Transgenic expression of interleukin 7 restores T cell populations in nude mice
The thymic lesion of the nude mouse causes a profound block in T cell development. The failure of most T cells to mature in nude mice is likely to reflect a requirement for signals elaborated in the normal thymus. Interleukin 7 (IL-7), a lymphokine that is normally expressed in the thymus and has been implicated in T cell maturation, might be central to this process. To test this possibility, w...
متن کاملTreatment with Interleukin-7 Restores Host Defense against Pneumocystis in CD4+ T-Lymphocyte-Depleted Mice.
Pneumocystis pneumonia (PCP) is a major cause of morbidity and mortality in patients with HIV infection. CD4(+) T lymphocytes are critical for host defense against this infection, but in the absence of CD4(+) T lymphocytes, CD8(+) T lymphocytes may provide limited host defense. The cytokine interleukin-7 (IL-7) functions to enhance lymphocyte proliferation, survival, and recruitment of immune c...
متن کاملEffect of hesperetin on interleukin-8 gene expression in MCF-7 cell line: Short Communication
Breast cancer is recognized as the most common cause of cancer deaths in women. So far, no definite treatment has been identified there is no certain cure for breast cancer. The Ooverexpression of interleukin-8 is associated with increased tumor growth and breast cancer metastasis. Hesperetin is a flavonone sub-group of flavonoids that is abundantly found in citrus fruits, including lemons and ...
متن کاملInterleukin 17, a T-cell-derived cytokine, promotes tumorigenicity of human cervical tumors in nude mice.
Interleukin (IL) 17 is a proinflammatory cytokine secreted mainly by activated human memory CD4 T cells that induces IL-6, IL-8, and nitric oxide. Because IL-6 and IL-8 have been implicated in the pathogenesis of cervical cancer, we investigated the action of IL-17 on human cervical tumor cell lines in vitro and in vivo. We showed that in vitro, IL-17 increases IL-6 and IL-8 secretion by cervic...
متن کاملCutaneous lymphoproliferation and lymphomas in interleukin 7 transgenic mice
To investigate the role of interleukin 7 (IL-7) in the development of the lymphoid system, we have generated two lines of transgenic mice carrying an IL-7 cDNA fused to an immunoglobulin heavy chain promoter and enhancer. This transgene is expressed in the bone marrow, lymph nodes, spleen, thymus, and skin provoking a perturbation of T cell development characterized by a marked reduction of CD4...
