Intracellular control of metabolite ratios for immunosuppressive therapies
Innovative poly(alpha-ketoglutarate) nanoparticles control intracellular metabolite ratios in immune cells, inducing immunosuppressive responses. Validated in rheumatoid arthritis models, these nanoparticles target multiple sclerosis, promising a new therapeutic approach.
Overview
This innovative solution involves controlling intracellular metabolite ratios using poly(alpha-ketoglutarate) nanoparticles to induce immunosuppressive responses in immune cells. The technology specifically targets the succinate to alpha-ketoglutarate ratio, a critical factor in modulating immune responses. Successfully demonstrated in rheumatoid arthritis models, this approach is now being applied to multiple sclerosis (EAE model), aiming to decrease mitochondrial activity and glycolysis, thereby enhancing immunosuppressive responses.
Technical specifications
- Poly(alpha-ketoglutarate) Nanoparticles: Designed to be phagocytosed by immune cells like macrophages and dendritic cells.
- Mechanism of Action: By increasing the alpha-ketoglutarate to succinate ratio, these nanoparticles reduce mitochondrial activity and glycolysis, leading to immunosuppressive effects.
- Applications: Proven efficacy in rheumatoid arthritis collagen-induced models and currently being validated for multiple sclerosis using EAE models in mice.
Technology readiness level
The technology is at TRL 6, having been demonstrated in relevant environments with plans for further validation in multiple sclerosis models, aiming for long-term treatment efficacy.
