Perturbation in lipid homeostasis is one of the major bottlenecks in metabolic diseases, especially Non-alcoholic Fatty Liver Disease (NAFLD), which has emerged as a leading global cause of chronic liver disease. The bile acids (BAs) and their derivatives exert a variety of metabolic effects through complex and intertwined pathways, thus becoming the attractive target for metabolic syndrome treatment. To modulate the lipid homeostasis, the role of BAs, turn out to be paramount as it is essential for the absorption, transport of dietary lipids, regulation of metabolic enzymes and transporters that are essential for lipid modulation, flux, and excretion. The synthesis and transport of BAs (conjugated and unconjugated) is chiefly controlled by nuclear receptors and the uptake of long-chain fatty acids (LCFA) and BA conjugation via transporters. Among them, from in-vivo studies, farnesoid X receptor (FXR) and liver-specific fatty acid transport protein 5 (FATP5) have shown convincing evidence for their key roles in lipid homeostasis and reversal of fatty liver disease substantially. BAs have a wider range of biological effects as they are identified as modulators for FXR and FATP5 both and therefore hold a significant promise for altering the lipid content in the treatment of a metabolic disorder. BAs also have received noteworthy interest in drug delivery research due to its peculiar physicochemical properties and biocompatibility. Here, we are highlighting the connecting possibility of BAs as an agonist for FXR and antagonist for FATP5, paving an avenue to target them for designing synthetic small molecules for lipid homeostasis.

胆汁酸介导 FXR 和 FATP5 之间在脂质代谢调节中的潜在功能相互作用。

脂质体内平衡的扰动是代谢疾病的主要瓶颈之一,尤其是非酒精性脂肪肝 (NAFLD),它已成为全球慢性肝病的主要原因。胆汁酸(BAs)及其衍生物通过复杂且相互交织的途径发挥多种代谢作用,从而成为代谢综合征治疗的有吸引力的靶点。为了调节脂质稳态,BAs 的作用变得至关重要,因为它对膳食脂质的吸收、运输、代谢酶和转运蛋白的调节至关重要,这些酶和转运蛋白对脂质调节、通量和排泄至关重要。BAs(共轭和非共轭)的合成和转运主要受核受体和长链脂肪酸 (LCFA) 的摄取以及通过转运蛋白的 BA 共轭控制。其中,在体内研究中,法尼醇 X 受体 (FXR) 和肝脏特异性脂肪酸转运蛋白 5 (FATP5) 已显示出令人信服的证据,证明它们在脂质稳态和脂肪肝疾病逆转中的关键作用。BAs 具有更广泛的生物学效应,因为它们被确定为 FXR 和 FATP5 的调节剂,因此在治疗代谢紊乱时具有改变脂质含量的重要前景。由于其特殊的物理化学性质和生物相容性,BAs 在药物递送研究中也受到了显着的关注。在这里,我们强调了 BA 作为 FXR 激动剂和 FATP5 拮抗剂的连接可能性,为靶向它们以设计用于脂质稳态的合成小分子铺平了道路。法尼醇 X 受体 (FXR) 和肝脏特异性脂肪酸转运蛋白 5 (FATP5) 已显示出令人信服的证据,证明它们在脂质稳态和逆转脂肪肝疾病中的关键作用。BAs 具有更广泛的生物学效应,因为它们被确定为 FXR 和 FATP5 的调节剂,因此在治疗代谢紊乱时具有改变脂质含量的重要前景。由于其特殊的物理化学性质和生物相容性,BAs 在药物递送研究中也受到了显着的关注。在这里,我们强调了 BA 作为 FXR 激动剂和 FATP5 拮抗剂的连接可能性,为靶向它们以设计用于脂质稳态的合成小分子铺平了道路。法尼醇 X 受体 (FXR) 和肝脏特异性脂肪酸转运蛋白 5 (FATP5) 已显示出令人信服的证据,证明它们在脂质稳态和逆转脂肪肝疾病中的关键作用。BAs 具有更广泛的生物学效应,因为它们被确定为 FXR 和 FATP5 的调节剂,因此在治疗代谢紊乱时具有改变脂质含量的重要前景。由于其特殊的物理化学性质和生物相容性,BAs 在药物递送研究中也受到了显着的关注。在这里,我们强调了 BA 作为 FXR 激动剂和 FATP5 拮抗剂的连接可能性,为靶向它们以设计用于脂质稳态的合成小分子铺平了道路。
