Human T Lymphotropic Virus Type I (HTLV-I) Oncogenesis: Molecular Aspects of Virus and Host Interactions in Pathogenesis of Adult T cell Leukemia/Lymphoma (ATL)
The study of tumor viruses paves the way for understanding the mechanisms of virus pathogenesis, including those involved in establishing infection and dissemination in the host tumor affecting immune-compromised patients. The processes ranging from viral infection to progressing malignancy are slow and usually insufficient for establishment of transformed cells that develop cancer in only ...
متن کاملT Regulatory Cells Frequency During Maintenance Phase Chemotherapy for Pediatric Acute Lymphoblastic Leukemia
Background: Drugs used in cancer treatment specifically kill T regulatory cells. Objective: To determine different phenotypes of T regulatory cells during the maintenance phase chemotherapy for pediatric acute lymphoblastic leukemia (ALL). Materials: We evaluated the percentages of regulatory T cells by flow cytometry. Soluble CTLA-4 (sCTLA-4) ...
متن کاملInduction of T Regulatory Subsets from Naïve CD4+ T Cells after Exposure to Breast Cancer Adipose Derived Stem Cells
Background: Adipose derived stem cells (ASCs) provoke the accumulation and expansion of regulatory T cells, leading to the modulation of immune responses in tumor microenvironment. Objective: To assess the effect of tumoral ASCs on the trend of regulatory T cells differentiation. Methods: Peripheral blood naïve CD4+ T cells were co-cultured with ASCs derived from breast cancer or normal breast ...
متن کاملExpansion of CD4+CD25+FoxP3+ Regulatory T Cells in Chronic Hepatitis C Virus Infection
Background: Regulatory T cells (Tregs) have been involved in impaired immunity and may have a pivotal role in persistence of viral infections. Objective: To develop a simple and reliable in-house three color flow cytometery of peripheral blood to understand the role of HCV infection in the increase of Tregs. Methods: The level of naturally occurring CD4+CD25+FoxP3+ regulatory T cells (nTregs) i...
متن کاملP 56: Inhibitory Effects of Curcumin, a Regulator of CD4+ T Helper Cell, on HTLV-1-Associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP)
Human T-lymphotropic virus type I (HTLV-1) is an endemic virus in Iran and other regions that is associated with multiple diseases including adult T-cell leukemia/ lymphoma and a chronic debilitating neuroinflammatory disease, HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). HAM/TSP is seen in approximately 2% of HTLV-1-infected people with symptoms such as back pain, weakne...
