asthma is a chronic inflammatory disorder of the airways. the stress is a factor for asthma which indicates a disorder in the function of communicational mediators of nervous and immunological systems such as neurotransmitters. a study indicated that blood serotonin concentration increases in asthmatic patients. other study indicates that one kind of the serotonin receptors, named 5ht...
Cryopreservation is the method of choice for long term storage of human PBMCs. This study was designed to compare the different combinations of variables affecting the cryopreservation of PBMCs samples. The viability of PBMCs separated from 2×5 ml peripheral blood samples obtained from 16 healthy adult volunteers, were measured using trypan blue dye exclusion method just before freezing with di...
BACKGROUND Natural products are used in the production of therapeutic drugs due to their wide diversity and excellent adaptability to biological structures. Sesquiterpene lactones are the active constituents of several plants from the Asteraceae family. AIM To assess the in vitro effect of a sesquiterpene lactone (millerenolide). MATERIAL AND METHODS The drug effect was assessed measuring t...
DNA methylation plays an important role in biological processes in human health and disease. Recent technological advances allow unbiased whole-genome DNA methylation (methylome) analysis to be carried out on human cells. Using whole-genome bisulfite sequencing at 24.7-fold coverage (12.3-fold per strand), we report a comprehensive (92.62%) methylome and analysis of the unique sequences in huma...
Human peripheral blood mononuclear cells (PBMCs) are the key drivers of the immune responses. These cells undergo activation, proliferation and differentiation into various subsets. During these processes they initiate metabolic reprogramming, which is coordinated by specific gene and protein activities. PBMCs as a model system have been widely used to study metabolic and autoimmune diseases. H...
The densities of surface immunoglobulin (slg) on peripheral blood mononuclear cells (PBM) of normals and patients with chronic lymphocytic leukemia (CLL), chronic lymphosarcoma cell leukemia (LCL), and hairy cell leukemia (HCL) were analyzed using the fluorescence-activated cell sorter (FACS). PBM were labeled with fluorescein conjugates of F(ab')2 fragments of affinity chromatography-purified ...
The receptors for fibronectin (FN-R) and vitronectin (VN-R) belong to a family of integral membrane glycoproteins known to be involved in cell-extracellular matrix and cell-cell interactions named integrins (FN-R = beta 1 integrin and VN-R = beta 3 integrin). Adhesion studies using FN-coated plastic dishes and highly purified subpopulations of peripheral blood mononuclear cells (PBMCs) showed a...
Cellular immunity to cartilage proteoglycans may be responsible for sustaining chronic inflammation in ankylosing spondylitis. This hypothesis was examined by measuring peripheral blood and synovial fluid mononuclear cell proliferation in five preparations of human cartilage proteoglycan monomer in vitro. Peripheral blood mononuclear cells from 25 patients and synovial fluid mononuclear cells f...
INTRODUCTION There are conflicting data on the ability of human mononuclear cells to produce nitric oxide (NO). We investigated nitric oxide production from peripheral blood mononuclear cells (PBMs) by using a new sensitive fluorescent indicator. MATERIALS AND METHODS PBMs from healthy volunteers were collected, plated in 96-well microplates, and loaded with the fluorescent nitric oxide probe...
