Although the transcription factors IRF-3 and IRF-7 are considered master regulators of type I interferon (IFN) induction and IFN stimulated gene (ISG) expression, Irf3(-/-)×Irf7(-/-) double knockout (DKO) myeloid dendritic cells (mDC) produce relatively normal levels of IFN-β after viral infection. We generated Irf3(-/-)×Irf5(-/-)×Irf7(-/-) triple knockout (TKO) mice to test whether IRF-5 was t...

Purpose We develop a longitudinal statistical model describing best-corrected visual acuity (BCVA) changes in anti-VEGF therapy in relation to imaging data, and predict the future BCVA outcome for individual patients by combining population-wide trends and initial subject-specific time points. Methods Automatic segmentation algorithms were used to measure intraretinal (IRF) and subretinal (SR...

This manuscript presents the first extensive phylogenetics analysis of a key family of immune regulators, the interferon regulatory factor (IRF) family. The IRF family encodes transcription factors that play important roles in immune defense, stress responses, reproduction, development, and carcinogenesis. Several times during their evolution, the IRF genes have undergone expansion and diversif...

ADISSA is a methodology for Architectural Design of Information Systems and Software, based on Structured Analysis. The architectural design includes: (a) design of a tree-structured menu system, which interfaces between the users and the system-viewed as the “external architecture” of the system; and (b) design of the transactions of the system, composed of various functions which are activate...

Delivery of transcription factors to cancer cells to reprogram gene expression may represent a novel strategy to augment the production of immune stimulatory cytokines and trigger a more potent antitumor response. In the present study, a bicistronic retroviral vector (AP2) was used to transduce B16-F0 melanoma cells with IFN regulatory factor (IRF)-3, which has been shown to activate type I IFN...

BACKGROUND Interferon-induced 35-kDa protein (IFP35) plays important roles in antiviral defense and the progression of some skin cancer diseases. It can be induced by interferon-γ (IFN-γ) in multiple human cells. However, the mechanisms by which IFN-γ contributes to IFP35 induction remain to be elucidated. METHODS/PRINCIPAL FINDINGS We identified the transcription start sites of IFP35 by 5' r...

TLR9 is critical for the recognition of unmethylated CpG DNA in innate immunity. Accumulating evidence suggests distinct patterns of TLR9 expression in various types of cells. However, the molecular mechanism of TLR9 expression has received little attention. In the present study, we demonstrate that transcription of murine TLR9 is induced by IFN-beta in peritoneal macrophages and a murine macro...

One of the basic topics of QA dialogue systems is how follow-up questions should be interpreted by a QA system. In this paper, we shall discuss our experience with the IMIX and Ritel systems, for both of which a follow-up question handling scheme has been developed, and corpora have been collected. These two systems are each other’s opposites in many respects: IMIX is multimodal, non-factoid, b...

BACKGROUND Previous research has shown that internet education can lead to short-term improvements in clinicians' knowledge, confidence and communication practices. We wished to better understand the duration of these improvements and whether different curriculum delivery strategies differed in affecting these improvements. METHODS As previously described, we conducted a randomized control tr...
