Leukotriene B4 plays a pivotal role in CD40-dependent activation of chronic B lymphocytic leukemia cells.
Biosynthesis of leukotrienes (LTs) occurs in human myeloid cells and B lymphocytes. However, the function of leukotrienes in B lymphocytes is unclear. Here, we report that B-cell chronic lymphocytic leukemia (B-CLL) cells produce leukotriene B(4), and that specific leukotriene biosynthesis inhibitors counteracted CD40-dependent activation of B-CLL cells. Studies on the expression of the high-af...
متن کاملAnalysis of HLA-G Gene Expression in B-Lymphocytes from Chronic Lymphocytic Leukemia Patients
The human leukocyte antigen G (HLA-G) molecule exhibits limited tissue distribution, low polymorphism and alternative splicings that generate seven HLA-G isoforms. HLA-G exerts multiple immunoregulatory functions. Recent studies indicate an ectopic up-regulation in tumor cells that may favor their escape from anti-tumor immune responses. This study it is an effort to clarify the presence of HLA...
متن کاملChronic lymphocytic leukemia, biology, new diagnosis and treatment: review article
Chronic lymphocytic leukemia (CLL) is a malignancy of B CD5+cells and is the most common type of leukemia in adults. The disease is more common in men over 50 years in western countries. CLL is associated with defective apoptosis in B cells. CLL was traditionally regarded as a disease that occurs before naïve B cells meet the antigen in the lymph nodes. Laboratory diagnosis requires white blood...
متن کاملComparison Cytotoxic Effects of Mangifera Indica L. and Juglans Regia Aqueous Extract on Human Chronic Lymphocytic Leukemia
Natural products isolated from plant sources are well known for their pharmacological potential in diversity of disease treatments such as inflammatory or cancer conditions. Mango (Mangifera indica L.) and Juglans regia are thought to be rich of functional phytochemicals. To elucidate the anticancer activity of Juglans regia (JR) and Mangifera indica L (MI) aqueous extract were investigated on ...
