Granzymes are the essential downstream effector molecules for the control of primary virus infections by cytolytic leukocytes. (1/174)

Analysis of perforin-deficient mice has identified the cytolytic pathway and perforin as the preeminent effector molecule in T cell-mediated control of virus infections. In this paper, we show that mice lacking both granzyme A (gzmA) and granzyme B (gzmB), which are, beside perforin, key constituents of cytolytic vesicles, are as incapable as are perforin-deficient mice of controlling primary infections by the natural mouse pathogen ectromelia, a poxvirus. Death of gzmAxgzmB double knockout mice occurred in a dose-dependent manner, despite the expression of functionally active perforin and the absence of an intrinsic defect to generate splenic cytolytic T cells. These results establish that both gzmA and gzmB are indispensable effector molecules acting in concert with perforin in granule exocytosis-mediated host defense against natural viral pathogens.  (+info)

Combined hepatic vein, umbilicoportal vein, and superior mesenteric artery catheterization in portal hypertension: estimation of the portal fraction of total hepatic blood flow in cirrhotic patients. (2/174)

Hemodynamic data were obtained in 13 cirrhotic patients with severe portal hypertension, undergoing combined hepatic vein, umbilicoportal vein, and superior mesenteric artery catheterization. The relative clearance of indocyanine green, the portohepatic gradient (difference between the free portal venous pressure and the free hepatic venous pressure), and the estimated hepatic blood flow were measured. The portal fraction (PF) of total hepatic blood flow was calculated in all patients using indicator dilution curves obtained from the portal bifurcation, a right hepatic vein, and when possible a left hepatic vein (six cases) after injection of (51)Cr-labeled red blood cells ((51)Cr RBC) into the superior mesenteric artery. Flows were overestimated because of loss of indicator through spontaneous portosystemic shunts; however, the ratio between hepatic and portal indicator dilution curves can be used to calculate the portal fraction of total hepatic blood flow since no extrahepatic shunts existed after the bifurcation of the portal vein (as shown on portography). In 10 patients, 15 series of curves were calculable and the PF varied between 30.1 and 100% (mean +/- SE: 71.1 +/- 6.2%). In the three other patients, only delayed activity from recirculation was detected from portal and hepatic vein samples and PF was 0%; in these three cases, portography and arteriography revealed spontaneous portacaval shunting with reverse and/or stagnant circulation in the portal vein. In the 13 patients, no correlation existed between PF and the relative clearance of indocyanine green or the portohepatic gradient, parameters generally used as indices of severity in cirrhosis. In 10 patients, no correlation was found between PF and the estimated hepatic blood flow.These data indicate that (51)Cr RBC dilution curves can be used for the estimation of the portal fraction of total hepatic blood flow in conscious cirrhotic patients before portacaval shunts. Using this methodology, it could be assessed whether any critical level of portal fraction exists above which poor clinical results occur after portacaval shunting. This measurement could eventually be helpful in determining the appropriate surgical procedure to be applied in individual cases.  (+info)

Chromium isotopes and the fate of hexavalent chromium in the environment. (3/174)

Measurements of chromium (Cr) stable-isotope fractionation in laboratory experiments and natural waters show that lighter isotopes reacted preferentially during Cr(VI) reduction by magnetite and sediments. The 53Cr/52Cr ratio of the product was 3.4 +/- 0.1 per mil less than that of the reactant. 53Cr/52Cr shifts in water samples indicate the extent of reduction, a critical process that renders toxic Cr(VI) in the environment immobile and less toxic.  (+info)

The estimation of red cell volume with 51Cr-labelled erythrocytes and plasma volume with radioiodinated human serum albumin. (4/174)

The validity of a simplified procedure for the direct estimation of both red cell and plasma volume, using (51)Cr-labelled erythrocytes and radioiodinated human serum albumin, has been examined. It is suggested that the procedure, involving three venepunctures only, will yield accurate measurements of both compartments.  (+info)

DIAGNOSTIC VALUE OF SERUM HAPTOGLOBIN. (5/174)

Serum haptoglobin has been estimated quantitatively in 25 patients with haemolytic disease, and its diagnostic value assessed by comparing the levels with those obtained in 110normal subjects, in 149 patients with other forms of anaemia, and in 37 patients with non-haematological disorders. The normal range was found to be 33 to 213 mg./100 ml.; subnormal levels were found in 80% of patients with haemolytic disease or megaloblastic anaemia, patients with haemorrhage into the tissues, and occasionally in association with other diseases. When taken in conjunction with other clinical and laboratory features this simple biochemical estimation can be of diagnostic value.  (+info)

NK cell-induced cytotoxicity is dependent on a Ca2+ increase in the target. (8/174)

In previous work we showed that programmed cell death (PCD) in thymocytes is mediated by a sustained increase in cytosolic Ca2+ concentration, resulting in the activation of an endogenous endonuclease, DNA fragmentation, and cell death. In this study we investigated the roles of Ca2+ and DNA fragmentation in target cell killing by natural killer (NK) cells. The effector cells induced a rapid, sustained increase in cytosolic Ca2+ concentration in Jurkat target cells. Buffering the target cell cytosolic Ca2+ with the Ca2(+)-selective dye, quin-2, prevented target cell killing. Extensive DNA fragmentation was associated with killing in every target tested, and this response was also blocked by quin-2. The endonuclease inhibitor, aurintricarboxylic acid, inhibited both DNA fragmentation and killing without influencing the Ca2+ increase in target cells. Thus, it is concluded that NK cell killing depends on a Ca2+ increase and appears to involve endogenous endonuclease activation in target cells.  (+info)

As the famous writer, philosopher and politician, Benjamin Franklin (the guy on the $100 bill) once said, An ounce of prevention is worth a pound of cure. A team of British scientists took it upon themselves to develop a smart wound dressing that changes color when it comes into contact with certain bacteria. In a wound, bacteria from the surrounding skin and other sources quickly find their way in and start to multiply forming colonies. This is absolutely normal, but there are some cases where the bacterial load reaches a critical point, at which immune clearance is no longer effective. Its at this point that medical intervention becomes a must, so Ben Franklin hit the nail right on the head.. ...

Fibroblast growth factor 19 entry into brain | Fluids and Barriers of the CNS | Full TextFibroblast growth factor 19 entry into brain | Fluids and Barriers of the CNS | Full Text
We first showed that human FGF19 was stable in mouse blood and its half-time disappearance was further extended by excess FGF19. In the hot only group, there was no meaningful permeation of 125I-FGF19 into brain as seen by multiple-time regression analysis. The initial volume of distribution of 125I-FGF19 remained higher than that of co-administered 131I-albumin. The presence of FGF19 in the cerebral vasculature may allow its binding and activation of BBB endothelia and thus induce CNS function indirectly without crossing the BBB, as seen with adiponectin [19]. Nevertheless, the small portion of FGF19 entering the brain was stable for at least 10 min, so that it could exert direct CNS effects.. The influx of 125I-FGF19 became significant in the presence of excess unlabeled FGF19 or its homolog FGF15 both by multiple-time regression analysis after iv injection and by in-situ brain perfusion. Because of the low level of permeation without an increase of Vi over time, we did not perform capillary ...

Oncolytic viruses and immune clearanceOncolytic viruses and immune clearance
Oncolytic viruses are a concept Id like to be more excited by than I am.2 Its an idea that seemed really exciting when I first came across it, but the more I thought about it the more dubious I was. But a recent paper helps me feel better about at least two of my worries.. The concept is a straightforward one. Viruses are good at killing cells.3 Why not have them infect cells that we want to die? That would be, for example, cancer cells. So all you need to do is find or make a virus that only grows in cancer cells, and youre cured. Simple! Tomorrow well fix global warming!. Theres the obvious problem with this: How can you find (or make) a cancer-specific virus? In principle the answer is the same as with chemotherapy; you use the ways cancer cells are different from normal as targets. This isnt as hard as you might think. Lots of the things that make cancer cells cancerous are similar to the things viruses like. Viruses often drive infected cells into a cancer-like state that is more ...

Human-induced pluripotent stem cell-derived macrophages and their immunological function in response to tuberculosis infection ...
Macrophages (Mφ) are one of the most important immune cells in the body and are distributed in most tissues and organs. These cells play a central role in the non-specific immune clearance of bacteria, viruses, fungal pathogens, and specific immune response antigen presentation and corresponding cytokine production [1]. While traditionally tissue-resident, Mφ have been regarded as being continuously replenished from hematopoietic stem cells via the intermediate step of peripheral blood monocytes, this concept has recently been challenged [2].Thus, studies have recently demonstrated that substantial populations of Mφ are prenatally seeded and exhibit considerable longevity (months to years); in addition, these cells have, at least in part, self-renewal potential [3, 4].. Additionally, CD34+ hematopoietic stem cells, monocytes and early T lymphocytes, etc. [5] can be differentiated into macrophages under certain conditions. There are two main sources of human macrophages in vitro. One source is ...

Functional dissection of phagocytosis in Nervous system development and the immune system of Drosophila melanogasterFunctional dissection of phagocytosis in Nervous system development and the immune system of Drosophila melanogaster
Phagocytes remove apoptotic cells during development and eliminate pathogens in the immune system. The underlying molecular and cellular mechanisms, particularly the differences between macrophages and non-professional phagocytes like glia, are not well understood. We used novel cell-based assays to screen phagocytic function of candidate genes assembled from literature and our genome-wide transcription profiling of Drosophila melanogaster embryonic glia. Gene function was knocked-down by RNAi and phagocytic efficiency assessed by flow cytometry; to explore functional specificity, we offered not only bacteria, but also apoptotic cells and beads as food. To validate results in vivo, we analysed glial clearance of apoptotic neurons in embryonic development and immune clearance of bacteria in adult flies using both genetic mutants and transgenic RNAi. Our screen provides a cross section of the different steps of phagocytosis from recognition to engulfment and phagosomal degradation. For the ...

The aim of the present study was to delineate the therapeutic effect of a vaccine with chitosan as an adjuvant, as well as to identify the potential mechanism against infection when compared with an vaccine, with cholera toxin (CT) as an adjuvant. adjuvant to the vaccine were significantly greater than those in the groups with CT as an adjuvant. The mRNA expression levels of TLR4 and Foxp3 were significantly elevated in the mice that were vaccinated with chitosan as an adjuvant to the vaccine, particularly in mice where the infection had been eradicated. The vaccine with chitosan as an adjuvant effectively increased the elimination rate, the humoral immune response and the Th1/Th2 cell immune reaction; in addition, the therapeutic vaccine regulated the Th1 and Th2 response. The significantly increased TLR4 expression and decreased CD4+CD25+Foxp3+Treg cell number contributed to the immune clearance of the infection. Thus, the present Tandutinib findings demonstrate that in mice the vaccine with ...

Most protozoa survive environmental stress by encapsulating to form a cyst or spore. This process is medically important because cysts of pathogenic protists are resistant to immune clearance, antibiotics and biocides. In addition, cysts of bacterivorous protists such as Acanthamoeba castellani are exploited act as vectors for survival and airborne dispersal by bacterial pathogens, such as Legionella pneumoniae and MRSA. Due to the limited genetic tractability of encysting organisms, the mechanisms controlling encystation are largely unknown.. Dictyostelid social amoebas survive stress by building fruiting structures with encapsulated spores and stalk cells. Both cell types mature in response to cAMP activation of PKA. We showed earlier that this process is evolutionary derived from encystation in solitary amoebas, which we found to also require cAMP acting on PKA. The encysting Dictyostelid Polysphondylium pallidum is uniquely suitable for both reverse and forward genetic approaches, which ...

Molecular Architecture and Assembly Principles of Vibrio cholerae Biofilms | ScienceMolecular Architecture and Assembly Principles of Vibrio cholerae Biofilms | Science
Many bacterial infections involve biofilm formation. Cells within a biofilm are significantly more resistant to immune clearance and antibiotics compared to unattached, planktonic cells. Berk et al. (p. 236) applied superresolution optical methods to image living bacteria with nanometer-scale precision as they form a biofilm. Vibrio cholerae biofilms were observed to have three distinct levels of spatial organization: cells, clusters of cells, and collections of clusters. Each cell cluster was wrapped in a flexible, elastic envelope. Several V. cholerae matrix proteins played complementary architectural roles during biofilm development. RbmA provided cell-cell adhesion, Bap1 allowed the developing biofilm to adhere to surfaces, and heterogeneous mixtures of VPS, RbmC, and Bap1 formed the dynamic, flexible, and ordered envelopes that encase the cell clusters. ...

Chronic hepatitis B virus (HBV) infection in endemic areas usually starts since infancy and early childhood and persists lifelong. The clinical course varies among different chronic infected subjects. Majority of chronic HBV infected children present with immune-tolerant status initially, experience the immune clearance phase with various degree of liver injury during or beyond puberty, and then enter the inactive phase after hepatitis B e antigen (HBeAg) seroconversion. Part of them may have HBV DNA titers elevation with hepatitis flare after HBeAg seroconversion, the so call HBeAg-negative hepatitis flare. Liver cirrhosis, and even hepatocellular carcinoma may develop afterward. The complex course of chronic HBV infection is associated with the age/route of viral acquisition, host factors such as immune and endocrine factors, viral factors, and host-viral interactions. The adrenarche and puberty onset modulate the start of immune clearance and the severity of liver inflammation in chronic HBV infected

The role of BST-2/Tetherin in host protection and disease manifestatio by Wadie D. Mahauad-Fernandez and Chioma M. Okeoma
Host cells respond to viral infections by activating immune response genes that are not only involved in inflammation, but may also predispose cells to cancerous transformation. One such gene is BST-2, a type II transmembrane protein with a unique topology that endows it tethering and signaling potential. Through this ability to tether and signal, BST-2 regulates host response to viral infection either by inhibiting release of nascent viral particles or in some models inhibiting viral dissemination. However, despite its antiviral functions, BST-2 is involved in disease manifestation, a function linked to the ability of BST-2 to promote cell-to-cell interaction. Therefore, modulating BST-2 expression and/or activity has the potential to influence course of disease.

Group 2 innate lymphocytes at the interface between innate and adaptive immunity | Meta
Group 2 innate lymphoid cells (ILC2) are innate immune cells that respond rapidly to their environment through soluble inflammatory mediators and cell-to-cell interactions. As tissue-resident sentinels, ILC2 help orchestrate localized type 2 immune responses. These ILC2-driven type 2 responses are now recognized in diverse immune processes, different anatomical locations, and homeostatic or pathological settings. ILC2-derived cytokines and cell surface signaling molecules function as key regulators of innate and adaptive immunity. Conversely, ILC2 are governed by their environment. As such, ILC2 form an important nexus of the immune system and may present an attractive target for immune modulation in disease. ...

Sabinet | The erythron in health and disease - a kinetic approach to Erythrocytosis and AnaemiaSabinet | The erythron in health and disease - a kinetic approach to Erythrocytosis and Anaemia
In conclusion, the concept of the erythron is discussed as a logical way to approach the physiology of erythropoiesis and as a basis for understanding the pathophysiological disturbances whIch characterise the red cell abnormalities. Using this approach, both increase in red cell mass, or erythrocytosis, and decrease in red cell mass, or anaemia, are seen simply as manifestations of a disturbance in the normal regulatory mechanisms of the erythron.

Ribbon-Cutting Ceremony Celebrates Completion of Chromium-6 Treatment Plant - Cal WaterRibbon-Cutting Ceremony Celebrates Completion of Chromium-6 Treatment Plant - Cal Water
Cal Water held a ribbon-cutting ceremony to commemorate the completion of a chromium-6 (Cr-6) treatment plant in its Dixon District yesterday. Mayor Jack Batchelor and representatives from Senator Lois Wolk, Assemblymembers Bill Dodd and John Garamendis offices; Solano County Supervisor John Vasquez, among other local officials, were in attendance.. The treatment plant, one of three plants Cal Water has constructed in the past year, will reduce the amount of naturally occurring Cr-6 from the local water supply. In July 2014, the State of California set the countrys first regulation for Cr-6, allowing no more than 10 parts per billion (ppb) of the constituent be in water provided to consumers. Wells in Cal Waters Dixon District had naturally occurring Cr-6 levels ranging from 15-24 ppb; however, since the treatment plants came online, the water supply in the Dixon District has remained in compliance with the new state standard.. In order to find the most effective solution, Cal Waters Water ...

Project overview - SINGEK
The first research work package comprises laboratory work (WP3), which includes single cell sorting, nucleic acid amplification from the minute quantities in a single cell, and highthroughput sequencing. The second is bioinformatics (WP4), by which the billions of short sequences are processed into comprehensive datasets, requiring assembly into larger contigs, gene prediction and annotation, and reconstruction of metabolic pathways. The generated genomic data is then exploited to address scientific questions within two tightly interconnected disciplines, which if tackled separately could not be answered. Fundamental ecological questions (WP5) include the study of the biodiversity of natural samples, cell-to-cell interactions, and gene complements of uncultured lineages that could explain their lifestyle and ecological function. Evolutionary questions (WP6) include the addition of uncultured lineages to retrieve a more complete eukaryotic Tree of Life, understanding the evolution of genes and ...
