Background: Common variable immunodefi ciency (CVID) is a heterogeneous group of disorders, characterized by decreased immunoglobulin levels in serum and increased susceptibility to recurrent infections, autoimmunity, and malignancy. The pathogenesis of CVID is still unknown. Objectives: This study was performed to investigate T-helper (TH) 1 and 2 cytokine levels in patients with CVID. Materia...

Tear film is a complex mixture of lipids, proteins and minerals which covers the external surface of the eye, thereby providing lubrication, nutrition and protection to the underlying cells. Analysis of tears is an emerging area for the identification of biomarkers for the prediction, diagnosis, and prognosis of various ocular diseases. Tears are easily accessible and their collection is non-in...

p300, a ubiquitous transcription coactivator, plays an important role in gene activation. Our previous work demonstrated that human inducible nitric oxide synthase (hiNOS) expression can be highly induced with the cytokine mixture (CM) of TNF-α + IL-1β + IFN-γ. In this study, we investigated the functional role of p300 in the regulation of hiNOS gene expression. Our initial data showed that ove...

AIM To determine if cytokine release with a solid phase assay is predictive of adverse responses for a range of therapeutic mAbs. METHODS Cytokine ELISAs and a multi-array system were used to compare responses generated by different therapeutic mAbs using a solid phase assay. Flow cytometry was employed to determine the cellular source of those cytokines. RESULTS Only TGN1412 and muromonab-...

This unit describes a general method for immunoenzymetric assay of mouse and human cytokines. The technique is based on use of two anti-cytokine monoclonal antibodies (MAbs), each specific for a spatially distinct determinant on the cytokine. One of these is a coating antibody, and the other is a derivatized detecting antibody. A support protocol describes chemical labeling of anti-cytokine mon...

OBJECTIVE Glioblastoma cells produce cytokines with proinflammatory or immunosuppressive properties, or both, which, in addition to altered p53 gene expression, have been shown to be associated with glioblastoma resistance to radiotherapy. The reported data concerning cytokines have been isolated and sometimes discordant, and a comprehensive profile analysis of cytokines and their corresponding...

There is widespread interest in the immunostimulatory effects of food-derived substances that are expected to contribute improving human health. Broccoli ( Brassica oleracea var. italica ) has been shown contain potent polysaccharides for developing food materials with immunomodulatory function. In this study, activity previously uncharacterized broccoli was assessed using a silkworm Bombyx mor...

introduction: helicobacter pylori (h. pylori), is a bacterium responsible for upper gastrointestinal tract diseases. the 16s rrna is a common h. pylori gene which are usually preferred for diagnosis purpose. the aim of this study was to determine the prevalence and abundance of 16s rrna in fecal samples and also evaluate correlation between the level of 16s rrna and activities of the cytokines,...

background: the water-soluble extract of ganoderma lucidum (reishi) has been used as an immunomodulator to stimulate spleen cells proliferation and cytokine expression. objective: to investigate the effect of ganoderma lucidum (g. lucidum) on cytokine production by mice peritoneal macrophages. methods: mice peritoneal macrophages were prepared by intra-peritoneal injection of 5 ml cold pbs. per...

Background and Objectives: Infection with human immunodeficiency virus (HIV) results in dysregulation of the cytokine profile. A switch from a T helper 1 (Th1) to a Th2 cytokine has been proposed as an important factor in progression of HIV infection to AIDS. The aim of the present study was to assess the level of Th1 and Th2 cytokines in HIV infected individuals in order to identify t...
