This study is an investigational approach that uses immune cells, called "T cells", to kill leukemia. These T cells are removed from blood, modified in a laboratory, and then put back in the body. T cells fight infections and can also kill cancer cells in some cases. However, right now T cells are unable to kill the cancer cells. For this reason we will put a gene in the T cells that allows them to recognize and kill the leukemia cells. This gene will be put in the T cells by a weakened virus. The gene will produce a protein in the T cells that helps the T cells recognize the leukemia cells and possibly kill them. The doctors have found that T cells modified in this way can cure an ALL-like cancer in mice.
The main goal of this study is to find a safe dose of modified T cells to give to a patient with ALL. This will be done in a "phase I trial." The T cell dose will increase for each new group of patients as the trial progresses. If too many serious side effects are seen with a certain dose, no one will be treated with a higher dose, and some additional patients may be treated with a lower dose to make sure that this dose is safe. The patient will also receive the chemotherapy drug cyclophosphamide before the T cells. Cyclophosphamide is a chemotherapy normally used in patients with leukemia. Cyclophosphamide is given to reduce leukemia and to allow the T cells to live longer.

This study is for patients that have chronic lymphocytic leukemia (CLL). This research study aims to determine the safety and dosage of special cells that may make the patients own immune ...
This is a phase I study which will test the safety of different doses of the patients own immune cells which have been changed to help recognize and destroy the cancer cells. The investiga...
Leukemia is characterized as a kind of malignant clonal disease in hematological stem cells. The study showed an abnormal level of DNA methylation in leukemia cells, which further led to an abnormal e...
IL15 and IL7 are two cytokines essential for T cell development and homeostasis. In order to improve the antitumor activity by Newcastle Disease Virus (NDV)-modified tumor vaccine, we generated a reco...
CD19-targeted chimeric-antigen receptor-modified T-cells (CAR-T) are promising in the treatment of refractory B-lymphoblastic leukemia (B-ALL). Minimal residual disease (MRD) detection by multicolor f...
Gene targeting, i.e., the disruption of a specific gene via homologous recombination, is one of the key techniques to study gene function. However, researchers have faced the difficulty that, in human...
Chronic Lymphocytic Leukemia B cells (CLL) are malignant cells which retain at least some functions of normal B cells. Paramount amongst the latter is that when such cells are appropriately stimulated...
The introduction of new genes into cells for the purpose of treating disease by restoring or adding gene expression. Techniques include insertion of retroviral vectors, transfection, homologous recombination, and injection of new genes into the nuclei of single cell embryos. The entire gene therapy process may consist of multiple steps. The new genes may be introduced into proliferating cells in vivo (e.g., bone marrow) or in vitro (e.g., fibroblast cultures) and the modified cells transferred to the site where the gene expression is required. Gene therapy may be particularly useful for treating enzyme deficiency diseases, hemoglobinopathies, and leukemias and may also prove useful in restoring drug sensitivity, particularly for leukemia.
Radiotherapy where cytotoxic radionuclides are linked to antibodies in order to deliver toxins directly to tumor targets. Therapy with targeted radiation rather than antibody-targeted toxins (IMMUNOTOXINS) has the advantage that adjacent tumor cells, which lack the appropriate antigenic determinants, can be destroyed by radiation cross-fire. Radioimmunotherapy is sometimes called targeted radiotherapy, but this latter term can also refer to radionuclides linked to non-immune molecules (see RADIOTHERAPY).
Immunized T-lymphocytes which can directly destroy appropriate target cells. These cytotoxic lymphocytes may be generated in vitro in mixed lymphocyte cultures (MLC), in vivo during a graft-versus-host (GVH) reaction, or after immunization with an allograft, tumor cell or virally transformed or chemically modified target cell. The lytic phenomenon is sometimes referred to as cell-mediated lympholysis (CML). These CD8-positive cells are distinct from NATURAL KILLER CELLS and NATURAL KILLER T-CELLS. There are two effector phenotypes: TC1 and TC2.
A replication-defective murine sarcoma virus (SARCOMA VIRUSES, MURINE) capable of transforming mouse lymphoid cells and producing erythroid leukemia after superinfection with murine leukemia viruses (LEUKEMIA VIRUS, MURINE). It has also been found to transform cultured human fibroblasts, rat liver epithelial cells, and rat adrenocortical cells.
Form of adoptive transfer where cells with antitumor activity are transferred to the tumor-bearing host in order to mediate tumor regression. The lymphoid cells commonly used are lymphokine-activated killer (LAK) cells and tumor-infiltrating lymphocytes (TIL). This is usually considered a form of passive immunotherapy.

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
