PURPOSE In this study we aimed to compare the flow cytometry (FC) results of patients with B cell lymphoma, T cell lymphoma, Hodgkin's lymphoma, granulomatous inflammation and reactive lymph node and investigate the role of FC in malignant or non malignant conditions. METHODS Ninety patients were divided into 5 groups according to histopathology results. Patients were compared according to cy...
Preeclampsia is a devastating pregnancy-associated disorder affecting 5% to 8% of pregnant women worldwide. It emerges as an autoimmune-driven disease, and, among others, the autoantibodies against angiotensin type 1 receptor II have been proposed to account for preeclampsia symptoms. Despite much attention focused on describing autoantibodies associated with preeclampsia, there is no clue conc...
Infection of genetically susceptible mice with the LP-BM5 mixture of murine leukemia viruses including an etiologic defective virus (BM5def) causes an immunodeficiency syndrome called murine AIDS (MAIDS). The disease is characterized by interactions between B cells and CD4(+) T cells resulting in polyclonal activation of both cell types. It is known that BM5def is expressed at highest levels in...
Background: Bispecific antibodies represent an important class of mAbs, with great therapeutic potentials due to their ability to target simultaneously two distinct epitopes. The generation of functional bispecific antibodies with the highest possible yields is particularly critical for the production of these compounds on industrial scales. Anti- CD3 × CD19 bsAb is a bispecific T-cell engager ...
Malignant stem cells in childhood ALL: the debate continues! Recently, Cox et al 1 described that only acute lymphoblastic leukemia (ALL) blasts with a CD19 Ϫ CD133 ϩ immune-phenotype are able to propagate human leukemia in immune-deficient nonobese diabetic severe combined immunodeficiency (NOD/scid) mice. We welcome this contribution to the rapidly evolving debate on leukemic stem cells. Publ...
The ability to selectively target liposomal anticancer drugs via specific ligands against antigens expressed on malignant cells could improve the therapeutic effectiveness of the liposomal preparations as well as reduce adverse side effects associated with chemotherapy. Long-circulating for mulations of liposomes containing lipid derivatives of poly(ethyleneglycol) [sterically stabilized liposo...
CD19 is a pan B-cell surface receptor expressed from pro-B-cell development until its down-regulation during terminal differentiation into plasma cells. CD19 represents an attractive immunotherapy target for cancers of lymphoid origin due to its high expression levels on the vast majority of non-Hodgkin's lymphomas and some leukemias. A humanized anti-CD19 antibody with an engineered Fc domain ...
Introduction. Lymphocytic infiltration and specific lymphocytes subsets may play important roles in papillary thyroid carcinoma (PTC) progression and prognosis. In this study, we try to understand the influence of (131)I radioablation on the important lymphocytes subtypes of regulatory T and B cells (Tregs and Bregs). Methods. Peripheral blood mononuclear cells from 30 PTC patients before and a...
The pan B-cell surface antigen CD19 is an attractive target for therapeutic monoclonal antibody (mAb) approaches. We have generated a new afucosylated anti-human (hu)CD19 mAb, MEDI-551, with increased affinity to human FcγRIIIA and mouse FcγRIV and enhanced antibody-dependent cellular cytotoxicity (ADCC). During in vitro ADCC assays with B-cell lines, MEDI-551 is effective at much lower mAb con...
Immunoglobulin D (IgD) is a surface immunoglobulin that is expressed as either membrane IgD (mIgD) or secreted IgD (sIgD). Researchers have shown that sIgD is often elevated in patients with autoimmune diseases. The possible roles of sIgD on the function of peripheral blood mononuclear cells (PBMCs) in rheumatoid arthritis (RA) are still unclear. In this study, we compared the expression of sIg...
