Enhanced Therapeutic Microvesicle Production and Application

This inventive concept introduces a novel method and system for producing high-quality therapeutic microvesicles from probiotic bacteria, enhancing their therapeutic effect, and providing a kit for their production. It addresses the limitations of existing microvesicle production methods and improves the efficiency, safety, and efficacy of therapeutic microvesicle-based treatments.

The original patent disclosed therapeutic microvesicles of probiotic bacteria, but the production process was not optimized, and the microvesicles' therapeutic effect was not fully explored. The new inventive concept solves the problems of inefficient microvesicle production, limited therapeutic effect, and lack of standardization in the production process.

The new inventive concept comprises a method for producing therapeutic microvesicles from probiotic bacteria by culturing the bacteria in a specific pH and temperature-controlled culture medium, followed by centrifugation and filtration to separate the microvesicles. A system for therapeutic microvesicle production is also disclosed, consisting of a bioreactor, a microvesicle separation module, and a purification module. Additionally, a therapeutic microvesicle composition is described, comprising microvesicles with a defined size range and immune response-inducing capabilities. The inventive concept further includes a method for enhancing the therapeutic effect of therapeutic microvesicles by combining them with a specific prebiotic compound and a kit for producing therapeutic microvesicles, comprising a culture medium, a probiotic bacterial strain, and instructions for culturing and separating the microvesicles.

The new inventive concept introduces a novel method and system for producing high-quality therapeutic microvesicles, enhancing their therapeutic effect, and providing a kit for their production. The inventive step lies in the specific combination of culturing conditions, separation methods, and purification steps, as well as the integration of these components into a comprehensive system. The enhancement of the therapeutic effect through the combination with a prebiotic compound is also a novel aspect.

Alternative embodiments of the inventive concept include the use of different probiotic bacterial strains, varying the culturing conditions, and modifying the separation and purification methods. Variations of the therapeutic microvesicle composition could include different size ranges, surface modifications, or loading with additional therapeutic compounds.

The enhanced therapeutic microvesicle production and application concept has significant commercial potential in the fields of probiotics, microbiome research, and immunotherapy. The target market includes pharmaceutical and biotechnology companies, research institutions, and hospitals, with potential applications in the treatment of various diseases, such as inflammatory bowel disease, cancer, and autoimmune disorders.
