Dendritic cells (DC) play an essential role in the induction of primary immune responses; however, very little information is available on cytokine production by DC. Here we determined the cytokine gene expression profile of two immortalized DC clones, CB1 and D2SC/1, both generated from mouse spleen but differing in their activation requirements. Among the(More)
We have developed a method to generate immortalized phagocytic and dendritic cell clones from various mouse tissues such as spleen, thymus, brain and bone marrow. The clones were phenotypically characterized and shown to retain the ability to respond to immune or inflammatory signals, e.g., IFN-gamma. Functional cytokine activity and nitric oxide production(More)
At the 38th Annual Meeting of the Society for Leukocyte Biology held in Oxford this year, the biology of dendritic cells (DCs) and macrophages was discussed. In particular, functional genomics approaches were presented to investigate transcriptional changes during microbe and phagocytes interactions. Here, we report functional genomics studies likely to be(More)
Toll-like receptors (TLRs) are the best characterized pattern recognition receptors. Individual TLRs recruit diverse combinations of adaptor proteins, triggering signal transduction pathways and leading to the activation of various transcription factors, including nuclear factor kappaB, activation protein 1 and interferon regulatory factors. Interleukin-2(More)
The VN-11 recombinant retroviruses, originally generated by co-transfection of the avian MH2 and AKRv viral genomes, were molecularly cloned from an infected mouse cell line named N11. The analysis of the proviral genome sequence from one of these recombinants showed a possible envAKR-mycMH2 fusion. Point mutations were also found in this envAKR-mycMH2(More)
Dendritic cells (DCs) are professional antigen presenting cells that hold the key to the induction of T-cell responses. Therefore, the use of DCs for immunotherapy to stimulate immune responses has recently raised a great deal of interest. Many clinical trials using DCs have been initiated to stimulate immune responses against tumors or infectious agents.(More)
Microarray platforms require analytical pipelines with modules for data pre-processing including data normalization, statistical analysis for identification of differentially expressed genes, cluster analysis, and functional annotation. We previously developed the Automated Microarray Data Analysis (AMDA, version 2.3.5) pipeline to process Affymetrix 3' IVT(More)
Myasthenia gravis (MG) is an autoimmune disease in which the thymus frequently presents follicular hyperplasia and signs of inflammation and T cells display a defect in suppressive regulation. Defects in a suppressive assay can indicate either the defective function of Treg cells or the resistance of Tconv cells to suppression by Treg cells. The aim of this(More)
Mycobacterium tuberculosis thrives within macrophages by residing in phagosomes and preventing them from maturing and fusing with lysosomes. A parallel transcriptional survey of intracellular mycobacteria and their host macrophages revealed signatures of heavy metal poisoning. In particular, mycobacterial genes encoding heavy metal efflux P-type ATPases(More)
