Lymphocyte Subpopulations in Chronic Lymphocytic Leukemia Patients Using a Clonogenic Agar Technique and Monoclonal Antibodies
نویسنده
چکیده
Peripheral blood lymphocytes from normal donors and patients with chronic lymphocytic leukemia. B-cell type. were purified into T. helper T. and suppressor T lymphocytes by fluorescence-activated cell sorting using OKT3. 0KT4. and 0KT8 monoclonal antibodies. The maximum response of the purified subpopulations to stimulation by phytohemagglutinin (PHA) was determined by measuring the production of colonies when the stimulated cells were

متن کاملMonoclonal and Polyclonal Antibodies Specific to Human Fibromodulin
Background: The unique expression of fibromodulin (FMOD) in patients with chronic lymphocytic leukemia (CLL) has been previously reported. Detecting FMOD in CLL patients using specific anti-FMOD mAbs might provide a promising method in detection, monitoring, and prognosis of CLL. Objectives: In this study, we aimed for producing specific antibodies agains...
متن کاملGPI-Anchored Fibromodulin as a Novel Target in Chronic Lymphocytic Leukemia: Diagnostic and Therapeutic Implications
Background: We have previously reported the aberrant expression of Fibromodulin (FMOD) in patients with chronic lymphocytic leukemia (CLL). Although FMOD has been considered as a cytoplasmic or secretory protein, we discovered the cell surface expression of FMOD in leukemic B cells via anchoring with glycosylphosphatidylinositol (GPI). Objective: To evaluate FM...
متن کاملImmunologic classification of lymphocytic leukemias based on monoclonal antibody-defined cell surface antigens.
A panel of monoclonal antibodies reactive with normal lymphocyte subsets was used to classify cases of lymphocytic leukemia on the basis of cell surface antigen expression. The antibodies employed were commercially available and included a common framework HLA-DR antibody, two pan-T antibodies (Leu-1 and OKT-3), and antibodies defining cytotoxic/suppressor (Leu-2 and OKT-8) and helper/inducer (...
متن کاملMurine monoclonal antibody therapy in two patients with chronic lymphocytic leukemia.
We infused the murine monoclonal antibody T101 into two patients with advanced refractory chronic lymphocytic leukemia (CLL) after confirming its reactivity with their CLL cells. One patient received doses of 1, 3, and 12 mg; the second patient received 10 mg. Antibody was delivered over 10--15 min. The major observations were: (1) T101 murine monoclonal antibody did bind to cells with T65 surf...
