Resveratrol Attenuates LPS-induced Apoptosis via Inhibiting NF- κ B Activity in Chicken Peripheral Lymphocyte Cultures

ABSTRACT This study aims to investigate whether resveratrol (RES) could inhibit NF-κB activity and protect in vitro cultured chicken lymphocytes from apoptosis induced by continuous LPS stimulation. Blood lymphocytes of chickens were collected and cultured. LPS was added to the samples of treatment group, while the same volume of normal saline (NS) was supplemented to those of the control group. In the treatment groups, four different concentrations of RES (0, 20, 40, and 80 µg/ml) were admixed. Then, the following indicators were tested: lymphocyte apoptotic rate, lymphocyte viability, NF-κB activity, TNF-a level, reactive oxygen species (ROS), and expression of apoptosis-related proteins (Fas/FasL and Caspase-8). The results indicated that the application of different concentrations of RES could significantly increase the viability of lymphocytes and decrease the apoptotic rate (p
