Is neutrophil activation attenuated by high-density lipoprotein and apolipoprotein A-I in in vitro and in vivo models of inflammation?
We describe here a novel role for HDL and apoA-I in regulating neutrophil activation using in vitro, in vivo, and clinical approaches. We also show that these effects of HDL and apoA-I involve a mechanism requiring changes in membrane domain content rather than in cholesterol efflux per se.
BPD-DS is associated with markedly suppressed ghrelin levels, possibly contributing to the longlasting weight-reducing effect of the procedure. Leptin levels decreased and adiponectin increased, as expected, after weight loss. Sleeve gastrectomy with resection of the gastric fundus seems to be the main cause of the postoperative reduction in ghrelin levels.
