Exosomes are small extracellular vesicles that carry lipids, proteins, and microRNAs (miRNAs). They are released by all cell types and can be found not only in circulation but in many biological fluids. Exosomes are essential for interorgan communication because they can transfer their contents from donor to recipient cells, modulating cellular functions. The miRNA content of exosomes is responsible for most of their biological effects, and changes in exosomal miRNA levels can contribute to the progression or regression of metabolic diseases. As exosomal miRNAs are selectively sorted and packaged into exosomes, they can be useful as biomarkers for diagnosing diseases. The field of exosomes and metabolism is expanding rapidly, and researchers are consistently making new discoveries in this area. As a result, exosomes have great potential for a next-generation drug delivery platform for metabolic diseases.
外泌体是携带脂质、蛋白质和 microRNAs(miRNAs)的小型细胞外囊泡。它们由所有细胞类型释放,不仅存在于循环中,也存在于许多生物体液中。外泌体对于器官间的通讯至关重要,因为它们可以将内容物从供体细胞传递到受体细胞,从而调节细胞功能。外泌体的 miRNA 含量负责其大部分生物学效应,外泌体 miRNA 水平的变化可能导致代谢疾病的进展或消退。由于外泌体中的 miRNA 被选择性地分拣并包装到外泌体中,因此它们可以作为诊断疾病的生物标志物。外泌体与代谢领域的研究正在迅速扩展,研究人员在该领域不断有新的发现。因此,外泌体在代谢疾病的下一代药物递送平台方面具有巨大的潜力。
