  • Patent number: 11510891
    Abstract: A production of a drug, wherein the drug is specific for SH-SY5Y neuroblastoma cancer by loading caffeic acid phenethyl ester (CAPE) to a plurality of microvesicles that a specialized skin cell leaves into a nutrient solution. The objective of the present invention is to provide a cell-specific targeted vesicle development by loading the CAPE to the plurality of microvesicles obtained as a result of culturing and subsequent specialization of a plurality of tissue cells; and to use the CAPE at lower concentrations compared to a state of the art applications to minimize a toxicity of the CAPE to both a plurality of cells other than a plurality of targeted cells and a body.

  • Publication number: 20220331230
    Abstract: A use of plant exosomes as a product having the effect of enhancing viability and, by stimulating the hair follicles, enhancing hair growth in skin cells. The plant exosomes are used to revitalize and strengthen unhealthy skin and hair that have lost their vitality, to stop hair loss, to provide faster hair growth by stimulating hair follicles, and to provide a regulating effect in improving the effects such as wrinkles and age spots caused by aging skin cells. The plant exosomes are isolated from single, double, or triple combinations of plants selected from a group consisting of pineapple plant, garlic plant, and pomegranate plant. For example, a triple combination includes 1 ng-1 mg of the plant exosomes isolated from the pineapple plant, 1 ng-10 ?g of the plant exosomes isolated from the garlic plant, and 1 ng-1 mg of plant exosomes isolated from the pomegranate plant.

  • Publication number: 20220288146
    Abstract: Plant exosomes can be used to reduce the protein aggregates formed in the cells and the damage they cause to the cells. Plant exosomes are of plant origin and not transgenic, and thus, they are reliable as an alternative to the drugs used in the treatment of neurodegenerative diseases, particularly ALS. Moreover, compared to the conventional applications, plant exosomes can provide a product with high efficacy and no side effects which can be produced in high amounts and at affordable prices due to the fact that it is plant-derived.

  • Publication number: 20220226393
    Abstract: Use of parasites and extracellular vesicles obtained from the parasites for a cancer treatment is provided. The use of parasites and extracellular vesicles obtained from parasites is for using in a treatment of a cancer, and loading an active substance on exosomes by using a drug loading capacity of exosomes, and thus, by carrying a specific drug directly to target cancer cells without causing any side effect on healthy cells and to enhance a bioavailability of the specific drug, achieving a desired effect in a tumor specific target region. Particularly Leishmania infantum parasite is used as a source for the extracellular vesicles.

  • Publication number: 20220062348
    Abstract: A cartilage is generated by a formulation, wherein the formulation is produced by an isolated septal cartilage exosome released by cells isolated from a septal cartilage to a medium. The objective of the isolated septal cartilage exosome is to generate the cartilage to be used in a treatment of cartilage tissue defects, such as osteoarthritis or arthrosis, since the cartilage induces a cartilage formation and also suppresses an inflammatory response.
