD4_VS_CD8_TCELL_DN
Systematic name M6255
Brief description Genes down-regulated in T cells: CD4 [GeneID=920] versus CD8.
Full description or abstract To examine the impact of tumors on the immune system, we compared global gene expression profiles of peripheral blood T cells from previously untreated patients with B cell chronic lymphocytic leukemia (CLL) with those from age-matched healthy donors. Although the cells analyzed were not part of the malignant clone, analysis revealed differentially expressed genes, mainly involved in cell differentiation in CD4 cells and defects in cytoskeleton formation, vesicle trafficking, and cytotoxicity in CD8 cells of the CLL patients. In coculture experiments using CLL cells and T cells from healthy allogeneic donors, similar defects developed in both CD4 and CD8 cells. These changes were induced only with direct contact and were not cytokine mediated. Identification of the specific pathways perturbed in the T cells of cancer-bearing patients will allow us to assess steps to repair these defects, which will likely be required to enhance antitumor immunity. Gene expression profiling was performed to determine whether CLL cells induce changes in T cells in patients with CLL.
