Bystander effects caused by nonuniform distributions of DNA-incorporated (125)I. (1/402)

A three-dimensional tissue culture model was used to investigate the biological effects of nonuniform distributions of DNA-incorporated (125)I in mammalian cells. Chinese hamster V79 cells were labeled with (125)I-iododeoxyuridine, mixed with unlabeled cells, and multicellular clusters ( approximately 1.7 mm in diameter) were formed by gentle centrifugation. The highly localized energy deposition caused by (125)I decays results in very high equivalent doses delivered to the labeled cells and low equivalent doses delivered to the unlabeled cells. The clusters were assembled and then maintained at 10.5 degrees C for 72 h to allow (125)I decays to accumulate, dismantled, and the cells were plated for colony formation. When 100% of the cells were labeled, the survival fraction was exponentially dependent on the mean radioactivity per labeled cell. A two-component exponential response was observed when either 50 or 10% of the cells were labeled. These experimental data, coupled with theoretical dosimetry calculations, indicate that bystander effects play an important role in the killing of unlabeled cells when nonuniform distributions of DNA-incorporated (125)I are present.  (+info)

Neonatal exposure to antigen primes the immune system to develop responses in various lymphoid organs and promotes bystander regulation of diverse T cell specificities. (2/402)

Neonatal exposure to Ag has always been considered suppressive for immunity. Recent investigations, however, indicated that the neonatal immune system could be guided to develop immunity. For instance, delivery of a proteolipid protein (PLP) peptide on Ig boosts the neonatal immune system to develop responses upon challenge with the PLP peptide later. Accordingly, mice given Ig-PLP at birth and challenged with the PLP peptide as adults developed proliferative T cells in the lymph node that produced IL-4 instead of the usual Th1 cytokines. However, the spleen was unresponsive unless IL-12 was provided. Herein, we wished to determine whether such a neonatal response is intrinsic to the PLP peptide or could develop with an unrelated myelin peptide as well as whether the T cell deviation is able to confer resistance to autoimmunity involving diverse T cell specificities. Accordingly, the amino acid sequence 87-99 of myelin basic protein was expressed on the same Ig backbone, and the resulting Ig-myelin basic protein chimera was tested for induction of neonatal immunity and protection against experimental allergic encephalomyelitis. Surprisingly, the results indicated that immunity developed in the lymph node and spleen, with deviation of T cells occurring in both organs. More striking, the splenic T cells produced IL-10 in addition to IL-4, providing an environment that facilitated bystander deviation of responses to unrelated epitopes and promoted protection against experimental allergic encephalomyelitis involving diverse T cell specificities. Thus, neonatal exposure to Ag can prime responses in various organs and sustain regulatory functions effective against diverse autoreactive T cells.  (+info)

In vivo gene therapy for colon cancer using adenovirus-mediated, transfer of the fusion gene cytosine deaminase and uracil phosphoribosyltransferase. (3/402)

Virus-directed enzyme prodrug therapy (VDEPT) utilising cytosine deaminase (CD) converts 5-fluorocytosine (5-FC) into the chemotherapy agent, 5-fluorouracil (5-FU), and has entered into a clinical trial for metastatic colon cancer. To improve this system, a replication-deficient adenovirus, containing a bifunctional fusion gene, CD:uracil phosphoribosyltransferase (UPRT), was constructed (AdCDUPRT). UPRT enhances the conversion of 5-FU into its active metabolites, which inhibit DNA and RNA synthesis. In vitro, AdCDUPRT infection of colon cancer cells resulted in a marked increase in sensitisation to 5-FU, compared with AdCD-infected or uninfected cells. The corollary is a approximately 100-fold and approximately 10 000-fold increase in sensitisation to 5-FC in AdCDUPRT-infected cells, compared to AdCD-infected and uninfected cells, respectively. There was a strong bystander effect in vitro, 70% of tumour cells were killed by 5-FC when only 10% of cells expressed CDUPRT. In vivo, athymic mice with colon cancer xenografts treated with intratumoral AdCDUPRT and intraperitoneal 5-FC, significantly reduced tumour growth rates compared with untreated controls (P = 0.02), whereas AdCD/5-FC treated mice did not. At higher AdCDUPRT virus doses, 5-FC and 5-FU were equally effective at delaying tumour growth compared with controls. In summary, VDEPT for colon cancer utilising AdCDUPRT is more effective than AdCD and the bifunctional CDUPRT gene enables the use of either 5-FC or 5-FU as prodrugs.  (+info)

Inflammatory-type responses after exposure to ionizing radiation in vivo: a mechanism for radiation-induced bystander effects? (4/402)

Haemopoietic tissues exposed to ionizing radiation are shown to exhibit increased macrophage activation, defined by ultrastructural characteristics and increased lysosomal and nitric oxide synthase enzyme activities. Macrophage activation post-irradiation was also associated with enhanced respiratory burst activities and an unexpected neutrophil infiltration. Examination of p53-null mice demonstrated that macrophage activation and neutrophil infiltration were not direct effects of irradiation, but were a consequence of the recognition and clearance of radiation-induced apoptotic cells. Increased phagocytic cell activity was maintained after apoptotic bodies had been removed. These findings demonstrate that, contrary to expectation, recognition and clearance of apoptotic cells after exposure to radiation produces both a persistent macrophage activation and an inflammatory-type response. We also demonstrate a complexity of macrophage activation following radiation that is genotype dependent, indicating that the in vivo macrophage responses to radiation damage are genetically modified processes. These short-term responses of macrophages to radiation-induced apoptosis and their genetic modification are likely to be important determinants of the longer-term consequences of radiation exposure. Furthermore, in addition to any effects attributable to immediate radiation-induced damage, our findings provide a mechanism for the production of damage via a 'bystander' effect which may contribute to radiation-induced genomic instability and leukaemogenesis.  (+info)

Local inflammation and devascularization--in vivo mechanisms of the "bystander effect" in VPC-mediated HSV-Tk/GCV gene therapy for human malignant glioma. (5/402)

Somatic gene therapy with the herpes simplex virus type I thymidine kinase gene/ganciclovir (HSV-Tk/GCV) system and murine retroviral vector producer cells (VPCs) was introduced as a new adjuvant treatment modality to treat tumor bulk and to prevent tumor recurrence in patients harboring malignant glioma. The single-center experience after treatment of 27 patients undergoing tumor resection followed by intracerebral VPC injection for HSV-Tk suicide gene therapy will be presented focused on findings of systematic and close MRI follow-up and a few histological specimens. The data indicate that hemorrhagic necrosis due to endothelial cell transfection mediated vessel necrosis and that local inflammatory immune response occurs frequently after gene therapy. These phenomena seem to be specific because none of the patients of a control group showed any similar features. The prognosis (time to progression, survival) of the patients with "bystander effects" after gene therapy was better, but compared to those patients without bystander effects, they were also privileged by a favorable constellation of prognostic factors. Therefore, the appearance of these neuroradiologic features cannot serve as an indicator for treatment effectiveness and outcome.  (+info)

Indirect IL-4 pathway in type 1 immunity. (6/402)

Recall Ag-specific IL-4 was detected in the spleen and in the blood, but not in lymph nodes of mice in which polarized type 1 immunity was induced. This IL-4 was not produced by T cells, but soluble factors secreted by the recall Ag-activated T cells, including IL-3, triggered cells of the innate immune system, primarily mast cells, to secrete IL-4. This notion has profound implications for immunodiagnostics: the detection of apparently recall Ag-specific IL-4 does not necessarily reflect the presence of Th2 or Th0 memory T cells with long-term cytokine commitment as is of interest for assessing adoptive immunity. We found that in vivo the indirect IL-4 pathway did not suffice to trigger IgE isotype switching, but promoted IgG1 production and inhibited type 1 T cell differentiation. Therefore, the indirect IL-4 pathway can explain partial type 2 immune response phenotypes in vivo in face of unipolar Th1 T cell immunity. The representation of mast cells in different tissues may explain why immune responses in certain organs are more type 2 biased. Therefore, the indirect pathway of IL-4 production represents a novel type of interaction between the innate and the adoptive immune system that can contribute to the outcome of host defense and immune pathology.  (+info)

Characteristics of ovarian cancer cells transduced by the bicistronic retroviral vector containing GM-CSF and HSV-TK genes. (7/402)

OBJECTIVES: To explore whether HSV-TK (herpes simplex virus thymidine kinase) and GM-CSF (granulocyte-macrophage colony-stimulating factor) genes could be linked by internal ribosome entry site (IRES) in one retroviral vector and expressed by ovarian cancer cells following transfection, and to observe the characteristics of the transduced cells. METHODS: Retroviral vector pLGM-I-TK was constructed by linking the HSV-TK gene and GM-CSF gene with the IRES sequence. By using the "ping-pong" technique, pLGM-I-TK was transfected into the packaging cell line, PA317, to produce a PA317/TK-GM cell line. Using the resulting viral supernatant to infect the ovarian cancer cell line SKOV3, PCR and RT-PCR were used to explore the integration and transcription of HSV-TK and GM-CSF genes. The cytotoxicity of GCV (gancyclovir) on SKOV3/TK-GM was determined by MTT assay and the bystander effect of the HSV-TK/GCV system was also assessed. ELISA was used to measure the expression of GM-CSF by the transgene cells. RESULTS: The bicistronic retroviral vector constructed could be successfully transduced into PA317 and the titer of the retroviral vector was about 8.6 x 10(5) cfu/ml. PCR and RT-PCR demonstrated the successful integration and transcription of HSV-TK and GM-CSF genes transduced into the SKOV3 cell. SKOV3/TK-GM cells could be killed by GCV, and the IC50 was 0.7 microgram/ml. The bystander effect was demonstrated. The expression level of GM-CSF in SKOV3/TK-GM was 60.4 ng.ml-1 x 10(6) cells-1 x 2 days-1. CONCLUSION: The IRES sequence can be used to construct retroviral vectors to facilitate co-transfection of two genes. SKOV3/TK-GM cells can simultaneously express the HSV-TK and GM-CSF genes with biological activities which could be useful for enhancing the function of immune cells on the basis of suicide gene therapy.  (+info)

Sensitization of prostate cancer cell lines to 5-fluorocytosine induced by adenoviral vector carrying a CD transcription unit. (8/402)

OBJECTIVE: To investigate the efficiency of the cytosine deaminase adenoviral/5-fluorocytosine system on prostate cancer cell lines. METHODS: We used cell culture, infectivity and sensitivity tests, to observe bystander effect by animal tests. RESULTS: Established prostate cancer cell lines are eventually infectible by adenoviral vector. The ratio of vector/cell at which infection occurs depends on the specific cell line. The peak of expression of the transferred cytosine deaminase gene occurred in cells at different time, but persisted beyond 11 days. These prostate cell lines are sensitized to 5-fluorocytosine by infection with adenoviral vector carrying the cytosine deaminase gene. Only 5% of the LNCap and 10% of the RM-1 cells were infected and produced 100% cell death. In the animal test, there was significant inhibition of tumor growth at a ratio of 400 vector particles/cell with the systematic treatment of 5-fluorocytosine. CONCLUSIONS: Adenoviral vector carrying a cytosine deaminase transcription unit can sensitize prostate cancer cell lines to 5-fluorocytosine. The system can significantly inhibit the growth of prostatic tumors in mice.  (+info)

TY - JOUR. T1 - Long-Term consequences of radiation-induced bystander effects depend on radiation quality and dose and correlate with oxidative stress. AU - Buonanno, Manuela. AU - De Toledo, Sonia M.. AU - Pain, Debkumar. AU - Azzam, Edouard I.. PY - 2011/4. Y1 - 2011/4. N2 - Widespread evidence indicates that exposure of cell populations to ionizing radiation results in significant biological changes in both the irradiated and nonirradiated bystander cells in the population. We investigated the role of radiation quality, or linear energy transfer (LET), and radiation dose in the propagation of stressful effects in the progeny of bystander cells. Confluent normal human cell cultures were exposed to low or high doses of 1GeV/u iron ions (LET ∼151 keV/μ m), 600 MeV/u silicon ions (LET ∼51 keV/μ m), or 1 GeV protons (LET ∼0.2 keV/μ m). Within minutes after irradiation, the cells were trypsinized and co-cultured with nonirradiated cells for 5 h. During this time, irradiated and ...
TY - JOUR. T1 - Role of TGF-beta1 and nitric oxide in the bystander response of irradiated glioma cells.. AU - Shao, C.. AU - Folkard, M.. AU - Prise, Kevin. PY - 2008/1/17. Y1 - 2008/1/17. N2 - The radiation-induced bystander effect (RIBE) increases the probability of cellular response and therefore has important implications for cancer risk assessment following low-dose irradiation and for the likelihood of secondary cancers after radiotherapy. However, our knowledge of bystander signaling factors, especially those having long half-lives, is still limited. The present study found that, when a fraction of cells within a glioblastoma population were individually irradiated with helium ions from a particle microbeam, the yield of micronuclei (MN) in the nontargeted cells was increased, but these bystander MN were eliminated by treating the cells with either aminoguanidine (an inhibitor of inducible nitric oxide (NO) synthase) or anti-transforming growth factor beta1 (anti-TGF-beta1), indicating ...
Evidence has accumulated that ionizing radiation induces biological effects in non-irradiated bystander cells having received signals from directly irradiated cells; however, energetic heavy ion-induced bystander response is incompletely characterized. Here we performed microarray analysis of irradiated and bystander fibroblasts in confluent cultures. To see the effects in bystander cells, each of 1, 5 and 25 sites was targeted with 10 particles of carbon ions (18.3 MeV/u, 103 keV/microm) using microbeams, where particles traversed 0.00026, 0.0013 and 0.0066% of cells, respectively. diated cells, cultures were exposed to 10% survival dose (D), 0.1D and 0.01D of corresponding broadbeams (108 keV/microm). Irrespective of the target numbers (1, 5 or 25 sites) and the time (2 or 6h postirradiation), similar expression changes were observed in bystander cells. Among 874 probes that showed more than 1.5-fold changes in bystander cells, 25% were upregulated and the remainder downregulated. These ...
p,Radiation induced bystander effects have given the cancer risk analysis a whole new paradigm. However the actual mechanism involved in producing the effects is still not clear. The basic bystander signal is assumed to be a biological signal. In this study we proposed and tried to quantify the presence of a physical signal in the form of electromagnetic radiation that can trigger a biological response in the bystander cells. In bystander effect studies where the cells are exposed to very low fluence of charged particles there could be several regions that can produce electromagnetic radiation due to the process of atomic/molecular excitations and relaxations. We focused on quantifying the number of ultraviolet photons emitted when charged particles pass through different media that have relevance to radiation biology experiments. The choice of UV photons was made due to the reason that its effects on living cells are very well documented. For this purpose we developed a system which employed ...
It is now well accepted that radiation induced bystander effects can occur in cells exposed to media from irradiated cells. The aim of this study was to follow the bystander cells in real time following addition of media from irradiated cells and to determine the effect of inhibiting these signals. A human keratinocyte cell line, HaCaT cells, was irradiated (0.005, 0.05 and 0.5 Gy) with γ irradiation, conditioned medium was harvested after one hour and added to recipient bystander cells. Reactive oxygen species, nitric oxide, Glutathione levels, caspase activation, cytotoxicity and cell viability was measured after the addition of irradiated cell conditioned media to bystander cells. Reactive oxygen species and nitric oxide levels in bystander cells treated with 0.5Gy ICCM were analysed in real time using time lapse fluorescence microscopy. The levels of reactive oxygen species were also measured in real time after the addition of extracellular signal-regulated kinase and c-Jun amino-terminal kinase

Introduction: Brachytherapy is a preferred choice of radiotherapy in the treatment of sensitive tissues cancer like intestine and gonad. The treatment is expensive because of the frequent replacement of radionuclide sources. A better understanding of cell killing and the cellular responses at different dose rates, might aid in tumor cell killing with fewer doses thereby enhancing a better prognosis.. Methods: The cervix cancer cell line was irradiated with doses ranging from 2Gy-10 Gy at three different dose-rates as used in brachytherapy along with unexposed sample as control. The biological effects of different doses and dose rate of the cells was assessed by measuring its cytotoxicity,genotoxicity and clonogenic ability of exposed cells. The bystander effect was examined by co-culturing the exposed tumor cells with the unexposed normal blood lymphocyte and vice-versa. Results: A significant and dose dependent changes in cell viability (trypan blue exclusion), genotoxicity (Micronucleus assay) ...
Tumor vascular endothelium has certain properties that render it an attractive target for cancer gene therapy, such as accessibility to circulating vectors, expression of endothelial surface receptors distinct from those of normal quiescent vasculature, and a potential amplifying effect caused by hypoxia. Ligand-directed adeno-associated virus/phage can mediate targeted HSVtk suicide gene transfer to tumor vascular endothelium in several experimental models (20, 21). However, the precise cytotoxic mechanism of such profound antitumor effects after vascular-targeted suicide gene transfer has not as yet been entirely understood. Here, we show that vascular targeted HSVtk suicide gene delivery results in efficient cell killing mediated by a heterotypic bystander effect between endothelial and parenchymal tumor cells in vitro and in vivo.. The bystander effect has initially been described as a phenomenon in homotypic cultures, in which neighboring (bystander) HSVtk-nonexpressing tumor cells were ...

EMS providers recorded bystander assistance 11% of the time. The logistic regression model correctly predicted bystander intervention occurrence 71.4% of the time. Bystanders were more likely to intervene when the patient was male (aOR = 1.12, 95% CI = 1.12-1.3) and if the patient was older (progressive aOR = 1.10, 1.46 age group 20-29 through age group 60-99). Bystanders were less likely to intervene in rural areas compared to urban areas (aOR = 0.58, 95% CI = 0.58-0.59). The highest likelihood of bystander intervention occurred in a residential institution (aOR = 1.86, 95% CI = 1.85-1.86) and the lowest occurred on a street or a highway (aOR = 0.96, 95% CI = 0.95-0.96). Using death as a reference group, bystanders were most likely to intervene when the patient had cardiac distress/chest pain (aOR = 11.38, 95% CI = 10.93-11.86), followed by allergic reaction (aOR = 7.63, 95% CI = 7.30-7.99), smoke inhalation (aOR = 6.65, 95% CI = 5.98-7.39), and respiration arrest/distress (aOR = 6.43, 95% CI = ...
Despite many years of potent antiretroviral therapy, latently infected cells and low levels of plasma virus have been found to persist in HIV-infected patients. The factors influencing this persistence and their relative contributions have not been fully elucidated and remain controversial. Here, we address these issues by developing and employing a simple, but mechanistic viral dynamics model. The model has two novel features. First, it assumes that latently infected T cells can undergo bystander proliferation without transitioning into active viral production. Second, it assumes that the rate of latent cell activation decreases with time on antiretroviral therapy due to the activation and subsequent loss of latently infected cells specific for common antigens, leaving behind cells that are successively less frequently activated. Using the model, we examined the quantitative contributions of T cell bystander proliferation, latent cell activation, and ongoing viral replication to the stability ...

To date, acalabrutinib has been used in trials studying the treatment of B-All, Myelofibrosis, Ovarian Cancer, Multiple Myeloma, and Hodgkin Lymphoma, among others. As of October 31, 2017 the FDA approved Astra Zenecas orally administered Calquence (acalabrutinib) medication as a Bruton Tyrosine Kinase (BTK) inhibitor indicated for the treatment of adult patients with Mantle Cell Lymphoma (MCL) who have already received at least one prior therapy, marking the companys first entry into the treatment of blood cancers. Also known as ACP-196, acalabrutinib is also considered a second generation BTK inhibitor because it was rationally designed to be more potent and selective than ibrutinib, theoretically expected to demonstrate fewer adverse effects owing to minimized bystander effects on targets other than BTK. Nevertheless, acalabrutinib was approved under the FDAs accelerated approval pathway, which is based upon overall response rate and faciliates earlier approval of medicines that treat serious

Chronic allograft rejection is in part mediated by host T cells that recognize allogeneic antigens on transplanted tissue. One factor that determines the outcome of a T cell response is clonal size, while another is the effector quality. Studies of alloimmune predictors of transplant graft survival have most commonly focused on only one measure of the alloimmune response. Because differing qualities and frequencies of the allospecific T cell response may provide distinctly different information we analyzed the relationship between frequency of soluble antigen and allo-antigen specific memory IFN-g secreting CD4 and CD8 T cells, their ability to secrete IL-2, and their proliferative capacity, while accounting for cognate and bystander proliferation. The results show proliferative responses primarily reflect on IL-2 production by antigen-specific T cells, and that proliferating cells in such assays entail a considerable fraction of bystander cells. On the other hand, proliferation (and IL-2 production)
We wanted to assess whether B-cell and/or T-cell reactions to collagen and thereby the course of collagen-induced arthritis could be suppressed by regulatory mechanisms associated with oral tolerance to an unrelated protein. splenocyte secretion of IFN- and IL-10 in response to BCII. Our results demonstrate that OVA-specific regulatory occasions induced by nourishing OVA, i.e. bystander suppression, decreased the severe nature of arthritis in animals immunized with OVA and BCII. Anti-BCII particular antibody replies and cytokine secretion by types 1 and 2 T helper cells had been also reduced.

Jackson: I recognize that I am using a very broad definition for bystander engagement: ANYONE who has peers, friends or colleagues, or anyone who plays a leadership role in a social group or institutional setting - which means virtually EVERYBODY. What is required is not just individual but institutional change. This is beginning to happen in the military. MVP has been doing bystander-focused prevention training in the military for 14 years, and it is exciting that now all four major branches of the U.S. military have decided to employ bystander programming system-wide to prevent sexual and domestic violence. For example, by the summer of 2012 the Air Force has mandated that all personnel at every level need to go through what theyre calling Bystander Intervention Training. This training includes examining and interrupting behaviors on an abuse continuum, and also includes elements of media literacy education.. That level of commitment represents an institutional shift. It is promising in part ...
Family lore has it that from ages one to four, hed tied my right hand behind my back so Id grow up to be left-handed, right-brained, and well-centered. I was eight when my father wanted to test the bystander effect as it applies to the black community. He replicated the infamous Kitty Genovese case with a prepubescent me standing in for the ill-fated Ms. Genovese, who, in 1964, was robbed, raped, and stabbed to death in the apathetic streets of New York, her plaintive Psychology 101 textbook cries for help ignored by dozens of onlookers and neighborhood residents. Hence, the bystander effect: the more people around to provide help, the less likely one is to receive help. Dad hypothesized that this didnt apply to black people, a loving race whose very survival has been dependent on helping one another in times of need. So he made me stand on the busiest intersection in the neighborhood, dollar bills bursting from my pockets, the latest and shiniest electronic gadgetry jammed into my ear ...

After seeing a verbal assault on the Metro, one student took steps to deescalate the situation, and told us: Really grateful for your training!. After this class, give myself permission to speak up, I have plans of action, and feel confident to engage.. Inspiring! She makes me feel comfortable addressing scary & uncomfortable situations.. After taking the bystander intervention class, I feel a lot more confident that I could deescalate a dangerous situation.. I feel more safe and proud when I walk down the street. When I see a potentially unsafe situation up ahead, instead of just getting nervous, I can make a plan.. Its apparent that youre genuinely concerned about each student learning the techniques and becoming more confident in verbal confrontations. Its nice to be the recipient of that level of dedication.. ...
Matthew 26 - A little later the bystanders came up and said to Peter, Surely you too are [one] of them; for even the way you talk *gives you away.
In anticipation of a phase I clinical trial in GBM patients using an immunotherapeutic approach that combines Ad-Flt3L with Ad-TK+GCV, it was critical to determine the optimal cytotoxic agent to use in this approach. Therefore, we compared the efficacy and neurotoxicity of Ad-TK+GCV with Ad vectors encoding the proapoptotic cytokines TNF-α, TRAIL, and FasL. Our hypothesis was that Ad-TK+GCV would exhibit superior efficacy and safety when compared with Ads expressing proapoptotic cytokines. Because Ad-TK kills proliferating cells in the presence of GCV (37), we expected this agent to have a powerful antitumor effect due to the presence of mitotic tumor cells within GBM. Also, the bystander effect of phosphorylated GCV would amplify the cytotoxic effect of this approach (37). The highest therapeutic efficacy was indeed achieved when using Ad-TK+GCV by itself for small tumors, and in combination with Ad-Flt3L for large tumors. Although all the proapoptotic Ads certainly induced apoptosis in vitro ...

I think the permit idea is interesting, in a sense. Its interesting in the sense of not being able to turn away, like when you see a bad car accident. Its not that the permit idea is grotesque - its grotesque that society has reached a point where thats a compromise.. It seems to me weve got a pretty good compromise already. Concerned Bystander has to make a choice - and really, its no choice at all. If you really think a child is dying in that car, you break the window, knowing two things: first, that no sane court will convict you on vandalism, etc. charges, second, that even if you would face those charges, youd do it anyway. If you dont really think a child is in danger - if youre trying to feel superior, engage in virtue-flash, etc., its pretty obvious - you dont break the window. Any Concerned Bystander who doesnt actually break into the car, but instead stands around, complaining, pesters the parents when they come back, etc. - either didnt really think the kid was in danger, ...

We show here that CD8 T cells undergo apoptosis and decline in number in response to IFN and that non-virus-specific bystander CD8 T cells are driven to apoptosis during the T-cell response to virus infections. Apoptosis and cell loss in each of these systems were most pronounced in CD8 T cells of the memory phenotype (CD44hi). IFN-induced attrition and apoptosis of memory cells were confirmed using MHC tetramer analysis of a well-defined LCMV memory population from poly(I:C)-injected LCMV-immune mice (Fig. 4 and Table 3). An early virus-induced peak in T-cell apoptosis and attrition correlated with the peak in virus-induced IFN-α/β, and the IFN-α/β inducer poly(I:C) dramatically induced apoptosis and attrition in the memory CD8 T-cell compartment. Poly(I:C) is a very potent IFN-α/β inducer, but it also induces potentially cytotoxic cytokines like TNF alpha (44). IFN-α/β, in turn, can stimulate the synthesis of a number of other cytokines, such as IL-15 (20, 54), which is known to act on ...
In comparison to last year, Ribe has moved upwards in terms of its place among the best restaurants in Estonia. Better still, the restaurant has regained the position that was clearly theirs. Ribe has been one of the best restaurants in Estonia for years and earned that position in every way possible..

The modern concepts of sustainable cities and smart grids have caused an increase in the installation of solar systems in urban and suburban areas, where, due to the presence of many obstacles or design constraints, photovoltaic (PV) modules can operate in operating conditions that are very different from the optimal ones (e.g., standard test conditions, STC). Shading and reflection are the main phenomena that cause uneven distribution of irradiance on PV cells; in turn, they create a nonuniform distribution of PV cell temperatures. The latter problem can also be caused by different ventilation regimes in various parts of the PV array. On the other hand, due to the need to exploit different solar technologies (solar thermal and photovoltaic), problems related to the availability of a useful surface can arise. In this context, there is a technology that produces heat end electrical energy at the same time, such a technology is referred to as a solar hybrid photovoltaic/thermal (PV/T). Here, the ...

T cell proliferation in vivo is presumed to reflect a T cell receptor (TCR)-mediated polyclonal response directed to various environmental antigens. However, the massive proliferation of T cells seen in viral infections is suggestive of a bystander reaction driven by cytokines instead of the TCR. In mice, T cell proliferation in viral infections preferentially affected the CD44hi subset of CD8+ cells and was mimicked by injection of polyinosinic-polycytidylic acid [poly(I:C)], an inducer of type I interferon (IFN I), and also by purified IFN I; such proliferation was not associated with up-regulation of CD69 or CD25 expression, which implies that TCR signaling was not involved. IFN I [poly(I:C)]-stimulated CD8+ cells survived for prolonged periods in vivo and displayed the same phenotype as did long-lived antigen-specific CD8+ cells. IFN I also potentiated the clonal expansion and survival of CD8+ cells responding to specific antigen. Production of IFN I may thus play an important role in the ...

A GM-CSF and CD40L bystander vaccine is effective in a murine breast cancer model Hatem Soliman,1 Melanie Mediavilla-Varela,2 Scott J Antonia,3 1Department of Women's Oncology and Experimental Therapeutics, 2Department of Immunology, 3Department of Thoracic Oncology, Moffitt Cancer Center, Tampa, FL, USA Background: There is increasing interest in using cancer vaccines to treat breast cancer patients in the adjuvant setting to prevent recurrence in high risk situations or in combination with other immunomodulators in the advanced setting. Current peptide vaccines are limited by immunologic compatibility issues, and engineered autologous cellular vaccines are difficult to produce on a large scale. Using standardized bystander cell lines modified to secrete immune stimulating adjuvant substances can greatly enhance the ability to produce immunogenic cellular vaccines using unmodified autologous cells or allogeneic medical grade tumor cell lines as targets. We investigated the efficacy of a cellular

In HIV-1-infected patients, increased numbers of circulating CD8+ T cells are linked to increased risk of morbidity and mortality. Here, we identified a bystander mechanism that promotes CD8 T cell activation and expansion in untreated HIV-1-infected patients. Compared with healthy controls, untreated HIV-1-infected patients have an increased population of proliferating, granzyme B+, CD8+ T cells in circulation. Vβ expression and deep sequencing of CDR3 revealed that in untreated HIV-1 infection, cycling memory CD8 T cells possess a broad T cell repertoire that reflects the repertoire of the resting population. This suggests that cycling is driven by bystander activation, rather than specific antigen exposure. Treatment of peripheral blood mononuclear cells with IL-15 induced a cycling, granzyme B+ phenotype in CD8+ T cells. Moreover, elevated IL-15 expression in the lymph nodes of untreated HIV-1-infected patients correlated with circulating CD8+ T cell counts and was normalized in these ...

Multiple viral and host factors determine the variability in HIV-1 disease progression [17, 23-26]. Cellular tropism and receptor/co-receptor usage for viral entry are major factors influencing HIV pathogenesis. Despite extensive research, the exact mechanism of how those factors contribute to the gradual loss of CD4 T cells is still enigmatic. Bystander CD4 T cell death plays a major contribution towards AIDS progression. A recent report has revealed a mechanism for HIV-induced CD4 T cell depletion, which involves abortive non-productive HIV infection in resting CD4 T cells, followed by IFI16 activation and caspase-1 dependent pyroptosis [27-29]. Besides the abortive RT products in non-productively infected resting cells, several HIV-1 proteins have also been reported to contribute to the depletion of bystander (uninfected and non-productively infected) CD4 T cells, including the Env [4, 5, 17, 19], Vpr [30], Nef [31, 32] and Tat [33]. The Env protein is of specific interest in mediating AIDS ...

Transplant recipients can be sensitized against allo-HLA antigens by previous transplantation, blood transfusion, or pregnancy. While there is growing awareness that multiple components of the immune system can act as effectors of the alloresponse, the role of infectious pathogen exposure in triggering sensitization and allograft rejection has remained a matter of much debate. Here, we describe that exposure to pathogens may enhance the immune response to allogeneic HLA antigens via different pathways. The potential role of allo-HLA cross-reactivity of virus-specific memory T cells, activation of innate immunity leading to a more efficient induction of the adaptive alloimmune response by antigen-presenting cells, and bystander activation of existing memory B cell activation will be discussed in this review ...

The distinction between pathogen mediated and autoaggressive inflammation is becoming increasingly blurred. Current thoughts on the mechanisms of autoimmune disease broadly fall into two camps, not necessarily mutually exclusive. The molecular mimicry theory holds that tolerant self reactive T cells which have escaped deletion in the thymus generally ignore self antigens mostly as a result of factors such as low affinity of their receptors for antigen, and it is not until they are exposed to antigens from micro-organisms which have homology to self antigens that they receive a sufficiently strong stimulus to be activated. The alternative theory of bystander activation suggests that tissue damage induced by micro-organisms releases a variety of cytokines, not always the same set, which under appropriate circumstances activate self reactive T cells which happen to be in the vicinity as they travel through the tissues. Recently, evidence in support of the latter theory has been reported in a model ...

As soon as Peripheral Blood Mononuclear Cells (PBMC) are isolated from whole blood, some cells begin dying. The rate of apoptotic cell death is increased when PBMC are shipped, cryopreserved, or stored under suboptimal conditions. Apoptotic cells secrete cytokines that suppress inflammation while promoting phagocytosis. Increased numbers of apoptotic cells in PBMC may modulate T cell functions in antigen-triggered T cell assays. We assessed the effect of apoptotic bystander cells on a T cell ELISPOT assay by selectively inducing B cell apoptosis using α-CD20 mAbs. The presence of large numbers of apoptotic B cells did not affect T cell functionality. In contrast, when PBMC were stored under unfavorable conditions, leading to damage and apoptosis in the T cells as well as bystander cells, T cell functionality was greatly impaired. We observed that measuring the number of apoptotic cells before plating the PBMC into an ELISPOT assay did not reflect the extent of PBMC injury, but measuring apoptotic cell
