The somatic hEGFR kinase domain mutations are highly correlated with the clinical response to gefitinib or erlotinib therapy in lung cancer patients. Our findings that these hEGFR kinase domain mutants are oncogenic in vivo and that their continual expression is necessary for tumor maintenance validate the importance of the mutated enzyme as a therapeutic target. EGFR-targeted therapy against murine cancers overexpressing hEGFR mutants is dramatically effective, suggesting that these mutants are directly involved in tumor maintenance. These inducible mouse models will be useful for evaluation of a new generation of EGFR inhibitors as well as other novel therapeutics prior to human clinical trials.

PATIENTS AND METHODS Patients Our sample consisted of 126 patients with HD that were followed up over the period from Janaury 1992 to December 1996 at Hematology Division of Unifesp EPM. The admissions for the first-line treatment of these patients were from December 1976 to December 1996. Sufficient paraffin-embedded blocks of diagnostic tissues were available in relation to 51 patients from this sample for performing new histological analyses with hematoxylin-eosin staining and for making immunohistochemistry slides.

By severe, protracted and often fatal infection, which results from a failure of the NADPH oxidase enzyme system in the patient's phagocytes to produce superoxide. The NADPH oxidase enzyme system is composed of a number of interacting components, the absence of any one of which causes failure of the system as a whole. Investigation of individuals with CGD has led to the identification of the different protein components and the genes coding for them. CGD is particularly well suited to treatment by gene therapy and is likely to be one of the earliest monogenic conditions to be successfully treated in this way.

Radioactivity in the plasma samples and the tissue homogenates was determined by liquid scintillation counting Tri-Carb 2100 CA Liquid Scintillation analyzer, Canberra Packard, Groningen, the Netherlands ; . Pharmacokinetic and statistical analyses. Pharmacokinetic parameters after administration of imatinib were calculated by noncompartmental methods using the software package MW version 3.02, MediWare, Groningen, the Netherlands ; . The area under the plasma concentrationtime curve AUC ; was calculated from 0 to 120 minutes i.v. imatinib ; or from 0 to 240 minutes p.o. imatinib ; using the linear-logarithmic trapezoidal method. The clearance was calculated by the formula Cl dose AUC 15 ; . The two-sided unpaired Student's t test was used to assess the statistical significance of difference between two sets of data. Results are presented as means F SD. Differences were considered to be statistically significant when P 0.05. Calculation of brain penetration of imatinib. We determined the brain concentration of imatinib by measuring the radioactivity in whole brain homogenates, which were collected 2 hours after administration of i.v. imatinib or 4 hours after administration of p.o. imatinib. Because imatinib has a low CNS distribution 810 ; , we subtracted the concentration of imatinib in the brain vascular space i.e., 1.4% of the plasma concentration at t 2 hours for i.v. imatinib or at t hours for p.o. imatinib ; from the brain concentration found in whole brain homogenates 11 ; . We then calculated the brain penetration of i.v. imatinib by determining the imatinib brain concentration at t 2 hours relative to the plasma AUC 0-2 hours ; , as the AUC better reflects the overall imatinib exposure to the brain than the plasma concentration at 2 hours after administration. The brain penetration of p.o. imatinib was calculated in the same manner using the AUC 0-4 hours and mycostatin.

1-3-D-Arabinofuranosylcytosine Ara-C ; is one of the most important drugs in the treatment of human acute leukemia 1-4 ; . A significant increase in the selectivity of Ara-C may have farreaching consequences for the management of this disease. AraC behaves as an analog of deoxycytidine dCyd ; that, when phosphorylated to 1-, 3-D-arabinofuranosylcytosine triphosphate Ara-CTP ; , is a potent inhibitor of DNA polymerase 5-7 ; and is also incorporated into DNA 7-9 ; . The activity of Ara-C is determined by the amount of Ara-CTP formed within the cell, and the concentration of the natural substrate deoxycytidine triphosphate dCTP ; , with which Ara-CTP must compete for binding to DNA polymerase 5, 6, 10, ; . Phosphorylation of Ara-C is normally constrained by feedback inhibition ofdCTP on dCyd kinase, the enzyme catalyzing the rate-limiting step in the dCyd salvage pathway 12, 13 ; . Thymidine dThd ; has been shown to increase the toxicity of Ara-C in vitro and in vivo against several murine 14-17 ; and human tumors 16 ; . This is in part due to the ability of thymidine triphosphate dTTP ; to inhibit ribonucleotide reductase 18 ; , which catalyzes an obligatory step in the die novo synthesis of dCTP 19, 20 ; and depletes the cellular dCTP pool 15, 18, 19, ; .

Notes: 15 to 20 minutes will produce 3-5 ppm parts per million ; with most distilled water. Water with a higher alkalinity often found in the east ern U.S. and Canada ; produces a higher ppm. If timed for longer, the Silver Colloid will be a pale yellow color. With most of the waters we tested, this occurred at about 6 to 9 ppm depending on the water. If grey or black flakes appear, filter before using. It is important the Silver Wires do not touch each other. A slightly higher ppm is produced when the silver wires are a uniform 12" apart for the length of the submers ed wire. The White Bulb should remain off or be dimly lit when making Colloidal Silver. If the light shines brightly it means either the two Silver Wires are touching each other or there are too many impurities or minerals in the water you are using. Try a different brand of distilled water. Storage: Store in a dark glass bottle-- never metal-- in the cupboard or other dark place. Always store in a dark place as sunlight or room light will quickly degrade silver colloid by turning the solution grey or black-- just as exposure to light darkens the silver in camera film. Light neutralizes positive charges on silve r ions that help keep-the particles in suspension. ; Do not freeze. Do not refrigerate or expose to other rapid temperature cha nges such as a hot car ; or its usefulness will be affected. Do not drink any sediment. Do not use a glass measuring cup. A metal kettle that has been coated can be used, a glass cooking pot, or glass beaker with wire under it and mysoline.

Daszak1; 1 Consortium for Conservation Medicine, New York, NY, 2New York State Department of Health, Slingerlands, NY, 3Smithsonian Migratory Bird Center, Washington, DC. Background: West Nile virus WNV ; has caused repeated large-scale human epidemics in North America since it was first detected in 1999 and is now the dominant vector-borne disease in this continent. Understanding the factors that promote epidemics and determine the intensity of the spillover of this zoonotic pathogen from birds to humans via mosquitoes ; is a prerequisite for predicting and preventing human epidemics. Methods: We used PCR and DNA sequencing of mosquito blood meals to study mosquito feeding behavior and integrated these data with the population dynamics and WNV epidemiology of mosquitoes, birds, and humans. Results: We show that Culex pipiens, the dominant enzootic bird-tobird ; and bridge bird-to-human ; vector of WNV in urbanized areas in the northeast and north-central US, shifted from feeding primarily on a single avian in summer to feeding on humans in the fall. Heterogeneity in hostvector contact rates and host reservoir competence inflated the reproductive rate of WNV ten fold and led to the existence of a community super spreader. The feeding shift to humans coincided with the dispersal of Cx. pipiens' preferred host and the rise in human WNV infections. Conclusions: Our results provide a direct explanation for the timing and intensity of human WNV epidemics and underscore the dramatic effects of vector behavior in driving the transmission of zoonotic pathogens to humans.
Platinum therapy with and without the addition of doxorubicin11-14 but none found any significant clinical improvement. Furthermore, in the study of Du Bois et al.15, the addition of epirubicin to the standard treatment with carboplatin an paclitaxel did not improve overall survival but induced a significantly higher rate of myelotoxicity. Only a recent meta-analysis was able to demonstrate a modest but significant 7% improvement in survival in the doxorubicin-containing arms16. Furthermore, the toxicity of doxorubicin limited its use alone or in combination with other agents. Pegylated liposomal doxorubicin Doxyl, Schering Plough ; is a newly marketed formulation consisting of a preparation of doxorubicin and a liposome containing surface-grafted segments of the hydrophilic polymer methoxypolyethylene glycol PEG ; . The liposomal PEG coating increases surface hydrophilicity, decreases opsonization and the uptake of doxorubicin by the spleen and reticuloendothelial system, and prolongs liposome circulation time. The elimination half-life of liposomal doxorubicin in humans is therefore longer than that of free doxorubicin 45 vs 18-30 hrs ; 17. Preclinical studies of PEG-coated liposomes have shown greater liposomal doxorubicin accumulation in solid murine tumors, ascites18 and human biopsy specimens of Kaposi's sarcoma19. Preclinical studies and clinical experience indicate that liposomal doxorubicin may be more efficacious and nadolol.

Of the Th1 class.61 Tregs are activated in an antigen-specific manner, perhaps with involvement of IL-10, TGF- , and immature dendritic cells, causing them to express high levels of CD25 IL-2 receptor alpha chain ; constitutively.53 They are unresponsive to mitogens, express CTLA-4, and are able to block production of IL-2 and interferon IFN- ; by effector T cells in a manner that relies on cell-to-cell contact. Most reports suggest that Tregs function in an antigen-nonspecific manner as tested in vitro, although at least one report suggested that they may be antigen specific in vivo.62 Tregs may also have inhibitory effects on APCs, and their high expression of CCR4 and CCR8 suggests aberrant trafficking.53 Recently, a distinction has been made between "natural" Tregs, important in preventing autoimmune responses to continually expressed antigens in the noninflammatory setting, and "adaptive" Tregs, which are important in developing tolerance to foreign antigens and quelling inflammatory processes.63 In murine models, infusion of CD4 CD25 T cells is able to prevent acute GVHD while graft-versus-tumor is maintained.64, 65 Removal of CD4 CD25 T cells from the graft or blockade by CD25 antibodies worsened acute GVHD.66 Another model suggested that chronic GVHD incidence and severity is higher in the absence of recipient CD4 CD25 cells, and that repletion with recipient or host Tregs is protective.11 These murine observations led to the hypothesis that human chronic GVHD results from a low Treg population, and that expansion ex vivo and replacement could help control chronic GVHD. However, a small study of 17 patients with chronic GVHD showed higher numbers of CD4 CD25 cells in people with chronic GVHD but lower CD62 ligand CD62L ; expression compared with people without chronic GVHD, although absolute numbers and functionality were similar to controls.67 A more recent study of people considered to have allogeneic or autologous chronic GVHD quantified Foxp3 expression as a marker of Tregs and suggested that they may indeed be deficient.68 Thus, it remains controversial whether Tregs are involved in chronic GVHD, and further studies are warranted and nafcillin.

A number of strains of Abelson murine leukemia virus A-MuLV ; with various abilities to transform cells have been identified. Among these is the A-MuLV-P90 strain, a mutant derived from A-MuLV-P120 that encodes an A-MuLV protein missing sequences that are normally present at the extreme carboxy terminus of P120 N. Rosenberg and 0. N. Witte, J. Virol 33: 340-348, 1980 ; . This virus transforms NIH 3T3 cells efficiently but does not transform a high frequency of lymphoid cells in vitro or in vivo. In this communication, we show that of the relatively few tumors induced by A-MuLV-P90 nearly all contained new variant viruses that stably expressed either larger or smaller A-MuLV proteins. Strains that expressed larger A-MuLV proteins behaved like A-MuLV-P120 in transformation assays, whereas those expressing smaller A-MuLV proteins induced a high frequency of tumors after a short latent period in vivo but failed to transform large numbers of lymphoid cells in vitro. Thus, these latter viruses separated the requirements for in vitro transformation of lymphoid cells from those for tumor induction. All of the variants differed from A-MuLV-P90 in the carboxy-terminal region of the A-MuLV protein, suggesting that sequences in this region play a key role in the ability of the virus to interact with hematopoietic cells in vivo and in vitro and murine.

Or IL-10 ; , were identified in vivo in the murine model of low zone tolerance or in patients suffering from leprosy.57, 58 Anergic CD8 T cells induced by IL-10treated DCs inhibit the proliferation of cocultured CD8 T cell in an antigen-specific manner without any effect on cocultured DCs as observed by analyzing the accessory capacity and the expression of surface molecules on DCs after coculture with anergic T cells unpublished data ; . Furthermore, similar to anergic CD4 T cells, anergic CD8 T cells with suppressor activity do not release immunosuppressive cytokines. The concept that anergic CD4 T cells can exert regulatory effects as suppressor cells was demonstrated in vivo and in vitro.25, 26, 59-62 More importantly, to the best of our knowledge, this study is the first report to show that human anergic CD8 T cells have suppressor properties. Our observation that IL-10treated DCs induce anergic CD4 CD8 T cells with antigen-specific suppressor activity opens new therapeutic perpectives for the use of DCs in vivo. Induction of anergic T cells might be exploited therapeutically for suppression of cellular immune responses in allergic or autoimmune diseases with identified auto- ; antigens and naltrexone.

In recent years, our laboratory has developed a rapid in vitro radiometric assay for the evaluation of the viability of Mycobacterium leprae. Over a 2- to 3-week period, 150 human-derived M. leprae strains maintained in mouse peritoneal and human monocyte-derived macrophage cultures showed significant uptake of [3H]thymidine as compared with parallel cultures of heatkilled bacilli obtained from the same skin biopsy 16, 20 ; . That the incorporation of the radiolabel was in the bacilli and not in the host cells was shown by DNase experiments 8, 20 ; . This assay has been effectively used to study the effect of dapsone 4, 4'-diaminodiphenyl sulfone ; and to identify dapsone-resistant strains 14 ; . Moreover, immunologically mediated inhibition of [3H]thymidine incorporation was observed in M. leprae resident macrophage cultures in the presence of antigen-induced lymphokines derived from responder tuberculoid leprosy patients 17 ; . This rapid in vitro assay compared well with the commonly used mouse footpad model 15, 18, 19, ; . Concordant results were obtained when biopsies obtained from clinically suspected dapsone-resistant patients were studied in the macrophage assay and mouse foot model in two independent centers 14 ; .

These results indicate that while iNOS may be involved in controlling chlamydial replication during the midpoint of the infection, its activity is not essential to resolution of the infection. We then sought to determine the reason for the apparent disparity in the observations in our experiments and in those of previously published works 7, 14, 19 ; . We hypothesized that IFN- controlled chlamydial replication independently of iNOS activity. Therefore, we assessed the effect of IFN- on chlamydial replication in various cells derived from iNOS KO and control mice. Following sacrifice of uninfected iNOS KO or control animals, organs were aseptically removed and processed to obtain single-cell suspensions by a standard collagenase D stainlesssteel mesh filtration procedure. Cells were plated in Eagle's minimal essential medium containing 10% heat-inactivated 56C, 30 min ; fetal bovine serum and 2 mM L-glutamine at 1 ml per well in 24-well plates. Primary cell cultures were monitored daily with an inverted microscope and fed by replacing medium at 2- or 3-day intervals. Upon reaching confluency or near confluency usually 9 to 12 days in culture ; , the cells were used in the nitric oxide induction and chlamydial growth assays described below. To obtain peritoneal macrophages, cells were harvested by peritoneal lavage 72 h after intraperitoneal injection with 1 ml of 3% Proteose Peptone DIFCO, Detroit, Mich. ; . Following enumeration, the cell suspension was diluted to 2 105 cells ml, plated at 1 ml per well in 24-well plates in Eagle's minimal essential medium with 10% fetal bovine serum, and allowed to adhere for 24 h prior to use. Initially, single-cell preparations from several tissues were screened for their ability to form monolayers in culture and to support chlamydial growth. From these results, we determined that cell cultures from urinary bladder and lung tissues were best suited for our purposes. These preparations from iNOS KO and control mice were found to be predominantly fibroblasts at confluency by indirect fluorescent-antibody staining with fibroblast-specific goat antivimentin 1: 20; ICN Biomedical, Aurora, Ohio ; followed by fluorescein-labeled rabbit antigoat immunoglobulin 1: 200; ICN Biomedical ; . Treatment of murine cells with IFN- and LPS induces iNOS to produce nitric oxide from L-arginine, resulting in the accumulation of nitrite in culture supernatants. This response can be blocked by the presence of the arginine analog LNMMA 12 ; . Therefore, we assessed nitrite accumulation in the primary cell cultures described above in response to IFNand LPS in the presence and absence of L-NMMA. Culture medium was aspirated from primary murine cell lines and macrophages and replaced with medium containing either IFN- 50 ng ml; Pharmingen, San Diego, Calif. ; plus LPS 100 ng ml; Sigma ; , IFN- plus LPS plus 1 mM L-NMMA Calbiochem, La Jolla, Calif. ; , fresh medium plus L-NMMA, or fresh medium only for 48 h. Nitrite accumulation was assessed by the Greiss reaction 11 ; . Treatment of cells from control mice with IFN- and LPS resulted in marked nitrite production in the supernatants of each of the primary cultures P 0.005, by a two-tailed t test, in each case compared with that in controls with medium only ; while the presence of LNMMA completely reversed this response data not shown ; . As expected, no nitrite was detected at any time in supernatants of primary cell cultures derived from iNOS KO mice. We also assessed IDO activity by previously published methods 6 ; but were unable to detect any activity, as indicated by a lack of accumulated tryptophan catabolites in the culture supernatants data not shown and naratriptan.
