Chronic immune activation, triggered by plasmacytoid dendritic cell (PDC) interferon (IFN)-alpha production, plays an important role in HIV-1 pathogenesis. As the entry of HIV-1 seems to be important for the activation of PDC, we directly characterized the viral entry into these cells using immuno-electron microscopy, cellular fractionation, confocal imaging, and functional experiments. After a...
Mitochondrial pyruvate dehydrogenase complex (PDC) is crucial for glucose homeostasis in mammalian cells. The current understanding of PDC regulation involves inhibitory serine phosphorylation of pyruvate dehydrogenase (PDH) by PDH kinase (PDK), whereas dephosphorylation of PDH by PDH phosphatase (PDP) activates PDC. Here, we report that lysine acetylation of PDHA1 and PDP1 is common in epiderm...
Plasmacytoid dendritic cells (pDC) produce type I interferons (IFN-I) and proinflammatory cytokines in response to viruses; however, their contribution to antiviral immunity in vivo is unclear. In this study, we investigated the impact of pDC depletion on local and systemic antiviral responses to herpes simplex virus (HSV) infections using CLEC4C-DTR transgenic mice. We found that pDC do not ap...
Plasmacytoid dendritic cells (PDCs) represent a unique immune cell type specialized in type I interferon (IFN) secretion in response to viral nucleic acids. The molecular control of PDC lineage specification has been poorly understood. We report that basic helix-loop-helix transcription factor (E protein) E2-2/Tcf4 is preferentially expressed in murine and human PDCs. Constitutive or inducible ...
BACKGROUND In a mouse model of viral induced atopic disease, expression of FcεRI on dendritic cells is critical. While adult human conventional (cDC) and plasmacytoid (pDC) dendritic cells have been shown to express FcεRI, it is not known if this receptor is expressed in childhood and how its expression is governed by IgE. METHODS Following informed consent of subjects (n = 27, aged 12-188 mo...
The cost and the time-to-market for a product will increase exponentially if innovations are not brought and deployed into the product development cycle (PDC). This is due to the fact the system complexity is increasing exponentially with time. This increasing complexity results from introduction of new protocols, higher radio frequencies, and increasing number of applications, among others, in...
Given their immune-modulating capacity, regulatory T cells (Treg) cells may be important players in the induction of the protective T-cell response (Th1) to genital chlamydial infection. Recent work has demonstrated that plasmacytoid dendritic cells (pDC) respond to genital chlamydial infection, and that pDC may be uniquely positioned for the induction of Treg cells during this infection. Here,...
The plasmacytoid dendritic cell (pDC) is vital to the coordinated action of innate and adaptive immunity. pDC development has not been unequivocally traced, nor has its transcriptional regulatory network been fully clarified. Here we confirm an essential requirement for the BCL11A transcription factor in fetal pDC development, and demonstrate this lineage-specific requirement in the adult organ...
Pyruvate decarboxylase (PDC encoded by pdc) is a thiamine pyrophosphate (TPP)-containing enzyme responsible for the conversion of pyruvate to acetaldehyde in many mesophilic organisms. However, no pdc/PDC homolog has yet been found in fully sequenced genomes and proteomes of hyper/thermophiles. The only PDC activity reported in hyperthermophiles was a bifunctional, TPP- and CoA-dependent pyruva...
An alternative to clinical trial paper-based data collection (PDC) is internet based electronic data collection (EDC), where the investigators over the internet enter data directly in the electronic database by themselves. In our study we considered clinical trial as a business process. Our objective was to model PDC and EDC process and to estimate the difference of the costs of PDC and EDC pro...
