The pathogenesis of aspirin-induced asthma (AIA) is presumed to involve the aspirin /non-steroidal anti-inflammatory drug (NSAID)-induced abnormal metabolism of arachidonic acid, resulting in an increase in 5-lopoxygenase (5-LO) metabolites, particularly leukotriene C4 (LTC4) which is a highly potent bronchial constrictor. However, the role of LTC4 in the development of AIA has yet to be conclusively demonstrated. To elucidate the effect of LTC4 on the development of AIA, we generated LTC4 synthase (Ltc4s) gene transgenic (LTC4S-Tg) mice. In contrast to wild-type (WT) mice, LTC4S-Tg mice displayed NSAID-induced airway obstruction that was associated with increases of LTC4 and Th2 cytokines in lung tissue. This is the first study to demonstrate... |

Scientific literature is the primary resource for relevant and innovative information. The integration of the literature with other data resources in the biomedical research community generates overhead that can be avoided through the used of Semantic Web Technology generating openly accessible data. Projects such as SESL and CALBC have producted significant amount of data that that are ready for exploitation.
The tutorial will teach different approaches on how to integrate the scientific literature with the content from biomedical databases, and will discuss the inferences that can be achieved. Furthermore, the tutorial will point to the resources that are ready for use and enable integration of the literature at your discretion. A good... |

Two important challenges to the use of serological assays for influenza surveillance include the substantial amount of experimental effort involved, and the inherent noisiness of serological data. Here, informed by the observation that log-transformed serological data (obtained from the hemagglutination-inhibition assay) exist in an effectively one-dimensional space, computational methods are developed for accurately and efficiently recovering unmeasured serological data from a sample of measured data, and systematically minimizing noise found in the measured data. Careful application of these methods would enable the collection of better-quality serological data on a greater number of circulating influenza viruses than is currently possible, and improve... |

Graft-versus-host disease (GVHD) is a serious complication after allogeneic stem cell transplantation, the mechanism of it is still not elucidated. Recent findings suggest that host endothelial cells are a target of alloreactive donor cytotoxic T lymphocytes in GVHD and tissue factor (TF) plays an important role not only in coagulation-inflammation cycle, but also in transplant immunology. We postulate TF expression in vascular endothelial cells(VEC) may play an pivotal role in the pathogenesis of GVHD. TF gene andprotein expression in target organs of GVHD in aGVHD mice was significantly elevated compared to that of controls as determined by real-time PCR and Western blotting. Allogeneic CD4^+^T cell and CD8^+^T cells enhanced TF, VCAM-1, TNF-[alpha],... |

Mast cell activation, mediates type-1 allergic responses, one of the most powerful reactions of the immune system. However, mast cells activation is becoming increasingly linked to inflammatory, autoimmunity, and to adaptive immunity by regulating T-cell activation.
Here we analyzed the gene expression pattern in IgE-sensitized and FcεRI aggregation on human mast cells. Our data revealed coordinated changes in gene expression. We observed increased expression of gene-transcripts involved in allergic, innate and adaptive
immune responses. Among the most prominent findings is the increased expression of transcripts encoding for MIP3a, SPARCL1, AREG, IL18, CCL1, TNFRSF9, IL1b, CX3CR1, PTGER3, MIF, MMP12, ADORA3,... |

Lawrence Corey; Brigitte Autran; Louis Picker; the Working Group convened by the Global HIV Vaccine Enterprise. |
The Global HIV Vaccine Enterprise (the Enterprise) convened a two-day workshop on 17-18 September 2009, at the Enterprise offices in New York; to discuss approaches to bridging the gaps between fundamental,preclinical and clinical HIV vaccine research. The topic of this Working Group originated from discussions of the Enterprise Science Committee,which proposed that more effective collaboration between these three areas of HIV vaccine research is needed in order to accelerate the pace of scientific progress in the field. Because the meeting took place before the release of the RV144 trial results held in Thailand, the conclusions reached during the meeting were further discussed during consultations at scientific conferences and at a joint meeting of the... |

Investigation and experimental design of the study was basically aimed at developing insight into the antigenicity of spermatozoa-associated proteins. Apart from studying the natural antigenicity of washed whole spermatozoa, their immunogenicity was also demonstrated _in vitro_. The whole live spermatozoa were immobilized and agglutinated _in vitro_ by the antibodies they induced in the laboratory model - a female rabbit. A regular immunization routine induced a high titre of antisperm polyclonal antibodies. To prepare a spermatozoa specific antigen which will not produce a cross-reacting antibody against other human tissues, only the motile and live spermatozoa were selected for antigen preparation. In investigation the laboratory-bred female rabbits were... |

Computational models of the immune system (IS) and pathogenic agents have several applications, such as theory testing and validation, or as a complement to first stages of drug trials. One possible application is the prediction of the lethality of new Influenza A strains, which are constantly created due to antigenic drift and shift. Here, we present several simulations of antigenic variability in Influenza A using an agent-based approach, where low level molecular antigen-antibody interactions are explicitly described. Antigenic drift and shift events are analyzed regarding the virulence of emergent strains against the IS. Results are discussed from a qualitative point of view taking into account recent and generally recognized immunology and influenza... |

Acute and chronic progression of injury to the kidney leads to the failure of the renal system and has become an increasingly important cause of morbidity and mortality. Present diagnosis detects the condition only after irreversible loss of 70 percent of kidney function. Current research is focused only on the clinical manifestations after the kidney injuries and not towards the exact cause of the condition. Here we propose a new outlook- that there is an involvement of a pathogen in the pathogenesis of kidney injuries. Basis for our proposal is given by the similarity of the pathogenesis events occurring between a classical example of hepatitis and kidney injuries. Furthermore, literature regarding the role of early kidney injury biomarkers in innate... |

Alzheimer's disease is a common neurodegenerative disorder. However, its exact etiology is still unknown. There were several mechanisms proposed such as the tau hypothesis and amyloid hypothesis. However, there is evidence challenging the above two hypotheses. Here, I propose the immune-amyloid hypothesis as a mechanism for Alzheimer's disease. Th17 related autoimmunity contributes to the disease pathogenesis. Accumulation of misfolded beta amyloid can trigger heat shock protein which in turn induces TH17 immunity. By microarray analysis of peripheral blood mononuclear cells, there is up-regulation of many TH17 related molecules after Alzheimer's disease. After knowing the exact disease pathogenesis, we can develop new... |
