1. A SNP in 5′ untranslated region of CD40 gene is associated with an increased risk of ischemic stroke in a Chinese population: a case-control study
Abstract Cluster of differentiation 40 (CD40), the receptor for CD154, is a member of the tumor necrosis factor (TNF) receptor superfamily. Several studies have been conducted to investigate the effect of the CD40 rs1883832 polymorphism on atherosclerotic disease in different population; however, inconsistent results were obtained. In this study, we investig

2. Co-culture of apoptotic breast cancer cells with immature dendritic cells: a novel approach for DC-based vaccination in breast cancer
A dendritic cell (DC)-based vaccine strategy could reduce the risk of recurrence and improve the survival of breast cancer patients. However, while therapy-induced apoptosis of hepatocellular and colorectal carcinoma cells can enhance maturation and antigen presentation of DCs, whether this effect occurs in breast cancer is currently unknown. In the present

3. Avaliação do CA-125 e do CD-23 solúvel em pacientes com endometriose pélvica / Evaluation of CA-125 and soluble CD-23 in patients with pelvic endometriosis
Objetivo: Avaliar as concentrações séricas do CA-125 e do CD-23 solúvel, durante dois períodos do ciclo menstrual (primeiro, segundo ou terceiro dia e o sétimo, oitavo ou nono dia), correlacionando-as a queixas clínicas, local de doença, estadiamento pela American Society for Reproductive Medicine e classificação histológica da endometriose pélvi

4. Estudos funcionais e estruturais da proteína recombinante humana UBE2G2 (Ubiquitin-conjugating enzyme E2G2).
The ubiquitin system represents a selective mechanism for intracellular proteolysis in eukaryotic cells that involves the sequential activity of three enzymes, E1 (Ubiquitin activating enzyme), E2 (Ubiquitin-conjugating enzyme), and E3 (Ubiquitin-protein ligase). The identification of these proteins and their targets as well as structural data is essential t

5. Epidermal keratinocyte-derived basophil promoting activity. Role of interleukin 3 and soluble CD23.
Human epidermal keratinocytes (EK) secrete factors able to sustain the proliferation of early myeloid cells and, in particular, the generation of basophils. This activity was previously attributed to IL-3, although no definitive in situ demonstration of this cytokine was provided. In regard to the possible physiological relevance of these data, we investigat

6. In Vitro Expansion of T-Cell-Receptor Vα2.3+ CD4+ T Lymphocytes in HLA-DR17(3), DQ2+ Individuals upon Stimulation with Mycobacterium tuberculosis
The T-cell receptor (TCR) Vα/β gene product expression upon in vitro stimulation with mycobacteria was investigated to assess whether T-cell proliferation was associated with any specific TCR V gene usage. T-cell-enriched populations from peripheral blood of Mycobacterium bovis BCG-vaccinated healthy blood donors were stimulated in vitro with live or kille

7. Epstein-Barr virus (EBV)-containing nasopharyngeal carcinoma cells express the B-cell activation antigen blast2/CD23 and low levels of the EBV receptor CR2.
Anaplastic nasopharyngeal carcinoma (NPC) cells invariably harbor the Epstein-Barr virus (EBV) genome, an association that is unique among human virus-associated cancers. Although EBV is able to replicate in epithelial cells, results with expression of the EBV receptor (complement receptor type 2 [CR2]; also called CD21) in normal and malignant epithelial ce

8. ICAM-1, soluble-CD23, and interleukin-10 concentrations in serum in renal-transplant recipients with Epstein-Barr virus reactivation.
Primary and reactivated Epstein-Barr virus (EBV) infections after organ transplantation are associated with the development of posttransplant lymphoproliferative malignancies. Since viral reactivation frequently stays asymptomatic, early diagnosis and treatment are challenges during posttransplant patient monitoring. Both soluble-CD23 (sCD23) and intercellul

9. Cytokine effects of CD23 are mediated by an epitope distinct from the IgE binding site.
Human CD23 and its soluble forms (sCD23) display various biological activities, in addition to their IgE binding function (IgE/BF). The IgE binding domain was recently mapped to residues between Cys163 and Cys282 but its involvement in IgE-independent, CD23 functions remains unknown. In order to clarify this point, a series of N-terminal, C-terminal and inte

10. Immunohistochemical demonstration of CD23 expression on lymphocytes in rheumatoid synovitis.
The leucocyte antigen CD23 is expressed by B lymphocytes following activation by a number of stimuli and functions as an IgE receptor, and in its soluble form, as a putative B cell growth factor. The expression of CD23 on the surface of lymphocytes in paraffin wax sections of synovial biopsy specimens was studied using a novel mouse monoclonal antibody, BU38

11. B-cell activation by crosslinking of surface IgM or ligation of CD40 involves alternative signal pathways and results in different B-cell phenotypes.
Treatment of small resting B cells with soluble F(ab')2 fragments of anti-IgM, an analogue of T-independent type 2 antigens, induced activation characterized by proliferation and the expression of surface CD5. In contrast, B cells induced to proliferate in response to thymus-dependent inductive signals provided by either fixed activated T-helper 2 cells or s

12. In vitro inhibition of the infectivity and replication of human immunodeficiency virus type 1 by combination of antiretroviral 2',3'-dideoxynucleosides and virus-binding inhibitors.
We tested the in vitro inhibitory activities of three 2',3'-dideoxynucleosides and two inhibitors of viral binding in combinations against the infectivity and cytopathic effect of human immunodeficiency virus type 1. 3'-Azido-2',3'-dideoxythymidine, 2',3'-dideoxyinosine, or 2',3'-dideoxycytidine, combined with recombinant soluble CD4 (sCD4), brought about sy
