OBJECTIVES This study was conducted to evaluate the anti-inflammatory effects of besifloxacin, a novel fluoroquinolone under clinical evaluation for treatment of ophthalmic infections. METHODS Cytokine expression in human THP-1 monocytes was stimulated by lipopolysaccharide (LPS), and Luminex technology was used to determine the effect of besifloxacin on LPS-induced cytokine expression. Moxif...

Following infection, naive T cells are activated in the secondary lymphoid tissue, but then need to move to the infected tissue in the periphery to mediate their effector functions. The acquisition of inflammatory chemokine receptors, such as CCR5 and CCR6, may contribute to the efficient relocation of activated T cells to inflamed sites in the periphery. In keeping with this idea, the present ...

Neutrophil (polymorphonuclear leukocyte [PMN]) sequestration is one of the histologic hallmarks of an acute inflammatory response. During the natural evolution of an inflammatory response, PMNs are often replaced by mononuclear cells. This shift in the elicitation of specific leukocyte populations usually occurs as the inflammatory lesion enters either the repair/resolution stage or progresses ...

RATIONALE Macrophage accumulation in adipose tissue associates with insulin resistance and increased cardiovascular disease risk. We previously have shown that generation of reactive oxygen species and monocyte chemotactic factors after exposure of adipocytes to saturated fatty acids, such as palmitate, occurs via translocation of NADPH oxidase 4 into lipid rafts (LRs). The anti-inflammatory ef...

Eosinophils, the major immune effector cells contributing to allergic inflammation and asthma, are profoundly affected by interleukin (IL) 5 with respect to their differentiation, viability, recruitment, and cytotoxic effector functions. IL-5 enhances eosinophil responsiveness to a variety of chemotactic factors via a process called priming, although the molecular mechanism is unknown. In this ...

fusion of two genes at dna level produces a single protein, known as a chimeric protein. immunotoxins are chimeric proteins composed of specific cell targeting and cell killing moieties. bacterial or plant toxins are commonly used as the killing moieties of the chimeric immunotoxins. in this investigation, the catalytic domain of shiga-like toxin (a1) was fused to human granulocyte macrophage c...

Myristicin (1-allyl-5-methoxy-3,4-methylenedioxybenzene) is an active aromatic compound found in nutmeg (the seed of Myristica fragrans), carrot, basil,cinnamon, and parsley. Myristicin has been known to have anti-cholinergic, antibacterial,and hepatoprotective effects, however, the effects of myristicin on virus-stimulated macrophages are not fully reported. In this study, the anti-inflammator...

Wear particle-induced periprosthetic osteolysis remains the principal cause of aseptic loosening of orthopaedic implants. Monocytes/macrophages phagocytose wear particles and release cytokines that induce inflammatory response. This response promotes osteoclast differentiation and osteolysis. The precise mechanisms by which wear particles are recognized and induce the accumulation of inflammato...

Lactoferrin, an 80-kDa iron-binding protein with immune modulating properties, is a unique adjuvant component able to enhance efficacy of the existing Mycobacterium bovis Bacillus Calmette Guerin (BCG) vaccine to protect against murine model of tuberculosis. Although identified as having effects on macrophage presentation events, lactoferrin's capability to modulate dendritic cells (DCs) functi...
