Splenic denervation blocks leptin-induced enhancement of humoral immunity in Siberian hamsters (Phodopus sungorus).

abstract：BACKGROUND/AIM:Somatostatin (SST) analogs are mainstay for controlling tumor proliferation and hormone secretion in carcinoid patients. Recent data suggest that extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation may potentiate the anti-tumor effects of SST analogs in carcinoids. Additionally, ERK1/2 pho...
