Leptin and adiponectin stimulate the release of proinflammatory cytokines and prostaglandins from human placenta and maternal adipose tissue via nuclear factor-κB, peroxisomal proliferator-activated receptor-γ and extracellularly regulated kinase 1/2

Abstract

Beyond their effects on central metabolic functions, leptin, resistin, and adiponectin have profound effects on a number of other physiologic processes, including immune function and inflammation. Although leptin, resistin, and adiponectin are produced in human placenta and adipose tissue, their immunoregulatory actions in these tissues are not known. Therefore, the aim of this study was to determine the effect of leptin, resistin, and adiponectin on the release of proinflammatory mediators in human placenta and sc adipose tissue. Samples were obtained from normal pregnancies at the time of cesarean section. Tissue explants (n = 5) were incubated in the absence (basal control) or presence of..
