Onion-derived Exosome Research and Application

Research on onion-derived exosomes holds the promise of bringing innovative applications and solutions to the fields of medicine, drug delivery, healthcare, and skincare. Creative Biolabs has the capability to assist clients in gaining a deeper understanding of onions.

The Value of Onions

Onions are a versatile and nutrient-rich superfood that offers a wide range of health benefits.

  • Nutrient-Rich: Onions are packed with essential nutrients, including carbohydrates, protein, dietary fiber, vitamin C, and vitamin A. These nutrients play vital roles in maintaining overall health.
  • Cardiovascular Health: Onions contain compounds like allicin and prostaglandin, which can help lower cholesterol levels, reduce blood
  • Mental Alertness and Energy: Onion's sulfur compounds stimulate tear gland secretion, promoting alertness, increasing metabolism, enhancing energy levels, and reducing fatigue.
  • Digestive Aid: Compounds in onions stimulate digestive gland secretions, aiding in digestion and promoting gastrointestinal health.
  • Anti-Aging and Skin Health: Onions contain sulfur and essential vitamins that help delay skin aging, remove age spots, and promote skin health. Anthocyanins in purple-skinned onions provide powerful antioxidant protection.
  • Immune Support: Onions have antibacterial properties and can help prevent colds and flu by resisting viruses and bacteria.
  • Weight Management: Pickled onions in vinegar can contribute to weight management by aiding in fat burning and preventing fat accumulation. Onion's dietary fiber also supports healthy bowel movements.
  • Cancer Prevention: Onions contain quercetin, a potent natural anti-cancer substance that helps control the growth of cancer cells and reduce the risk of cancer.

In addition to their nutritional value, onion extracts offer versatile applications:

  • Anti-Inflammatory: Extracts from onions have anti-inflammatory and antimicrobial properties, aiding in wound healing and reducing inflammation.
  • Scar Lightening: Onion extracts, such as creams and oils, are used to lighten scars without damaging the skin.
  • Calcium Supplementation: Onion extracts contain calcium, which supports bone density and may help prevent osteoporosis.

Research on Onion-derived Exosomes

Based on the above content, exosomes derived from onions may contain a variety of bioactive molecules, and these molecules may have a plethora of untapped therapeutic potentials that warrant further investigation.

Title: Onion (Allium cepa L.)-derived nanoparticles inhibited LPS-induced nitrate production, however, their intracellular incorporation by endocytosis was not involved in this effect on RAW264 cells.

Research Objective: To evaluate the effectiveness of onion-derived exosomes as anti-inflammatory agents.

Research Methods:

  1. Onion-derived exosomes were extracted from onions using techniques such as ultracentrifugation and filtration, and their physical properties, including particle size and composition, were analyzed.
  2. The contents of onion-derived exosomes were analyzed through nucleic acid electrophoresis, protein staining, and high-performance liquid chromatography.
  3. Onion-derived exosomes were added to the culture medium of RAW264 cells to assess their cytotoxicity and their impact on nitrate production induced by bacterial lipopolysaccharides (LPS).
  4. Onion-derived exosomes were labeled with PKH26 fluorescent dye to observe whether they were taken up by cells and to study the mechanism of cellular internalization by adding different endocytosis inhibitors.

Research Results:

  1. Onion-derived exosomes contain proteins, miRNA, and flavonoid compounds, with quercetin and its glycosides being the main flavonoids.
  2. Onion-derived exosomes significantly inhibited nitrate production in RAW264 cells induced by LPS without causing cytotoxicity. The anti-inflammatory effect was concentration-dependent and remained effective at low concentrations.
  3. Inhibition of endocytosis did not completely prevent the incorporation of onion-derived exosomes and their inhibition of nitrate production induced by LPS. This suggests that the anti-inflammatory effect of onion-derived exosomes is not mediated through an endocytic mechanism.

Conclusion: Onion-derived exosomes exhibit anti-inflammatory properties, and their anti-inflammatory effect is not mediated through endocytosis. This implies that consuming minimally processed onions may provide effective anti-inflammatory benefits without compromising the structural and functional integrity of these exosomes.
