Monocyte-derived dendritic cells (Mo-DCs) were generated from peripheral blood monocytes of 12 healthy volunteers (hMo-DCs) and 11 patients (pMo-DCs) with malignancies by culture for 7 days with granulocyte-macrophage colony-stimulating factor and interleukin-4. In this study, we focused on the cytogram pattern by FACS analysis. A gate (R1) was set up by which more than 95% of hMo-DCs were cont...
INTRODUCTION Dendritic cells (DCs) are the most efficient antigen presenting cells, which are considered a central component of the immune system for their extraordinary capacity to initiate and modulate the immune responses elicited upon recognition of infectious agents. This has made them a major focus of interest in the conception of immunotherapeutic vaccine strategies. AIM OF THE STUDY T...
Activation of the lipid-regulated nuclear receptor peroxisome proliferator-activated receptor gamma (PPARgamma) modifies the immunophenotype of monocyte-derived dendritic cells (DCs). However it has not been analyzed in a systematic manner how lipid metabolism and immune regulation are connected at the transcriptional level via this receptor. Here we present the genome-wide expression analyses ...
Background: Acute coronary syndrome (ACS) is an amplified state of inflammation and immune reaction. Dendritic cells (DCs) expressing various Toll-like receptors (TLRs) have been observed in atherosclerotic lesions, however, the clinical significance of DCs in pathogenesis of ACS has not been completely investigated. Methods: Ten patients with ACS and 10 patients with stable angina pectoris (SA...
HLDA10 is the Tenth Human Leukocyte Differentiation Antigen (HLDA) Workshop. The HLDA Workshops provide a mechanism to allocate cluster of differentiation (CD) nomenclature by engaging in interlaboratory studies. As the host laboratory, we invited researchers from national and international academic and commercial institutions to submit monoclonal antibodies (mAbs) to human leukocyte surface me...
The effects of ADP on the biology of dendritic cells have been studied much less than those of ATP or adenosine. In this study, we showed that adenosine-5'-O-(2-thiodiphosphate) (ADPβS) induced intracellular Ca(2+) transients in murine dendritic cells (DCs). This effect was abolished by AR-C69931MX, a dual P2Y(12) and P2Y(13) receptor antagonist. RT-PCR experiments revealed the expression of bo...
To understand the lack of protective immunity observed after infection with parainfluenza virus type 3 (PIV3), we tested the effect of the virus on human monocytes and monocyte-derived immature dendritic cells (DCs). Expression of viral antigens on the cell surfaces correlated with replication of the virus, which was marginal in monocytes but extremely efficient in DCs. The virus increased mono...
Dendritic cells (DCs) phagocytose apoptotic influenza-infected monocytes and cross-present influenza antigen to CD8+ T cells, generating a specific CTL response. We investigated whether apoptotic melanoma cells, presented by this mechanism, can lead to CTL responses to tumor-associated antigens and melanoma cells. Apoptotic HLA-A2- MEL-397 melanoma cells were internalized by HLA-A2+ immature mo...
The Wharton's jelly of the umbilical cord is believed to be a source of mesenchymal stem cells (MSCs) which can be therapeutically applied in degenerative diseases.In this study, we investigated the immunomodulatory effect of umbilical cord derived-mesenchymal stem cells (UC-MSCs) and bone marrow-derived-mesenchymal stem cells (BM-MSCs) on differentiation, maturation, and endocytosis of monocyt...
