Abstract
Lymphoma is the most frequently diagnosed cancer of the canine haematopoietic system. In this study, the flow cytometry and polymerase chain reaction (PCR) analysis were used to characterize a series of canine lymphomas in detail. The aim of this study was to determine the incidence of B- and T-cell high-grade lymphomas and their immunophenotypic characterization in Lower Silesia, Poland. The results show that the frequency of each type of lymphoma is 71% for B-cell and 17% for T-cell lymphomas. In two cases the PCR techniques confirmed the presence of simultaneous double gene rearrangements of the BCR and TCR receptors.

Abstract
Recent observations indicate that an antiinflammatory process may play a role in the metastatic cascade of renal cell carcinoma (RCC). Therefore, we compared the expression of cytokines from primary human RCC cultures, from established renal carcinoma cells and those from corresponding proximal renal tubulus cells. For this purpose the different cell types were treated with well defined and with bacterial substances such as the lipopolysaccharide, the staphylococcal enterotoxin B, a superantigen, or a combination of the calcium ionophore A23187 and phorbol 12-myristate-13-acetate. The resulting cell supernatants were analyzed for the proinflammatory cytokines (TNF-alpha, IL-6), the chemotactic active interleukin-8 as well as cytokines from T-helper type I (IL-2, IFN-gamma, IL-12) and type II (IL-4, IL-10). In parallel, the expression of cytokine-specific m-RNA was analyzed by multiplex-PCR. Our results clearly demonstrate that among the various cytokines analyzed a predominant release of TNF-alpha, IL-8 and IL-6 is obtained. The remainder cytokines were not detected independent whether molecular biology or cytokine release experiments were applied. Expression of the cytokines was dependent on the degree of malignancy. Among the applied stimuli, only the activation with calcium ionophore/phorbolester modulated cytokine expression and release. While TNF-alpha was induced from normal renal cells by up to 300% (2000 + 120 ng/10(5) cells) a pronounced suppression of TNF-alpha was observed in dependence on the malignancy of the cell line. In contrast, the cytokines IL-6 and IL-8 were significantly upregulated in malignant cells unlike in normal renal cells. These data suggest a differential role of the various cytokines derived from normal or tumor cells. Detailed studies will allow the understanding of the distinct roles of cytokines in renal carcinoma disease.

Abstract
We previously described avian leukosis virus-based packaging cell lines that produce stocks of retroviral vectors in which replication-competent viruses were not detectable. However, following infection of target cells with these retroviral stocks, we recently obtained colonies resulting from the transmission of recombinant genomes. Here, we have analyzed their genetic structure and shown that (i) each of them results from recombination between the packaging- and integration-defective transcomplementing genomes and the retroviral vector; (ii) recombination probably occurred during the reverse transcription step, involving strand switching of the reverse transcription growing point from the infectious retroviral vector to the transcomplementing RNA; and (iii) sequence identity and nonhomologous sequences were both used for the strand switching.

Abstract
Staphylococcus aureus toxic shock syndrome toxin 1 (TSST-1) is involved in the pathogenesis of toxic shock syndrome and perhaps other staphylococcal diseases. Recently, the C-terminal part of the TSST-1 toxin has been shown to be responsible for mitogenic activity in animal models. We studied the role of the C-terminal structural unit of TSST-1 with regard to proliferation, cytokine release (tumor necrosis factor alpha [TNF-alpha], interleukin-6 [IL-6], and IL-8), mRNA expression for IL-6, IL-8, IL-10, TNF-alpha, and CD40 ligand (CD40L), synthesis of immunoglobulin E (IgE), IgA, IgG, and IgM, CD23 expression, and soluble CD23 (sCD23) release from human peripheral blood mononuclear cells (PBMC). For this purpose, we used the recombinant wild-type TSST-1 (p17) mutant toxin Y115A (tyrosine residue modified to alanine) and toxin H135A (histidine residue modified to alanine). Unmodified toxin p17 and mutant toxin Y115A, at a concentration below 5 ng, to a lesser degree, induced a strong proliferation. Toxin p17 followed by toxin Y115A was the most pronounced inducer for mRNA expression for IL-10 and CD40L and cytokine generation (mRNA and protein) for TNF-alpha, IL-6, and IL-8. Mutant protein H135A failed to activate human PBMC. Both toxins p17 and, to a lesser degree, Y115A significantly suppressed IL-4- and anti-CD40-induced synthesis of all four Igs as well as IL-4-induced CD23 expression and sCD23 release. Mutant toxin H135A failed to do so. Thus, our data show that a region in the C terminus of TSST-1 is responsible not only for mitogenic activity but also for additional immunomodulating biological activities of TSST-1. More specifically, histidine residue H135A of the 194-amino-acid toxin appears to be critical for the expression of biological activities in a human in vitro model.

Abstract
On the basis of theoretical structural and comparative studies of various avian leukosis virus SU (surface) envelope proteins, we have identified four small regions (I, II, III, and IV) in their receptor-binding domains that could potentially be involved in binding to receptors. From the envelope gene of an avian leukosis virus of subgroup A, we have constructed a set of SU mutants in which these regions were replaced by the coding sequence of FLA16, a 16-amino-acid RGD-containing peptide known to be the target for several cellular integrin receptors. Helper-free retroviral particles carrying a neo-lacZ retroviral vector were produced with the mutant envelopes. SU mutants in which regions III and IV were substituted yielded normal levels of envelope precursors but were not detectably processed or incorporated in viral particles. In contrast, substitutions in regions I and II did not affect the processing and the viral incorporation of SU mutants. When FLA16 was inserted in region II, it could be detected with antibodies against FLA16 synthetic peptide, but only when viral particles were deglycosylated. Viral particles with envelopes mutated in region I or II were able to infect avian cells through the subgroup A receptor at levels similar to those of the wild type. When viruses with envelopes containing FLA16 peptide in region II were applied to plastic dishes, they were found to promote binding of mammalian cells resistant to infection by subgroup A avian leukosis viruses but expressing the integrins recognized by FLA16. Deglycosylated helper-free viruses obtained by mild treatment with N-glycosidase F have been used to infect these mammalian cells, and infections have been monitored by neomycin selection. No neomycin-resistant clones could be obtained after infection by viruses with wild-type envelopes. Conversely, colonies were obtained after infection by viruses with envelopes bearing FLA16 in region II, and the genome of the retroviral vector was found correctly integrated in cell DNA of these colonies. By using a blocking peptide containing the minimal adhesive RGD sequence contained in FLA16, we have shown that preincubation of target cells could specifically inhibit infection by viruses with FLA16.

Abstract
We have recently described Avian Leukosis Virus (ALV)-based packaging cell lines that can produce helper-free ALV-based retrovirus vectors with A, B, C, and E envelope host ranges. Here, we report that lacZ retroviral vectors of subgroup C or E can infect helper cells of subgroup A (Isolde) which are then able to produce high titers of lacZ recombinant viruses of subgroup A. Superinfection of helper cells by lacZ recombinant virus was performed by cocultivating packaging cells with two subgroup specificities (A and E), but this did not result in increased recombinant virus titers. This "ping-pong" process caused the emergence of replication-competent (RC) viruses which are shown to result from recombination between the viral sequences of the helper cell lines and the cis-acting sequences of the lacZ recombinant virus.

Abstract
Using our previously described Haydée semipackaging cell line (F. L. Cosset, C. Legras, Y. Chebloune, P. Savatier, P. Thoraval, J. L. Thomas, J. Samarut, V. M. Nigon, and G. Verdier, J. Virol. 64:1070-1078, 1990) which produces avian leukosis virus gag and pol proteins, we have constructed packaging cells with subgroups B, C, and E envelope specificities. This allows us to produce helper-free avian leukosis virus particles carrying the lacZ reporter gene and the A, B, C, or E subgroup specificities. Titers of the recombinant lacZ virus are shown to be dependent upon the type of the env subgroup and the target avian cell.

Abstract
Defective avian leukosis-based vectors expressing the bacterial lacZ gene were used as helper-free preparations to infect early stage Brown-Leghorn embryos. Both in toto X-gal staining and DNA analysis using Southern blot technique were applied to detect virus integration and expression. Our results demonstrate a low efficiency of in vitro infection in early stages of embryonic development. Southern blot analysis reveals that only 1% of embryonic cells integrate the vector genome after infection using 2 to 12 virus particle per embryonic cell. In situ expression of the lacZ marker gene was detected in only 0.06% of embryonic cells. These results lead us to conclude that only 6% of infected cells express efficiently the lacZ marker gene. This low level of expression could result from avian leukosis virus LTRs inhibition in chicken embryonic cells at an early stage of development. In spite of the low efficiency of infection, no evidence for tissue restrictive expression was observed. However, vector containing LTRs from RAV-2 virus allows preferential expression of provirus vector in neural tube tissue, whereas cardiac localization of the preferential expression was observed using vector containing the RAV-1 LTRs. The chronological analysis of the marker gene expression in terms of location of expression foci and sizes of these foci, lead us to hypothesize the putative regulation of retrovirus expression linked to embryonic development.

Abstract
Newcastle disease virus (NDV) is a paramyxovirus that bears two envelope glycoproteins at the virion surface. These proteins, fusion and hemagglutinin-neuraminidase (HN), are involved in the immune response against NDV infection. Recombinant cells constitutively expressing at their surface the HN protein from the velogenic Texas strain were generated by introducing the HN gene with a helper-free AEV-based vector. These recombinant cells were used to immunize chickens by various protocols, and birds were subsequently challenged with a lethal NDV injection. Both NDV protection and serologic response were observed.

Abstract
The Rous-associated virus 1 env gene, which encodes the envelope gp85 and gp37 glycoproteins, was isolated and inserted in place of the v-erbB oncogene into an avian erythroblastosis virus-based vector, carrying the neo resistance gene substituted for the v-erbA oncogene, to generate the pNEA recombinant vector. A helper-free virus stock of the pNEA vector was produced on an avian transcomplementing cell line and used to infect primary chicken embryo fibroblasts (CEFs) or quail QT6 cells. These infected cells, selected with G418 (CEF/NEA and QT6/NEA, respectively) were found to be resistant to superinfections with subgroup A retroviruses. The CEF/NEA preparations were used as a cell-associated antigen to inoculate adult chickens by the intravenous route compared with direct inoculations of NEA recombinant helper-free virus used as a cell-free antigen. Chickens injected with the cell-associated antigen (CEF/NEA) exhibited an immune response demonstrated by induction of high titers of neutralizing antibodies and were found to be protected against tumor production after Rous sarcoma virus A challenge. Conversely, no immune response and no protection against Rous sarcoma virus A challenge were observed in chickens directly inoculated with cell-free NEA recombinant virus or in sham-inoculated chickens.
