AIM To Study the interaction of macrophage colony-stimulating factor (M-CSF) and interleukin-10 (IL-10) in productions of IL-12 and IL-18 and expressions of CD14, CD23, and CD64 by human monocytes. METHODS Purified adherent human monocytes were cultured with M-CSF or IL-10 alone, or with M-CSF+IL-10 and 2-3d later, the culture supernatants and cells were separated and collected. IL-12P40 and ...
AMAÇ: İmmünofenotipleme, B hücre malignitesi teşhisi için kritik öneme sahiptir. Bu çalışmada klinik ve morfolojik olarak Kronik Lenfositik Lösemi (KLL) tanısı almış vakalarımızda akım sitometri yöntemi ile yüzey antijen ekspresyon yüzdelerini yoğunluklarını değerlendirmeyi amaçladık.GEREÇ VE YÖNTEM: 33 KLL hastasının (12 kadın / 21 erkek) periferik venöz kanına ait sonuçları geriye dönük incel...
Different leukemias express on their plasma membranes particular subsets of the 247 defined cluster of differentiation (CD) antigens, which may resemble those of precursor cells along the lineages of differentiation to mature myeloid and lymphoid leukocytes. The extent of use of CD antigen expression (immunophenotyping) for identification of leukemias has been constrained by the technique used,...
The serum levels of soluble intercellular adhesion molecule 1 (ICAM-1) were significantly elevated (P < .001) in patients with chronic B-lymphocytic leukemia (B-CLL, n = 113) compared with healthy controls (n = 31). sICAM-1 levels in B-CLL were positively correlated to the tumor mass as reflected by the modified Rai and the Binet staging systems, lymphocyte counts, and isolated spleno/hepatomeg...
A significant impairment in understanding the biology and advancing therapeutics for Waldenstrom's macroglobulinemia (WM) has been the lack of a representative cell line and animal model. We, therefore, report on the establishment of the BCWM.1 cell line, which was derived from the long-term culture of CD19(+) selected bone marrow lymphoplasmacytic cells isolated from an untreated patient with ...
Soluble CD23 (sCD23) has multiple IgE-independent biological activities. In the present study, we examined the regulatory effect of sCD23 on cytokine production by human peripheral blood mononuclear cells (PBMC). We show that sCD23 enhances by about 80-fold the interleukin 2 (IL-2)-induced interferon gamma (IFN-gamma) production and by about 10-fold the response to IL-12. This potentiating acti...
The typical cases have faint surface IgM/IgD expression with k/l light chain restriction; pan-B antigens are positive, but CD22 expression is weak. CD5 and CD23 test positive, whereas CD10 and FMC7 are negative; the expression of CD11c and CD25 is variable; the postulated normal counterpart is a peripheral CD5+/CD23+ B cell; based on the presence/absence of the CD38 antigen, a distinction was s...
Background Inflammatory bowel diseases (IBD) are chronic inflammatory diseases of the gastrointestinal tract, which clinically present as one of two disorders, Crohn’s disease (CD) and ulcerative colitis (UC). The CD23 is a multifunctional molecule expressed on various cells. It is know as the low-affinity receptor for the Fc portion of IgE. It expression at the cell surface of phagocytic cells...
