TLDR
In this article, a method for producing high-titer, helper-free infectious retroviruses is disclosed which employs a novel strategy that uses transient transfection of new retroviral producer cell lines, ecotropic line BOSC 23 and amphotropic line CAK 8.Abstract:
A method for producing high-titer, helper-free infectious retroviruses is disclosed which employs a novel strategy that uses transient transfection of new retroviral producer cell lines, ecotropic line BOSC 23 and amphotropic line CAK 8, both of which cell lines and their precursor cell lines are disclosed. Because of the advantages over stable packaging cell lines, the BOSC 23 and CAK 8 transient transfection systems greatly facilitate and extend the use of helper-free retroviral vectors. The cell lines and corresponding methods possess wide application in both the medical and biotechnical fields, including gene therapy. These potential applications are disclosed and illustrated.read more

Ectopic Human Telomerase Catalytic Subunit Expression Maintains Telomere Length But Is Not Sufficient for CD8+ T Lymphocyte Immortalization
Marco Migliaccio,Mario Amacker,Tom Just,Patrick Reichenbach,Danila Valmori,Jean-Charles Cerottini,Pedro Romero,Markus Nabholz +7 more
TL;DR: It is indicated that hTERT may be required but is not sufficient to immortalize human T lymphocytes, and the content of total telomere repeats in individual cells is found to be higher than that observed in freshly isolated normal CD8+ lymphocytes.

Antibody-antigen-adjuvant conjugates enable co-delivery of antigen and adjuvant to dendritic cells in cis but only have partial targeting specificity.

TL;DR: In this study, the assembly and characterization of conjugates consisting of DEC205-specific antibody, the model antigen ovalbumin (OVA) and CpG oligodeoxynucleotides (ODN) are reported on and it is revealed that antibody-antigen-adjuvant conjugating are superior to antibody-free antigen-advuvant conjugal responses and efficiently induce anti-tumour immunity in the murine B16 pseudo-metastasis model.

Growth inhibition and apoptosis due to restoration of E2A activity in T cell acute lymphoblastic leukemia cells
TL;DR: In the JurKat T cell line, originally derived from a patient with T-ALL, the Jurkat cells underwent growth arrest and subsequently apoptosis, thus supporting the inhibition model and suggesting that E2A loss may contribute to leukemic progression.

Domains of axin and disheveled required for interaction and function in wnt signaling.
Martin A. Julius,B. Schelbert,Wei Hsu,E. Fitzpatrick,Eek-hoon Jho,François Fagotto,Frank Costantini,Jan Kitajewski +7 more
TL;DR: A mutational and binding analysis of the murine Axin and Disheveled proteins found that the DIX domain of Dishe Veled is critical for association with Axin in vivo and for DisheVELed activity.

The Immunosuppressant Rapamycin Represses Human Immunodeficiency Virus Type 1 Replication
TL;DR: Northern blot analysis confirmed that this compound is selectively targeting HIV-1 mRNA synthesis, and the observed effect of rapamycin on HIV- 1 replication seems to be independent of the virus-specific transactivating Tat protein.

Characteristics of a Human Cell Line Transformed by DNA from Human Adenovirus Type 5
TL;DR: Human embryonic kidney cells have been transformed by exposing cells to sheared fragments of adenovirus type 5 DNA, and the transformed cells exhibited many of the characteristics of transformation including the elaboration of a virus-specific tumour antigen.

Vaccination with Irradiated Tumor Cells Engineered to Secrete Murine Granulocyte-Macrophage Colony-Stimulating Factor Stimulates Potent, Specific, and Long-Lasting Anti-Tumor Immunity

TL;DR: The results have important implications for the clinical use of genetically modified tumor cells as therapeutic cancer vaccines and the levels of anti-tumor immunity reported previously in cytokine gene transfer studies involving live, transduced cells could be achieved through the use of irradiated cells alone.

Induction of chronic myelogenous leukemia in mice by the P210bcr/abl gene of the Philadelphia chromosome
TL;DR: It is demonstrated that P210bcr/abl expression can induce chronic myelogenous leukemia and retrovirus-mediated expression of the protein provides a murine model system for further analysis of the disease.

The Basic Science of Gene Therapy
TL;DR: A large number of key technical issues need to be resolved before gene therapy can be safely and effectively applied in the clinic, and future technological developments will be critical for the successful practice of gene therapy.

Improved Retroviral Vectors for Gene Transfer and Expression
A D Miller,G J Rosman +1 more
TL;DR: A set of murine retrovirus-based vectors that include unique cloning sites for insertion of cDNAs such that the cDNA can be driven by either the retroviral long terminal repeat, the immediate early promoter of human cytomegalovirus, or the simian virus 40 early promoter are described.
