Surface Bound Immunoglobulins as a Cell Marker in Human Lymphoproliferative Diseases

Surface bound immunoglobulins as a cell marker in human lymphoproliferative diseases.

Enzyme analysis of lymphoproliferative diseases: a useful addition to cell surface phenotyping.

Lymphocytes from patients with acute and chronic T-cell malignancy or chronic T gamma lymphocytosis were characterized by studying the activity of three enzymes involved in purine metabolism and by determining the isoenzyme pattern of lactate dehydrogenase (LDH) in addition to analysis of surface marker expression with monoclonal antibodies. Four clinically different types of disease were disti...

Expression of cell-homologous genes of human herpesvirus-8 in human immunodeficiency virus-negative lymphoproliferative diseases.

Human herpesvirus-8 (HHV-8) genome encodes for genes homologous to human cellular genes such as interleukin-6 (IL-6), Cyclin-D, BCL-2, and IL-8 receptor (G-protein-coupled receptor [GCR]). We used reverse transcriptase-polymerase chain reaction to study the expression of these viral genes in lymphoproliferative disorders associated with HHV-8 infection. None of these genes was expressed in 1 ca...

Human herpesvirus 8 infection in patients with cutaneous lymphoproliferative diseases.

OBJECTIVE To investigate the prevalence of human herpesvirus 8 (HHV-8; Kaposi sarcoma-associated herpesvirus) infection in patients with lymphoproliferative skin diseases such as large-plaque parapsoriasis (LPP) and mycosis fungoides compared with inflammatory cutaneous conditions or healthy control subjects. DESIGN A survey study was undertaken in 123 subjects with various clinical condition...

Immune thrombocytopenia in lymphoproliferative diseases.

We have studied the thrombocytopenia of lymphoproliferative disorders using a measurement of membrane-bound IgG by an antiglobulin consumption assay. Nine patients with chronic lymphocytic leukemia (CLL) and thrombocytopenia had increased membrane-bound IgG. Two patients with non-Hodgkins lymphoma and 1 patient with Hodgkins disease also had thrombocytopenia and increased membrane-bound IgG. Fi...
