Cytogenetic and immunoglobulin markers of human leukemic B-cell lines.

Expression Pattern of Interferon-γ in Human Leukemic T Cell Lines Following Treatment with Phytoheamagglutinin, phorbol myristate acetate and Lipopolysaccharide

Background: As a T helper type 1 (Th1) derived cytokine, Interferon gamma (IFN-γ) is an important regulator of inflammatory immune responses. Furthermore, IFN-γ plays an essential role in defense against tumors and intracellular pathogens. This study was designed to assess the pattern of IFN-γ production in human leukemic (Jurkat and Molt-4) T cell lines in vitro. Methods: Ju...

Patterns of Gelatinase-B Expression in Leukemic Cell Lines

Assessment of Cytotoxicity of Dimethyl Sulfoxide in Human Hematopoietic Tumor Cell Lines

Background: Dimethyl Sulfoxide (DMSO) is a solvent most broadly used as a cryopreservative agent. Antitumor effects of DMSO is a recently recognized phenomenon. In this study, cytotoxic effects of DMSO on human monocytes and T leukemic cell lines has been investigated in vitro. Methods: Human leukemic T cells (Molt-4 and Jurkat) and monocytes (U937 and THP1) were cultured in complete RPMI medi...

Comparative cytogenetic studies of normal and leukemic lymphoblastoid cell lines during the course of their establishment.

A comparative chromosomal analysis was made of 10 human lymphoblastoid cell lines, four of which originated from normal donor lymphocytes and six of which were from leukemic peripheral blood. For comparison of lymphoblastoid cells with respect to their normal or leukemic origin, cytogenetic studies have been carried out regularly since the beginning of the culture during more than 3 years. Samp...

Profile of interleukin-2 production in human mononuclear cells and T-cell lines

Introduction: Interleukin-2 (IL-2) as a T helper type 1 (Th1) cytokine has an important role Background and Objective: Interleukin-2 (IL-2) as a T helper type 1 (Th1) cytokine has an important role in activation, growth and differentiation of several immune cells. Moreover IL-2 is known as a pro-inflammatory and anti-tumoral cytokine. In addition deysregulation of IL-2 in some diseases such as ...
