Intestinal angiopoietin-like protein 4: New regulatory roles in lipid transport and metabolism, lipoprotein assembly and secretion, and molecular mechanisms of action

肠道是消化和运输营养物质的器官，确保所有组织的生长和存活。最近的突破已经揭示了胃肠道（GI）的关键作用，如产生过多的GI肽。在消化道内，上皮细胞与大量微生物共存，称为微生物群。微生物和宿主细胞都表现出相互适应的变化，这些变化是许多管家和重要功能所需的，并确保在生物体的一生中维持适当水平的微量营养素和常量营养素。总的来说，所有系统都能确保最佳的营养运输，同时保持肠道屏障的完整性，并抵御氧化应激（OxS）和炎症负担。更重要的是，肠道细胞和肠道微生物群之间的双向相互作用也是与外周器官和整体稳态相互作用的核心。

The intestine is an organ for the digestion and transport of nutrients, assuring growth and survival of all tissues. Recent breakthroughs have unveiled critical roles of the gastrointestinal (GI) tract such as the production of the plethora of the GI peptides. Within the digestive tract, epithelial cells coexist with large numbers of microorganisms, referred to as the microbiota. Both the microorganisms and the host cells display mutual adaptive changes required for numerous housekeeping and vital functions and safeguarding the maintenance of appropriate levels of micro-and macronutrients over the lifetime of the organism. Overall, all the systems ensure optimal nutrient transportation while maintaining intestinal barrier integrity and defending against oxidative stress (OxS) and inflammation burden. In an even more important fashion, bidirectional interactions between intestinal cells and the commensal microbiota are also central to the crosstalk with peripheral organs and integral homeostasis.
