Background: Atherosclerosis, a chronic inflammatory disease of the vessel wall is characterized by local and systemic immune responses to a variety of antigens. Oxidized low-density lipoprotein (oxLDL) is considered as an important determining factor in the pathogenesis of atherosclerosis. Objective: The purpose of this study was to investigate the degree of peripheral blood mononuclear cells (...

PURPOSE The aim of this study was to estimate the production of interleukin-15 (IL-15) by neutrophils (PMNs) and peripheral blood mononuclear cells (PBMC) confronted with the serum levels of IL-15 in patients with Lyme disease. MATERIAL AND METHODS PMN and PBMC were isolated from heparinized whole blood of patients. The cells were incubated for 18 hs at 37 degrees C in a humidified incubator ...

Abstract Despite the availability of a safe and effective vaccine, measles still causes significant mortality morbidity among children in developing countries. As disease that induces immune amnesia with increased susceptibility to other infections but also life-long immunity measles, little is known about immunogenetics B cells elicit measles-specific antibodies (Abs) natural infection vs vacc...

INTRODUCTION Th17 cells have been implicated in the pathogenesis of rheumatoid arthritis (RA). The aim of this study was to systematically analyse the phenotype, cytokine profile and frequency of interleukin-17 (IL-17) producing CD4-positive T cells in mononuclear cells isolated from peripheral blood, synovial fluid and synovial tissue of RA patients with established disease, and to correlate c...

Using sled dogs as exercise model, our objectives of this study were to 1) assess the effects of one acute bout of high-intensity exercise on surface GLUT4 concentrations on easily accessible peripheral blood mononuclear cells (PBMC) and 2) compare our findings with published research on exercise induced GLUT4 in skeletal muscle. During the exercise bout, dogs ran 5 miles at approximately 90% o...

As soon as Peripheral Blood Mononuclear Cells (PBMC) are isolated from whole blood, some cells begin dying. The rate of apoptotic cell death is increased when PBMC are shipped, cryopreserved, or stored under suboptimal conditions. Apoptotic cells secrete cytokines that suppress inflammation while promoting phagocytosis. Increased numbers of apoptotic cells in PBMC may modulate T cell functions ...

The proliferative responsiveness of granulocyte colony-stimulating factor (G-CSF)-mobilized blood was studied in uni-directional mixed leukocyte cultures. Unfractionated mononuclear cells from mobilized blood obtained by leukapheresis at day 4 after initiation of G-CSF (G-PBMC) were hyporesponsive (31.5% +/- 9.2% response, P = .003) compared to mononuclear cells obtained from the peripheral blo...

Perivascular lesions within the central nervous system (CNS) of rats with hyperacute experimental autoimmune encephalomyelitis (HEAE) contained large numbers of peripheral blood mononuclear cells (PBMC) and polymorphonuclear leukocytes (PMN), cells enzymatically capable of producing reactive nitrogen and oxygen intermediates (RNI and ROI), which, in excess, are mediators of tissue damage. PBMC ...

Introduction/Objectives: To analyse the infl uence of shortand long-term glatiramer acetate (GA) treatment on expression patterns of cell surfacebound adhesion molecules (AM) on peripheral blood mononuclear cells (PBMC) from patients with relapsing remitting multiple sclerosis (RRMS). BACKGROUND: GA is baseline therapy for the treatment of RRMS. It is known to reduce relapse frequencies and to ...
