Waldenstrom macroglobulinemia (WM) is a B-cell lymphoproliferative disorder associated with bone marrow involvement of lymphoplasmacytic lymphoma (LPL) and an IgM monoclonal gammopathy. Generally B-lymphocytes in LPL do not express CD5 that is important for differential diagnosis of B-cell lymphoproliferative disorders. In WM, various renal diseases and type I cryoglobulinemia are well describe...
After the addition of a CD3 monoclonal antibody to peripheral T cells that have been previously stimulated with phytohemagglutinin, inositol phosphates are produced at a rapid rate for 2 min and at a much slower rate thereafter. Stimulation of CD5 allows CD3-mediated production of inositol phosphates to be sustained at a brisk rate for greater than 20 min and augments the initial CD3-mediated i...
De novo CD5-positive diffuse large B-cell lymphoma (CD5(+) DLBCL) accounts for approximately 10% of DLBCL, and is usually associated with aggressive clinical course. We report a case of CD5(+) DLBCL with primary involvement of the spleen and liver, and no distinct mass lesions or lymphadenopathy. The patient had stage IV disease with bone marrow involvement by lymphoma. The lymphoma cells showe...
We report a case of de novo diffuse large B-cell lymphoma (DLBCL) in leukemic phase, positive for both CD5 and CD13. Morphologic evaluation, flow cytometric immunophenotyping, karyotyping and polymerase chain reaction studies were performed. Neoplastic lymphocytes appeared as blast-like cells, positive for CD19, CD20, CD5, CD13, CD79a, HLADR, and with restriction for surface immunoglobulin K li...
B cell chronic lymphocytic leukemia (CLL) is the malignant, monoclonal equivalent of a human CD5+ B cell. Previous studies have shown that the VH and VL genes rearranged and/or expressed in CLL have few and apparently random mutations. However, in this study, we have found that the rearranged VH251 gene, one of the three-membered VH5 family, has extensive and selective mutations in B-CLL cells....
BACKGROUND The exact pathogenesis of autism is still unknown. Both thyroid hormones and 25(OH)D are important for brain development, in addition to CD5; all have immunomodulatory actions by which their dysregulation may have a potential role in autism pathogenesis. OBJECTIVES The objectives of this study were to assess the thyroid profile, serum 25(OH)D levels and CD5 expression levels among ...
سابقه و هدف: هدف از این مطالعه، بررسی اثر داروی فلودارابین- سیکلوفسفامید در درمان بیماران ایرانی مبتلا به لوسمی لنفوسیتی مزمن نوع- B میباشد. مواد و روش ها: در این مطالعه که از اردیبهشت 1390 تا خرداد 1391 انجام شد، 20 بیمار مبتلا به لوسمی لنفوسیتی مزمن (میانگین سنی 63 سال) وارد مطالعه شدند و تحت درمان با رژیم استاندارد دارویی فلودارابین (25 میلیگرم) و سیکلوفسفامید (250 میلیگرم) به صورت ...
In this issue of the Journal, Baseggio et al. 1 report on a series of 24 patients with CD5-positive, t(11;14)-negative splenic marginal zone lymphoma (SMZL) diagnosed by means of cytology and flow cytometry of peripheral blood. All the patients were splenectomized at diagnosis or during follow-up and, consequently, spleen specimens were available for histological examination in all cases. The b...
