Garlic-derived exosomes ease acute liver failure by inhibiting CCR2/CCR5. (Zhao X, et al., 2023)Applications of Garlic-Derived Exosomes
Garlic-Derived Exosomes in Therapeutics
1. Cancer Therapy
One of the most promising applications of garlic-derived exosomes is in cancer treatment. Research has shown that garlic-derived exosomes can induce apoptosis in cancer cells by activating the caspase-mediated pathway. Caspases are enzymes that play essential roles in programmed cell death. By triggering these enzymes, garlic-derived exosomes help to selectively kill cancer cells without harming normal cells. Additionally, garlic-derived exosomes inhibit angiogenesis, and the formation of new blood vessels, which is crucial for tumor growth and metastasis.
2. Neuroprotection
Garlic-derived exosomes have shown potential in neuroprotection by interacting with brain acid soluble protein 1 (BASP1) in microglia through their phosphatidic acid content. This interaction inhibits the c-Myc/STING/IFNIDO1 inflammatory signaling cascade, reducing microglial inflammation and preventing nerve cell death. This mechanism suggests that garlic-derived exosomes could be valuable in treating neurodegenerative diseases and other conditions characterized by excessive inflammation and neuronal damage.
3. Colitis Treatment
Inflammatory bowel diseases (IBD), including colitis, may also benefit from GDE therapy. Studies in mice have demonstrated that garlic-derived exosomes ameliorate colitis via the TLR4/MyD88/NF-κB pathway and by modulating the intestinal microbiota. The ability of garlic-derived exosomes to regulate these pathways highlights their potential as a natural therapeutic option for managing IBD and maintaining gut health.
4. Metabolic Health
Garlic-derived exosomes contain a unique microRNA, miR-396e, which has been shown to modulate interactions between macrophages and adipocytes. This regulation of glycolytic enzyme genes reduces inflammation in adipocytes, highlighting a potential strategy for treating obesity-related inflammation. Furthermore, miR-396e also modulates interactions between macrophages and hepatocytes, alleviating high-fat diet-induced liver dysfunction and inflammation, indicating a role for garlic-derived exosomes in managing metabolic disorders.
5. Anti-inflammatory Effects
Garlic-derived exosomes have demonstrated the ability to inhibit the migration of monocytes to the liver and reduce macrophage infiltration, thus ameliorating inflammatory outbreaks. This anti-inflammatory effect is primarily achieved by inhibiting CCR2/CCR5 signaling pathways, offering a novel approach to managing chronic inflammatory conditions.The Diagnostic Applications of Garlic-Derived Exosomes
Exosomes are increasingly being explored as diagnostic tools due to their ability to carry disease-specific biomarkers. Garlic-derived exosomes, enriched with garlic's bioactive compounds, could serve as a novel diagnostic platform. By isolating and analyzing garlic-derived exosomes from bodily fluids, it might be possible to detect specific biomarkers associated with various diseases, leading to early and accurate diagnosis.
Garlic-Derived Exosomes in Skin Care and Cosmetic Industry
1. Anti-aging and Skin Rejuvenation
The anti-inflammatory and antioxidant properties of garlic-derived exosomes make them suitable for skincare applications. These exosomes can help reduce oxidative stress and inflammation in the skin, which are major contributors to aging. By promoting cellular repair and rejuvenation, garlic-derived exosomes can help maintain youthful and healthy skin.
2. Hair Growth Promotion
Garlic-derived exosomes have been found to promote hair growth by upregulating key growth factors such as platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), and transforming growth factor-β1 (TGF-β1) through the Wnt/β-catenin signaling pathway. This property makes garlic-derived exosomes a potential treatment for hair loss and related conditions.
3. Wound Healing
The ability of garlic-derived exosomes to modulate inflammatory responses and promote cellular regeneration can also be harnessed for wound healing. By enhancing the skin's natural repair mechanisms, garlic-derived exosomes can accelerate wound healing and improve skin health.

Case Study
Case study 1: Özkan İ, 2021
In this research, nanoscale extracellular vesicles originating from garlic were meticulously isolated and characterized through nanoparticle tracking analysis, electron microscopy, and the use of antibodies specific to the vesicle surface. In assessing their potential to combat cancer, cell lines of A498 human kidney carcinoma and A549 human lung carcinoma were employed as experimental models, alongside normal human dermal fibroblasts. Utilizing Annexin V/PI staining, coupled with an in-depth analysis of the expression levels of both apoptotic mRNA and proteins, it was observed that the garlic-derived exosomes triggered the intrinsic apoptotic cascade. Furthermore, the application of these vesicles notably diminished the expression of the angiogenesis-promoting VEGF protein in cancer cells. Notably, the garlic-derived exosomes specifically induced apoptotic cell death in cancerous cells, leaving the normal cells unharmed. This pioneering study presents evidence that plant exosomes are capable of initiating caspase-mediated apoptosis, presenting a groundbreaking alternative for cancer therapy.

Figure 1. Garlic-derived exosomes have been shown to impact the cell cycle progression in A498 and A549 cancer cells, as demonstrated by flow cytometry. Treatment with these vesicles for 24 and 48 hours resulted in a significant increase in the proportion of cells in the S phase, while the number of cells in the G0/G1 phase notably decreased. This effect was less pronounced in HDF cells, suggesting that garlic exosomes selectively target the cell cycle of cancer cells, potentially contributing to their growth inhibition without significantly affecting normal dermal fibroblast cells.Case study 2: Yuksel E I, 2023
This study explored the impact of garlic exosome (GE) on hair growth in rats, utilizing a controlled experimental design. The research involved the application of different concentrations of GE and measured various hair growth parameters and protein levels associated with hair follicle development. Results indicated that GE significantly increased the number of anagen follicles and follicle diameter, particularly in the higher concentration group. Furthermore, the study found that GE elevated the levels of proteins involved in hair growth pathways, such as Wnt-1, β-catenin, VEGF, PDGF, and TGF-β1, suggesting that GE promotes hair growth through these signaling mechanisms.
