This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,573.

Summary of the Inventive Concept

A novel approach to restimulate cryopreserved immune cells, microorganisms, and plant cells to enhance metabolic performance, applicable to various industries including sports, medicine, agriculture, and bioremediation.

Background and Problem Solved

The original patent focused on restimulating cryopreserved tumor infiltrating lymphocytes for cancer treatment. However, the limitations of this approach lie in its specificity to cancer therapy. The new inventive concept addresses this limitation by applying the core technology to entirely different industries, leveraging the potential of cryopreserved cell restimulation to enhance metabolic performance.

Detailed Description of the Inventive Concept

The new inventive concept involves restimulating cryopreserved cells to enhance specific metabolic pathways, depending on the target application. For instance, in athletic performance, cryopreserved immune cells are restimulated to enhance anaerobic metabolism, increasing endurance and reducing fatigue. In neurodegenerative diseases, cryopreserved immune cells are restimulated to promote mitochondrial metabolism, reducing oxidative stress and inflammation. Similarly, in agriculture, cryopreserved plant immune cells are restimulated to enhance glycolytic metabolism, increasing resistance to pathogens and environmental stressors.

Novelty and Inventive Step

The new claims introduce a paradigm shift in the application of cryopreserved cell restimulation, moving beyond cancer treatment to address unmet needs in diverse industries. The inventive step lies in recognizing the potential of this technology to enhance metabolic performance and developing specific methods for each target application.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include restimulating cryopreserved cells for enhanced lipid metabolism in cosmetic applications, or for improved ATP production in bioenergy generation. Variations of the method could involve using different types of cryopreserved cells, such as stem cells or dendritic cells, or combining restimulation with other therapies, like gene editing or small molecule inhibitors.

Potential Commercial Applications and Market

The inventive concept has far-reaching commercial potential, with applications in sports medicine, pharmaceuticals, agriculture, bioremediation, and cosmetics. The target market includes athletes, patients with neurodegenerative diseases, farmers, bioremediation companies, and cosmetic manufacturers, among others.

Field of Art

Cellular immunotherapy, specifically tumor infiltrating lymphocyte (TIL) manipulation, cell cryopreservation, and metabolic restimulation techniques in oncological and translational research
