Effects of in vitro exposure to arachidonic acid on TNF-alpha production by murine peritoneal macrophages.

abstract：:We have previously reported that human airway macrophages do not respond to the beta-adrenoceptor agonist isoprenaline. The airway macrophage is known to be derived from the blood monocyte. In this study we have assessed the effect of beta-adrenoceptor stimulation on human monocytes matured into macrophages in vitro, ...

Thus, we speculated that beta2 integrins could support attachment to E-selectin. To test this hypothesis, we coated 10-microm-diameter microspheres wit...
