Follicular lymphoma (FL) is a low-grade lymphoma that typically lacks CD5 antigen expression. We report 3 cases of FL with unusual expression of CD5. All cases showed histologic features of FL, including effaced nodal architecture, follicular growth pattern, and a spectrum of grades from 1 to 3 using World Health Organization criteria. In flow cytometric studies, all 3 cases showed a light chai...
The CD5 lymphocyte surface glycoprotein is a coreceptor involved in the modulation of Ag-specific receptor-mediated activation and differentiation signals. The molecular basis for its modulatory properties is not yet well understood. In the present study we describe early biochemical events triggered by CD5 stimulation, which include the phosphatidylcholine-specific phospholipase C (PC-PLC)-dep...
The pathogenesis of Epstein-Barr virus-positive (EBV+) mature T-cell and natural killer (NK)-cell neoplasms is challenging to understand. The clinical features are diverse, with no typical manifestation. Therefore, it is important to analyze the association of the clinical characteristics and prognoses of patients with various factors associated with EBV+ T/NK-cell neoplasms, particularly extra...
Despite the relatively early reconstitution of blood B-lymphocyte counts observed in patients treated with bone marrow transplantation (BMT), these patients undergo a prolonged phase of humoral immunodeficiency. Adhesion molecules perform relevant functions in many cell types. The present study examines the expression of several adhesion molecules on human B lymphocytes newly formed after BMT. ...
CD5 is a lymphocyte surface coreceptor of still incompletely understood function. Currently available information indicates that CD5 participates not only in cell-to-cell immune interactions through still poorly defined endogenous ligands expressed on hemopoietic and nonhemopoietic cells but also in recognition of exogenous and highly conserved microbial structures such as fungal β-glucans. Pre...
Introduction: The diagnosis of chronic lymphocytic leukemia/ small lymphoma (CLL/SLL), which also includes atypical forms, can be very difficult. aim this study is to compare immunohistochemical (IHC) and flow cytometric (FC) immunophenotyping methods in the CLL/SLL, most common mature B-cell leukemia/lymphoma adults, bone marrow biopsy. In these two methods, it determine minimum panels that di...
