The prevalence of health problems in the offspring of pregnant diabetic mothers has recently been verified. Therefore, the present study was designed to investigate the influence of dietary camel whey protein (CWP), administered as a supplement to streptozotocin (STZ)-induced diabetic pregnant mice, on the efficiency of the immune system of the offspring. Three groups of female mice (n = 10) were used: non-diabetic control mice, diabetic mice, and diabetic mice orally administered CWP during the pregnancy and lactation periods. We then tested the immune response of B and T cells in adult male offspring (n = 15 in each group) by using flow cytometry, western blotting, and ELISAs. Our data demonstrated that the offspring of diabetic dams exhibited several postpartum complications, such as significant aberrant overexpression of activating transcription factor-3 (ATF-3), significant elevation of the plasma levels of pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α) and reactive oxygen species (ROS), marked decreases in the plasma levels of IL-2 and IL-7, significant inhibition of CCL21- and CXCL12-mediated chemotaxis of B- and T-lymphocytes, and a marked decrease in the proliferative capacity of antigen-stimulated B- and T-lymphocytes. Interestingly, administration of CWP to diabetic dams substantially restored the expression of ATF-3 and the levels of ROS, pro-inflammatory cytokines, IL-2, and IL-7 in the offspring. Furthermore, the chemotaxis of B- and T-lymphocytes toward CCL21 and CXCL12 and the proliferative capacities of these lymphocytes were restored in the male offspring of diabetic mice administered CWP. Our data provide evidence of a protective role of CWP in decreasing the tendency of the offspring of diabetic mothers to develop diabetes and related complications.
近期已证实,妊娠糖尿病母亲的后代中健康问题的患病率较高。因此,本研究旨在调查饮食中补充骆驼乳清蛋白(CWP)对链脲佐菌素(STZ)诱导的糖尿病妊娠小鼠后代免疫系统效率的影响。使用了三组雌性小鼠(每组n = 10):非糖尿病对照小鼠、糖尿病小鼠以及在妊娠和哺乳期口服CWP的糖尿病小鼠。然后,我们通过流式细胞术、蛋白质印迹法和酶联免疫吸附测定法检测了成年雄性后代(每组n = 15)中B细胞和T细胞的免疫反应。我们的数据表明,糖尿病母鼠的后代出现了多种产后并发症,如激活转录因子3(ATF-3)显著异常过度表达、促炎细胞因子(IL-1β、IL-6和TNF-α)和活性氧(ROS)血浆水平显著升高、IL-2和IL-7血浆水平显著降低、CCL21和CXCL12介导的B淋巴细胞和T淋巴细胞趋化作用受到显著抑制,以及抗原刺激的B淋巴细胞和T淋巴细胞增殖能力显著下降。有趣的是,给糖尿病母鼠施用CWP可显著恢复后代中ATF-3的表达以及ROS、促炎细胞因子、IL-2和IL-7的水平。此外,在施用CWP的糖尿病小鼠雄性后代中,B淋巴细胞和T淋巴细胞对CCL21和CXCL12的趋化作用以及这些淋巴细胞的增殖能力得到了恢复。我们的数据提供了证据,证明CWP在降低糖尿病母亲后代患糖尿病及相关并发症倾向方面具有保护作用。
