本试验旨在研究二十碳五烯酸(EPA)、二十二碳六烯酸(DHA)以及两者以2:1的比例组合对脂多糖(LPS)刺激下肉鸡肠道B淋巴细胞信号通路的影响。结果表明,与对照组相比,这些处理显著降低了前列腺素E2 (PGE(2))、环氧合酶2 (COX-2)和磷脂酶C (PLC)的产生(P< 0.05),显著提高了肌醇三磷酸(IP3)的浓度(P< 0.05)。与单独使用EPA或DHA相比,两者联合(2:1)降低了PGE(2)、COX-2和PLC的产量,提高了IP3的浓度(P< 0.05)。因此,EPA和DHA通过干扰磷脂酰肌醇信号通路和第二信使通路抑制lps刺激的B淋巴细胞增殖。
The present study was conducted to investigate the effects of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and a combination of both at a ratio of 2:1 on the signalling pathways in lipopolysaccharide (LPS)-stimulated intestinal B lymphocytes from broiler chickens. The results showed that these treatments reduced the production of prostaglandin E2 (PGE(2)), cyclooxygenase 2 (COX-2), and phospholipase C (PLC) and increased the concentration of inositol triphosphate (IP3) significantly compared with the control group (P<.05). Compared with EPA or DHA alone, the combination of both (2:1) reduced the production PGE(2), COX-2, and PLC and increased the concentration of IP3 (P<.05). Therefore, EPA and DHA suppressed the LPS-stimulated proliferation of B lymphocytes by interfering with phosphatidylinositol signalling and the second messenger pathways.
