Stimulatory effect of immobilized glycans on macrophages in vitro.

Abstract:

:Mouse macrophages were cultured on chemically modified plastic dishes. On dishes covered with immobilized glycans, the macrophages were stimulated as judged by increased 14C-glucosamine incorporation, increased cytostatic and cytolytic capacities and by morphology as seen by scanning electron microscopy. The corresponding soluble glycans did not have the capacity to stimulate macrophages as measured by these criteria. Plastic surfaces covered with polyethylenimine showed stimulation of the macrophages with regard to some of the parameters measured. These results may indicate that the stimulation is a multistep process and that, contrary to earlier findings, it is not a prerequisite for stimulation that the glycan be intracellular. The results support the idea that a fixed steric arrangement of glycans is necessary for the stimulation of macrophages in vitro.

  • IL-17 induces expression of vascular cell adhesion molecule through signalling pathway of NF-κB, but not Akt1 and TAK1 in vascular smooth muscle cells.

    abstract::Interleukin-17 (IL-17) plays an important role in several autoimmune diseases. IL-17 can induce the expression of vascular cell adhesion molecule (VCAM-1) in aortic vascular smooth muscle cells (SMCs), which is important for the development of atherosclerosis.
