The first two fractions were CD11c1 DCs, comprised of a major CD1a1/CD11c1 population (fraction 1), and a minor CD1a2/CD11c1 component (fraction 2). Both CD11c1 fractions displayed a monocyte-like morphology, endocytosed FITC-dextran, expressed CD45RO and myeloid markers such as CD13 and CD33, and possessed the receptor for GM-CSF. The third fraction was comprised of CD1a2/CD11c2 DCs (fraction 3) and resembled plasmacytoid T cells. These did not uptake FITC-dextran, were negative for myeloid markers (CD13/CD33), Downloaded from and expressed CD45RA and a high level of IL-3Ra, but not GM-CSF receptors. After culture with IL-3, fraction 3 acquired the characteristics of mature DCs; however, the expression of CD62L (lymph node-homing molecules) remained unchanged, indi- cating that fraction 3 can be a precursor pool for previously described plasmacytoid T cells in lymphoid organs. Strikingly, the CD1a1/CD11c1 DCs (fraction 1) quickly acquired LC characteristics when cultured in the presence of GM-CSF 1 IL-4 1 TGF-b1.

Furthermore, CD141 monocytes only expressed E-cadherin, but lacked the other LC markers after culture in these cytokines.

    Regulation of Macrophage Development and Function in Peripheral Tissues

    REVIEWS Regulation of macrophage development and function in peripheral tissues Yonit Lavin, Arthur Mortha, Adeeb Rahman and Miriam Merad Abstract | Macrophages are immune cells of haematopoietic origin that provide crucial innate immune defence and have tissue-specific functions in the regulation and maintenance of organ homeostasis. Recent studies of macrophage ontogeny, as well as transcriptional and epigenetic identity, have started to reveal the decisive role of the tissue stroma in the regulation of macrophage function. These findings suggest that most macrophages seed the tissues during embryonic development and functionally specialize in response to cytokines and metabolites that are released by the stroma and drive the expression of unique transcription factors. In this Review, we discuss how recent insights into macrophage ontogeny and macrophage–stroma interactions contribute to our understanding of the crosstalk that shapes macrophage function and the maintenance of organ integrity.

Wognum1 1 STEMCELL Technologies Inc., Vancouver, BC, Canada 2 Terry Fox Laboratory, BC Cancer Agency, Vancouver, BC, Canada Introduction The use of T cells for cancer immunotherapy and other therapeutic applications relies on the isolation of T cells from peripheral blood and their subsequent activation and expansion in culture. T cells can also be generated from hematopoietic stem and/or progenitor cells (HSPCs) in cord blood (CB) or bone marrow (BM). This approach not only offers a renewable source of T cells, but also provides a model system to study disease mechanisms or validate new drugs that affect T cell development and/or function. Differentiation of HSPCs to T cells typically requires co-culture with stromal cell lines that have been engineered to express a Notch-ligand. In such cultures, CD34+CD38-/lo HSPCs develop into CD7+CD5+ pro-T cells that further differentiate to T lineage-committed progenitor cells (pre-T cells) characterized by the expression of CD1a. CD7+CD1a+ pre-T cells can then differentiate to express CD4 and become CD4 immature single-positive (CD4ISP) cells. CD4ISP cells give rise to CD4+CD8+ double positive (DP) cells. These finally mature into CD4 and CD8 single-positive (SP) CD3+TCRαβ+ T cells. Here we describe a serum-free culture method that recapitulates these differentiation steps in the absence of stromal cells and generates large numbers of functional T lineage cells from a limited number of purified CD34+ CB cells.

However, only a few similar studies have been carried out to date in a naturally occurring human prion disease. To better characterize the transcriptional cascades associated with sporadic Creutzfeldt-Jakob disease (sCJD), the most common human prion disease, we investigated the global gene expression profile in samples from the frontal cortex of 10 patients with sCJD and 10 non-neurological controls by microarray analysis. The comparison identified 333 highly differentially expressed genes (hDEGs) in sCJD. Functional enrichment Gene Ontology analysis revealed that hDEGs were mainly associated with synaptic transmission, including GABA (q value = 0.049) and glutamate (q value = 0.005) signaling, and the immune/ inflammatory response. Furthermore, the analysis of cellular components performed on hDEGs showed a compromised regu- lation of vesicle-mediated transport with mainly up-regulated genes related to the endosome (q value = 0.01), lysosome (q value = 0.04), and extracellular exosome (q value < 0.01). A targeted analysis of the retromer core component VPS35 (vacuolar protein sorting-associated protein 35) showed a down-regulation of gene expression (p value= 0.006) and reduced brain protein levels (p value= 0.002).

    6.4: HSV enhances HIV-1 transmission by LCs Chapter 6.4 Herpes simplex virus enhances HIV-1 transmission by Langerhans cells. Lot de Witte*, Marein A.W.P. de Jong*, Yvette van Kooyk and Teunis B.H. Geijtenbeek. Genital herpes is a risk factor to acquire HIV-1 infection by sexual contact, by increasing both infectivity of an infected person and susceptibility to acquire HIV-1. Here we have investigated the mechanisms that underlie the increased susceptibility to HIV-1 when people have genital herpes. Under steady state conditions, LCs capture HIV-1 through interaction with the C-type lectin Langerin, resulting in viral clearance and protection against HIV-1. During primary genital herpes or recurrent infections, HSV infects epithelial cells and encounters LCs in the mucosal epithelium. We set out to investigate the function of HSV-infected LCs and subepithelial DCs during HIV-1 transmission. We demonstrate that HSV interacts with soluble and cellular Langerin and that infection of LCs decreases expression of this receptor. Notably, LC infection with both HSV-1 and HSV-2 enhances HIV-1 transmission, suggesting an important role for LCs during HIV-1 transmission in the HSV-infected individual. Furthermore our data indicate that HSV infection of DCs and LCs has different outcomes for HIV-1 transmission, and our results suggest that DC-SIGN and Langerin are involved. Future research is needed to confirm the differential role of Langerin and DC-SIGN during HIV-1 transmission in conditions of genital herpes.

Introduction Genital herpes is a common infection, which is mainly caused by herpes simplex virus type-2 (HSV-2), although an increasing percentage of the genital herpes is caused by HSV-141.

    CD Markers Are Routinely Used for the Immunophenotyping of Cells

    ptglab.com 1 CD MARKER ANTIBODIES www.ptglab.com Introduction The cluster of differentiation (abbreviated as CD) is a protocol used for the identification and investigation of cell surface molecules. So-called CD markers are routinely used for the immunophenotyping of cells. Despite this use, they are not limited to roles in the immune system and perform a variety of roles in cell differentiation, adhesion, migration, blood clotting, gamete fertilization, amino acid transport and apoptosis, among many others. As such, Proteintech’s mini catalog featuring its antibodies targeting CD markers is applicable to a wide range of research disciplines. PRODUCT FOCUS PECAM1 Platelet endothelial cell adhesion of blood vessels – making up a large portion molecule-1 (PECAM1), also known as cluster of its intracellular junctions. PECAM-1 is also CD Number of differentiation 31 (CD31), is a member of present on the surface of hematopoietic the immunoglobulin gene superfamily of cell cells and immune cells including platelets, CD31 adhesion molecules. It is highly expressed monocytes, neutrophils, natural killer cells, on the surface of the endothelium – the thin megakaryocytes and some types of T-cell.
