Committed T helper type 1 (Th1) and Th2 effector cells, resulting from chronic antigenic stimulation in interleukin (IL)-12 and IL-4, are implicated in the pathology of autoimmune and allergic diseases. Committed Th1 cells cannot be induced to change their cytokine profiles in response to antigenic stimulation and Th2 cytokine-inducing conditions. Here, we(More)
We have recently reported (1) the isolation of a cDNA sequence coding for human IL-4 B cell stimulatory factor 1 (BSF,) .' This lymphokine is a T cell-derived glycoprotein consisting of 129 amino acids with two potential N-glyco-sylation sites. Human IL-4 is able to induce the proliferation of activated B Takebe, et al. manuscript submitted for(More)
Plasmacytoid dendritic cells (pDCs) produce copious type I interferon (IFN) upon sensing nucleic acids through Toll-like receptor (TLR) 7 and TLR9. Uncontrolled pDC activation and IFN production are implicated in lymphopenia and autoimmune diseases; therefore, a mechanism controlling pDC IFN production is essential. Human pDCs specifically express an orphan(More)
Plasmacytoid dendritic cells (pDCs) are specialized type I interferon (IFN-α/β)-producing cells that express intracellular toll-like receptor (TLR) 7 and TLR9 and recognize viral nucleic acids in the context of infections. We show that pDCs also have the ability to sense host-derived nucleic acids released in common skin wounds. pDCs were found to rapidly(More)
Plasmacytoid dendritic cells (pDCs) play an important primary role for antiviral innate immunity by rapidly producing large amounts of type 1 interferon (IFN) upon viral infection. To study pDC biology, we generated a monoclonal antibody, termed 2E6, that recognizes pDCs. Molecular cloning of a cDNA encoding the 2E6 antigen revealed that it is a type II(More)
The commitment of naive T cells to polarized Th cells requires specific changes in their transcription factors. Retrovirally overexpressed GATA-3 has been reported to induce the Th2 cytokine profile in developing Th1 cells. In this study, we examined the role of the N-terminal finger (Nf) of GATA-3 in Th2 cell development. The Nf, as well as the C-terminal(More)

Plasmacytoid dendritic cells (pDCs) link innate to acquired immune responses by producing high levels of type I IFN upon infection. In order to identify the specific genes that control pDC, we compared serial analysis of gene expression libraries from human pDCs, herpes simplex virus-stimulated pDCs and monocytes. We found that Ig-like transcript ILT7 is(More)
In response to antigenic stimulation, helper T cells secrete a set of protein mediators called lymphokines that regulate proliferation, differentiation, and maturation of lymphocytes and hemopoietic cells. Because all known lymphokines are composed of a single polypeptide chain, their coding sequences can be isolated by functional expression in appropriate(More)
Patients with glycogen storage disease (GSD) type 1b have shown normal activity of glucose-6-phosphatase (EC as assayed in frozen liver, though their clinical and biochemical findings were similar to those of patients with GSD 1a (McKusick 23220) (Senior and Loridan, 1968). In 1978, we suggested that a basic defect of GSD 1b exists in the(More)
