Project description:Large granular lymphocyte leukemia (LGLL) is a rare lymphoproliferative malignancy caused by clonal expansion of granular lymphocytes. Two subgroups, (cytotoxic) T-cell LGLL and natural killer (NK) cell LGLL, are defined based on their cellular origin and expression of characteristic surface molecules. In this study, we performed a comparative proteome profiling of isolated extracellular vesicles (EV) from the T-LGLL cell line MOTN-1 and the NK-LGLL line NKL.
Project description:We used microarrays to expression profile peripheral blood mononuclear cells (PBMCs) from LGL leukemia patients and control subjects to identify survival pathways that render leukemic LGL resistant to activation induced cell death. Keywords: granular lymphocyte leukemia, PBMC
Project description:The bone marrow microenvironment in Large Granular Lymphocyte Leukemia (LGLL) patients has been unexplored for it’s role in the development of cytopenias, which lead to complications resulting in the most prominent causes of morbidity and mortality. We used microarrays on primary mesenchymal stem cell (MSC) cultures isolated from bone marrow aspirates from LGLL patients to identify genetic programs that may lead to the observed profibrotic and extrinsically senescent phenotype.
Project description:This study uses a drug called dasatinib to produce an anti-cancer effect called large granular lymphocyte cellular expansion. Large granular lymphocytes are blood cells known as natural killer cells that remove cancer cells. Researchers think that dasatinib may cause large granular lymphocyte expansion to happen in patients who have received a blood stem cell transplant (SCT) between 3 to 15 months after the SCT. In this research study, researchers want to find how well dasatinib can be tolerated, the best dose to take of dasatinib and how to estimate how often large granular lymphocytic cellular expansion happens at the best dose of dasatinib.
