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. 11,857,574.

Summary of the Inventive Concept

The inventive concept adapts genetically engineered T cells with Regnase-1 and/or TGFBRII disruption for specific, narrow markets or unique operational environments, enhancing their functionality and persistence in high-security, disaster relief, extreme weather, remote, or high-altitude settings.

Background and Problem Solved

The original patent disclosed genetically engineered T cells with Regnase-1 and/or TGFBRII disruption for CAR-T cell therapy. However, these cells may not be optimized for specific, challenging operational environments. This inventive concept addresses the limitations of the original patent by adapting the genetically engineered T cells for high-security, disaster relief, extreme weather, remote, or high-altitude settings, ensuring improved persistence and potency in these unique contexts.

Detailed Description of the Inventive Concept

The inventive concept comprises genetically engineered T cells with Regnase-1 and/or TGFBRII disruption, designed to operate in specific, narrow markets or unique operational environments. For high-security CAR-T cell manufacturing, the T cells are engineered to withstand enhanced security protocols. For disaster relief CAR-T cell therapy, the T cells are adapted to function optimally in extreme environmental conditions. For extreme weather CAR-T cell therapy, the T cells are designed to function optimally in extreme temperatures and humidity. For remote CAR-T cell manufacturing, the T cells are engineered to be manufactured and administered in a remote or isolated location. For CAR-T cell therapy in high-altitude environments, the T cells are adapted to function optimally in low-oxygen conditions.

Novelty and Inventive Step

The inventive concept's novelty lies in the adaptation of genetically engineered T cells with Regnase-1 and/or TGFBRII disruption for specific, narrow markets or unique operational environments, which is non-obvious compared to the original patent. The inventive step is the recognition of the need for specialized CAR-T cell therapies for these unique contexts and the development of tailored solutions.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include adapting the genetically engineered T cells for other unique operational environments, such as space exploration or high-radiation settings. Variations could include using different gene editing systems or targeting other genes to enhance the T cells' functionality and persistence.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the biotechnology and pharmaceutical industries, particularly in the development of CAR-T cell therapies for high-security, disaster relief, extreme weather, remote, or high-altitude settings. The target market includes hospitals, research institutions, and biotech companies operating in these unique contexts.
