Exosomes are a promising diagnostic marker of oncological diseases, which can be detected in the early stages. Vita Motus focus is the research of exosomes as a means of cancer diagnosis and treatment. Exosom Functions Exosomes are a promising diagnostic marker of oncological diseases, which can be detected in the early stages. One of the main functions of exosomes in the body is information exchange between cells. In the context of this functionality, exosomes can be divided into three categories. The first is “scouts”, exchanging which cells learn what is happening around them, and, taking this into account, adapt to changes. The second are exosomes, which report the need for regeneration of the affected area of the body. The third is exosomes that send information (by changing the expression profile of a certain set of RNA molecules or detecting mutations in DNA) about the onset of the development of a pathological process, oncology or inflammation. In this light, studies of the diagnostic and therapeutic potential of exosomes are of particular value for the healthcare system of any state, due to the possibility of timely diagnosis of many diseases, thereby saving money spent on their treatment and subsequent rehabilitation. Exosom Benefits As a result of our research, it was found that the use of exosomes can increase the bioavailability of medicine for humans. This effect is achieved due to the loading of medicine into exosomes, which can reduce the dosage and, as a result, the risk of developing undesirable effects, and at the same time increase the accuracy of medicine delivery to the targeted cell. The addition of local injection of exosomes, which are natural participants in regenerative processes, accelerates the recovery of damaged organs. Studies have also shown the efficacy and benefits of exosomes derived from plants and animal biological fluids. In particular, the exosomes can be obtained from goat milk, which is better absorbed by the human body. The use of exosomes of plant and animal origin for different treatments has already caused a solid resonance in the world. Exosomes can be introduced into the body both locally and in the form of oral solutions. Vadim Pospelov has a number of patented medical researches and inventions, in particular in the field of cancer treatment. One of them is a method of immunotheraphy for cancer diseases. The invention relates to medicine, in particular to oncology, and can be used to treat patients diagnosed with leukemia.
