Our research focuses on the mechanisms underlying cytokine action in the central nervous system (CNS) using an integrative and multidisciplinary strategy organized through supracellular (behavioral analysis by computerized monitoring systems), cellular (extracellular and intracellular neurophysiological recording), and molecular (patch-clamp recording, and DNA, RNA and protein analyses) approaches...
We investigated the effectiveness of lipopolysaccharide (LPS) and muramyl dipeptide (MDP) administered into the brain to induce anorexia in acutely fasted Wistar rats allowed to refeed. We also assayed for changes in mRNA levels of IL-1 system components, TNF-α, TGF-β1, glycoprotein 130 (gp 130), leptin receptor (OB-R), pro-opiomelanocortin (POMC), neuropeptide Y (NPY), glucocorticoid receptor (GR),...
