Mycobacterium tuberculosis is associated with the activation of cytokine circuits both at sites of active tuberculosis in vivo and in cultures of mononuclear cells stimulated by M. tuberculosis or its components in vitro. Interactive stimulatory and/or inhibitory pathways are established between cytokines, which may result in potentiation or attenuation of the effects of each molecule on T-cell...

Background: The preclinical evaluation of novel immune therapies demands humanized mouse models with functional human cells. In previous studies we have established a system T- B- and NK cells, as well monocytes in immunodeficient mice by transfer hematopoietic stem cells (HSCs) or peripheral blood mononuclear (PBMC). By transplantation cell-line-derived (CDX) patient-derived (PDX) tumor xenogr...

The stress of parturition in the dairy cow is associated with increased susceptibility to infectious disease. During the periparturient period the demands for calcium are increased; these increased demands for calcium can result in subclinical or clinical hypocalcemia. Periparturient cows also experience significant immune suppression. Because intracellular calcium signaling is a key early feat...

BACKGROUND Measurement of HIV DNA-bearing cells in cerebrospinal fluid (CSF) is challenging because few cells are present. We present a novel application of the sensitive droplet digital (dd)PCR in this context. METHODS We analyzed CSF cell pellets and paired peripheral blood mononuclear cells (PBMC) from 28 subjects, 19 of whom had undetectable HIV RNA (<48 copies/mL) in both compartments. W...

atherosclerosis is a chronic inflammatory disease of the arterial wall characterized by innate and adaptive immune responses to a variety of microbial and self-antigens. given the crucial role of adaptive immunity in the pathogenesis of atherosclerosis, this study was performed to investigate the proliferative response of peripheral blood mononuclear cells (pbmc) and interleukin (il)-2 producti...

Attempts to refine and improve outcome predictions using tumor gene expression have been recently reported. We show that peripheral blood mononuclear cell (PBMC)-associated gene signatures can predict outcome in non-small cell lung carcinoma patients independent of demographic data or TNM staging, and that this information may persist after tumor resection.

Patients with pemphigus vulgaris (PV) may develop autoimmunity against an array of non-desmoglein antigens, including keratinocyte acetylcholine receptors. The latter, along with yet unknown autoantigens, could participate to PV pathogenesis. Here, we report a case of PV developing autoimmunity against peripheral blood mononuclear cell (PBMC) antigens. The patient was poorly responsive to stero...

Juvenile Idiopathic Arthritis (JIA) is one of the most common chronic disease conditions affecting children in the USA. As with many rheumatic diseases, there is growing interest in using genomic technologies to develop biomarkers for either diagnosis or to guide treatment ("personalized medicine"). Here, we explore the use of gene expression patterns in peripheral blood mononuclear cells (PBMC...

patients and methods in the present cross-sectional study, 109 patients with established hiv infection, who visited a governmental and referral center for hiv screening in tehran (tehran west health center (twhc)) between may 2014 and july 2015 were enrolled according to the convenience sample strategy. after peripheral blood collection, isolation of plasma and peripheral blood mononuclear cell...

The purpose of the current study was to evaluate the anti-inflammatory activity of tetramethlpyrazine on oxazolone-induced colitis mice. Spleen mononuclear cells (SMC), lamina propria mononuclear cells (LPMC) and peripheral blood mononuclear cells (PBMC) were isolated from oxazolone-induced colitis and normal mice. The colitis cells treated by oxazolone were randomly divided into model, low dos...
