The plasticity of the coordination chemistry Lanthanoid ions (LnIII) has allow design novel compounds with slow relaxation magnetization since first Single Ion Magnet (SIMs) was reported by Ishikawa, who used phthalocyaninate ligand to make a “sandwich type” complex. allowed possibility different types molecular complexes SIMs behaviour based on organic ligands. There is also inorganic ligands,...

introduction: umbilical cord blood is a rich source of hematopoietic cells and can be used in the clinical setting for hematopoietic cell transplantation in graft versus host disease (gvhd). a number of different drugs have been used as prophylaxis against gvhd including corticosteroids, cyclosporine a (cy a) and fk506. in this study, the in vitro effects of fk506 on cord blood mononuclear cell...

We examined human immunodeficiency virus (HIV) production in cultured mononuclear cells from 36 seropositive homosexual males. Production was detected by using an HIV p24 antigen ELISA assay in blood mononuclear cells in 54% of asymptomatic, 71% of acquired immunodeficiency syndrome (AIDS)-related complex, and 100% of AIDS patients. When the peripheral blood mononuclear cells were separated int...

Caffeine is the most widely used neurostimulant in the world. There is considerable debate on its effect on immune cells as it has been shown to antagonize adenosine receptors (ARs), which mediate an anti-inflammatory switch in activated immune cells. A second target is phosphodiesterase, where it acts as an inhibitor. If the primary effect of caffeine on mononuclear phagocytes were to antagoni...

Angiotensin II (Ang-II) exerts inflammatory activity and is involved in different cardiovascular disorders. This study has evaluated the involvement of TNFα in the leukocyte accumulation elicited by Ang-II. Ang-II (1 nmol/L, i.p., in rats) induced TNFα release at 1h followed by neutrophil and mononuclear cell recruitment. The administration of an anti-rat TNFα antiserum had no effect on Ang-II-...

Asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthase, is elevated in hypercholesterolemia. This study was designed to determine the role of ADMA in the increased mononuclear cell adhesiveness observed in human hypercholesterolemia. In patient studies, plasma ADMA levels were determined by high-performance liquid chromatography. Functional mononuclear leukocyte ad...

Acute allograft rejection is a major complication postlung transplantation and is the main risk factor for the development of bronchiolitis obliterans syndrome. Acute rejection is characterized by intragraft infiltration of activated mononuclear cells. The ELR-negative CXC chemokines CXCL9, CXCL10, and CXCL11) are potent chemoattractants for mononuclear cells and act through their shared recept...

Gram-negative bacterial pneumonia is a common and dangerous infection with diminishing treatment options due to increasing antibiotic resistance among causal pathogens. The mononuclear phagocyte system is a heterogeneous group of leukocytes composed of tissue-resident macrophages, dendritic cells, and monocyte-derived cells that are critical in defense against pneumonia, but mechanisms that reg...

RATIONALE Toll-like receptors 2 and 4 (TLR2, TLR4) enable cellular responses to bacterial lipoproteins, LPS, and endogenous mediators of cell damage. They have an established role in the activation of leukocytes, endothelial cells, and some smooth muscle cell types, but their roles in airway smooth muscle are uncertain. OBJECTIVES To determine the roles of TLRs in activation of airway smooth ...

Dendritic cells (DCs), monocytes, and macrophages are a heterogeneous population of mononuclear phagocytes that are involved in antigen processing and presentation to initiate and regulate immune responses to pathogens, vaccines, tumor, and tolerance to self. In addition to their afferent sentinel function, DCs and macrophages are also critical as effectors and coordinators of inflammation and ...
