Tumor necrosis factor-α-inducible protein-2 (TNFAIP2) is a protein upregulated in cultured cells treated with tumor necrosis factor α (TNF), but its expression in normal and neoplastic tissues remains largely unknown. Here, we use standard immunohistochemical techniques to demonstrate that TNFAIP2 is normally expressed by follicular dendritic cells, interdigitating dendritic cells, and macropha...

Human B cells detect CpG motifs within microbial DNA via TLR9. Synthetic CpG oligodeoxynucleotides are currently being tested in clinical trials for the therapy of different types of B cell non-Hodgkin's lymphoma. However, there is only limited information on the CpG oligodeoxynucleotide sensitivity of primary malignant B cells of different non-Hodgkin's lymphoma entities. Here we found that mo...

The B-cell activation markers CXCL13, sCD23, sCD27, and sCD30 are associated with future lymphoma risk. However, a lack of information about the individual dynamics of marker-disease association hampers interpretation. In this study, we identified 170 individuals who had donated two prediagnostic blood samples before B-cell lymphoma diagnosis, along with 170 matched cancer-free controls from th...

abstract background involvement of lacrimal apparatus by non hodgkin lymphoma as a first manifestation is extremely rare and only three cases have been reported in children. the purpose of this report is to determine the clinical characteristic of patient with primary involvement of lacrimal apparatus with lymphoma. case presentation a 7-year-old girl with history of tearing, gradually progress...

oral cavity t-cell lymphoma occurs rarely. this case report describes a patient with such a tumor. the case was a 75 years old man presented with a painless swelling on his hard palate mucosa. he had suffered from nose- bleeding and nasal obstruction. pathology revealed the presence of a t-cell lymphoma tumor in the palate. though rare, the signs and symptoms of the case suggest that t-cell lym...

PURPOSE CMC-544 is a CD22-targeted immunoconjugate of calicheamicin and exerts a potent cytotoxic effect against CD22+ B-cell lymphoma. This study evaluated antitumor efficacy of CMC-544 against systemically disseminated B-cell lymphoma. EXPERIMENTAL DESIGN Scid mice received i.v. injections of CD22+ Ramos B-cell lymphoma cells for their systemic dissemination. CMC-544, G5/44, CD33-targeted C...

Histone methylation and demethylation regulate B-cell development, and their deregulation correlates with tumor chemoresistance in diffuse large B-cell lymphoma, limiting cure rates. Since histone methylation status correlates with disease aggressiveness and relapse, we investigated the therapeutic potential of inhibiting histone 3 Lys27 demethylase KDM6B, in vitro, using the small molecule inh...

We present a 52-year-old man who was diagnosed with B cell-derived angioimmunoblastic lymphoma. He was admitted with systemic, including mediastinal and para-aortic, lymphadenopathy, fever and skin itching. Histologically, his lymph nodes showed total obliteration of the normal architecture by a polymorphic infiltrate of large-sized lymphocytes with proliferation of arborizing small blood vesse...

We evaluated the expression of 10 adhesion molecules on peripheral blood tumor cells of 17 patients with chronic lymphocytic leukemia, 17 with mantle-cell lymphoma, and 13 with nodal or splenic marginal B-cell lymphoma, all in the leukemic phase and before the beginning of any therapy. The diagnosis of B-cell non-Hodgkin's lymphomas was based on cytological, histological, immunophenotypic, and ...

Immunotherapy with therapeutic idiotype vaccines offers promise for treatment of B-cell malignancies. However, identification of novel immunogenic lymphoma-associated antigens that are universally expressed is necessary to overcome the barriers of patient-specific idiotype vaccines. Here, we determined whether T-cell leukemia/lymphoma 1 (TCL1) oncoprotein encoded by the TCL1 gene could be a tar...
