We previously demonstrated that coxsackievirus B3 (CVB3) infection upregulated heat shock protein 70 (Hsp70) and promoted CVB3 multiplication. Here, we report the underlying mechanism by which Hsp70 enhances viral RNA translation. By using an Hsp70-overexpressing cell line infected with CVB3, we found that Hsp70 enhanced CVB3 VP1 translation at two stages. First, Hsp70 induced upregulation of VP1 translation at the initiation stage via upregulation of IRES trans-acting factor La protein and activation of eIF4E binding protein 1, a cap-dependent translation suppressor...

BACKGROUND: Plant-parasitic nematode interactions occur within a vast molecular plant immunity network. Following initial contact with the host plant roots, plant-parasitic nematodes (PPNs) activate basal immune responses. Defence priming involves the release in the apoplast of toxic molecules derived from reactive species or secondary metabolism. In turn, PPNs must overcome the poisonous and stressful environment at the plant-nematode interface. The ability of PPNs to escape this first line of plant immunity is crucial and will determine its virulence...

: The airway mucosa expresses protective interferon (IFN) and inflammatory cytokines in response to Respiratory Syncytial Virus (RSV) infection. In this study, we examine the role of bromodomain containing 4 (BRD4) in mediating this innate immune response in human small airway epithelial cells. We observe that RSV induces BRD4 to complex with NFκB/RelA. BRD4 is functionally required for expression of the NFκB-dependent inflammatory gene regulatory network (GRN), including the IFN Response Factor (IRFs)-1 and -7 that mediate a cross-talk pathway for RIG-I upregulation...

Cancer remains a leading cause of mortality and morbidity worldwide. In addition to organ failure, the most frequent reasons for admission of cancer patients to intensive care units (ICU) are: infections and sepsis. As critically ill, the complexity of the health situation of cancer patients renders the standard antimicrobial regimen more complex and even inadequate which results in increased mortality rates. This is due to pathophysiological changes in the volume of distribution, increased clearance, as well as to organ dysfunction...

BACKGROUND: Parenteral nutrition (PN) administered via central venous catheter has been identified as an independent risk factor for central line-associated bloodstream infections (CLABSIs). The aim of this study was to provide an updated description of the relationship between PN and CLABSI and assess temporal trends in CLABSI rates for individuals who received PN from 2009-2014, after the Centers for Medicare & Medicaid declared CLABSI a "never event." METHODS: Using data obtained from all adult patient discharges between January 1, 2009, and December 31, 2014, from 2 affiliated hospitals in a large health system in New York City, univariate and multivariate analyses were performed to examine the relationship between PN and CLABSIs as well as temporal trends...

Tuberculosis (TB) is a disease caused by Mycobacterium tuberculosis. Despite the availability of novel therapeutic approaches, TB is considered as one of the leading causes of death due to infectious diseases worldwide. Alveolar macrophages are the first line of defense against M. tuberculosis; they ingest and sequester the bacilli within granulomatous structures. Control and resolution of the infection requires activated T lymphocytes as well as Th1 cytokines. There are two forms of TB: active TB and latent TB...

Final epidemic size relations play a central role in mathematical epidemiology. These can be written in the form of an implicit equation which is not analytically solvable in most of the cases. While final size relations were derived for several complex models, including multiple infective stages and models in which the durations of stages are arbitrarily distributed, the solvability of those implicit equations have been less studied. In this paper the SIR homogeneous mean-field and pairwise models and the heterogeneous mean-field model are studied...

BACKGROUND: The advent of highly active antiretroviral therapy (ART) has reduced the morbidity and mortality due to HIV infection. The World Health Organization (WHO) ART guidelines focus on three classes of antiretroviral drugs, namely nucleoside or nucleotide reverse transcriptase inhibitors (NRTI), non-nucleoside reverse transcriptase inhibitors (NNRTI) and protease inhibitors. Two of the most common medications given as first-line treatment are the NNRTIs, efavirenz (EFV) and nevirapine (NVP)...

Adenoviral infections of the central nervous system are rare, but they are characteristic for their high mortality rate. People with impaired immunity and children are particularly vulnerable. A few reports of neuroinfections caused by adenoviruses are found in literature. In this study the tropism of the human adenoviruses type 4, 5, 7 to primary cultures of murine neurons and the influence of infection on the neuron morphology and actin cytoskeleton was examined. The A549 non-small-cell lung cancer cell line was used as a reference line...
