    摘要: Use of the effects of plant exosomes on the immune system as immune system enhancers, silencers and modulators against diseases is disclosed. The plant derived exosomes are obtained from at least one portion of the plant selected from the group consisting of the entire plant, fruit, leaf, seed, root, or differentiated tissues like the plant's tissue culture medium, stem cell, waste material, shell or phloem. In the scope of the invention, the plant exosomes having immunomodulatory effects are used mainly in autoimmune diseases, and in cell, tissue, organ transplantations and in Graft Versus Host disease as immune system enhancers, suppressors or, if necessary, as modulators performing both of the first two functions.

    摘要: A method of producing plant-derived exosomes from plant tissue culture based cell suspension cultures is provided. The method includes: obtaining the plant tissue culture based cell suspension culture; mixing the the plant tissue culture based cell suspension culture with an isolation solution; centrifuging to obtain a supernatant and an infranatant; and obtaining the plant-derived exosomes from the infranatant. The objective of the present invention is to produce homogenous plant exosomes with high volume and purity by making use of the advantages of the plant suspension culture to be used for purposes such as therapeutics and drug carriers.
