Abstract (original English)
Somatostatin (SRIF) is a well-known neuroendocrine secretion product. SRIF expression and secretion are induced after inflammation in murine macrophages and in endotoxin-injected sheep and pigs. Because adipocytes have been demonstrated to produce numerous cytokines and peptide hormones, we investigated the expression of SRIF and its receptors (SSTR1-5) in human adipose tissue after inflammatory stimulation in vitro and in tissues from patients with septic disease.Preadipocyte-derived adipocytes, mesenchymal stem cell-derived adipocytes, and mature explanted adipocytes expressed SRIF-mRNA after endotoxin [lipopolysaccharide (LPS)] or IL-1beta treatments. LPS- and IL-1beta-mediated SRIF-mRNA induction was blocked by pretreatment with dexamethasone. Using cocultures and quantitative real-time PCR, we demonstrate adipocyte SRIF induction by secretion factors from activated peripheral blood mononuclear cell-derived macrophages. In contrast to basal adipocytes, SRIF protein was detected in culture supernatants of LPS-treated and of combined TNFalpha/IL-1beta/LPS-treated adipocytes. SRIF protein was visualized by immunohistochemistry in explanted minced adipose tissue after overnight incubation in culture medium supplemented with combined IL-1beta and LPS. In septic patients, expression of SRIF-mRNA and SRIF protein was found in visceral, but not in sc, adipose tissue. Adipocyte mRNA
