Metabolic changes have been linked to the development of inflammatory bowel disease (IBD), which includes colitis. Allulose, an endogenous bioactive monosaccharide, is vital to the synthesis of numerous compounds and metabolic processes within living organisms. Nevertheless, the precise biochemical mechanism by which allulose inhibits colitis remains unknown. Allulose is an essential and intrinsic protector of the intestinal mucosal barrier, as it maintains the integrity of tight junctions in the intestines, according to the current research. It is also important to know that there is a link between the severity of inflammatory bowel disease (IBD) and colorectal cancer (CRC), chemically-induced colitis in rodents, and lower levels of allulose in the blood. Mice with colitis, either caused by dextran sodium sulphate (DSS) or naturally occurring colitis in IL-10 mice, had less damage to their intestinal mucosa after being given allulose. Giving allulose to a colitis model starts a chain of reactions because it stops cathepsin B from ejecting and helps lysosomes stick together. This system effectively stops the activity of myosin light chain kinase (MLCK) when intestinal epithelial damage happens. This stops the breakdown of tight junction integrity and the start of mitochondrial dysfunction. To summarise, the study's findings have presented data that supports the advantageous impact of allulose in reducing the advancement of colitis. Its ability to stop the disruption of the intestinal barrier enables this. Therefore, allulose has potential as a medicinal supplement for treating colitis.
代谢变化与炎症性肠病 (IBD) 的发展有关,其中包括结肠炎。阿洛酮糖是一种内源性生物活性单糖,对生物体中许多化合物和代谢过程的合成至关重要。然而,阿洛酮糖抑制结肠炎的确切生化机制尚不清楚。根据目前的研究,阿洛酮糖是肠道黏膜屏障的重要内在保护剂,因为它维持肠道中紧密连接的完整性。同样重要的是要知道,炎症性肠病 (IBD) 的严重程度与结直肠癌 (CRC) 之间存在联系,化学诱导的啮齿动物结肠炎与血液中阿洛酮糖水平较低有关。用葡聚糖硫酸钠 (DSS) 或 IL-10 小鼠中自然发生的结肠炎引起结肠炎的小鼠,在用阿洛酮糖处理后,其肠道黏膜损伤较少。给结肠炎模型给予阿洛酮糖会引发一系列反应,因为它阻止组织蛋白酶 B 排出,并帮助溶酶体粘在一起。当肠道上皮细胞受损时,该系统可有效阻止肌球蛋白轻链激酶 (MLCK) 的活性。这阻止了紧密连接完整性的破坏和线粒体功能障碍的开始。总之,该研究的发现提供了数据支持阿洛酮糖在减少结肠炎进展方面的有利影响。它阻止肠道屏障破坏的能力使其具有这种潜力。因此,阿洛酮糖有可能作为治疗结肠炎的药物补充剂。
